Wallet, network, Web3 and security questions
No. You should keep recovery secrets yourself and never send them to anyone or enter them into an ordinary web page.
At minimum, verify the recipient address, destination network and amount. For tokens, also confirm the token contract and expected network fee.
Gas is the network resource pricing mechanism used for on-chain transactions and contract calls. Cost varies with network conditions and operation complexity.
A transaction hash is a unique lookup reference that can be used in a block explorer to check status, block data and related addresses.
Not necessarily. Account connection, message signing, transaction signing and token approvals are separate requests and should be reviewed separately.
Permissions can remain active after you stop using a DApp. Reviewing the spender and allowance helps you identify approvals you may want to revoke.
No. Similar address formats do not mean the networks are interchangeable. Confirm both sides support the same network and asset.
Layer 2 systems extend base-layer capacity using different mechanisms. Bridging, confirmation and fee behavior can vary by network.
Usually not. Once a network confirms a transaction, a wallet generally cannot reverse it unilaterally.
Check the domain source, contract address, request details and permission scope. Stop if a page requests recovery secrets or unusually broad permissions.
Avoid sensitive operations on untrusted networks, verify the domain carefully and keep your system and browser updated.
It is generally a poor choice because screenshots may sync to cloud services or be readable by other software. Controlled offline storage is preferable.
No. Rewards can change with protocol rules, validator status, service fees and other conditions, while digital asset prices can also fluctuate.
PoS networks require validators to follow protocol rules. Downtime or protocol-defined faults can reduce rewards or result in penalties.
Not always. Exit and withdrawal can be affected by protocol queues, network conditions and service processes.
Stop repeating the action, save the transaction hash, network and relevant addresses, then verify the on-chain state with a block explorer.
A note on support
Do not send seed phrases, private keys or verification codes when asking for help. Use transaction hashes and public addresses where appropriate to describe an on-chain issue.
