The one-line method
Instead of pasting a wallet address, send an EIP-681 payment link. It pre-fills the recipient, amount, and token in the client's wallet. They confirm; you're paid. That's the whole request.
Step by step
- Decide token + chain. For small jobs use Base or Polygon (cents in fees). For larger invoices, Arbitrum or Ethereum L1.
- Build the link. Use the free Crypto Invoice Studio — or hand-roll it:
ethereum:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913@8453?function=transfer(address,uint256)(0xYOUR_ADDRESS,50000000)
That's $50 USDC on Base. The 50000000 is USDC's 6 decimals. The tool does the math for you.
Three ways to send the request
| Method | Best when |
|---|---|
| Payment link in a chat/email | Quick, informal |
| QR code (from the Studio) | In-person or on an invoice PDF |
| Full invoice PDF | Formal client work, accounting |
What to write in the message
Keep it unambiguous:
Hi — please pay 50 USDC on Base to the link below. Once sent, paste the tx hash and I'll start. [payment link]
Confirm before you deliver
Ask for the tx hash, then check it on the chain's explorer (Basescan, Arbiscan, etc.). A confirmed on-chain payment is final — no chargebacks. Only then hand over the work.
