Public chain basics
Public chain basics is a distinct part of understanding Network Guides. Network guides explain public chains, EVM, Layer 2, gas, block confirmation and explorers, helping users select the right network and verify transaction state in a multi-chain environment. Learning addresses, networks, gas and transaction hashes before moving into DApps, approvals and contracts makes interface prompts easier to interpret. The goal is not memorizing terminology but being able to verify what is happening during a real workflow.
In practice, do not rely on interface color, icons or labels alone. Cross-check verifiable details such as the active network, public address, transaction hash, contract address and approval target. Before any action that changes onchain state, read the request and confirm the amount, network and destination.
If something looks wrong, stop signing or resubmitting transactions until the situation is understood. Keep non-sensitive details such as the transaction hash, network name and public address for troubleshooting, but never share a seed phrase, private key or verification code. Onchain transactions are generally not reversible by a wallet provider, so preventive checks matter more than recovery promises.

- Confirm the active network before sending or approving.
- Compare the full destination or contract details.
- Keep recovery material offline and private.

Security and risk reminder
Blockchain transactions are generally irreversible by a wallet provider. Third-party DApps and smart contracts can contain technical or business risks. Review every signature and approval independently, and consider revoking permissions you no longer use.
