Privacy Policy

Version 1, 12 November 2026.

1. What this covers

This policy covers the Trestly web app, the kUSDT Wallet browser extension and the Trestly documentation (together, "the interface"), published by Trestly ("we", "us"). It says what information the interface handles, where it goes, and what we do with it. The short version: we have no accounts, no analytics, no advertising and no tracking, and your keys never leave your device.

2. Your keys and your wallet

  • The kUSDT Wallet makes your keys on your device. Your recovery phrase is stored in your browser's extension storage, encrypted with the password you choose. While the wallet is unlocked it is held in the browser's session memory only, and it is cleared when the wallet locks.
  • Your recovery phrase, your keys and your password are never sent to us or to anyone else. We cannot see them, and we cannot recover them for you.
  • The wallet also keeps, on your device only: your settings (networks and the nodes you chose), the history of your own transactions, the list of websites you connected it to, and the version of the Terms of Service you accepted.

3. What the interface sends, and to whom

To show your balances and send your transactions, the interface talks to the networks it works with. These requests carry your public addresses and the transactions you sign, and, like any internet request, your IP address.

  • Kaspa nodes: by default a node of the public Kaspa node network, found through its public resolvers, or a node you set yourself.
  • Ethereum and BNB Chain nodes: public RPC providers (for example PublicNode, dRPC, Tenderly and BNB Chain's own nodes), or the ones you set yourself.
  • The Trestly bridge: our bridge API and the bridge monitor's status, which answer what the bridge holds, what it has minted and paid, and whether it is running.
  • Your other wallets, if you use them with the web app: browser wallets such as MetaMask, and WalletConnect, whose relay passes messages between the web app and your phone wallet.

Each of these providers runs under its own privacy policy. Blockchain transactions are public and permanent: anyone can see the addresses and amounts of a transaction once it is on a blockchain, and nobody, including us, can remove them.

4. Websites you connect the wallet to

When you connect the kUSDT Wallet to a website, that website learns the addresses you approve, and the requests you approve, such as a transfer or a swap. It learns nothing else from the wallet. You can disconnect a website at any time in the wallet's settings.

5. The web app

The web app runs in your browser. It remembers a few things in your browser's local storage: your settings, that you accepted the Terms of Service, and public records of your own transfers so that you can follow them. It sets no tracking cookies and uses no analytics. You can clear this storage in your browser at any time.

6. Our servers

Our websites and the bridge API are served through Cloudflare, which handles every request on its way to our servers. Cloudflare and our servers see the IP address of each request. We use it to limit how many requests one client can make, to keep the service running and to protect it from abuse. Our servers may keep technical logs (the time, what was requested, errors) for the same reasons, only as long as needed for them. We do not build profiles of users, and we do not sell or share any information for advertising.

7. The bridge

When you bridge, your deposit, your burn of kUSDT, and the address you send to are on public blockchains. The bridge's signers, coordinator and monitors read them there to mint and pay. Before a payout, the bridge checks the receiving address against the token's public blocklist, and it pays nothing to a blocked address. The bridge keeps no information about you beyond what is on the blockchains.

8. Children

The interface is not meant for children. Do not use it if you are under the age at which you may use such services where you live.

9. Your choices and your rights

You can use the interface without giving us any personal information. You can set your own nodes and RPC providers in the wallet, clear the web app's local storage, and remove the wallet, which deletes everything it stored on your device. If the law where you live gives you rights over personal data, or you have a question about this policy, contact us.

10. Changes to this policy

We may change this policy. The version and date are shown at the top. A change that affects how your information is used is announced on the website before it applies.
