Chainless has no access to your money.
Every digital holding has a private key, and it works like the title deed: whoever holds the key controls the assets. That is where sovereignty over your own wealth comes from. Chainless does not hold yours. This page shows how your key is created, where it is kept and what happens when something goes wrong.

Whoever holds the private key controls the wealth.
A private key is a secret sequence that authorises moving the assets at an address. It is what proves ownership.
0.84 BTCYou hold a balance on a screen and a contract.
0.84 BTCYou hold the asset, at an address only your key can move.
It is the same amount in both columns. The difference shows up the day you want to withdraw and someone has to approve it. That is how FTX, Celsius and BlockFi locked up the money of millions of customers.
The life of your key, from first sign-in to the way out.
Six moments, and in none of them does the whole key exist on a server.
No server holds your key, and neither does Chainless
And if you lose access?
Losing your phone does not lock you out. But there is one thing to do beforehand, and it takes two minutes.
The phone
stolen, broken or replaced
Sign in on the new phone with the same account and the key assembles there. The balance was never on the old phone: it is on the blockchain.
Your Google or Apple account
minutes
The app
uninstalled or locked out
Reinstall and sign in. Nothing that matters lives inside it, because the app is only the door to your account.
Your Google or Apple account
minutes
The Google or Apple account
lost or locked
Recover the account with Google or Apple themselves, and wallet access returns with it. It is the same sign-in the network verifies.
The provider's recovery
up to them
All of it at once
or Chainless itself
Import the 12 words you exported into any wallet, on any network. It depends on neither Chainless, nor the servers, nor any login.
The 12 words you exported
immediate
Export your seed phrase and store it offline.
Two taps in the app's settings. It is 12 words: keep them off the internet, on paper stored somewhere safe, in a vault, or in a password manager only you open. It is path 04, the only one that depends on nobody.
Not even Chainless support can restore your wallet without your sign-in or your key. It is the same property that stops anyone else from touching what is yours.
And if it goes wrong?
The seven questions we would ask before putting money in here, answered by the mechanism that prevents each case.
What if Chainless goes under tomorrow?
Your assets are not at Chainless. They are at public addresses on the blockchain that only your key can move. You export the key and carry on from any other wallet. There is no creditor queue, because you were never a creditor.
What if Chainless's servers are breached?
There's no key and no piece of a key to take, and no custodied balance to transfer. A successful attack takes down the interface: the screens stop, your money doesn't.
What if a court orders your wallet frozen?
Chainless can be forced to stop serving you. Freezing or moving what is in your wallet it cannot do, because that technical capability does not exist on its side.
What if someone on the inside wants at your money?
There is no master key, no admin account and no approval queue that signs on your behalf. The signature leaves your phone, with your biometrics.
What if your phone is stolen?
The key is sealed by the security chip and every signature requires your biometrics. Holding the phone without your face, a thief signs nothing.
What if five of the nine servers go down?
Five is the minimum to release, so the network absorbs four servers being down without you noticing. If more than four fail at once, sign-in stops reconstituting the key until they are back. That is exactly the day the key you exported is for.
What if you simply want to leave?
Send to any external wallet, on whichever network you prefer, or export the key and take everything. There's no permission to request, no waiting period and no screen designed to hold you.

today MetaMask Embedded Wallets, after the Consensys acquisition in 2025
The server network that creates and releases the pieces of your key belongs to Consensys, the company behind MetaMask. It acquired that infrastructure so that nobody needs a seed phrase just to open a wallet. It is a third-party component, with public documentation and independent audits.
- SOC 2
- GDPR · CCPA · CPRA
- Penetration test
- Legal opinion on non-custody
- Security prospectus
These certifications and reports belong to the sign-in infrastructure provider, not to Chainless, which none of them audit. They are here because part of your security depends on that provider, and because you can verify them directly with it.
The phone
Apple and Google
The key is sealed by the phone's own security chip. The company that designs and defends that hardware is the device maker.

The stocks
Ondo and Ankura Trust
Every tokenized share corresponds to a real share in regulated U.S. custody, under a separate issuer protected in the event of bankruptcy. Ankura Trust verifies that backing every day.

The gold
Paxos and Tether
PAXG and XAUT represent physical gold held in LBMA-standard vaults, with monthly audits of the backing. One token, one troy ounce.

Circle and Ondo
The dollar in your wallet is USDC, from Circle. Dollar yield comes from USDY, backed by U.S. Treasury bills.

The hard questions
If yours isn't here, there are real people answering in the app.
So what does Chainless keep about me?
Account and app-usage data, plus whatever the regulated partner needs to execute conversions in reais. All of it is described in the Privacy Policy. What does not exist on our side is a key, a piece of a key, any power to move your wallet, or a record of your onchain activity.
Are you regulated by Brazil's central bank?
Chainless is not an institution authorized by the central bank, and couldn't be, because it neither custodies nor intermediates. It is the contracted technology, under art. 9, §6 of BCB Resolution 520/2025. Conversions between reais and crypto are executed by a BCB-authorized partner, which also handles tax reporting for those operations.
Is this safer than a hardware wallet?
They are different models. With a hardware wallet, access depends on one device and one paper backup, and losing both means losing the wallet. Here the day to day does not depend on those objects: access runs through your account, the confirmation of five of the nine servers, and your phone's chip. The seed phrase exists and you can export it whenever you want. It serves as an emergency exit, outside daily use. If you prefer the hardware wallet, export the 12 words and take them, because the path is open and documented.
Do you report my transactions to the tax authority?
Chainless doesn't report balances or onchain activity, because it simply doesn't hold that data. Conversions between reais and crypto are reported by the regulated partners that execute them, under Brazilian rule IN RFB 1.888/2019. In DeFi, the filing is the asset holder's own.
Do I have to trust you for anything?
Yes: the app you install, the screens, the address it shows you when you send, and the code we publish. That is exactly why the way out exists and is documented. You export the key and verify everything in any wallet or block explorer, without us in the loop.
What the architecture doesn't solve
Self-custody hands control back, and control comes with tasks that are yours.
- 01Blockchain transactions cannot be reversed. A wrong address, the wrong network, or a scam you confirmed with your own biometrics means money gone. Check before you sign.
- 02Self-custody has no deposit insurance, and digital assets really do swing. DeFi protocols are audited, but they're still code: smart-contract failure is a real risk.
- 03Blockchains are public by nature, and anyone who finds your address can read its history. That's the technology, not Chainless.
Chainless is a product of Notus Labs Ltda. (CNPJ 41.212.785/0001-43), a technology provider under art. 9, §6 of BCB Resolution 520/2025. It is not an institution authorized by the Central Bank of Brazil, does not custody virtual assets and has no access to users' private keys. Digital assets carry market risk.
