Bitcoin Name System (BNS) operations — lookup names, reverse-lookup addresses, check availability, get pricing, list domains, and register new .btc names using single-transaction claim or two-step preorder/register flow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# BNS Skill
Provides Bitcoin Name System (BNS) operations for .btc domain names using BNS V2 (recommended for .btc) with fallback to BNS V1. Read operations work without a wallet. Write operations (claim-fast, preorder, register) require an unlocked wallet.
## Usage
```
bun run bns/bns.ts <subcommand> [options]
```
## Subcommands
### lookup
Resolve a .btc domain name to its Stacks address.
```
bun run bns/bns.ts lookup --name <name>
```
Options:
- `--name` (required) — BNS name to lookup (e.g., `alice.btc` or `alice`)
Output:
```json
{
"name": "alice.btc",
"found": true,
"address": "SP1...",
"namespace": "btc",
"expireBlock": 900000,
"network": "mainnet"
}
```
### reverse-lookup
Get all BNS domain names owned by an address.
```
bun run bns/bns.ts reverse-lookup [--address <addr>]
```
Options:
- `--address` (optional) — Stacks address to lookup (uses active wallet if omitted)
Output:
```json
{
"address": "SP1...",
"network": "mainnet",
"namesCount": 2,
"names": ["alice.btc", "myname.btc"]
}
```
### get-info
Get detailed information about a BNS domain name.
```
bun run bns/bns.ts get-info --name <name>
```
Options:
…Read the whole file at its exact version.
How to install
mdr add aibtcdev/skills/bns@sha256:c07a5747286deb2fThe line at the top of this page pins the label git:20260313.03adaab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
