Start hereHow Does Crypto Wallet Recovery and Inheritance Work?
Wallet recovery is the set of mechanisms that restore signing authority after loss: a device failing, a phrase burning, an owner forgetting, or an owner dying.

Part 2How to Keep Your Crypto Safe in 2026: The Complete Guide
Keeping crypto safe means controlling who can move your assets and making sure that someone is always you. In practice it is five disciplines working together: securing the accounts around your crypto with strong authentication, choosing custody so no single secret or company can lose everything, verifying what you sign before you sign it, limiting what strangers can learn abo…
Part 3The State of Crypto Self-Custody 2026
The State of Crypto Self-Custody is a periodically updated research report that measures how crypto holders custody their assets: the share of value held in holders' own keys versus exchanges, custodians and funds, the number of people involved, the events that move them between models, and the technology they use.
Part 4Ways to Hold Your Keys: Hardware, Software, and MPC Compared
A key storage model is the arrangement that decides where a wallet's signing authority lives and what must be compromised, lost or coerced for assets to move. Software wallets hold keys on a connected device, trading safety for convenience. Hardware wallets isolate keys in a dedicated device designed to sign internally and keep key material inside.
Part 5What Is a Seed Phrase, and Why Is It a Single Point of Failure?
A seed phrase, also called a recovery phrase, is a sequence of words, twelve to twenty-four under the BIP39 standard, that encodes the entropy from which a wallet mathematically derives its private keys.
Part 6What Is Multisig, and How Does It Remove Single Points of Failure?
A multisignature wallet is a custody arrangement that requires a threshold of independent keys, m of n, to authorise any transaction, enforced by the blockchain itself through a script or smart contract.
Part 7Who Holds Your Crypto? Custodial vs Self-Custody vs MPC
A custody model is the arrangement that decides who controls the key able to move your crypto. Custodial services hold keys on your behalf, so you rely on the company. Single-key self-custody puts one key, and its seed phrase backup, entirely in your hands.
