What Do Custodial and Non-Custodial Mean?

Custodial: Someone else holds the private keys on your behalf. Exchanges like Paribu, BTCTurk, and Binance TR use this model. You see a balance in your account but the assets are actually under the exchange's control.

Non-custodial (self-custody): You hold the private keys. Wallets like KriptoK use this model. You genuinely own your funds.

What's the Practical Difference?

Think of a bank: when you open an account, the money feels like yours. But if the bank becomes insolvent, freezes accounts, or a financial crisis hits, you may not be able to access it. Crypto exchanges work the same way.

In self-custody, the vault is yours. As long as you hold the private key, no external force can reach your funds.

Advantages of Custodial

  • Easy to use; account recovery if you forget your password
  • Can buy and sell using local currency (TRY)
  • 24/7 integration with Turkish banks
  • Suitable for beginners

Advantages of Self-Custody

  • True ownership: no one can freeze your funds
  • No exchange insolvency risk
  • Access to DeFi, swaps, NFTs, and onchain features
  • No withdrawal limits
  • Privacy: no personal information required

The Risk

Self-custody's only risk is seed phrase management. If you lose your seed phrase, you lose your crypto permanently. The responsibility is entirely yours.

Which Model Is Right for You?

The smartest approach is using both: buy crypto with TRY on an exchange, then transfer to a self-custody wallet. You combine the convenience of buying with genuine ownership.
