 ### Rationale
 
-This proposal builds on the rationale of [CGP 66](TBD), where the effort was to keep gas cost for cUSD at  $0.01 for a transfer paid for cUSD itself. Since then, it's been made possible to pay gas with USDC and USDT and the total cost for a tx has reduced considerably. These are gas costs of transfers of those tokens on mainnet at the time of writing:

 Please note that these numbers are illustrative, smart contracts are complex and how much gas a transfer takes may vary depending on many factors. The actual cost of gas is also volatile, affected also by the value of CELO and network usage.
