What is Self-custody?
Holding your own private keys in your own wallet, with no company in between. Total control, total responsibility — the trade-off at the heart of crypto.
Self-custody means holding your own private keys in your own wallet — no exchange, no company, no one between you and the blockchain. It's crypto's founding promise made literal: assets that can't be frozen, seized by a failing platform, or lent out behind your back. The FTX collapse converted a generation to the idea overnight.
The unromantic second half: you are now the security department, the backup system and the estate plan. No password resets, no fraud reversal, no support line — every protection a custodian provided now either exists because you built it or doesn't exist. The honest pattern for most people is graduation, not absolutism: exchange accounts for buying and small balances, self-custody for savings once the stakes justify the discipline. The migration checklist is the step-by-step.

FAQ
At what point should I move to self-custody?
A workable rule: when your holdings exceed what you'd tolerate losing to a platform failure, the discipline of self-custody starts paying for itself. The number is personal; the existence of a threshold isn't.
Is self-custody safer than an exchange?
It removes counterparty risk and adds operator risk — you. For careful people it's the stronger position; for people who'll photograph their seed phrase "just temporarily", it demonstrably isn't. Know which user you are before the stakes decide for you.
