Resolve any .btc, .sats, .unisat, .x, .xbt, or .sat name to Bitcoin addresses, cross-chain records, Ordinal avatars, and more. BNRP is the open protocol spec that makes it work — built on Bitcoin, no vendor lock-in.
Paste any Ordinals inscription ID to preview it as a BNRP avatar. This is what wallets and apps will display when a name sets an ord: avatar record.
A .btc, .sats, .unisat, .x, .xbt, or .sat name is an Ordinals inscription. Ownership is determined by who holds the UTXO — verifiable on any Bitcoin node. No registry contract, no trusted database.
The name owner inscribes a routing record linking their name to Bitcoin addresses, cross-chain addresses (ETH, SOL, Base, Arbitrum), an Ordinal avatar, and web content.
A self-transfer makes a name the wallet's primary identity. Any app can reverse-resolve a raw Bitcoin address to a human-readable name — with mandatory anti-spoofing verification.
Any party can run a BNRP-compliant resolver. No vendor lock-in. Wallets, explorers, and dApps query the standard REST API — same interface regardless of who runs the indexer.
Full architecture, all JSON schemas, security model, roadmap, and migration path from BtcName.
BNRP-IP-01Unicode NFC, case folding, label validation, reserved names, IDN/homoglyph rules.
BNRP-IP-02On-chain record format: Bitcoin addresses, SLIP-44 cross-chain schema, avatar, content, bitmap fields.
BNRP-IP-03Solution B (self-transfer) as canonical default. Solution A (explicit inscription) as extended option.
BNRP-IP-04Bidirectional anti-spoofing: reverse lookup only succeeds when forward resolution confirms the address.
BNRP-IP-05ord:, ipfs:, ipns:, https: — with Ordinals ownership verification and fallback chain.
8-endpoint open API any resolver must implement. Full TypeScript SDK interface included.
CommunityBNRP is an open standard. Propose changes, run a resolver, or co-author the next BNRP-IP.
