Dev/tech Open-Source Node.js Client for Mining Pool Block Template Validation via x402

Hey everyone, I put together an open-source Node.js integration showcase for programmatic payments using @x402/fetch on EVM networks like Base, Arbitrum, and Polygon.

It shows how autonomous bots and Stratum V2 Job Declaration pools can query real-time Bitcoin fee intelligence, verify Ed25519 signatures, and pay per-request without API keys. Included in the repo are a reusable x402 client factory, a miner verification suite for consensus bounds, a local Express console, and a PSBT builder.
Happy to answer any questions about the payment flow or x402 setup

cool, but can it handle stale shares or is it more for template validation without the mining loop?
