On-chain bitcoin tips — no zap servers, no LNURL
infrastructure, no custodians. A profile publishes a btc /
btc_test address in its kind-0 (the
profile editor has
the fields); the tip button shows a BIP-21 QR and a mempool link.
Testnet by default while the convention settles.
Paste a pubkey/npub whose profile carries an address —
or set btc_test on your own profile and paste yourself:
After paying, the tipper can optionally paste the txid to
announce the tip on nostr — a plain kind-1 tagged
['t','onchain-tip'], so tips are queryable without any receipt
server.
