Voluntary test contribution
This is an x402 payment experiment, not a purchase. No goods, service, access rights, special treatment or investment return are provided. All site content remains free.
0.01 test USDC on Base Sepolia only (chain ID 84532). Test tokens have no financial value and are not real USDC. Mainnet payments are disabled.
Receiving public address: 0xF89FfB82f5F3dF83f68062a1b0d3BAA6A1005735.
Token: 0x036CbD53842c5426634e7929541eC2318f3dCF7e (6 decimals; amount 10000).
No refunds are offered for voluntary test-token contributions. This does not waive rights required by applicable law.
The public testnet facilitator normally pays EIP-3009 settlement gas; this flow requests no payer ETH, token approval or mainnet funds. No facilitator charge is planned for this testnet trial. Check Rabby before signing and stop if different costs or permissions appear.
Authorization and public records
Only the wallet owner may authorize payment. An AI needs explicit owner permission; visiting or connecting does not authorize a transfer. The EIP-712 signature authorizes this test-token transfer, not a harmless login.
Blockchain addresses and transfers are public. In a separate private payment ledger we store a payment ID, fixed terms, UTC date, status and transaction hash; no raw signature/payment payload, payer address, IP, UA or visitor identifier is logged by our application. The browser session retains only the payment ID to retrieve the receipt. Wallets and infrastructure providers have their own data processing. No payment log or transaction list is published.
The trial is limited to 5 attempts per UTC day and 20 in total, including unsigned starts. Records are retained through this bounded experiment; deleting/resetting IDs will not reopen old authorizations. Anyone can exhaust the small quota. Duplicate IDs return the existing result; uncertain settlement stops for reconciliation. Do not sign/pay again with a new ID when a result is pending.
Try with Rabby browser extension
Receiving alone needs no connection, signature or funds. A payer needs test USDC on Base Sepolia; obtain it yourself from the Circle testnet faucet, choosing USDC and Base Sepolia. Add the network using Rabby's official guide: RPC https://sepolia.base.org, chain ID 84532, currency ETH. A self-transfer to the same receiving address may test authorization but would not increase its net balance; actual compatibility remains to be tested.
