A beginner guide to browser wallets, self-custody basics, DEX flow, token approvals,
and the operational habits that reduce avoidable mistakes on-chain.
Shaped by official wallet and DeFi documentation, but written originally.
Lesson 1
What a browser wallet actually does
A wallet does not “hold” coins in the same way a bank app holds money. It manages
keys and permissions that allow you to interact with blockchain accounts. That is
why protecting your recovery phrase matters more than memorizing the user interface.
Lesson 2
DEX flow is simple, but approvals create risk
A decentralized exchange lets you swap tokens directly from your wallet, but many
first-time users do not understand approvals. Approvals give contracts permission to
move tokens, which is why revoking stale approvals and checking contract addresses is
part of safe wallet behavior.

Execution Flow
The baseline wallet checklist
The full guide uses a repeatable safety sequence before every connection.
Confirm the domain from an official source before connecting the wallet.
Check the network, token symbol, and contract details before approving anything.
Review the prompt slowly and reject transactions that do not match the intended action.
Revisit approvals periodically and keep high-value holdings separated from active wallets.
