Send a payment with a reference

> pay 10 usdc to 0x... for invoice-42 on base
Skopos builds a transfer for you to sign — non-custodial, same as every other execution path. What makes this different from a plain transfer is the memo: invoice-42 travels on-chain attached to the transfer, so whoever receives it can reconcile the payment automatically instead of matching amounts and timestamps by hand.

​
How the memo actually attaches

  • If the token is a B20 token (Base’s memo-native token standard, detected by its 0xb200… address prefix), Skopos uses transferWithMemo — the memo is emitted as part of the same on-chain Memo event as the transfer.
  • If it’s a regular ERC-20, Skopos falls back to a plain transfer() and tells you the memo couldn’t be attached on-chain. The payment still goes through — you just lose the automatic reconciliation.

​
Resolving the token

You can name a token by symbol (Skopos checks a verified map first, then Delora’s broader token list) or paste a contract address directly.

Looks up incoming transfers tagged with a memo, across both Base mainnet and Base Sepolia.

Chain support

Payments with memo support currently work on Base and Base Sepolia. Other chains can receive a plain transfer, just without the on-chain memo.
