+# ERC-7540 Reference Implementations • [![CI](https://github.com/ERC4626-Alliance/ERC-7540-Reference/actions/workflows/tests.yml/badge.svg)](https://github.com/ERC4626-Alliance/ERC-7540-Reference/actions/workflows/tests.yml)
+
+Reference implementations for [ERC-7540](https://eips.ethereum.org/EIPS/eip-7540).
+
+This code is unaudited.
+
+#### Controlled Async Deposit ([code](https://github.com/ERC4626-Alliance/ERC-7540-Reference/blob/main/src/ControlledAsyncDeposit.sol))
+- Deposits are asynchronous and subject to fulfillment by an owner account
+- Redemptions are synchronous (standard ERC4626)
+
+#### Controlled Async Redeem ([code](https://github.com/ERC4626-Alliance/ERC-7540-Reference/blob/main/src/ControlledAsyncRedeem.sol))
+- Deposits are synchronous (standard ERC4626)
+- Redemptions are asynchronous and subject to fulfillment by an owner account
+
+#### Fully Async Vault ([code](https://github.com/ERC4626-Alliance/ERC-7540-Reference/blob/main/src/FullyAsyncVault.sol))
+Inherits from Controlled Async Deposit and Controlled Async Redeem
+
+- Both deposits and redemptions are asynchronous and subject to fulfillment by an owner account
+
+#### Timelocked Async Redeem ([code](https://github.com/ERC4626-Alliance/ERC-7540-Reference/blob/main/src/TimelockedAsyncRedeem.sol))
+- Deposits are synchronous (standard ERC4626)
+- Redemptions are asynchronous and subject to a 3 day delay
+- New redemptions restart the 3 day delay even if the prior redemption is claimable.
+- The redemption exchange rate is locked in immediately upon request.
