Libraries, SDKs, and developer tools for building on Bitcoin Stamps: unprunable data storage on Bitcoin's UTXO set. Stamps embed data directly in Bitcoin transactions where node operators cannot prune it, making every stamp a permanent on-chain artifact.
btc-stamps is the tooling and libraries home. The reference indexer, public API, and protocol specifications live in the sibling stampchain-io organization. Founded by mikeinspace, Arwyn, and Reinamora; mascot: KEVIN.
SRC-20 (fungible tokens) · SRC-101 (naming) · SRC-721 (NFTs) · SRC-721r (recursive stamps) · OLGA (P2WSH encoding)
