Moving to Self-Custody

Moving from exchange custody to self-custody is a deliberate risk transfer: you replace counterparty trust with personal responsibility for keys, backups, and transaction accuracy. The goal is not to abandon CeFi entirely — most users still need fiat ramps — but to right-size on-platform exposure and keep long-term holdings under keys only you control.

Hardware wallets isolate signing keys from internet-connected devices. Popular options include Ledger and Trezor; each supports major chains through companion apps. Write seed phrases on durable offline media — never store them in cloud notes, photos, or password managers synced online. Consider multisig or social recovery for large holdings where single-device loss would be catastrophic.

Tax and operational planning still matter after exit. On-chain activity is visible to analytics firms; you remain responsible for reporting. Many users adopt a split model: regulated exchange for fiat in/out and active trading, cold storage for core positions. Revisit the split after major life events, portfolio growth, or any exchange policy change that affects your comfort with counterparty risk.
