supported chains
Manta Bridge supports routes that move assets between a source chain and Manta Pacific. Always verify the current chain list in the official bridge interface before sending funds, because available routes can change by asset, direction, maintenance status, and liquidity.
How to Read the Chain List
The supported chain list answers two separate questions:
Where can the transfer start? This is the source chain selected in the bridge flow.
Where will the asset arrive? For Manta Bridge deposits, the destination is Manta Pacific. For withdrawals, the source is Manta Pacific and the destination is the supported return chain.
Do not assume that every asset is available on every supported chain. Chain support and asset support are related but separate. After confirming the chain route, also check the current token list in Supported Assets.
Chain Categories
Ethereum L1
Common source for deposits to Manta Pacific and destination for withdrawals back to L1.
Confirm the selected route, wallet network, asset, amount, and Ethereum gas estimate before signing.
Manta Pacific L2
Destination for deposits and source chain for withdrawals. ETH is used for gas on Manta Pacific.
Confirm your wallet is on Manta Pacific when viewing received balances or starting a withdrawal.
Other supported EVM chains, if listed
Some bridge interfaces may expose additional EVM-compatible source or destination routes when available.
Treat availability as route-specific. Verify the chain, token contract, bridge path, and wallet prompt in the live interface.
Test networks, if listed
May be available for development or testing flows, depending on the bridge environment.
Do not send mainnet assets to a testnet route. Confirm whether the interface is mainnet or testnet before using it.
Deposits and Withdrawals
Deposits move assets from a supported source chain to Manta Pacific. The source-chain transaction pays gas on the source chain, and the received asset appears on Manta Pacific after the bridge message is processed.
Withdrawals move assets from Manta Pacific back to a supported destination chain. Because Manta Pacific follows an optimistic-rollup-style exit model, withdrawals may involve multiple steps and require finalization on the destination side. Ethereum's overview of optimistic rollups explains the general L2 exit model.
A visible chain in a wallet does not mean that route is supported by the bridge. Use the bridge interface as the source of truth for current source chains, destination chains, and route status.
Manta Pacific as the Destination
Manta Pacific is a modular Ethereum L2 built with OP Stack execution and Celestia data availability. The OP Stack provides the L2 execution framework, while Celestia provides a dedicated layer for data availability. For technical background, see the OP Stack documentation and Celestia's guide to data availability.
When bridging to Manta Pacific:
Select a supported source chain.
Select Manta Pacific as the destination.
Choose an asset supported on that route.
Review the route details, fees, and wallet prompts.
After completion, switch the wallet to Manta Pacific to view and use the asset.
Before You Bridge
Confirm these details every time:
Source and destination chains
Prevents sending from or to the wrong network.
Asset availability
Not every supported chain supports every token.
Wallet network
The transaction must be signed on the network where the action starts.
Gas token balance
You need the source chain's gas token to submit the transaction, and ETH on Manta Pacific for later L2 activity.
Live route status
Routes can be paused, changed, or unavailable for a specific asset or direction.
