How long do transfers to/from Ethereum take?
The transfer from Ethereum usually takes <10 minutes.
The transfer to Ethereum takes up to 8 hours in normal bridge transfer while it takes just few minutes in Fast Rainbow Bridge.
Transfers to Ethereum take longer in normal transfer because of the confirmation times on the Ethereum blockchain. The blocks are being synced across to an ETH Light Client that lives in the NEAR smart contract.
Faster bridge transfers have been released now which would take few minutes to transfer to Ethereum.
