Bitcoin Cash II Wallet v2.0.0

Bitcoin Cash II Wallet v2.0.0

A major release: a built-in path to the BCH2 atomic-swap DEX, QR send and receive, a broad security-hardening pass, and a fix for a subtle bug that could report a successful send as failed.

Installs as an in-place update over any 1.x build — same app, same signing key; your wallets and settings are preserved.

Highlights

Swap & trade

• New Swap entry point (wallet list banner + Settings) opens swap.bch2.org to trade BCH2 ↔ crypto/fiat, pre-filled with your receive address. Non-custodial — no keys leave the wallet.

Send / Receive

• QR scanner on Send — scan a raw address or a payment URI; the amount fills in too when present.
• QR codes on Receive — show a QR to get paid.
• Reliable sends: fixed a case where a transaction that successfully went on-chain could be reported as "failed." Sends now confirm honestly, MAX no longer over-estimates, and retrying an identical transaction is safe (idempotent).

Security hardening

• Recovery seeds now stored in the Android Keystore (migrated automatically on first launch), replacing plaintext storage.
• Certificate pinning on the wallet's server connections (renewal-stable), with a safe cert fallback for older Android versions.
• Reworked app-lock and authentication: fail-closed locking, salted key stretching, persistent brute-force protection, and re-authentication before revealing a recovery phrase.
• Airdrop claim improvements: full-history address scanning, honest network-error reporting, and a fail-safe sweep that consolidates recovered coins.

UI polish

• App-wide fix for clipped text (balances, tickers, amounts, addresses, seed-word numbers, and the network-status line) across every screen.
• Balances trim trailing zeros for readability.

Notes

• BCH2 uses the CashAddr format with the bitcoincashii: prefix.
• Direct-download APK; sideload and allow installs from your browser.
