Self-Custody
Self-custody is the practice of holding your own cryptographic keys rather than delegating custody to an exchange or custodian. In a self-custody wallet, no third party can freeze, seize, or lose your funds because no third party holds the keys.
How it works
The wallet generates keys locally, signs transactions locally, and broadcasts them to the chain. Nothing about ownership depends on a company remaining solvent, honest, or online. Loss of the keys means loss of the funds; there is no reset, no support line, and no chargeback. Modern self-custody wallets ship recovery mechanisms — Shamir sharding, social recovery, hardware pairing — that make key loss survivable without reintroducing a custodian.
Why it matters
Self-custody is the original point of cryptocurrency: bearer instruments that settle without an intermediary. Exchange failures — FTX, Mt. Gox, Celsius — repeatedly demonstrate the cost of trusting a custodian. Self-custody accepts responsibility in exchange for control: users cannot lose funds to another entity’s bankruptcy, sanctions, or hack.
Related concepts
- Non-Custodial Wallet — A non-custodial wallet is a wallet in which the user, not a third party, holds the private keys.
- Custodial Wallet — A custodial wallet is a wallet in which a third party holds the private keys on the user’s behalf.
- Seed Phrase — A seed phrase — also called a recovery phrase or mnemonic — is a human-readable list of 12 or 24 words that encodes the entropy behind every private key in a wallet.
- Hardware Wallet — A hardware wallet is a dedicated physical device that stores private keys in tamper-resistant hardware and signs transactions on-device.
Frequently asked questions
Is self-custody the same as non-custodial?
They are used interchangeably. Both mean the user holds the keys.
What if I lose my phone?
A self-custody wallet is recoverable from its backup — Shamir shards in Veyrnox’s case. Without a backup, the funds are lost.
Do I still need to file taxes?
Yes. Self-custody does not change your tax obligations; on-chain activity remains reportable in most jurisdictions.
In Veyrnox
Every Veyrnox tier is self-custody. Free removes the seed phrase from the UI while preserving user-only control of keys; Safety Plus adds Shamir sharding and Coercion Resistance without introducing a custodian. See no seed phrase wallet for the architecture.
