Mantle Bridge is the official bridge for the Mantle network. It allows users to transfer tokens — including MNT and ETH — between Ethereum mainnet and Mantle Layer 2. Transactions are secured by Mantle's optimistic rollup infrastructure, ensuring fast finality and low fees.
Mantle Bridge supports MNT (Mantle's native token), ETH, and a growing list of ERC-20 tokens. The interface always shows available assets based on your connected wallet balance. New tokens are added as Mantle ecosystem expands.
Deposits from Ethereum to Mantle typically confirm within a few minutes after the Ethereum transaction is finalized. Withdrawals from Mantle back to Ethereum require a 7-day challenge period as part of the optimistic rollup security model. You can track all pending transactions in the History tab.
You need an EVM-compatible wallet to use Mantle Bridge. MetaMask, WalletConnect-compatible wallets, Coinbase Wallet, and most browser-based Web3 wallets are supported. Simply click "Connect Wallet" to get started.
Bridging via Mantle Bridge does not charge additional protocol fees. However, standard Ethereum gas fees apply when initiating transactions on L1. On the Mantle side, gas costs are significantly lower thanks to Mantle's L2 architecture. You can get gas for Mantle using the "Get Gas" button.
