Before you begin: DApps and connections
Interfaces can look similar while pointing to different networks, contracts and account permissions. Visual similarity is never enough to establish that two actions are equivalent. For Web3 Guides, start with DApps and connections, then place signatures inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.
Before acting, identify the account in use, the target network, the asset or contract involved and the on-chain action expected to occur. When approvals is relevant, review fee source, request details and confirmation state. When working with NFTs, prefer verifiable on-chain information over a label shown by one interface.
After the action, keep enough information to check the result again, such as contracts, the network name, destination address or contract address. On-chain transactions generally cannot be reversed by a wallet acting alone. Third-party DApps and smart contracts carry their own risks, and a wallet connection does not make every request trustworthy.
Using DApps as an example, separate what you see into three layers: interface presentation, the wallet request, and the verifiable on-chain result. The interface explains context, the wallet request defines what will be signed or sent, and the chain records what actually happened. If those layers do not agree, stop and verify the network, address, contract or transaction state before continuing.
A practical path for signatures
Understanding this topic starts with the relationship between the account, the selected network and the permission being requested, not with memorizing where a button sits. For Web3 Guides, start with DApps and connections, then place signatures inside the actual workflow.

Checking approvals and NFTs
On-chain activity is a sequence of independent decisions. A wrong network, address or permission can change the outcome, so the workflow should be understood before action. For Web3 Guides, start with DApps and connections, then place signatures inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.

After the action: contracts and security review
A wallet connects a user to blockchain networks, but it cannot make every risk decision on the user’s behalf. Critical details still need to be reviewed directly. For Web3 Guides, start with DApps and connections, then place signatures inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.
