EOL Vault (miAsset)

First, familiarize yourself with the EOL Vault concept in EOL Vault (miAsset).

The EOL Vault implements ERC4626 interfaces. Each EOL vault corresponds to a specific hub asset. For example, miETH (EOL vault) corresponds to ETH (hub asset).

You can expect standard ERC4626 functionality, with the exception of the withdraw and redeem functions.
Instead of using the withdraw and redeem functions of the EOL Vault, use the Opt-out Queue. For more details on the Opt-out Queue, refer to Opt-out.

It's worth noting that in most cases you might not need to integrate with the opt-out queue at the contract level.
