Commit Pinned } horizontal /> Livepeer Contracts Arbiscan
On-chain Canonical } horizontal /> Livepeer uses a system of Ethereum smart contracts to permissionlessly govern its decentralised network. The [Livepeer Protocol](https://github.com/livepeer/protocol/tree/delta) is deployed on [Arbitrum One](https://arbiscan.io/accounts/label/livepeer) and uses these contracts to govern: * Livepeer Token (LPT) ownership and delegation * Staking and selection of active Orchestrators * Distribution of inflationary rewards and fees to participants * Time-based progression of the protocol through rounds * Payment processing through a probabilistic micropayment system ## Livepeer Contracts There are three categories of contracts in the Livepeer Protocol as well as migration contacts: 1. **[Core Protocol Contracts](#core-protocol-contracts)** – staking, payments, round progression, and service discovery 2. **[Token and Utility Contracts](#token-and-utility-contracts)** – the LPT token and bridge infrastructure 3. **[Governance Contracts](#governance-contracts)** – on-chain voting, proposal execution, and treasury management 4. **[Migration Contracts](#migration-contracts)** – historical Confluence upgrade contracts, migration complete ```mermaid theme={"theme":{"light":"github-light","dark":"dark-plus"}} %%{init: {'theme': 'base', 'themeVariables': {'primaryColor': '#18794E', 'primaryTextColor': '#fff', 'primaryBorderColor': '#3CB540', 'lineColor': '#3CB540', 'mainBkg': '#18794E', 'nodeBorder': '#3CB540', 'clusterBkg': 'transparent', 'clusterBorder': '#3CB540', 'titleColor': '#3CB540', 'edgeLabelBackground': 'transparent', 'textColor': '#3CB540', 'nodeTextColor': '#fff'}}}%% graph TB subgraph "Registry" Controller["Controller\nContract Registry"] end subgraph "Discovery" ServiceRegistry["ServiceRegistry\nOrchestrator URI Mapping"] AIServiceRegistry["AIServiceRegistry\nAI Capability Registration"] end subgraph "Economic" LPT["LivepeerToken\nERC-20"] BondingManager["BondingManager\nStaking & Rewards"] TicketBroker["TicketBroker\nMicropayments"] Minter["Minter\nToken Inflation"] end subgraph "Time" RoundsManager["RoundsManager\nProtocol Rounds"] end subgraph "Governance" BondingVotes["BondingVotes\nStake Checkpointing"] Governor["Governor\nUpgrade Executor"] LivepeerGovernor["LivepeerGovernor\nOn-chain Voting"] Treasury["Treasury\nProtocol Treasury"] end subgraph "Participants" Gateway["Gateway Node"] Orchestrator["Orchestrator Node"] Delegator["LPT Holder"] end Controller -.->|"Address Lookup"| LPT Controller -.->|"Address Lookup"| BondingManager Controller -.->|"Address Lookup"| TicketBroker Controller -.->|"Address Lookup"| RoundsManager Controller -.->|"Address Lookup"| Minter Controller -.->|"Address Lookup"| ServiceRegistry Controller -.->|"Address Lookup"| BondingVotes Controller -.->|"Address Lookup"| LivepeerGovernor Controller -.->|"Address Lookup"| Treasury Delegator -->|"approve() LPT"| LPT Delegator -->|"bond(amount, orch)"| BondingManager Delegator -->|"castVote()"| LivepeerGovernor BondingManager -->|"transferFrom()"| LPT BondingManager -->|"checkpointBondingState()"| BondingVotes Orchestrator -->|"transcoder(rewardCut, feeShare)"| BondingManager Orchestrator -->|"setServiceURI(url)"| ServiceRegistry Orchestrator -->|"reward()"| BondingManager BondingManager -->|"createReward()"| Minter Minter -->|"mint() new LPT"| LPT Minter -->|"trustedTransferTokens()"| Treasury Gateway -->|"fundDepositAndReserve()"| TicketBroker Orchestrator -->|"redeemWinningTicket()"| TicketBroker TicketBroker -->|"winningTicketTransfer()"| LPT RoundsManager -->|"currentRound()"| BondingManager RoundsManager -->|"blockHashForRound()"| TicketBroker BondingVotes -->|"getPastVotes()"| LivepeerGovernor LivepeerGovernor -->|"execute()"| Governor Governor -->|"setContractInfo()"| Controller ``` ## Core Protocol Contracts The core protocol contracts manage staking, delegation, reward distribution, round progression, payment processing, and service discovery. The Controller serves as the central registry – upgrading a contract means registering a new target implementation address via the Controller, while the proxy address remains stable. ```mermaid theme={"theme":{"light":"github-light","dark":"dark-plus"}} %%{init: {'theme': 'base', 'themeVariables': {'primaryColor': '#18794E', 'primaryTextColor': '#fff', 'primaryBorderColor': '#3CB540', 'lineColor': '#3CB540', 'mainBkg': '#18794E', 'nodeBorder': '#3CB540', 'clusterBkg': 'transparent', 'clusterBorder': '#3CB540', 'titleColor': '#3CB540', 'edgeLabelBackground': 'transparent', 'textColor': '#3CB540', 'nodeTextColor': '#fff'}}}%% graph LR D[Delegator] -->|"bond / unbond"| BM[BondingManager] O[Orchestrator] -->|"register / reward"| BM O -->|"set URI"| SR[ServiceRegistry] G[Gateway] -->|"fund deposit"| TB[TicketBroker] O -->|"redeem ticket"| TB BM -->|"create reward"| M[Minter] M -->|"mint LPT"| LPT[LivepeerToken] TB -->|"pay fees"| LPT RM[RoundsManager] -.