kexify for developers
What you can build and test with kexify today. Most tools sit in Expert mode: free, off by default, in Settings.
Connect dApps with WalletConnect
Pair a dApp by pasting its WalletConnect URI or scanning the QR code. Works with EVM chains, Solana and TRON, and every request opens a readable review.
Details →Testnets
Sepolia, Base Sepolia, Solana devnet, TRON Nile, Bitcoin testnet and more. Turn on Expert mode, then test networks, in Settings.
Details →Expert mode tools
Nonce and fee overrides, UTXO selection, RBF speed-up, raw message signing and sign-only with a separate broadcast. You can also point any chain at your own RPC.
Details →Recovery without the server, and the CLI
With your key file and the server's key file, recovery mode signs in your browser with no kexify server. The open-source CLI can rebuild the private key or answer WalletConnect requests locally.
Details →Open-source MPC (cb-mpc)
Signing uses 2-party ECDSA and EdDSA from Coinbase cb-mpc, through our MIT fork. The web app and the CLI are MIT too.
Details →Developer API (coming soon)
Not available yet. Planned: a free read-only API for your own wallets, and a signing SDK and webhooks on Premium.

Needs Node.js and both key files. Nothing is sent to any server.
