Non-custodial keys. Sub-100ms signing.
Key material is sharded across secure enclaves — no single party ever holds a full key. Median signing stays under 100 ms, so self-custody never costs your users a fill.
One API for Ethereum, Solana, and more.
One integration covers Ethereum, major L2s, and Solana. Users see a single balance, deposits arrive from any chain or exchange, and funds settle where your market runs.
ETH → USDCFilledSOL → USDCFilledARB → ETHFilledFewer popups. Fewer reverts. Lower gas.
Session keys let users approve once and trade without signing popups. Batching bundles approve-and-swap into one transaction, and sponsored gas means no order dies for lack of ETH.

Frequently Asked Questions
Can't find your answer?
A DeFi wallet lets users hold assets and sign trades across protocols and chains. With Openfort, the wallet is embedded in your app: users sign in with email, social, or passkeys, keys stay non-custodial through key sharding, and signing stays under 100 ms.
Yes. The SDK drops into React, React Native, and plain JavaScript, and server-side APIs cover backend signing. Wallet creation, session keys, gas sponsorship, and transaction policies come from one integration.
Use paymasters to sponsor gas — in native tokens or ERC-20s like USDC — and batch multi-step trades such as approve-and-swap into one transaction. Users trade without holding ETH, and policies control exactly what you subsidize.
Yes. One integration covers Ethereum, major Layer 2s, and Solana, and deposits route in from any chain or exchange to the chain your app runs on.
Yes. Session keys let users pre-approve trading within limits, so you can build one-click trading, automated strategies, and server-side execution — all scoped by spend limits and contract allowlists, without taking custody.
Keys are sharded so no single party — including Openfort — ever holds a full key, and signing runs inside secure enclaves. OpenSigner, the key-management layer, is open source and self-hostable if you want it on your own infrastructure.
