Colocation tasks before production

[cowfee]

Before Staging

✅

• Store CIP-20 data:
  • Insert data into settlement_observations (looks like a trivial bug).
  • Insert data into solver_competition (we have to build the JSON blob we store and also store that). Required Solver Competion Fields #1603 and update solver rewards script.
  • Define new shape of solver_competition and save it to db Missing CIP20 data in settlement observations table #1614
• Respect auction deadline in the solvers crate. Make DEX-Based Solvers Respect Auction Deadline #1664
• Sort orders in the driver before sending the auction to solvers:
  • Sort market orders before limit orders.
  • Sort well-priced orders before mispriced ones, using the reference prices provided in the auction. Make the sorting order randomized, weighted by how likely each order is to be settled. So more likely-to-settle orders will probably come first, and less likely-to-settle orders will come later, but the sorting order shouldn't be deterministic. Here's a reference PR which implemented this in the old code.
  • Filter orders based on user balance. If the user doesn't have enough balance to settle an order, it should be filtered out. Note that if there are multiple orders from the same user, the later orders should be filtered out if the user's balance only covers the former orders. So the filtering should be context-aware.
• Fetch 0x Limit Order Liquidity in colocated driver #1666:
  • Balancer.
    • Balancer V2 Liquidity Configuration in the Driver #1698
    • Setup Balancer V2 Liquidity Indexer #1700
    • Add Driver Support for Balancer V2 Weighted Pools #1701
    • Add Driver Support for Balancer V2 Stable Pools #1702
  • Port Swapr Liquidity to Colocated Driver #1670
• Fetch more token metadata in the driver (currently, the autopilot passes all this metadata to the driver, but in the future the driver should do this on its own):
  • Token decimals.
  • Token symbols.
  • Token balance available in the settlement contract.
• [Non blocking] Add /reveal to driver Add /reveal to driver #1744
• Score calculation Score calculation for colocated driver #1893

Before Production

• Make sure solver reward payout scripts work as expected
• Fix auto-deployment k8s-autodeploy#3
• Populate better solver competition data #1949

After Production (Cleanups)

• Cut Auctions in Autopilot run_loop #1673
• Port ZeroEx LimitOrder Liquidity
