Self-custody vs custody
The practical difference is who can authorize a transaction—and who can restore access when something goes wrong.
With self-custody, you control the keys and sign transactions from your wallet. With custody, a provider controls the keys and updates or moves assets on your behalf. Neither model is automatically safe: self-custody shifts security and recovery to you, while custody adds provider, access and counterparty risk.
The details to check before you decide.
Swap now!| Key point | What it means | What to check |
|---|---|---|
| Private keys | Held by the user in self-custody. | Held or controlled by the custodian. |
| Transaction approval | User signs in the wallet. | Provider processes an account instruction. |
| Recovery | Seed phrase or wallet recovery method. | Provider account-recovery process. |
| Primary exposure | Key loss, phishing and unsafe approvals. | Provider failure, freezes, breach and account access. |

Recovery differs
Self-custody backups and provider recovery solve different problems.
Risk is not removed
It shifts between user security and provider dependency.
Custody is about control, not interface design
A polished app can be custodial or self-custodial. The deciding question is who can produce the signature that moves the assets. If the provider can move funds without a signature from your own wallet, the provider is part of the custody model.
What self-custody gives you
Self-custody removes the need to ask a central service to approve a withdrawal. You can interact directly with compatible smart contracts and networks. That control is paired with responsibility: a compromised seed phrase or malicious signature can result in irreversible loss.
What custody can provide
Custodial services may offer familiar passwords, assisted recovery, internal transfers and customer support. Those conveniences depend on the provider remaining solvent, secure and willing or legally able to process access and withdrawals.
Recovery is the sharpest trade-off
A self-custody wallet provider generally cannot reconstruct your secret recovery phrase. Backups must be accurate, offline and protected from disclosure. A custodian can reset account credentials, but that recovery channel can itself be targeted by attackers.
A useful decision test
Ask who holds the keys, who signs the transaction, whether withdrawals can be paused, how recovery works and what happens if the company disappears. Use those answers—not the marketing label—to identify the custody model.
Where Latin Link fits
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.
Common questions about this topic.
Swap now!Is a self-custody wallet an exchange?
No. A wallet manages keys and signs transactions. It may connect to exchanges or aggregators, but it is a different product role.
Can a self-custody provider recover my seed phrase?
Normally no. Anyone who has the seed phrase can control the wallet, so genuine providers should not ask for it.
Does custody always require KYC?
Not as a definition. Custody describes key control; identity requirements depend on the service and jurisdiction.
Can I use both models?
Yes. Some users keep different assets or activities in different setups, but each transfer and service adds its own risks.
Is Latin Link a wallet?
No. Latin Link is a non-custodial liquidity aggregator interface. A compatible external wallet manages your keys and signs the transaction.
