Getting started technically.
WHAT TO LEARN FIRST
How the network you target actually works Its programming language The development tooling How to read a block explorer
WHY THE EXPLORER SPECIFICALLY
It is the primary diagnostic tool, showing what actually happened.
WHAT TOOLING PROVIDES
Local networks for development Testing frameworks Deployment scripts Contract verification
WHAT A LOCAL NETWORK PROVIDES
Instant blocks, free transactions, and controllable state.
WHAT TEST NETWORKS PROVIDE
Realistic conditions, with valueless assets.
WHAT TO DO BEFORE ANY DEPLOYMENT
Extensive testing on both.
WHAT CONTRACT VERIFICATION IS
Publishing source code matching the deployed bytecode.
WHY IT MATTERS
Users cannot assess an unverified contract.
WHAT TO ALWAYS DO
Verify contracts you deploy.
WHAT TO LEARN ABOUT COSTS
How to estimate them, and how to reduce them.
WHAT FRONT-END DEVELOPMENT REQUIRES
Wallet connection libraries Reading contract state Constructing and submitting transactions Handling pending, confirmed and failed states
WHAT TO HANDLE CAREFULLY
Users rejecting transactions Network congestion Transactions pending for long periods
WHAT TO SHOW USERS
Exactly what they are about to sign.
