Twoonie

Consumer Apps

Twoonie rounds up every Canadian purchase to the nearest dollar and automatically invests the spare change on Solana.

Sign up with email and your wallet is created invisibly. Most Canadians have no investment account not because they do not want to invest but because the barrier is too high. Twoonie removes that barrier completely.

Create an agent, launch its token, sell its services, earn. Fully on chain, no middlemen.

Security Tools

Uwill is a Solana-based CAPTCHA network that turns standard "I'm not a robot" into interactive visual puzzles built from real, constantly changing brand advertisements. It allows AI Agents to access websites using Pay Per Agent model, meaning publishers set a fixed price on each solve and agents pay using Solana micropayments. In turn, website owners can easily monetise their traffic to the real audience and collect ad revenue directly in Solana.

uWu Protocol

DeFi

uWu Protocol is a trustless verification settlement layer on Solana for cross-border crypto-fiat trades. A seller locks SOL in an on-chain escrow vault. A buyer pays fiat (e.g., INR via UPI) directly to the seller. Our oracle integrates with the Setu Account Aggregator to verify the payment and sign an Ed25519 attestation, triggering the vault to auto-release the SOL to the buyer. No custody, no intermediaries, and zero trust required.
