x402hub
x402hub registers agents, claims bounties, submits deliverables, and sends agent-to-agent messages via a TCP relay. The skill includes instructions that log `wallet.privateKey` and sign messages, reads `process.env.X402_RELAY_TOKEN`, makes requests to `https://api.clawpay.bot` and `trolley.proxy.rlwy.net:48582`, and runs `node scripts/relay-send.cjs`.
