Withdrawing Funds from Layer 2

There are two types of withdrawals: Fast Withdrawals and Slow Withdrawals:

Fast Withdrawals

Fast withdrawals utilize a withdrawal liquidity provider to send funds immediately and do not require users to wait for a Layer 2 block to be mined. Users do not need to send any Transactions to perform a fast withdrawal. Behind the scenes, the withdrawal liquidity provider will immediately send a transaction to Ethereum which, once mined, will send the user their funds. Users must pay a fee to the liquidity provider for fast withdrawals equal to the greater of the gas fee the provider must pay and 0.1% of the amount of the withdraw. Fast withdrawals are also subject to a maximum size of $200,000.

Slow Withdrawals

Slow withdrawals do not use a liquidity provider to speed the withdrawal process, and so must wait for a Layer 2 block to be mined before they are processed. Layer 2 blocks are mined roughly once every 10 hours, though this could be more or less frequent (up to 20 hours) based on network conditions. Slow withdrawals occur in two steps: first the user requests a slow withdrawal, then once the next Layer 2 block is mined the user must send a Layer 1 Ethereum transaction to claim their funds.
