Guatavita — self-custody Bitcoin wallet

What makes it different

Self-custody, for real

We hold no keys and no fragment of them. If we disappear tomorrow your funds are still yours, recoverable from your seed phrase in any standard wallet.

Standards, not cages

BIP-39, BIP-84 and output descriptors. Guatavita speaks PSBT: it builds, reads, signs and combines them with other wallets and with cold signers.

Our own stack, top to bottom

Language, compiler, cryptography, server and database — all written by us. No third-party dependencies to audit or to trust.

Spending, proven

The coin selector isn't tested with examples, it's proven: never creates dust, never overpays a fee, never sends change to a script that isn't yours.

How we work

What isn't measured isn't promised. Every piece has its own gate — and a gate that never caught anything proves nothing, so we plant faults on purpose and require them to trip.
The network is the verdict. Our transactions are validated against a real Bitcoin node, not against our own reading of the spec.
Fail closed. In doubt, the system refuses. We'd rather ship a disabled feature than one that might work with someone's money.
No hostages. Everything we hold for you exports in formats other wallets understand. Staying is a choice, not a sentence.

Guatavita is not finished and we hold no one's funds. When there is a download it will be here — with instructions to verify for yourself that the program you install is the one we published.
