Keep seed phrases and private keys under your own control; no one should ask for them; review each transfer, signature and approval separately.
Seed phrases and private keys
This section focuses on seed phrases and private keys and how it affects a practical wallet, network or Web3 workflow.
For seed phrases and private keys, begin by identifying the active network, the exact address or contract involved, and the result you actually intend to achieve. Fees, confirmation speed and contract behavior change with network conditions, so wallet estimates should be interpreted in the context of the active chain. This turns an interface prompt into information that can be independently checked instead of relying on a name, icon or single status label.
A practical review of seed phrases and private keys separates origin, target, permission or value, and network state. Connections, message signatures, transaction signatures and token approvals are distinct requests; review the spender, allowance and expected effect separately. If a contract is unfamiliar, an allowance is unexpectedly broad, the network is wrong, or the result does not match your intent, stop and verify the transaction hash, contract address or block state before continuing.
More broadly, seed phrases and private keys rarely stands alone. It usually connects to at least one of the following: an address, an active network, gas, a transaction hash, a DApp request or validator state. Reading those pieces together reduces errors caused by choosing the wrong chain, misunderstanding a permission or misreading a pending state.
- Verify the active network, address or contract target
- Keep a transaction hash or other public data that can be independently checked
- Never provide a seed phrase, private key or verification code to anyone
Approval security
This section focuses on approval security and how it affects a practical wallet, network or Web3 workflow.
A practical review of approval security separates origin, target, permission or value, and network state. Connections, message signatures, transaction signatures and token approvals are distinct requests; review the spender, allowance and expected effect separately. If a contract is unfamiliar, an allowance is unexpectedly broad, the network is wrong, or the result does not match your intent, stop and verify the transaction hash, contract address or block state before continuing.
Understanding approval security also means considering what remains true after you confirm. Transaction hashes, block height, contract addresses and event logs provide useful verification points for distinguishing interface delays from actual on-chain state. On-chain transactions generally cannot be reversed by a wallet alone, and a DApp connection is not the same as an approval. The confirmation button is only the final step; the important work happens before it.

Phishing recognition
This section focuses on phishing recognition and how it affects a practical wallet, network or Web3 workflow.
Understanding phishing recognition also means considering what remains true after you confirm. Connections, message signatures, transaction signatures and token approvals are distinct requests; review the spender, allowance and expected effect separately. On-chain transactions generally cannot be reversed by a wallet alone, and a DApp connection is not the same as an approval. The confirmation button is only the final step; the important work happens before it.
Security around phishing recognition should be considered together with seed phrases, private keys, device conditions and permission management. Transaction hashes, block height, contract addresses and event logs provide useful verification points for distinguishing interface delays from actual on-chain state. A legitimate workflow does not require sending recovery secrets or verification codes to another person or entering them into an unknown webpage.
