focused on order lifecycle issues: ghost fills, stale signatures, cancel race conditions, and backtest/prod execution divergence.
Real-time observability for Polymarket market makers
Verifies every CLOB fill against on-chain OrderFilled events. Webhook-based, language-agnostic.

Building on-chain system across EVM, Solana, and Move chains.
Deep work on Polymarket internals: Builder Relayer architecture, CTF V1 → V2 migration, EIP-1271 signature validation, WS subscription field-presence format, feeRateBps / order payload structure, proxy vs EOA redemption.
Go · Solidity · Rust · Move · TypeScript If you're running a Polymarket MM bot and seeing any of:
- Cancel requests returning 200 but orders still filling Backtest / production divergence order can't be found — already canceled or matched but size_matched = 0 WS cancellation events not arriving Unexplained "mystery fills" eating PnL
I've been tracking engine-side regression across ~15 maker wallets and have p99 latency data + stale-signature event counts. Happy to compare notes. Reach out
