Seismic Systems

Seismic Systems Inc. is a fintech company building a privacy-enabled ("encrypted") blockchain — a shielded EVM implementing the "Mercury" specification — that aims to power a complete stablecoin stack. Backed by a $17M seed led by a16z crypto, Seismic lets developers build private tokens (SRC20) whose balances and transfers are hidden from observers, using shielded types in Solidity, TEE-encrypted calldata (ECDH + AES-GCM), and authenticated "signed reads." It ships first-party client SDKs for TypeScript (seismic-viem, seismic-react), Python (seismic-web3), and Rust (seismic-alloy), an sfoundry developer toolchain (sforge/sanvil/ssolc), a public testnet with a faucet and block explorer, published Claude Code agent skills, and a read-only SRC20 Factory REST API for querying deployed tokens.

Seismic Systems publishes 1 API on the APIs.io network: tokens API. Tagged areas include Company, Blockchain, Privacy, Encryption, and Stablecoins.

Seismic Systems’ developer surface includes documentation, API reference, getting-started guide, support, CLI, sandbox, authentication, and 12 more developer resources.
