2026Trustless USDC bounties for Solana trading volume.
Overview
A sponsor locks USDC in escrow against a trader’s wallet. The trader is paid on-chain once the volume and hold targets are met, and the sponsor is refunded if they are not.
What I built
- Anchor program for USDC escrow, the deal lifecycle and crank-based finalization
- Swap tracking on Helius webhooks, with volume cached in Redis
- Next.js app on Postgres, plus a Telegram bot for live deal alerts
