Non-Custodial Wallets: Security Models, Recovery, and Web3 Use
Summary
The document explains how non-custodial wallets give users control of private keys and contrasts them with custodial services. It distinguishes hot wallets, which suit frequent access, from cold storage, which is presented as a better fit for long-term holdings. The choice depends on trading frequency, security needs, and portfolio size, while self-custody makes the user responsible for protecting keys and recovery methods.
It surveys alternatives to seed phrases, including multi-party computation and hardware wallets, and describes wallet features such as two-factor authentication, biometrics, encryption, and third-party audits. Wallet integrations can also provide access to decentralized applications, NFTs, staking, and multiple blockchain networks. The document recommends hardware storage for long-term assets, enabling extra account protections, and keeping wallet software updated. It offers general security guidance rather than comparative security evidence or a threat model, and notes that privacy-focused features may face regulatory pressure.
Key ideas
- Non-custodial wallets put private-key control and recovery responsibility with the user.
- Hot wallets favor convenient access, while cold wallets are suited to longer-term storage.
- Multi-party computation and hardware devices are presented as alternatives to relying on a seed phrase alone.
- Wallets increasingly combine asset storage with access to decentralized applications, NFTs, and staking.
- Security features and good user practices can reduce risk, but privacy features face regulatory challenges.
