# Overview

The system is comprised of a set of contracts, with the main one being the vault contract (MellowSymbioticVault / MellowVaultCompat). This vault is a modification of the ERC4626 standard, featuring queued withdrawals. To handle these queued withdrawals, there is a separate contract called the SymbioticWithdrawalQueue. The code has multiple audits and is available here: <https://github.com/mellow-finance/simple-lrt>.&#x20;
