ERC-4337 and EIP-7702 in one SDK
Openfort treats smart accounts as first-class citizens with native support for ERC-4337 and EIP-7702. Deploy new smart accounts or upgrade existing EOAs without changing addresses. Sub-100ms creation, 100–150ms signing — benchmarks public at openfort.io/benchmarks.
Gasless transactions built in
Built-in paymasters sponsor gas so your users never need to hold native tokens. Bundler-agnostic — use Openfort’s defaults or route through Pimlico, Stackup, or self-hosted. One SDK either way.
Programmable permissions per action
Session keys scoped by contract address, function selector, spend cap, and expiry. Ship game inventories, agent payments, and recurring user actions without re-prompting the user for every signature.
