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
Use knowledge for a check, not an impulse trade
Review wallet, phrase, and private-key terms
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.
