A. Not your keys, not your coins.

Exchanges fail, freeze, and vanish. Third-party custody is a single point of failure.

B. Lost your keys, lost your coins.

Self-custody today is fragile. Lose a seed phrase, lose everything. No recovery, no inheritance, no safety net.

Crumbling Institution

Why Now?

Paper Bitcoin ≠ Bitcoin.
Bitcoin had its AOL moment — we know what came after AOL.

Preservation, not speculation.

In high-inflation markets, Bitcoin will be used to preserve wealth — but people still need to spend from savings. Lightning, eCash, and Liquid make that possible.

Smart vaults are here.

Taproot + Miniscript unlock inheritance, recovery, and policy controls on Bitcoin. The building blocks now exist.

Trust is broken.

Mostro P2P protocol and others make fiat on/off-ramp possible without the pain of KYC. Permissionless access to Bitcoin is in demand.

AI-powered development.

AI tools are unlocking 10× productivity. A lean team powered by Claude can build what once required a department.

Three pillars of
sovereign banking.

T1

Translate

Move value between fiat and Bitcoin without asking permission or suffering a proctology exam.

T2

Transact

Send, receive, and spend Bitcoin easily — on-chain, Lightning, Liquid. It should just work.

T3

Transport

Move Bitcoin across space and time — securely, with inheritance, recovery, and policy controls built in.

COINCUBE | Marketplace

  • KYC option via Meld/Mavapay — direct fiat on-ramp / off-ramp, transact within the app.
  • P2P option via Mostro protocol — buy/sell directly with peers, decentralized and secure.

Bitcoin is permissionless money. You shouldn't need permission to buy or sell it. The Marketplace eliminates the friction of moving funds between unsafe exchanges and complex wallets — it's all under one roof.

Transact

COINCUBE | Liquid

  • Real-world utility — move funds to the Liquid Wallet for instant, near-zero-fee payments.
  • Lightning Network and Liquid Network support.
  • Pay merchants or send to friends globally without touching deep cold storage.

The Liquid wallet facilitates daily utility through immediate transactions, providing frictionless access to funds for daily spending.

COINCUBE | Vault

  • Advanced multi-sig Bitcoin wallet using Taproot and Miniscript.
  • Create additional spend paths for inheritance and recovery.
  • Time-lock funds for forced hold and security. (Coming Soon)

The Vault offers smart custody — manage wealth securely with inheritance recovery and time-locked savings. Peace of mind for the future.

COINCUBE | Connect

  • Easily back up your wallet descriptor with our Connect service.
  • Run your own Bitcoin node — or use our Esplora service free with Connect.
  • Enable Duress Mode — have a wrench attack plan already in place.
  • Powers Legacy — our inheritance and recovery protocol. Connect is the backbone that makes time-locked recovery and family key onboarding possible.

Our Connect service is the layer that lifts the Vault into a new class of self-custodial wallets — providing backup, node access, duress protection, and the infrastructure behind our Legacy inheritance protocol.

COINCUBE | Keychain

  • Turn any phone into a Bitcoin signing device.
  • Easily onboard family and friends for inheritance and social recovery.
  • Works seamlessly with the Vault.

Our companion mobile app acts as your dedicated signing device — simple inheritance, strong security, fewer hardware devices.