->|"round timing"| BM RM -.->|"block hash"| TB ``` *** #### **Controller** Arbitrum One The Controller is the central registry for all protocol contracts. Every other contract resolves peer contract addresses by calling `getContract(keccak256(""))` on the Controller. Upgrades are applied by registering a new implementation address under the same name hash – the proxy addresses never change. } title="Controller"/>}> *Verified · Controller registry · Active* **Purpose**: * Central address registry for all protocol contracts * Enables contract upgrades while keeping proxy addresses stable * Provides `pause()`/`unpause()` for emergency system-wide halts * Owner is the Governor contract – all upgrades must go through governance **Key functions** (from `Controller.sol`): Look up a registered contract by keccak256 name hash Returns address and git commit hash Register or update a contract; callable by owner (Governor) only Halt all contracts that check `controller.paused()` Resume all contracts that check `controller.paused()` Update the Controller reference in a registered contract **Contract** } filename="Controller.sol" /> #### **BondingManager** Arbitrum One The BondingManager is the most critical economic contract in the protocol. It manages the active Orchestrator pool as a sorted doubly-linked list, handles all LPT bonding and unbonding, and distributes inflationary rewards and fees each round. The `feeShare` in the protocol is defined as: **the percentage of fees paid to Delegators by the transcoder (Orchestrator)**. It is not the Gateway's cut – it is the Orchestrator's share of fees that they pass on to their Delegators. Source: `BondingManager.sol` includes this as struct comment: "// % of fees paid to Delegators by transcoder". } title="BondingManager" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved · Target V13* **Purpose**: * Manages the active Orchestrator pool (sorted by stake using SortedDoublyLL) * Handles `bond()`, `unbond()`, and `withdrawStake()` for all Delegators * Distributes inflationary LPT rewards to Orchestrators and their Delegators each round * Manages the unbonding period – Delegators must wait `unbondingPeriod` rounds before withdrawing * Tracks per-round earnings pools for each Orchestrator * Calls `checkpointBondingState()` on BondingVotes on every state change for governance weight * Since Delta upgrade: sends `treasuryRewardCutRate` fraction of each reward to Treasury; contributions halt automatically when treasury balance exceeds `treasuryBalanceCeiling` **Slashing:** `slashTranscoder()` exists in the contract but is currently inoperative: the Verifier role is set to the null address (`0x000...`). Slashing could be re-enabled via governance by configuring the Verifier role and making necessary compatibility updates. It is out of scope for current audits. **Key functions** (from `BondingManager.sol`, `delta` branch): Delegate LPT stake to an Orchestrator Begin withdrawal; creates an unbonding lock, starts the unbonding period Cancel unbonding and re-bond stake to current delegate Re-bond to a new Orchestrator from unbonded state Complete withdrawal after unbonding period expires Withdraw accumulated ETH fees to a recipient address Register as an Orchestrator or update parameters; `_rewardCut` is % of reward kept by Orchestrator; `_feeShare` is % of fees passed to Delegators Called by active Orchestrators each round to mint inflationary LPT and distribute to earnings pool Claim accumulated rewards and fees. Note: `_endRound` is unused; earnings are always claimed through the current round regardless of the value passed. Publicly callable function to fix a stale voting power checkpoint for any account. Useful for operators after an inconsistent state. Transfer ownership of a bond (or portion) to a new Delegator. Used for stake migrations between wallets. Returns unclaimed pending stake for a Delegator through the current round Returns unclaimed pending ETH fees for a Delegator through the current round Returns Orchestrator state: