Canonical bridge

Scroll Bridge

The official bridge between Ethereum and Scroll, a ZK rollup. Deposits usually arrive within 15 to 20 minutes; withdrawals to Ethereum take a few hours and need a claim on Ethereum.

How it works

1You open the bridge on the Scroll site, pick the token and the direction, and confirm the transaction.
2Deposits are picked up from Ethereum and credited on Scroll.
3Withdrawals are batched, and a zero-knowledge proof of the batch is verified on Ethereum. After that you claim the funds on Ethereum with a separate transaction.

Trust model

Withdrawals are released only after Ethereum verifies a validity proof, so no group of signers controls the funds. You rely on Scroll's proof system and contracts, which the Scroll team can still upgrade.

Strengths

Official route secured by validity proofs.
No week-long challenge period.
No fee beyond network gas.

Limitations

Withdrawals take hours and require a manual claim that costs Ethereum gas.
Slower than liquidity bridges for both directions.
Connects only Ethereum and Scroll.
