# Bridge LPT between Ethereum and Arbitrum

> Move or acquire LPT on Arbitrum One so it can be delegated through the Livepeer protocol.

> [!WARNING]
>
> This page applies only to unbonded LPT. If your LPT is already bonded, unbond it and wait through the protocol unbonding period before you try to bridge or withdraw it.

> [!TIP]
>
> You always need ETH on the chain where you are signing transactions. For a canonical bridge deposit, that means Ethereum mainnet gas first and then a small Arbitrum balance for later delegation actions.

## What counts as "ready to delegate"

Your LPT is ready once all of these are true:

* the token is in a self-custody wallet on **Arbitrum One**
* you have a small ETH balance on **Arbitrum One** for future protocol transactions
* the wallet is one you can connect to [Livepeer Explorer](https://explorer.livepeer.org)

The canonical trust-minimised route is the official Arbitrum bridge. Exchange withdrawals and DEX swaps can also get you to the same end state, but they introduce exchange or liquidity-pool risk and change over time.

## Canonical bridge route: Ethereum mainnet to Arbitrum One

Use this path if you already hold LPT on Ethereum mainnet and want the protocol-native bridge flow.

### 1. Open the official Arbitrum bridge on Ethereum mainnet

Go to [bridge.arbitrum.io](https://bridge.arbitrum.io/) and connect the wallet that currently holds your Ethereum-mainnet LPT.

### 1. Select LPT as the token

Search for `LPT`. If the token selector does not surface it, paste the Ethereum-mainnet token address directly: `{lptL1}`.

### 1. Set Arbitrum One as the destination and approve

Confirm the destination network is **Arbitrum One**, enter the amount, and sign the approval transaction when prompted.

### 1. Confirm the bridge deposit

Sign the deposit transaction. The bridge locks mainnet LPT and mints the Arbitrum-side representation. Track the transfer in the bridge UI or on the [retryable dashboard](https://retryable-dashboard.arbitrum.io/).

### 1. Verify Arbitrum receipt before delegating

Confirm the Arbitrum wallet now holds LPT at `{lptL2}`. You are ready for the Livepeer Explorer once the tokens are visible on Arbitrum One.

## Other practical routes

### Buy or withdraw directly to Arbitrum One

If you are acquiring LPT on an exchange, the fastest route is often a direct withdrawal to Arbitrum One. Do not rely on any static exchange-support list here; verify the exchange's current network selector at the moment you withdraw.

### Swap on Arbitrum One

If you are already on Arbitrum One with ETH, WETH, or stablecoins, swapping into LPT can be simpler than bridging LPT itself. The key requirement is still the same: after the swap, the LPT must be in your own Arbitrum wallet.

## Bridge-specific details worth knowing

> [accordion] Why third-party bridges are risky for LPT
>
> LPT uses dedicated bridge contracts rather than the generic ERC-20 gateway flow. If a third-party bridge does not explicitly support LPT's route, do not assume it is safe.

> [accordion] The contracts involved
>
> Canonical bridge flows touch the mainnet `L1Escrow` contract at `{l1Escrow}` and the Arbitrum `L2LPTGateway` contract at `{l2Gateway}`.

> [accordion] What you cannot bridge
>
> Bonded LPT cannot be bridged. Unbond and withdraw first.
