@petrovska-petro, I took the liberty of merging main and changing payments multisig to the new one.

Just wanted to note that the operation will not result in a balance state for stables. This is acceptable as discussed during the Treasury call as the stables balancing and yearly runway coverage are goals to be achieved by the end of each quarter, as per policy. Here is some napkin math on the expect final state:

• Selling 1,154,912 DAI for 1154948.396852 USDC leaves 34555.62 DAI

With the LUSD sold for USDC, we obtain an additional 682526.398697 USDC.

So, after the trades we will have: 95,651.0265+1154948.396852+682526.398697 = 1,933125.82205 USDC

After the transfers, the USDC amount will be reduced to: 1933125.82205 - (2927.77*5 + 300000 + 1154918) = 463568.97205 USDC

Therefore, the final state will be:

• 34555.62 DAI
• 584,807.4172 USDT
• 463568.97205 USDC
• 0 LUSD

Swapping ~half of USDT for DAI would do the trick, as previously suggested but it might make sense to wait until a decision around extending the stable runway is made.

Review

• Performs the swaps described above - LGTM
• In a separate script, it:
  • Transfers BADGER and USDC q1 Budget to new Assc. Payments Multisig
  • Deposits 300K BADGER on Llamapay contract
  • Transfers make up amount to Treasury Council members
• Addresses LGTM

@petrovska-petro, I took the liberty of pushing a simulation, assertions and snaphots that I added while reviewing locally. You will find that core logic was left intact, these just add extra sanity and qa.
