Angor is a fully decentralized P2P funding protocol on Bitcoin.

Founders raise capital in predetermined stages secured by Taproot
time-lock contracts; investors retain control and can recover any
unspent funds at any time. Project metadata flows over Nostr, so
no central server holds the listing.

Features:

Stage-based fund release via Bitcoin Taproot
Investor-side recovery of unspent funds
Nostr-native project discovery and messaging
Self-custodial wallet, no account required
