Contract Rules
A practical approach to contract rules
Understanding “Contract Rules” starts with the real task described on this Smart Contract Interaction page. The relevant concepts include smart-contract addresses, function calls, state changes, events, gas and permissions. The goal is to separate interface hints from identifiers and states that can be independently checked through the active network, a block explorer, or the wallet itself.
Before confirmation, read or record the non-sensitive details that matter: network, contract address, method, parameters, value transfer, permission scope and transaction result. This creates a reliable troubleshooting trail if a transaction is pending or an interface displays an error, without resorting to repeated signatures, repeated submissions or disclosure of recovery material.
The main risk boundary includes unknown code, upgradeable-contract changes, malicious functions, expanding permissions and irreversible execution. Knowledge from imtoken can explain how to inspect a request, but it cannot guarantee a third-party DApp, smart contract, bridge or service. Users should make a separate judgment about the specific counterparty and should never provide recovery material.
Contract Addresses
A practical approach to contract addresses
For “Contract Addresses,” the useful skill is not memorizing where a button appears. It is knowing the order of decisions around smart-contract addresses, function calls, state changes, events, gas and permissions: identify the object, confirm the network and account context, understand the requested change, and decide what evidence will show that the action completed as intended.
Decide whether to continue only after checking network, contract address, method, parameters, value transfer, permission scope and transaction result. When a wallet, DApp, exchange interface and explorer appear to disagree, first resolve the network and on-chain object instead of assuming that every interface is referencing the same chain or asset.
Typical risks include unknown code, upgradeable-contract changes, malicious functions, expanding permissions and irreversible execution. No “absolute safety” claim can remove these possibilities. A more realistic approach is to minimize secret exposure, keep approvals scoped to the intended use, verify the target and remove connections or permissions that are no longer needed.

Read vs Write Operations
A practical approach to read vs write operations
“Read vs Write Operations” is connected to the steps before and after it, so control, network context and on-chain outcome should be considered together. With smart-contract addresses, function calls, state changes, events, gas and permissions in view, a user can distinguish a read-only request from a connection, signature, approval or transaction instead of treating every wallet prompt as equivalent.
A practical review can consistently cover network, contract address, method, parameters, value transfer, permission scope and transaction result. If one of these does not match the intended action, stop and re-check the source and destination before submitting again. Seed phrases, private keys and verification codes are never normal troubleshooting fields and should not be shared.
Include unknown code, upgradeable-contract changes, malicious functions, expanding permissions and irreversible execution in routine maintenance instead of waiting for an incident. Review old approvals, keep the device environment trustworthy, verify domains and networks, and retain the public transaction information needed to independently check what happened.
Approvals and Contract Calls
A practical approach to approvals and contract calls
Names and icons can look familiar in a “Approvals and Contract Calls” workflow without referring to the same on-chain object. For smart-contract addresses, function calls, state changes, events, gas and permissions, verifiable identifiers are more dependable than visual similarity, particularly when several EVM-compatible networks or similarly named assets are involved.
An actionable checklist should include network, contract address, method, parameters, value transfer, permission scope and transaction result. Review intent before the prompt, read the prompt during confirmation, and verify the outcome afterwards with a transaction hash, public address, contract address or network state when applicable. These three checkpoints are more useful than a generic warning.
Problems in this area often come from unknown code, upgradeable-contract changes, malicious functions, expanding permissions and irreversible execution. If the source is suspicious, the target is unclear or the request exceeds the task at hand, decline it and investigate. On-chain transactions generally cannot be unilaterally reversed by a wallet, so verification is more important than speed.

Failure Checks
A practical approach to failure checks
Finishing “Failure Checks” should not mean stopping at a success message. Use smart-contract addresses, function calls, state changes, events, gas and permissions to check the conditions before submission, the request at confirmation time and the resulting state afterwards. That makes the workflow repeatable and easier to troubleshoot.
For a first attempt, rehearse the workflow using non-sensitive, verifiable information such as network, contract address, method, parameters, value transfer, permission scope and transaction result. Understanding what each field represents before an irreversible action or permission change is safer than mechanically copying a sequence of clicks.
Finally, distinguish “submitted” from “confirmed.” unknown code, upgradeable-contract changes, malicious functions, expanding permissions and irreversible execution can affect the actual outcome or permission exposure. Use the relevant network record, explicit approval state and destination-service support information rather than unverified assurances as evidence.
