Harder to lose.Harder to steal.
One Vault for your dollars and bitcoin, with three keys in three hands. A stolen key isn't enough, and Ficha alone can't move them or freeze them.1
One key, one point of failure.
Most wallets, on a phone or on a hardware device, rest on a single key and the words that recover it: whoever gets them takes everything. On an exchange, someone else holds the keys, and your savings depend on that company. In 2025 alone, Chainalysis counted 158,000 thefts from personal wallets, and more than 3.4 billion dollars stolen in all. These are some of the documented cases; their sources are at the end of the page.
Phone and computer wallets
- August 2013
- Android. A flaw in how Android generated random numbers left every bitcoin wallet created on an Android phone, in any app, open to theft. Bitcoins were stolen before it was fixed, and users had to move their funds to new keys.
- December 2014
- Blockchain.info. A bug in its web wallet reused a number that has to change with every signature, which let anyone work out the affected users' private keys. Someone who spotted it moved 267 bitcoins to safety and handed them back.
- August 2022
- Slope. Thousands of Solana wallets were drained in a few hours. Security researchers found that Slope's phone app had been sending its users' recovery phrases, unencrypted, to an outside error-logging service.
- June 2023
- Atomic Wallet. More than 100 million dollars were taken from its users' wallets, according to Elliptic. The company said fewer than 0.1% of its users were affected, and didn't confirm the cause.
- December 2025
- Trust Wallet. A compromised version of its browser extension emptied its users' wallets. The founder of Binance, which owns it, put the losses at about 7 million dollars and said Trust Wallet would cover them.
Hardware wallets
- July 2026
- Coldcard. A firmware error, present since March 2021, made the recovery phrases its devices created far less random than they should have been, so they could be guessed. Its code is public, and the error sat there for more than five years. According to TRM Labs, attackers took about 1,816 bitcoin from more than 5,200 addresses.
- October 2026
- Ledger. Devices sold by a reseller in Southeast Asia carried a hidden chip that read the 24 recovery words off the screen and sent them out over the mobile network. Ledger confirmed the implant and is investigating where in the distribution chain the devices were tampered with. It hasn't confirmed the total; researchers tracing the funds estimate more than 90 million dollars.
Exchanges
- February 2014
- Mt. Gox. It filed for bankruptcy saying 850,000 bitcoin were missing, 750,000 of them its customers'. Its creditors began to be repaid in 2024, ten years later.
- January 2018
- Coincheck. Attackers took 523 million NEM, around 500 million dollars at the time, from a wallet the exchange kept online and moved with a single key. Coincheck paid its 260,000 affected users back in yen, out of its own funds.
- January 2019
- QuadrigaCX. It stopped paying after its founder died, owing about 76,000 clients 169 million Canadian dollars. The Ontario Securities Commission found that most of that money was already gone before his death: he had traded with it and kept part of it.
- April 2021
- Thodex. It halted trading and its founder left the country, leaving more than 400,000 users unable to reach their money. In 2023 he was convicted of aggravated fraud and sentenced to 11,196 years in prison.
- November 2022
- FTX. It froze withdrawals and filed for bankruptcy: its customers' deposits had been used for other purposes. Its founder was convicted of fraud and sentenced to 25 years. Its customers began to be repaid in 2025, in dollars, at the value on the day of the bankruptcy.
In each case, everything rested on a single key or a single company. In Vault, no key is enough on its own, and the three are in different hands: yours, Ficha's, and one held by an independent company that specializes in safeguarding keys. Your Wallet has a single key too: it's for everyday money. What you can't afford to lose belongs in Vault.
What if
Your key, with Ficha's
Ficha signs with you. The backup key is held by an independent company that safeguards keys: the app shows you which one.
You don't lose your savings
After verifying it's you, Ficha and the backup company move them to a new vault, with a new key of yours.
Ficha checks before it signs
Ficha won't sign past the amount you chose, and raising it takes days. A stolen key can't empty your Vault.
One key can't move them
Whoever gets Ficha's key has one key of three. Yours and the backup key are still in other hands.
One key can't move them
Whoever breaks in gets one key of three. Yours and Ficha's work as they do every day.
The backup works without Ficha
After verifying it's you, the backup company can sign with you to move your savings to another wallet.
