[ABIP-01] Add MTA & Stake it for the Ethereum Treasury

Summary: Allow the treasury to allocate up to 1% of its assets into purchasing and staking MTA. This will increase our yields on Stable Coins in mStable pools. ($25,000)

Abstract: Abachi would like to stake the recently acquired MTA in the mstable V2 staking contract. This will yield both more MTA as rewards and allow Abachi to have a governing voice in mStable. Abachi is acquiring MTA to be able to divert the emissions controller to the pools it favors which increase yields for the 50% stables it keeps in its treasury.

The stables are divided into multiple treasuries on Ethereum and Polygon Gnosis wallets. For this Abachi is working with mStable team to whitelist the gnosis address and allow staking.

Both Abachi and mStable will also issue a press release on their blogs announcing this.

Once this is done, Abachi will open a new proposal for both parties to introduce mUSD as the primary stable to use. This proposal will be posted later when all the mechanics have been worked out.

Motivation: Team wants to only keep yield producing assets in its treasury. Since 50% of the treasury is at all times in stables, the governance and policy need to ensure this is producing yields. Abachi has moved 1m of its treasury into these pools across polygon and ethereum and is currently earning a yield of 10-15% paid in USD and MTA.

The team strongly believes in a time of CRV wars the mStable platform is a dark horse.

Pros:

• Increase yields on a highly audited and reputed platform.
• Ability to gain a strong voice in mStable governance.
• Increase yields on stable pools and possibly divert the emission controller in the future to pay yields for an mUSD-ABI LP.
• Increases treasury $ value as MTA being held increases.
• Joint marketing and partnerships

Cons:

• As with all systems there is a smart contract risk, or that one of the underlying assets in the mStable basket loses peg. In this case mStable has a slashing mechanism in place.
• The price of mStable keeps dropping. Currently its near its all time lows. The initial purchase is however only $25000

NOTE: Abachi and mStable are currently working on a joint press release regarding this and the mstable team will also be voting on this in their own governance. In case the vote fails on either side, we will unwind our MTA position.
