Custodial vs Self-Custody
Custody choice is a swap between counterparty risk you cannot control and operational risk you can.

Self-custody removes the counterparty entirely and makes backups, device hygiene and approval discipline your job.

| Failure mode | Custodial: insolvency, freeze, hack | Self-custody: lost seed, malicious signature |
| Recovery | Custodial: account recovery exists | Self-custody: seed backup or nothing |
| Access to DeFi | Custodial: limited to what the provider offers | Self-custody: any contract on the chain |
