Canonical bridge

Linea Bridge

The official bridge between Ethereum and Linea, the ZK rollup built by Consensys. Deposits take about 20 minutes; withdrawals to Ethereum take about 2 to 12 hours.

How it works

1You connect a wallet on the Linea bridge page, choose the token and the direction, and confirm the transaction.
2For deposits, the message is relayed to Linea and the funds can be credited automatically. USDC moves through Circle's CCTP instead of a wrapped token.
3For withdrawals, Linea must publish a zero-knowledge proof on Ethereum first. After that, the funds are claimed on Ethereum automatically or with one manual transaction.

Trust model

Withdrawals are accepted only after Ethereum checks a validity proof of Linea's state, so you rely on Linea's proof system and contracts rather than on a group of signers. Linea's operator can still upgrade the contracts and currently runs the only sequencer.

Strengths

Official route with no extra fee beyond network gas.
No challenge week: withdrawals finish in hours, not days.
Native USDC through CCTP, with a fast mode that takes seconds.

Limitations

Withdrawals still take hours; a liquidity bridge is faster.
A manual claim on Ethereum may be needed, which costs Ethereum gas.
Connects only Ethereum and Linea.