lastRewardRound, rewardCut, feeShare, activationRound, deactivationRound, cumulativeRewards, cumulativeFees, lastFeeRound Returns Delegator state: bondedAmount, fees, delegateAddress, delegatedAmount, startRound, lastClaimRound, nextUnbondingLockId **Contract** } filename="BondingManager.sol" /> #### **TicketBroker** Arbitrum One The TicketBroker implements Livepeer's off-chain probabilistic micropayment (PM) system. Gateways pre-fund a deposit and reserve on-chain; they send lottery tickets to Orchestrators off-chain with each transcoding job. Orchestrators redeem winning tickets on-chain to claim payment. This amortises per-segment payment costs across many tickets. } title="TicketBroker" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved* **Purpose**: * Holds Gateway ETH deposits and reserves * Validates and settles winning probabilistic payment tickets * Manages the unlock period before Gateways can withdraw funds * Tracks claimed reserves per Orchestrator per round to prevent over-redemption * Emits `WinningTicketRedeemed` (ticket redemption attempt) and `WinningTicketTransfer` (ETH actually moved) events used for on-chain payment monitoring **Key functions** (from `MixinTicketBrokerCore.sol`): Gateway adds ETH to deposit (payable) Gateway adds ETH to reserve (payable) Fund both deposit and reserve in one call (payable); msg.value must equal the sum of both amounts Fund deposit and reserve on behalf of another address (payable) Orchestrator redeems a winning ticket; transfers ETH to fee pool via BondingManager. Emits both `WinningTicketTransfer` and `WinningTicketRedeemed`. Gateway initiates the withdrawal unlock period; emits `Unlock` Gateway cancels an in-progress unlock; emits `UnlockCancelled` Gateway withdraws all deposit and reserve after unlock period; emits `Withdrawal` Returns full sender state: deposit amount, withdrawRound, and reserve info Returns whether a sender has an unlock in progress **Contract** } filename="TicketBroker.sol" /> #### **RoundsManager** Arbitrum One The RoundsManager defines the protocol's time unit. A round is a fixed number of Arbitrum blocks. The current round must be initialised before Orchestrators can call `reward()`. It stores per-round block hashes used as randomness for ticket validation. } title="RoundsManager" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved* **Purpose**: * Tracks the current round number and round length in blocks * Stores block hashes per round for ticket randomness (used by TicketBroker) * Enforces the round lock period – Orchestrators cannot change parameters during the lock window at end of each round * `initializeRound()` must be called at the start of each new round before reward calls proceed **Key functions** (from `RoundsManager.sol`): Initialise a new round; callable by any address; updates block hash store and LIP upgrade rounds Returns current round number Returns whether the current round has been initialised Returns whether the current round is in its lock period Returns the stored block hash for a given round Returns round length in blocks Returns lock period as a percentage of round length (MathUtils percPoint) **Contract** } filename="RoundsManager.sol" /> #### **Minter** Arbitrum One The Minter controls LPT token inflation. Each round it calculates the mintable token supply based on the configured inflation rate. Since the Delta upgrade (LIP-91), a configurable fraction of each round's reward is minted to the Treasury rather than solely to Orchestrators and Delegators. } title="Minter" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active* **Purpose**: * Manages LPT token inflation schedule * Calculates mintable tokens per round based on current `inflation` rate and total LPT supply * Adjusts inflation up or down each round based on actual bonding rate vs `targetBondingRate` * Called by BondingManager during Orchestrator `reward()` calls – not called directly * Holds ETH received from TicketBroker redemptions and disburses to Orchestrators **Key functions** (from `Minter.sol`): Called only by BondingManager; mints a fraction of mintable tokens for the round as a reward Transfer LPT to an address; callable by BondingManager only Burn LPT; callable by BondingManager only Withdraw ETH to an address; callable by BondingManager only Receive ETH from TicketBroker on ticket redemption (payable) Returns LPT mintable in the current round Returns LPT already minted in the current round Returns current inflation rate as a MathUtils percPoint value