1k is built to need as little about you as possible. This is what we do handle.
1. No accounts
1k has no sign-up, no email list and no passwords. You connect a wallet; we see its public address while you use the site.
2. What we process
- Wallet addresses and transactions. Used to show balances, positions and history. Blockchains are public: anyone can see these, with or without us.
- Proof ledger. When you trade through 1k, we record the transaction (wallet, tokens, amounts, venue, hash) after checking it onchain, and show it on the public Proof page.
- Transfer ledger. Cross-chain transfers you send through 1k are recorded (wallet, route, hashes) so your history can show their status.
- Request logs. Our servers and hosting provider log requests (IP address, time, page or API call) for security and to keep the service running. We keep them only as long as needed for that.
- Settings in your browser. Your theme, chain, slippage and watchlist are stored in your own browser (local storage), not on our servers.
3. No ads, no tracking
We do not use advertising or cross-site tracking cookies and do not sell data.
4. Who else sees it
To quote and build a trade we send the tokens, amount and, when needed, your wallet address to the venues and bridges we compare (such as KyberSwap, LI.FI, 0x, Relay, Jupiter, Uniswap, Metric, Sushi, Odos, Velora, Bebop, DODO, Raydium, deBridge and Across). Market data comes from Hyperliquid, DexScreener and GeckoTerminal; company data from SEC EDGAR and news sources. Blockchain reads go through RPC providers. If you connect with WalletConnect, Reown relays the session. Each of these handles data under its own policy.
5. Your choices
You can use 1k without connecting a wallet, clear your browser settings at any time, and ask us to remove ledger entries tied to your wallet where we can. Data already on a blockchain cannot be erased by anyone.
6. Changes
We will update this notice when what we collect changes; the date at the top shows the latest version.
