feature request: flash allowances #263
Description
Flash allowances allow smart wallets to interact with external applications inexpensively, without hanging approvals and without the need for MetaTransactions.
A new Permit2 deployment would include this new functionality, where integrators can choose to use the new contract when needed. The new Permit2 version is backward compatible with the existing one.
A Proof of Concept (POC) is proposed in the following PR: #262
