Implementing a recovery function for exported ERC20 tokens in the Curves smart contract is critical for maintaining the integrity of its ecosystem, where the ERC20 token supply must precisely mirror the value locked within the protocol, as highlighted by the protocol in the readme section: 
For any token associated with Curves, its imperative that the total ERC20 supply remains exactly equivalent to the value locked within the Curves protocol. This one-to-one correspondence ensures consistency and integrity between the ERC20 tokens in circulation and the underlying assets within the Curves ecosystem.
This function addresses the risk of accidental token deposits, ensuring the protocols balance and consistency. It necessitates strict access control, comprehensive testing, and transparency to maintain user trust and prevent unauthorized access. This feature not only acts as a safeguard against user errors but also reinforces the reliability and stability of the Curves protocol, ensuring that the total ERC20 supply accurately reflects the underlying assets, thus upholding the ecosystems integrity and trustworthiness.
Heres a suggested fix that will have a side benefit of retrieving any other non-exported ERC20 tokens if need be:
