What a non-custodial wallet is — and why only you should hold the keys

Who really owns your crypto?

It sounds strange: you bought the coins, the app shows your balance — so surely they're yours. But in crypto, ownership isn't defined by a number on a screen. It's defined by who holds the keys. And that's exactly where the main dividing line runs — between custodial and non-custodial wallets.

In a custodial wallet, the keys are held by a platform: an exchange, a service, an app. You see a balance and press buttons — but in reality you're asking an intermediary to move your funds on your behalf. That's convenient right up until the platform stops working, blocks withdrawals, or runs into trouble.

In a non-custodial wallet, the keys exist only with you. Nobody keeps your money "in safekeeping", and nobody can move or freeze it without your signature. You are the single point of control.

The private key and the recovery phrase

Behind every crypto wallet is a private key — a long sequence used to sign transactions. Whoever knows the private key controls the funds. No human can memorize it, so the key is represented as a 24-word recovery phrase (also called a seed phrase).

Those 24 words are your wallet. Not an account password you can reset over email, but the very root of access to your money. Enter them into any compatible wallet and you get access to the same funds. Lose them, and there is no way to recover.

This principle — not your keys, not your coins — didn't become crypto's ground rule by accident. Every time yet another platform halted withdrawals or collapsed outright, the same thing came to light: users never actually owned their coins — they only held the platform's promise to give them back.

How it works in Tegro Wallet

Tegro Wallet is non-custodial by architecture, not just in words. Here's what that means in practice:

• The 24-word recovery phrase is generated directly on your device when the wallet is created, and it's stored only there.
• The phrase and private key are encrypted with your PIN in the device's secure storage.
• Transactions are signed locally — the keys never leave the device and are never sent to any server.
• Tegro has no access to your funds and cannot move, debit, or freeze them.

The wallet talks to the TON network directly to show your balance and broadcast transactions, but the signature itself — the one action that actually moves money — always stays on your side. There is no intermediary between you and the blockchain who could interfere.

Freedom and responsibility — one package

Let's be honest: the non-custodial approach has a flip side. If the keys are only with you, then the responsibility for them is yours too. There is no "recover access" button, and no support team that can return your funds if the phrase is lost.

So a few rules are worth learning from day one:

• Write your recovery phrase down offline and keep it somewhere safe. Don't screenshot it and don't send it through a messenger.
• Never show the phrase to anyone. Tegro support will never ask for your recovery phrase or PIN — anyone who does is trying to scam you.
• Whoever gets those 24 words gets your money. Treat the phrase as if it were the funds themselves.

Now, back to the question we started with. What happens to your money if the platform shuts down tomorrow? In the custodial model — you wait, hope, and depend on other people's decisions. In the non-custodial model — you have 24 words in your hands, and access to your funds stays with you in any compatible wallet, no matter what happens to any particular service.

That is the freedom cryptocurrency was created for: money that only you control. Tegro Wallet gives you the tools to make it convenient and secure — while keeping the keys exactly where they belong. With you.
