sCIP#28 - cyDAI/cyUSDC/cyUSDT

Summary:

Proposing to add a new pool cyDAI/cyUSDC/cyUSDT. This is yearn x cream Iron Bank. This proposal is not to add a gauge or burner, simply to add the swap pool. The pool has already been developed and requires no additional man hours from the core Curve team.

Abstract:

PR available for review. This is an adaptation of the y pool template to accommodate compound style c-tokens. This same format can be used for compound, cream, yearn, etc.

Motivation:

More pools allow for deeper liquidity, better trades, and greater arbitrage between pools. cy*tokens are currently idle DAI, USDC, USDT (and sUSD) that can be used for further trade depth, volume, and liquidity.

Specification:

cyDAI, cyUSDC, cyUSDT