Returns per-round inflation adjustment amount Returns the target bonding rate that inflation adjusts towards **Contract** } filename="Minter.sol" /> #### **ServiceRegistry** Arbitrum One The ServiceRegistry stores each Orchestrator's publicly advertised HTTPS service URI on-chain. Gateway nodes query this registry during network initialisation to discover Orchestrators. Each update emits a `ServiceURIUpdate` event that off-chain indexers track. } title="ServiceRegistry" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved* **Purpose**: * Allows Orchestrators to register and update their service endpoint URIs * Enables Gateway nodes to discover Orchestrators when using `-network arbitrum-one-mainnet` * Not used when a Gateway specifies `-orchAddr` directly **Key functions** (from `ServiceRegistry.sol`): Orchestrator registers or updates their HTTPS endpoint; emits `ServiceURIUpdate(address indexed _addr, string _serviceURI)` Returns the registered URI for a given Orchestrator address **Contract** } filename="ServiceRegistry.sol" /> #### **AIServiceRegistry** Arbitrum One A standalone ServiceRegistry for AI subnet Orchestrators. Detached from the Controller – its address is hardcoded in go-livepeer (`starter.go`) rather than resolved dynamically. Deployed by a different deployer than the main protocol contracts. } title="AIServiceRegistry" />}> **Address (Arbitrum One)**: *Verified · Deployment artifact confirmed · Runtime consumer confirmed · Active* **Purpose**: * Stores service URI and capability metadata for AI-enabled Orchestrators * Used when a node is started with `-aiServiceRegistry` flag * Same interface as ServiceRegistry (`setServiceURI`, `getServiceURI`) ## Token and Utility Contracts The LivepeerToken contract originates on Ethereum Mainnet and is bridged to Arbitrum One via paired Gateway contracts, with a BridgeMinter handling L1 mint operations. All active protocol operations use the Arbitrum One representation. LPT must be bridged before it can be staked, delegated, or used for payments. Livepeer moved from Ethereum Mainnet to Arbitrum One in 2022 (the Confluence upgrade) to increase throughput and reduce fees. On Ethereum Mainnet, only the `LivepeerToken` and `BridgeMinter` contracts remain operational.

The governance system consists of four contracts working together: BondingVotes checkpoints voting power, LivepeerGovernor manages proposal voting, Treasury holds protocol funds, and Governor executes approved upgrades. ```mermaid theme={"theme":{"light":"github-light","dark":"dark-plus"}} %%{init: {'theme': 'base', 'themeVariables': {'primaryColor': '#18794E', 'primaryTextColor': '#fff', 'primaryBorderColor': '#3CB540', 'lineColor': '#3CB540', 'mainBkg': '#18794E', 'nodeBorder': '#3CB540', 'clusterBkg': 'transparent', 'clusterBorder': '#3CB540', 'titleColor': '#3CB540', 'edgeLabelBackground': 'transparent', 'textColor': '#3CB540', 'nodeTextColor': '#fff'}}}%% graph LR BM[BondingManager] -->|"checkpoint"| BV[BondingVotes] D[Delegator] -->|"castVote()"| LG[LivepeerGovernor] BV -->|"voting power"| LG LG -->|"queue"| T[Treasury / Timelock] T -->|"execute"| GOV[Governor] GOV -->|"update contracts"| C[Controller] MINT[Minter] -.->|"trustedTransferTokens()"| T ``` *** #### **BondingVotes** Arbitrum One BondingVotes implements the ERC-5805 votes interface, storing per-round stake checkpoints for every Delegator and Orchestrator. The LivepeerGovernor queries it to determine voting power at proposal creation time. Checkpoints are written automatically by BondingManager on every bond, unbond, reward, and earnings claim. } title="BondingVotes" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved · Target V2* **Purpose**: * Stores per-round stake checkpoints for every participant * Implements ERC-5805 (`getPastVotes`, `getPastTotalSupply`) used by LivepeerGovernor * Checkpoints are written by BondingManager – not called directly by users * Supports Delegator vote overrides: a Delegator can override their Orchestrator's vote **Key functions** (from `BondingVotes.sol`, `delta` branch): Called by BondingManager to checkpoint stake state; not callable directly by users Checkpoint total active stake; called by BondingManager Returns voting power for an account at the start of a given round Returns total voting power (active stake) at a given round Returns whether an account has any checkpointed stake **Contract** } filename="BondingVotes.sol" /> #### **Governor** Arbitrum One The original upgrade execution contract.

