# Treasury

## Overview

The AVS Treasury contract manages the reward funds for an AVS. It supports both ETH and ERC20-based treasuries, enforces protocol-level fees, handles secure deposits and withdrawals. 

* Depending on which chain rewards are configured, either `L1AvsTreasury` or `L2AvsTreasury` contract is deployed.

#### completeTokenReplacement

Finalizes the token replacement previously scheduled via `queueTokenReplacement`.&#x20;

#### setTokenReplacementModificationDelay
