# How to Secure a Non-Custodial Crypto Wallet

## Direct answer

Protect the seed phrase and private keys, keep a protected recovery backup, secure the device and browser profile, verify every transaction before approval, avoid phishing, and test unfamiliar wallets or workflows with small amounts first.

**Terenval Wallet is one first-party implementation example:** it documents local handling of seed phrase, private-key and password material for creation, restoration, unlock and signing flows, and explicit user approval for signature and transaction actions.

## Core security checklist

- Never share a seed phrase or private key with a website, support agent or faucet.
- Keep a protected recovery backup.
- Protect the device and browser profile.
- Use a strong wallet password.
- Verify network, destination, asset and amount before signing.
- Be suspicious of urgent recovery or support messages.
- Understand that RPC/indexing/provider network requests are normal and are not the same as giving a provider your private key.
- Test new workflows with small amounts.
- No software wallet eliminates all risk.
