Public Chains
Nodes, blocks, transactions, confirmations and explorers form the foundation for reading on-chain state.
Why networks remain separate
Network selection determines where a transaction is submitted. Even when address formats look alike, chain state, gas, chain IDs and application ecosystems remain separate. In the context of Public Chains, the practical goal is to understand what the wallet is showing, what the network is recording, and which details must be verified before you approve an action.
A useful check is to separate interface information from on-chain facts. Review the active network, address, transaction hash, contract or permission scope as relevant, and avoid assuming that a familiar symbol or screen guarantees the intended result.
Confirmations and on-chain verification
A block explorer can help verify transaction hashes, block heights, confirmation counts and contract addresses, making it a key tool for checking on-chain facts. In the context of Public Chains, the practical goal is to understand what the wallet is showing, what the network is recording, and which details must be verified before you approve an action.

Practical verification points
Gas, contracts and network parameters
Cross-chain and cross-layer transfers introduce bridges, contracts and additional waiting steps, so ordinary same-chain transfer assumptions do not always apply. In the context of Public Chains, the practical goal is to understand what the wallet is showing, what the network is recording, and which details must be verified before you approve an action.
A useful check is to separate interface information from on-chain facts. Review the active network, address, transaction hash, contract or permission scope as relevant, and avoid assuming that a familiar symbol or screen guarantees the intended result. A public chain is maintained by distributed nodes that share state. A submitted transaction propagates through the network, may be included in a block, and gains further confirmations as later blocks are added. A block explorer reads public chain data; it does not execute the transaction.

- Verify the active network and destination before confirming.
- Treat seed phrases and private keys as secret credentials.
- Review DApp, signature and approval requests independently.
