One line replaces complex SDK integration

Compare traditional protocol SDKs vs Sona Kit

Traditional SDK

Complex, vulnerable

Sona Kit

Simple, attested

One line generates a complete transaction. Built in a secure enclave isolated from your application code, every transaction is cryptographically attested and protected from supply chain attacks.

The Problem

DeFi is vulnerable

Traditional DeFi transactions are opaque and vulnerable. Users can't verify what they're signing. Malicious dependencies can inject code. Enterprises can't prove transaction integrity.

  • ✗Vulnerable to supply chain attacks in dependencies
  • ✗No guarantees about transaction contents
  • ✗Complex transaction building creates attack surface
The Solution

One line. Secure by default.

Sona generates complete, attested transactions with a single method call. Built in a secure enclave, isolated from malicious dependencies. Every transaction is cryptographically verified and ready to sign.

  • One line to generate any Solana protocol transaction
  • Protected from supply chain attacks
  • Automatic cryptographic attestation on every call
