ARC Transaction Broadcasting
Broadcast signed BSV transactions using the ARC (Application Runtime & Certificate) protocol via @bsv/sdk.
ARC Overview
ARC is the production-grade transaction broadcaster for BSV. Unlike simple REST broadcast endpoints, ARC:
- Connects to multiple nodes simultaneously (no single point of failure)
- Accepts Extended Format (EF) transactions for script/fee validation
- Returns structured status responses with
txStatus - Supports callback webhooks for confirmation events
- Handles rebroadcast automatically
Two public ARC endpoints are available:
| Provider | URL | API Key Required |
|---|---|---|
| GorillaPool | https://arc.gorillapool.io |
No (mainnet, public beta) |
| TAAL | https://api.taal.com/arc |
Yes — get from console.taal.com |
