Iron Fish is a zero-knowledge Layer 1 blockchain that brings optional, best-in-class privacy to cryptocurrency. Built on zk-SNARK cryptography, it lets anyone send, receive, and bridge assets privately across 20+ EVM-compatible chains while running their own node. For developers, Iron Fish exposes a self-hosted node RPC server (over TCP, IPC, and HTTP with JSON and streaming responses) organized into chain, wallet, node, peer, miner, config, event, mempool, and worker namespaces, plus a hosted public REST API at api.ironfish.network powering the block explorer and faucet. Integration is supported by a first-party JavaScript SDK (@ironfish/sdk), Rust/Node bindings, and the ironfish CLI for node operation, wallet management, mining, and multisig. Backed by a16z and Electric Capital.
