Tempo

Ready · ModeratoTempo Moderato

AlphaUSD with the payment id as the TIP-20 memo; the operator pays the fees.

What runs on Tempo

  • Payments move AlphaUSD, a TIP-20 stablecoin, on Tempo Moderato.
  • Every transfer carries its payment id as the TIP-20 transfer memo (32 bytes; a longer id is hashed to fit).
  • The operator's treasury co-signs every transfer from a Dial wallet as fee payer, and fees are paid in AlphaUSD, so Dial wallets only ever hold the stablecoin.
  • A transfer counts as delivered only when its Transfer log shows the amount reaching the recipient: a receive policy can block funds in a transaction that still succeeds.
  • On testnet the treasury tops itself up from the Tempo faucet when it runs low.
  • Pay pages (/@handle) give an EIP-681 link with the token and Tempo's chain id.
  • Split payments: "split $30 between @a @b @c" pays everyone their share in one Tempo transaction.

Swap @handle for anyone on Dial, or for a phone number. The operator texts back a 6-digit code; reply with it, and the receipt links the transaction. Your first payment on Tempo opens a wallet there with a small drop of test money.

Built for Tempo

What Tempo lets the operator do beyond sending money, each with a demo you can use here. The demos only read: they send no texts and move no money.

Split payments

One payment to several people, settled as one transaction.

  • Text "split $30 between @a @b @c", or "split $30 with @a @b" to take a share yourself. Agents use the split_payment MCP tool. Up to 10 people, and the shares differ by at most a cent.
  • One code approves every share. All the shares go in one Tempo transaction, a list of TIP-20 transferWithMemo calls that run atomically: every share lands, or none do.
  • Each share carries its own payment id as its memo. A share for someone not on Dial yet lands in a wallet held for them, in the same transaction, and waits to be claimed.
