Lazer 0.1.3 · Public Testnet trading
Pre-release
Lazer has completed a funded trade and withdrawal on the public Bitcoin Testnet 4 network, independently checked with Bitcoin Core. The website and source are public. Dollar balances are simulated.
The live test used a 100,000 satoshi deposit, credited to Alice after eight confirmations. Alice then sold 20,000 satoshis to Bob at 60,000 dUSD per Bitcoin, settling 12 dUSD through the shared order book.
Bob withdrew 15,000 satoshis to his Bitcoin Core wallet, paying a 143 satoshi miner fee. The withdrawal spends the actual deposit output and returns 84,857 satoshis as exchange change. Core independently verified the exact receiving address and amount. At 04:57 UTC on September 17, 2026, Bitcoin Core reported seven confirmations. Lazer independently marked the withdrawal confirmed after its six confirmation threshold. The complete public deposit, trade and withdrawal cycle is verified.
The final exchange balances are Alice: 80,000 satoshis and 100,012 dUSD; Bob: 4,857 satoshis and 99,988 dUSD. No open orders or balance reservations remain. Retrying the saved withdrawal preserved its transaction ID and did not debit Bob twice.
This release also prevents reuse of old withdrawal identifiers after request receipts expire, keeps every open order visible and cancellable regardless of recent history, and preserves an acknowledged broadcast while the explorer indexes the transaction. Pending transfers are checked automatically while the page is visible.
All 26 automated checks, TypeScript checks and the production build passed in GitHub Actions. The automated API tests use local D1 SQL with explicit authentication and chain fixtures. Separate Bitcoin Core regtest coverage and this public Testnet evidence are documented independently.
Lazer is a bounded Testnet pilot. Mainnet Bitcoin and real USD are not supported. See the README for setup, operating limits, wallet secret backups and reproducible verification commands.
