# Manta Bridge Docs

**Manta Bridge is the native bridge that moves ETH and ERC-20 tokens between Ethereum L1 and Manta Pacific — an Ethereum Layer-2 built on the OP Stack with Celestia for data availability.** It is non-custodial: you bridge directly from your own wallet and assets settle on-chain. The official interface is the [Manta Bridge](https://mantabridge.app/).

## What Is Manta Bridge, and Is It Official or Third-Party?

Manta Bridge is the **canonical, official** bridge for Manta Pacific — the trust-minimized path that locks assets on Ethereum and mints their canonical representation on Manta Pacific. Third-party routes (Orbiter, Owlto, Relay, Layerswap, Rhino, Oku) are faster and often cheaper for small transfers but add the bridge provider's trust assumptions.

## How Do You Bridge to Manta Pacific?

To bridge, connect your wallet to Manta Bridge, select ETH or a supported ERC-20, confirm the L1 transaction, and the funds arrive on Manta Pacific within minutes. Add the network first, then use the funds in Manta Pacific apps.

## How Much Does Manta Bridge Cost, and How Long Does It Take?

Deposits to Manta Pacific take a few minutes and are cheap relative to L1 activity; the cost is dominated by the Ethereum L1 gas required to submit the deposit. Withdrawals back to Ethereum take longer because they follow OP Stack exit mechanics. When the interface shows a high fee, that figure is the L1 gas component, not a Manta charge.

Guides: [cost](https://mantabridge.app//manta-bridge-cost/) · [how long it takes](https://mantabridge.app//how-long-does-manta-bridge-take/) · [why gas fees show as high](https://mantabridge.app//why-manta-bridge-says-ethereum-gas-fees-are-high/) · [when it's cheaper than third-party routes](https://mantabridge.app//when-is-manta-bridge-cheaper-than-third-party-routes/).

## How Do Withdrawals From Manta Pacific to Ethereum Work?

Standard withdrawals from Manta Pacific follow the OP Stack optimistic-exit flow: initiate on L2, then prove and finalize the withdrawal on L1 after the challenge period. Manta Pacific's fast-finality path is designed to shorten that wait. A pending withdrawal is not stuck — it is progressing through the exit steps.

## What Is Manta Pacific's Architecture (OP Stack + Celestia)?

Manta Pacific executes as an OP Stack rollup and posts its data to Celestia for data availability, which lowers costs versus posting DA to Ethereum. Its security therefore rests on OP Stack fault-proof assumptions plus Celestia DA and the sequencer's force-inclusion guarantees. OP Stack mechanics are documented in the [Optimism docs](https://docs.optimism.io/), Celestia's role in the [Celestia docs](https://docs.celestia.org/).

Guides: [is it still OP Stack + Celestia](https://mantabridge.app//is-manta-pacific-still-op-stack-and-celestia/) · [Celestia DA](https://mantabridge.app//celestia-data-availability-manta-pacific-bridge/) · [sequencer & force-transaction trust](https://mantabridge.app//manta-pacific-sequencer-force-transaction-trust-assumptions/).

## Is Manta Bridge Safe?

Manta Bridge is the canonical bridge and inherits Manta Pacific's OP Stack security and Celestia data-availability model; the main user risks are phishing look-alike sites and unverified tokens, not the native contracts. Always verify contract addresses and cross-check independent risk analysis on [L2BEAT](https://l2beat.com/scaling/projects/manta-pacific).

## What Happened to Manta Atlantic?

Manta previously operated Manta Atlantic (a separate chain) alongside Manta Pacific, and users migrated assets from Atlantic to Pacific. If you still hold assets on Atlantic, follow the migration path before assuming a route is closed.

## Contracts & Developer Integration

Before interacting programmatically, verify the deployed bridge contracts and use the official SDK rather than hard-coding addresses. Developers can bridge ETH and ERC-20 via the SDK and submit new tokens for native-bridge support.

Guides: [contract addresses](https://mantabridge.app//manta-bridge-contract-addresses/) · [JS SDK for ETH & ERC-20](https://mantabridge.app//manta-bridge-js-sdk-eth-erc20/) · [list an ERC-20 on the native bridge](https://mantabridge.app//list-erc20-on-manta-native-bridge/).

## Manta Bridge vs Third-Party Routes

| Route                                                      | Withdrawal speed                       | Cost (small transfer) | Trust model                |
| ---------------------------------------------------------- | -------------------------------------- | --------------------- | -------------------------- |
| Native Manta Bridge                                        | Slower — OP Stack exit + fast-finality | Higher (L1 gas)       | Canonical, trust-minimized |
| Third-party (Orbiter, Owlto, Relay, Layerswap, Rhino, Oku) | Fast — minutes                         | Often cheaper         | Adds bridge-provider trust |

Use the native bridge for canonical assets and larger, trust-sensitive transfers; a third-party route can win on speed and cost for small moves.
