It lets developers define predicates for the on-chain events they care about and send matching events to files or HTTP endpoints. ### Project history The official README describes Chainhook as a transaction indexing engine for reliable blockchain data across forks and reorgs, focused on lighter indexes and IFTTT-style predicates. Hiro's August 2023 release roundup says Hiro launched Chainhook as an open-source engine for efficient indexing and webhook-style triggers. ### Adoption history The README documents Homebrew installation for macOS, Snap for Linux, Winget for Windows, GitHub release builds, and source builds with cargo. Hiro later described programmatic API access for platform-hosted chainhooks, and 2025-2026 Hiro posts describe Chainhook 2.0/v2 testing, beta, and general availability, showing the concept moved from local CLI engine into hosted platform infrastructure. ### How it is used Developers create predicate JSON files for Bitcoin or Stacks, scan chain data with a local bitcoind or Stacks node, and route matches through actions such as HTTP POST or file append. The README covers txid, output, OP_RETURN, Ordinals, Stacks asset, event, contract-call, and contract-deployment predicates. ### Why package nerds care Chainhook is notable because it packages blockchain indexing as a developer-controlled CLI rather than only as a hosted API. For package ecosystems, it is also a Rust/Cargo-era tool distributed through Brew, Snap, Winget, source builds, and GitHub releases, aimed at developers who need reproducible local and CI behavior around on-chain events. ### Timeline - 2023: Hiro launched Chainhook as an open-source engine for efficient indexing and webhook-style triggers. - 2024: Hiro released Chainhook v1.3.0 with Prometheus metrics support. - 2025: Hiro reported Chainhook 2.0 alpha testing and later limited-access beta. - 2026: Hiro announced Chainhooks v2 generally available and migration away from hosted v1. ### Related projects - Chainhook is related to the Stacks Blockchain API, Hiro Platform, Clarinet/devnet workflows, bitcoind, Ordhook, Ordinals indexing, and Bitcoin/Stacks node infrastructure. ### Sources - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** chainhook - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - winget - HiroSystems.Chainhook: normalized package name match | Windows Package Manager source index: HiroSystems.Chainhook from https://cdn.winget.microsoft.com/cache/source.msix ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [clarinet](https://www.automicvault.com/pkg/brew/clarinet/) - Shares av.db curated category or tags: blockchain, cli, developer-tools, stacks. - [anchor](https://www.automicvault.com/pkg/brew/anchor/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [idutils](https://www.automicvault.com/pkg/brew/idutils/) - Shares av.db curated category or tags: cli, developer-tools, indexing. - [ignite](https://www.automicvault.com/pkg/brew/ignite/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [solana](https://www.automicvault.com/pkg/brew/solana/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [stellar-cli](https://www.automicvault.com/pkg/brew/stellar-cli/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [sui](https://www.automicvault.com/pkg/brew/sui/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [tendermint](https://www.automicvault.com/pkg/brew/tendermint/) - Shares av.db curated category or tags: blockchain, cli, developer-tools. - [foundry](https://www.automicvault.com/pkg/brew/foundry/) - Local package facts share a topical domain.
