Networks
Learn the system beneath the interface.

Bitcoin, Solana, and Ethereum do not share an identical account model, execution process, or asset representation. A symbol on a screen can conceal those differences. This collection asks where an asset is recorded, which network accepts the transaction, and what extra systems a position depends on.

Read the Bitcoin guide to distinguish native BTC from representations used elsewhere. The Solana guide focuses on identifiers, account behavior, fee reserves, and delegation. The Ethereum guide explains the full fee journey, including approvals and Layer 2 entry and exit. Each starts from its own network context rather than treating a familiar wallet interface as proof of equivalence.

Use these articles to make a network-specific checklist before exploring an application. Record the chain, asset identity, fee asset, destination, and withdrawal path. Bridging or switching networks deserves a fresh review, not merely a different network selection in the same workflow. The articles are conceptual guides rather than live network-status reports.
