Entropy

Entropy is a threshold-signature network for trustless, programmable key management and distributed key generation (DKG). Positioned as "the Autonomous Agent Network," Entropy lets users and agents produce cryptographic signatures without any single party ever holding the private key, using on-chain WASM "programs" that define the exact conditions under which a signature may be generated. Built as a Substrate-based blockchain with a network of Threshold Signature Scheme (TSS) servers running inside Trusted Execution Environments (TEEs), Entropy delivers secure crypto custody, programmable signing, and distributed key management for Web3 and autonomous-agent use cases. Backed by a16z and surfaced into the API Evangelist network via the venture-portfolio pipeline.

Entropy is profiled on the APIs.io network. Tagged areas include Company, Cryptography, Threshold Signatures, Distributed Key Generation, and Key Management.

Entropy’s developer surface includes documentation, engineering blog, support, CLI, changelog, and 11 more developer resources.
