Lazer 0.1.1 · Testnet transfer updates
Pre-release
Lazer is publicly available with funded Bitcoin Testnet 4 accounts, a shared limit order book, atomic trade settlement, cancellation, and signed withdrawals to Bitcoin Core. USD is simulated.
This update checks pending deposits and broadcast withdrawals automatically while the page is visible. Unchanged confirmation checks do not grow the ledger. Manual refresh and retry of the same prepared transaction remain available.
Verification: 23 checks passed, including production API handlers against local D1 SQL. Concurrent deposits credit once, concurrent orders cannot overspend, and competing withdrawals cannot reuse an input. API tests explicitly use fixture authentication and chain data. TypeScript and the production build passed in GitHub Actions.
The full deposit, Alice to Bob trade, and 15,000 satoshi withdrawal cycle passed against Bitcoin Core regtest with six confirmations and a 143 satoshi fee. This is separate from public Testnet evidence.
Public Testnet status at 03:06 UTC on September 17, 2026: the 100,000 satoshi deposit has one confirmation, independently verified by Bitcoin Core. The hosted interface automatically updated to 1/6. The funded hosted trade and withdrawal round trip remains pending until the deposit reaches six confirmations.
This release is a Testnet pilot with bounded capacity and server held test keys. Mainnet custody and real USD are not supported. See the README for setup, operating limits, backup requirements, and reproducible tests.
