# Contract addresses

> The Livepeer protocol contracts orchestrators and delegators interact with, and how to verify any address on-chain.

Livepeer protocol contracts are deployed on **Arbitrum One** (active) and **Ethereum Mainnet** (legacy
bridge and governance). Most use a proxy/target pattern: the **proxy** address is stable across
governance upgrades, while the target changes when a new implementation is deployed.

<Warning>
  **Always verify an address on-chain before using it.** Confirm you are on the official
  `docs.livepeer.org` site, and cross-check against the on-chain Controller (below) and a block
  explorer. An address with no label, unverified bytecode, or zero transactions is **not** a Livepeer
  contract.
</Warning>

## Deployed addresses (Arbitrum One)

Resolved from the on-chain **Controller** (`getContract(keccak256(name))`) — **last verified
30 July 2026**. These are the stable proxy addresses.

These Arbitrum One contracts are **not** registered in the Controller. Addresses come from Livepeer's
own deployment artifacts ([livepeer/protocol](https://github.com/livepeer/protocol/tree/confluence/deployments/arbitrumMainnet),
[livepeer/arbitrum-lpt-bridge](https://github.com/livepeer/arbitrum-lpt-bridge/tree/main/deployments)),

<Note>
  **Historical:** before the 2022 Confluence migration the protocol ran on Ethereum mainnet; those
  contracts remain deployed but are **permanently paused** — if you find an old mainnet
  `BondingManager` or staking link, it is not the live protocol. All protocol activity is on
  Arbitrum One. Migration-era and genesis-era contracts are cataloged in the
  [protocol repo](https://github.com/livepeer/protocol).
</Note>

## Verify against the on-chain Controller

Every Arbitrum One protocol address is registered in the **Controller** at
`0xD8E8328501E9645d16Cf49539efC04f734606ee4` (chain 42161). Query it directly — no trust in docs
required:

```bash theme={"theme":{"light":"github-light","dark":"dark-plus"}}
# Example: resolve the BondingManager proxy address
cast call 0xD8E8328501E9645d16Cf49539efC04f734606ee4 \
  "getContract(bytes32)(address)" \
  $(cast keccak "BondingManager") \
  --rpc-url https://arb1.arbitrum.io/rpc
```

A registered contract returns a non-zero address. `0x000…000` means the name is misspelled or not on
this chain. Then cross-check the returned address on
[Arbiscan](https://arbiscan.io/accounts/label/livepeer) or
[Blockscout](https://arbitrum.blockscout.com): it should carry a `Livepeer:` label and verified
source.
