Bridge to Scroll

Arriving and leaving are not the same trip

Coming in from Ethereum through Scroll’s own bridge, the deposit is picked up on the Scroll side by the network itself — you send once and wait. Going back out is a different process: the batch holding your withdrawal has to be finalized on Ethereum first, and only then can an Execute Withdrawal transaction, sent by you or a third-party service with a proof, release the funds there (Scroll documentation, withdraw gateways). It is a second transaction, on a second network, after a wait you do not control. Third-party providers price that difference differently, which is part of why their quotes spread.

Gas is paid in ETH, twice over

Every transaction on Scroll pays in ETH, and the fee has two parts: execution on Scroll itself, and the cost of publishing the data to Ethereum (Scroll documentation). The second part follows activity on Ethereum rather than on Scroll, so the cost of the same transfer moves even when Scroll is quiet. A stablecoin arriving on its own cannot be sent onward without a little ETH beside it.

How many sources answered

Support for Scroll is decided by each provider and can differ by token and by the network you start from. The Quote sources column shows how many answered for your route; where fewer than two confirm, we do not present it as a comparison. If an exchange we track lists Scroll for the token, its published withdrawal fee appears beside the bridges with the date we checked it — and when none does, there is simply no exchange row.
