Send to a .sol name

Pay someone's Crepus name in SOL or any SPL token.

Paying a Crepus name feels like any other payment. The difference happens in your browser: it computes a fresh address for the recipient before the transaction is built.

Step by step

  1. 1

    Enter the name

    Type bob.sol or open their pay link. The app reads Bob's meta-address from the registry.
  2. 2

    Choose token and amount

    SOL or any SPL or Token-2022 token in your wallet.
  3. 3

    Your browser derives the address

    A random one-time key produces the address only Bob can open. The key is used once and thrown away.
  4. 4

    Approve in your wallet

    One transaction calls crepus_pay, which pays the address and emits the announcement Bob's scanner looks for.

Sending tokens? You can attach a little SOL for the recipient's fees; crepus_pay forwards it untouched. It is optional, since a relayer can pay the recipient's fees too.

What the chain records

Your address, the one-time address, the amount and the announcement. Bob's wallet does not appear. See the Security model for the full picture.
