How to fund (3 steps)
- Copy the wallet address above
- Send 0.005 USDC and ~0.00001 ETH on Base to that address
- The proof route will auto-detect the funds and complete the first paid x402 receipt
Make sure you're sending on the Base network (chain ID 8453), not Ethereum mainnet.
What happens after funding
Once the wallet has sufficient USDC and ETH, the next automated proof check will trigger the paid x402 call to the price endpoint. The first successful receipt becomes:
- A verifiable on-chain transaction
- Reusable proof for builder and partner outreach
- The first paid x402 micropayment on Base from SUPAH
