About the Company
Openfort supplies wallet infrastructure to developers building crypto and stablecoin products. Its stack covers embedded wallets, key management and transaction automation, plus backend wallets reachable through a REST API for signing, payouts and transactions, with EIP-7702 and Solana support.
A separate agent-wallet product applies spending policies and session keys to AI agents, and OpenSigner handles self-hosted key management. Official SDKs for JavaScript/TypeScript, React, React Native, Swift and Node.js are published on GitHub under the openfort-xyz organization, alongside a CLI, an MCP server and an OpenAPI spec. A free tier includes 2,000 operations per month, according to the company's site.
