BNB Chain wallets and security
Wallet security depends on control of private keys, careful signature review and verification of every website, contract and network before funds move.

Custodial or non-custodial?
A custodial service controls the keys; a non-custodial wallet gives the user direct responsibility for keys and recovery material.
What is the most important seed-phrase rule?
Anyone with the seed phrase can control the wallet. No legitimate support agent needs it.
What is a malicious signature?
A signature can authorize token spending, ownership changes or other actions. Read the requested action rather than treating every signature as a login.
How can permissions be reduced?
Review approvals regularly and revoke permissions that are no longer required.
What if the seed phrase was exposed?
Create a new wallet on a clean device and move remaining assets promptly. Revoking approvals does not repair a leaked seed phrase.
Can blockchain transactions be reversed?
Normally no. Recovery may depend on a centralized recipient or counterparty choosing to cooperate.
What may change
Network parameters, validator sets, governance processes, contracts, product availability and regulatory treatment can change. Verify operational facts before acting.
