…types (COW-1006)
Identifies and classifies 5 of the top 9 Unknown handler addresses:
- 0xc0fc3d (mainnet, 613 generators): Curve CowSwapBurner
- 0x995831 (mainnet, 578): Balancer v3 CowSwapFeeBurner v2
- 0x0e800d (mainnet, 30): Balancer v3 CowSwapFeeBurner v1 (deprecated)
- 0x254f3a (gnosis, 80): Balancer v3 CowSwapFeeBurner v2
- 0xb148f4 (gnosis, 110): CoW AMM ConstantProduct pool (verified)
Remaining 4 addresses stay Unknown: two unverified gnosis proxies (likely CoW AMM
but unconfirmed) and two unverified mainnet handlers from an unknown deployer.
All new types are non-deterministic. They are added to NON_DETERMINISTIC_TYPES
so C4 backfills them via /account/{owner}/orders at live-sync start.
