Request access deliberately
A provider request such as eth_requestAccounts can prompt a user to share account access. Never trigger it on page load or imply that a connection is required just to read this guide.
FEM / DEVELOPER NOTES / WALLETS
Wallets should make the network clear.
EVM applications commonly communicate with injected wallets through a provider interface. Ask for a connection only after a clear user action, and show the selected network before presenting a transaction for approval.
Check the active chain
The eth_chainId method reports the connected provider's chain ID. Compare it with a verified network specification; this guide intentionally supplies no FEM value.
Keep signing in the wallet
A web app should present the requested action clearly and let the wallet handle signing. Never ask users to paste recovery phrases or private keys into a website.
