Smart Orders

When signing with EIP-1271, it’s possible for a contract to dynamically change validity over time, based on arbitrary conditions. This allows for creating more complicated “smart orders”, as pioneered by Cowswap (opens in a new tab).

Normally, Memswap will cache the signature check to save gas, which interferes with such functionality. In order to enable it, set isSmartOrder=true and the caching will be skipped.
