# README

> 🌉 [**Open the Manta Bridge app →**](https://mantabridge.cc/) Bridge ETH and USDC to Manta Pacific in a few clicks. New here? Start with [What is Manta Bridge?](/manta-bridge-docs/what-is-manta-bridge.md)

Manta Bridge moves assets such as ETH and supported ERC-20 tokens between Ethereum and Manta Pacific. These docs explain the bridge flow, what to check before you transfer, and how deposits and withdrawals work.

Use the [Manta Bridge](https://mantabridge.cc/) to review supported assets, networks, fees, and live transaction details before submitting a transfer.

## Start Here

* [What is Manta Bridge?](/manta-bridge-docs/what-is-manta-bridge.md) - Learn what the bridge does and when to use it.
* [How it works](/manta-bridge-docs/getting-started/how-it-works.md) - Understand deposits, withdrawals, approvals, and rollup settlement at a high level.
* [Bridge ETH to Manta Pacific](/manta-bridge-docs/guides/bridge-eth-to-manta-pacific.md) - Follow the basic ETH deposit flow from Ethereum to Manta Pacific.
* [FAQ](/manta-bridge-docs/faq.md) - Find quick answers for common bridge, wallet, gas, and transaction questions.

## What These Docs Cover

Manta Bridge connects Ethereum L1 with Manta Pacific, a modular Ethereum L2 that uses OP Stack execution and Celestia data availability. ETH is the gas token on Manta Pacific, so keep enough ETH available for transactions after bridging.

These docs focus on:

## Bridge Basics

Deposits move assets from Ethereum L1 to Manta Pacific L2. After you confirm the transaction in your wallet, the bridge submits the transfer through the relevant contracts and the asset becomes available on Manta Pacific when processing completes.

Withdrawals move assets from Manta Pacific back to Ethereum L1. Because Manta Pacific follows a rollup exit model, withdrawals are not the same as normal wallet-to-wallet transfers. Review the live bridge interface for the current withdrawal status, required actions, and any network-specific timing.

ERC-20 transfers require token approval before the bridge can move the selected token. Approval is a separate wallet transaction from the bridge transfer itself. For background on token approvals and fungible token behavior, see Ethereum's [ERC-20 token standard](https://ethereum.org/developers/docs/standards/tokens/erc-20/).

## Network Model

Manta Pacific is built as an Ethereum L2. Rollups process transactions offchain and use Ethereum as part of their settlement model; Ethereum's overview of [optimistic rollups](https://ethereum.org/developers/docs/scaling/optimistic-rollups/) explains the general mechanism.

Manta Pacific also uses modular infrastructure. For technical background, see the OP Stack [protocol documentation](https://docs.optimism.io/op-stack/protocol/getting-started) and Celestia's explanation of [data availability](https://docs.celestia.org/learn/celestia-101/data-availability/).

{% hint style="info" %}
Fees, supported assets, transaction status, and withdrawal requirements can change with network conditions and bridge configuration. Always verify live values in the bridge interface before confirming a transaction.

## Next Steps

If you are new to the bridge, start with [What is Manta Bridge?](/manta-bridge-docs/what-is-manta-bridge.md), then read [How it works](/manta-bridge-docs/getting-started/how-it-works.md). When you are ready to make a transfer, follow the [ETH bridging guide](/manta-bridge-docs/guides/bridge-eth-to-manta-pacific.md) and keep the [FAQ](/manta-bridge-docs/faq.md) open for troubleshooting.
