How It Works (YLA):
YLA is relatively much more complex to join or exit since Yearn v1 Vaults don’t have external markets or liquidity pairs. Currently, YLA is the main liquidity pair for them. Therefore, USDC deposits and withdrawals require USDC to be deposited in five Curve Pools, then deposit these LP tokens in Yearn vaults, and after that deposit these five LP tokens into YLA. This process involves more than 20 transactions in total, counting approvals, and ~$800 in gas costs. Sounds crazy, right?
