Network basics
Put each action on the right chain.

Networks are more than alternative routes to the same experience. They define how transactions are recorded, how fees are paid, and how assets are identified. Applications may hide these differences behind similar buttons, so the first task is to make the network explicit.

This collection brings together the Bitcoin, Solana, and Ethereum guides. Read the one closest to your question, then use the others to identify assumptions that do not travel cleanly between systems. The Bitcoin article highlights representations and trust layers; the Solana article focuses on operational account and transaction checks; the Ethereum article follows costs through approvals and Layer 2 workflows.

A useful outcome is a network-specific note with asset identifiers, the native fee asset, transaction-status checks, and the intended exit route. Do not treat a common ticker or familiar interface as evidence that every step is equivalent across chains. These articles explain concepts and research questions, not real-time fee quotes or transaction guarantees.
