Grind-Bounty Market

Hard vanity addresses are hours-to-years on one machine. Here you escrow a USDC bounty and a fleet of independent workers grinds your pattern in parallel — the first verified match wins. The breakthrough: the found key is sealed to your X25519 key, so the worker earns the bounty yet never sees your wallet. Settlement is trustless via x402; unfilled bounties refund on expiry. Or put your spare cores to work and earn.
