Fast withdrawals

Fast withdrawals allow you as a chain operator, to upgrade the deployed contracts and allow you to modularize the security around withdrawals. This logic is fully configurable, so security can be increased, decreased or altered as your chain sees fit.

Hyperlane integration

Hyperlane is Superbridge's provider of choice for modularizing the withdrawal flow.

With Hyperlane's relayer network withdrawals become a one transaction operation (instead of the usual three of OP stack chains), greatly improving the user experience around token withdrawals.

In addition to only requiring one transaction, Hyperlane's concept of Interchain Security Modules (ISM's) allow for many different options to secure the integrity of these withdrawal messages.
