feat: liquidity mining update

[ncitron]

To test, run npm run test-update-proposal.

This is just about ready. The only thing missing currently is the correct emissions values. One thing I noticed that was strange is that aBUSD does not have a scaledTotalSuopply. Is this just because it is using an older version of the contracts? Is it safe to upgrade BUSD's aToken and variabelDebtToken implementation to the most recent version?

Hello @ncitron, yes BUSD aToken and debt tokens are still not updated to the latest AToken or Debt token revisions. The update of incentives or the needed update of the AToken version or the Debt tokens can only be performed via Governance proposal and voted by the Aave community. You could propose to update those tokens and the incentives at the same proposal at the community forum.

Yep, that's the current plan. ARC is linked here: https://governance.aave.com/t/arc-aave-v2-liquidity-mining-program-90-days-at-30-reduced-rate/5946

Also should I take the gas refund from the ecosystem reserved @ernesto-usal?

[eboadom]

@ncitron if deploying the aToken/debtToken, definitely I think it is a good idea to transfer some AAVE to compensate the deployment cost, describing it on the text of the proposal

[ncitron]

Yep! I've added a 70 AAVE transfer from the eco reserver to one of our wallets which should be more than enough to cover gas. I have also added it to the proposal text.
