Blocto

Blocto is a Web3 smart-contract wallet built by Portto that lets everyday users interact with decentralized applications without managing seed phrases, using a chain-agnostic account-abstraction architecture. For developers, Blocto ships a client-side integration surface — the JavaScript Blocto SDK, a Blocto-flavored Flow Client Library (FCL) fork, plus Go, Swift and Rust SDKs — to connect dApps to the Blocto wallet for authentication, transaction signing and account-proof verification across Flow, Ethereum, Solana, Aptos, Polygon, BNB Chain, Avalanche, Arbitrum and Optimism. Surfaced as a 500 Global portfolio company and enriched into the API Evangelist network from its public developer documentation and GitHub organization.

Blocto is profiled on the APIs.io network. Tagged areas include Company, Web3, Wallet, Blockchain, and Account Abstraction.

Blocto’s developer surface includes documentation, getting-started guide, and 6 more developer resources.
