How can I secure high-value wallets and DeFi positions?

[ed]

A: Advanced security involves multiple layers:

Hardware wallets (Ledger, Trezor) for cold storage.

Multi-signature wallets for shared control over large funds.

Dedicated vaults for staking or DeFi positions with daily withdrawal limits.

Segregate assets by risk: store long-term holdings cold, keep trading capital in smaller hot wallets.

Regularly review smart contract approvals on Ethereum, BSC, and other networks using Revoke.cash or similar tools.