Voting power equals bonded LPT as recorded by BondingVotes at proposal creation time. Supports GovernorCountingOverridable – Delegators can override their Orchestrator's vote on any proposal. } title="LivepeerGovernor" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active · Proxy target resolved* **Purpose**: * On-chain voting for protocol proposals, weighted by bonded LPT stake * Delegators can override their Orchestrator's vote (GovernorCountingOverridable) * Passed proposals execute through the Treasury timelock, then through the Governor to the Controller * `bumpGovernorVotesTokenAddress()` must be called if BondingVotes address ever changes **Key functions** (from `LivepeerGovernor.sol`, `delta` branch): One-time initialisation via proxy Submit a new governance proposal; returns proposalId Cast a vote (0=Against, 1=For, 2=Abstain) Vote with explanation Queue a passed proposal into the timelock Execute a queued proposal after timelock delay Returns `MathUtils.PERC_DIVISOR` (the quorum denominator) Update the internal BondingVotes reference if its address has changed **Contract** } filename="LivepeerGovernor.sol" /> #### **Treasury** Arbitrum One An [OpenZeppelin](https://docs.openzeppelin.com/contracts/5.x/api/governance#TimelockController) TimelockControllerUpgradeable that holds the protocol's on-chain treasury. A configurable percentage of each round's inflationary LPT rewards is directed here by the Minter. All disbursements require a passed LivepeerGovernor proposal. Automatic contributions halt when the treasury balance exceeds `treasuryBalanceCeiling` (configured in BondingManager). } title="Treasury" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Active* **Purpose**: * Receives a fraction of each round's inflationary LPT rewards (rate set by `treasuryRewardCutRate` in BondingManager) * Governed entirely by LivepeerGovernor – all disbursements require a passed proposal * Implements TimelockController – all operations have a mandatory delay between queue and execution * Contributions automatically halt when LPT balance exceeds `treasuryBalanceCeiling` * Funds Special Purpose Entities (SPEs) and ecosystem grants via governance proposals **Key functions** ([OpenZeppelin](https://docs.openzeppelin.com/contracts/5.x/api/governance#TimelockController)) TimelockControllerUpgradeable): Schedule an operation; callable by proposer role (LivepeerGovernor) Execute a ready operation; callable by executor role Cancel a pending operation; callable by canceller role Check if an operation exists Check if an operation is past its delay and ready to execute Returns the minimum delay for all operations **Contract** } filename="Treasury.sol" /> ## Migration Contracts The [Confluence upgrade (2022)](https://medium.com/livepeer-blog/the-confluence-upgrade-is-live-3b6b342ea71e) migrated the Livepeer Protocol from Ethereum Mainnet to Arbitrum One. These contracts facilitated that migration.
The migration is complete - no new migrations are possible - but both contracts remain registered in the Controller. L2Migrator continues to process pending `claimStake` calls from participants who have not yet claimed their migrated stake as of March 2026. #### **L2Migrator** Arbitrum One Facilitated the migration of bonded stake and delegations from Ethereum Mainnet to Arbitrum One during the Confluence upgrade. Participants who migrated on L1 claim their Arbitrum-side stake by calling `claimStake()` here. The contract still holds residual ETH and continues to receive `claimStake` calls from participants who have not yet claimed. } title="L2Migrator" />}> **Proxy Address (Arbitrum One)**: **Current Target (Arbitrum One)**: *Verified · Controller registered · Migration · Proxy target resolved* **Purpose**: * Receives cross-chain migration messages from the L1Migrator via the Arbitrum bridge * Allows participants to claim their migrated bonded stake on Arbitrum One via `claimStake()` * Allows Delegators to claim migrated delegations via `claimDelegatorStake()` * Holds residual ETH from migration fee payments; no new migrations are possible **Key functions**: Claim migrated stake on Arbitrum One; callable by participants who completed an L1 migration Finalise a Delegator migration initiated on L1; called via the bridge #### **MerkleSnapshot** Arbitrum One Stores Merkle roots used to verify stake snapshots taken at the time of the Confluence migration. Used internally by L2Migrator to validate migration claims. } title="MerkleSnapshot" />}> **Address (Arbitrum One)**: *Verified · Controller registered · Migration* **Purpose**: * Stores Merkle root snapshots (keyed by snapshot ID) set at migration time * Provides `verify()` for L2Migrator to validate that a claimed stake amount was included in the original snapshot * Read-only in practice; `setSnapshot()` is callable only by the Controller owner and has not been called since the migration **Key functions** (from `MerkleSnapshot.sol`): Verify a Merkle proof against a stored snapshot root Store a Merkle root for a given snapshot ID; callable by Controller owner only **Contract** } filename="MerkleSnapshot.sol" /> ## Full Address Reference For the complete list of all current, paused, migration-residual, legacy-operational, and historical contract addresses across Arbitrum One and Ethereum Mainnet, see the [Contract Addresses](/v2/about/resources/reference/livepeer-contract-addresses) reference page.
