Withdraw Flow

User withdraws are processed using the Atomic Queue.

1. User should approve the atomic queue to spend their BoringVault share.

2. The user must have enough BoringVault shares to cover the amount they are trying to withdraw

3. The UI can call Accountant.getRateInQuoteSafe(ERC20 want) then apply an appropriate discount to the answer to determine the atomicPrice to use for the request.

4. The UI can call AtomicQueue.isAtomicRequestValid which returns a bool indicating whether or not the request is valid

5. The user should call AtomicQueue.updateAtomicRequest once there request is valid

💡 Withdraw requests are usually fulfilled in 1-3 days depending on the discount applied to the users shares.
