RedWallet is an early Android beta for Bitcoin (XBT), based on BlueWallet.
Create or restore BIP39 Native SegWit or BIP86 Taproot wallets, send and receive with QR codes,
view wallet history, and connect to your own Fulcrum server.
Authenticated TLS supports explicitly trusted private-server certificates.
Supported spends use SIGHASH_UNIFIED (0x21). XBT watch-only accounts can
prepare PSBT requests for compatible external signers; physical cold-wallet
interoperability still needs testing.
USDC estimates use a manual quote or optional NeoxEX pricing.
Password-encrypted storage, decoy wallets, authenticated secret exports,
and fee/recipient confirmations are supported.
This beta passed automated and Android emulator checks. The maintainer does
not own an Android phone and has not personally tested this Android build.
Begin with an empty disposable wallet and retain an offline recovery backup.
Do not downgrade after upgrading encrypted storage.
Taproot key-path spending and opt-in BIP86 watch-only signed-PSBT returns
require an XBT Unified-capable signer. RBF preserves recipients and inputs,
funding higher fees from sufficient change. CPFP prices one unconfirmed parent
plus child. Return a signed PSBT; raw signed hex is unsupported. Requests bind
the current app session; after restart, create and sign a fresh request.
No Taproot script paths, annexes, multisig, RBF cancellation or added inputs.
Physical cold-device and funded physical-phone interoperability are unverified.
Independent header-chain/merkle verification remains unimplemented.
The configured Fulcrum server remains trusted for chain state.
No community/default server is bundled; configure your own Fulcrum server.
Screenshots show an earlier empty demo wallet on an emulator; the manual 3.12 USDC
quote is illustrative, not a market price. Do not fund the pictured address.
Thanks to BlueWallet and the contributors, reviewers and testers.
