Walour

The brief

Walour is a real-time security layer for Solana users, live in production. It reads a transaction before it is signed and explains, in plain language, what it will actually do. It ships three ways: a browser extension, an SDK developers drop into their own apps, and an on-chain oracle. It began as a build for the Solana Frontier hackathon and was carried all the way through to production.

What we did

• Scores a transaction in under 400ms across a six-layer check
• Ships as a browser extension, an SDK, and an on-chain oracle
• Backed by a live database of 59,000+ indexed threats
• AI writes a plain-language summary of what each transaction does

The outcome

Live in production and shipped three ways: a browser extension, an SDK, and an on-chain oracle. It scores a transaction in under 400ms against a database of 59,000+ indexed threats, then explains in plain language what signing it would do.
