Swap between Yearn Vaults V2

Yearn V2 Vaults Swap

Yearn V2 Vaults Swap is a collection of smart contracts to simplify Yearn V2 Vaults swap (or migration from v2 or v1).

How it works

It simplifies the swap between Yearn V2 Vaults with the same token (underlying).

It supports migration from v1 to v2 too!

It supports permit to allow 1-tx operations (only from v2 to v2).

Usage

You have the following methods available:

• swap(address vaultFrom, address vaultTo), swap full balance from vaultFrom to vaultTo. Requires approve tx.
• swap(address vaultFrom, address vaultTo, uint256 deadline, bytes calldata signature), like the previous but using permit (v2 to v2 only).
• swap(address vaultFrom, address vaultTo, uint256 shares), swap a specific amount of shares from vaultFrom to vaultTo. Requires approve tx.
• swap(address vaultFrom, address vaultTo, uint256 shares, uint256 deadline, bytes calldata signature), like the previous but using permit (v2 to v2 only).

Currently, it's a developer tool, use at your own risk, no audit!
