Update from Tirai

Tirai Update: week of 28 Sep – 4 Oct 2026

• Upgraded to 128-bit security (post quantum safe), with zero-knowledge and a new proof family. Proving measured on a phone at 1.49 s.

• The cross-chain corridor now runs trustlessly on testnet. Solana → Sepolia, with the claim released through our ZK light client rather than a mock oracle. Shipped alongside it: the solver, solver repayment, transfer status on the Send page, and a public activity view.

• Testnet is a product, not a harness. A single pool per network, a faucet, plain-language screens with no cryptography jargon, and demo walkthroughs that run real transactions.

• Security work ahead of exposure. Several high-severity issues in the new stack were found and fixed internally before the stack was opened to anyone, including three in the verifier path.

• New brand and institutional landing page, with product claims trimmed to what is built and roadmap items labelled as roadmap.

For testers

Everything below is testnet. Use a throwaway wallet — never a wallet holding real funds.

1. Go to testnet.tirai.io.

2. Connect a wallet: Phantom for Solana, MetaMask for Ethereum Sepolia or Arbitrum Sepolia. On Solana only Phantom works; if you pick another, the app will tell you.

3. Use the faucet on the Deposit page to get test tokens. You also need a little devnet SOL (or Sepolia ETH) for fees. Get devnet SOL from here https://faucet.solana.com/

4. Run the flow in order: Deposit → Send → Withdraw. Check Activity after each step.

5. For the cross-chain test, use Send from the Solana pool with Ethereum Sepolia as the destination. You'll be paid on Sepolia within a minute or two; the Activity page tracks the status.

6. Your proof is generated in your browser, which takes a few seconds and may spin the fan. Keep the tab open and the screen awake until the page says it's done.

7. Reporting a problem? Send me the network, the page, what you expected, and the transaction signature or hash if you have one. Screenshots of the error text help. Please don't post wallet seed phrases or private keys anywhere, including to me.
