| SortedOracles supports flagging two tokens as "equivalent". This is example do that no new oracle has to be deployed and useful for fiat-backed stablecoins. [Here is an exampl](https://github.com/celo-org/governance/pull/419/files#diff-ba5ba5397b269ceb4b93f3876bedabac605daeec083a364a270675242fe7c424)e of this approach. Using this approach, it is not needed to submit to proposals and can be done in only one. |

| Before submitting the second proposal, at least one of the oracle addresses need to call `report(address token, uint256 value, address lesserKey, address greaterKey)`. This will make a price available to the protocol for gas pricing. | ||

|
||
| ### Enabling as Gas Token | ||
|
|
||
| The second proposal enables the gas token by calling `addToken(address tokenAddress)`. After this proposal passes, EOAs should be able to pay for gas in the enabled token. | ||
| The second proposal enables the gas token by calling `FeeCurrencyDirectory.setCurrencyConfig(address token, address oracle, uint256 intrinsicGas)`. `intrinsicGas` is the estimated average amount of gas used by the functions `creditGasFees(...)`and `debitGasFees(...)`. A benchmark is recommended as an attachment to the governance proposal. |
