Specter wallet running on iPhone
Wallets

Hold any number of wallets, side by side

Create or restore wallets from a seed phrase, xpub, or descriptor. Every key stays on the device — there is no account, no email, and no server-side copy.

  • BIP-39 12 or 24-word recovery phrases
  • Watch-only via xpub or descriptor
  • Independent wallets, switch instantly

  • Create wallet

    Fresh BIP-39 phrase generated locally with system entropy.

  • Import wallet

    Restore from seed, xpub, or descriptor in a single screen.

  • Multiple wallets

    Run as many wallets as you need — switch with one tap.

  • Wallet naming

    Label every wallet so you never spend from the wrong one.

  • Backup reveal

    View your recovery phrase any time, gated by device auth.

  • XPUB details

    Inspect extended public keys for accounting or watch-only.

Security

Locked down at every layer

Keys never leave the device. Sensitive screens are protected from screen capture. Every cryptographic operation happens on-device.

  • App-lock passcode + biometric unlock
  • Screen-capture blocking on sensitive views
  • No telemetry, no analytics, no profiling

  • App-lock passcode

    A numeric passcode gates the entire app on cold launch.

  • Biometric unlock

    Face ID and Touch ID — the OS verifies, Specter never sees biometric data.

  • Screen-capture protection

    Screenshots and screen recording are blocked on seed reveal and key views.

  • Local-only storage

    Keys, addresses, history — all stored exclusively on the device.

  • Pseudonymous by default

    No account, no identity binding, no usage telemetry. Open and use.

Send & receive

Move bitcoin on your terms

Pick the sat/vB rate yourself, attach a custom amount to a receive request, scan QR codes, or push a pre-signed raw transaction directly to the network.

  • Custom fee selection per transaction
  • Receive with a custom amount baked into the QR
  • Broadcast pre-signed transactions or PSBTs

  • Send with custom fees

    Pick the sat/vB rate or follow the mempool estimator.

  • QR scan & generate

    Scan a payment request or share your own with a custom amount.

  • Address validation

    Every address is decoded and checksum-verified before broadcast.

  • Broadcast custom TX

    Paste a signed raw transaction or PSBT and push to the network.

Multisig

Multi-signature for serious holdings

Set up M-of-N policies and require quorum on every spend. Specter handles PSBT signing and combining so cosigners stay in sync.

  • Any M-of-N configuration (2-of-3, 3-of-5, etc.)
  • PSBT-based workflow for cosigners
  • Compatible with descriptor-based hardware signers

  • M-of-N policies

    No transaction moves until your chosen quorum signs.

  • PSBT workflow

    Sign and combine partially signed bitcoin transactions across cosigners.

  • Hardware-friendly

    Pair descriptor-based hardware signers via PSBT export.

Coin control

UTXO-level control

Decide which coins move and which stay private. Browse every UTXO, tag them by source, and hand-pick inputs for each transaction.

  • Per-UTXO selection
  • Local-only coin tagging
  • Privacy-preserving spend construction

  • Per-UTXO selection

    Browse every output and freeze or include them per transaction.

  • Coin tagging

    Label UTXOs by source or intent. Tags persist locally only.

  • Privacy-preserving spends

    Avoid linking sensitive UTXOs by hand-picking inputs.

Network

Talk to Bitcoin directly

No proprietary backend in between. Point Specter at your own Electrum node, pick a block explorer, and connect to mainnet directly.

  • Custom Electrum server endpoint
  • Choose your preferred block explorer
  • Direct connection to Bitcoin mainnet

  • Custom Electrum server

    Point Specter at your own node or a public server you trust.
