Self-custody
Direct control of the private keys required to authorize spending, with no custodian in the path.
SECSOURCE-LED TOPIC GUIDE
Learn private keys, seed backups, hardware wallets, multisig, threat models, privacy trade-offs and practical verification without relying on slogans.
Bitcoin ownership is control of signing keys, but secure custody is an operational system rather than a single device. This path starts with keys and wallet recovery, then adds hardware isolation, multisig, inheritance and privacy. Every design should be evaluated against a stated threat model and tested before meaningful funds depend on it.
