Keeping control of your keys removes one intermediary, but it does not make every token, contract or signature safe.
Non-custodial means the service does not hold the private keys required to control your wallet. You connect a compatible wallet and authorize actions there. The label does not prove that a smart contract is audited, a token is genuine, a route is optimal or a signature is harmless.

| Key point | What it means | What to check |
|---|---|---|
| Keys | Remain in the connected wallet. | The interface should not request a seed phrase. |
| Connection | Exposes a public address and session. | Does not by itself transfer tokens. |
| Approval | Can grant a contract token-spending permission. | Must be reviewed separately from connection. |
| Signature | Authorizes the displayed message or transaction. | Can still be dangerous if the request is malicious. |
It does not certify the whole product or every contract.
Disconnecting and revoking an approval are different actions.
Key control helps only when authorizations are understood.
A non-custodial interface cannot independently sign a transaction from your wallet because it does not control the private keys. The wallet is the signing environment. That distinction matters, but it describes custody only—not every aspect of product security.
A connection usually lets a site see the selected public address and request signatures. A token approval is an on-chain permission for a specific spender contract. Disconnecting a site does not automatically revoke permissions that are already recorded on-chain.
Wallet prompts can authorize transactions, token approvals or messages used by applications. Check the network, destination, requested asset and permission. Reject unexplained prompts, especially when a site creates urgency or asks you to ignore wallet warnings.
Non-custodial does not mean risk-free, permissionless on every network, anonymous, audited or immune to front-end compromise. It also does not guarantee the best quote. Each of those claims needs separate evidence.
Bookmark the official domain, use a dedicated wallet for experimentation, keep seed phrases offline, verify contracts, limit allowances where practical and periodically revoke permissions you no longer need. Hardware wallets can add signing isolation but still require you to read the request.
Latin Link is a non-custodial liquidity aggregator interface, not a wallet and not a custodian. You connect a compatible self-custody wallet and authorize transactions there. Latin Link uses OpenOcean routing to consider eligible liquidity sources; the displayed route is a time-sensitive estimate, not a guarantee of the best possible execution.
It does not control your keys, but a specific front end or route can become unavailable. You may still interact through other compatible tools.
Connection alone is limited, but it enables signature requests. Verify the domain and read every later prompt.
No. On-chain approvals remain until they expire, are spent or are revoked with an on-chain transaction.
No. Public blockchains expose addresses and activity, and interfaces may have their own data practices.
No. Latin Link is a non-custodial liquidity aggregator interface. A compatible external wallet manages your keys and signs the transaction.
This guide is educational and is not financial, investment, legal or tax advice. Tokens, smart contracts, approvals, wallets and blockchain networks involve risks, including irreversible loss. Verify current product support and transaction details before signing.
Open the swap and review the network, tokens, amount and slippage. When shown, compare the route, costs and minimum received; confirm everything in your wallet before signing.
