Custody vs Self-custody

Compare who controls keys, who handles recovery, and whether you can maintain safe backups.

After this guide, you should be able to:
  • Understand that assets are on-chain and wallets manage keys
  • Balance platform risk and user error
  • Build a recovery plan without exposing the phrase

Two responsibility models

Self-custody is not automatically safer. It exchanges some counterparty risk for key, device, backup, and signing risk.

  • Custody: a platform controls keys and you log into an account; recovery depends on its process, with platform and withdrawal risks.
  • Self-custody: you control keys and signatures; transfers do not need platform approval, but lost or exposed recovery data can permanently lose assets.

A recovery phrase is not a password

  • It may derive many accounts and private keys.
  • Legitimate support, airdrops, and upgrades do not need it.
  • Do not screenshot, cloud-upload, or enter it on an unknown site.
  • Hardware wallets reduce key exposure but cannot stop you approving a malicious transaction.

Before choosing

  • Know who currently controls the keys
  • Understand worst cases for both models
  • Recovery data is offline and retrievable
  • Backup and device are stored separately
  • Can verify address and transaction on-device
  • Test recovery and transfers with small value
  • Do not move everything based on a slogan

Three-question self-check

1. Are coins stored inside a wallet?

Asset records are on-chain; the wallet mainly manages keys and signatures.

2. Is self-custody always safer?

No. It reduces some counterparty risk but adds user and backup responsibility.

3. Can hardware wallets stop malicious approvals?

No. A confirmed malicious transaction can still cause loss.
