## What it is
A command-line tool (npm package 'starkscan') that verifies Cairo smart contract ABIs on the Starkscan block explorer for Starknet. Verification ensures transactions and events are decoded correctly and lets users trust contract information when interacting on-chain.

## Use cases
- verify a cairo smart contract on starknet
- publish verified contract source on a block explorer
- make contract transactions and events decode correctly on starkscan
- confirm a starknet contract abi is not misleading
- let users safely run read and write operations on my contract
- verify contract abi from the terminal with npx

## When to choose
- you deployed a Cairo contract on Starknet and want it marked verified on Starkscan
- you want decoded, human-readable transactions and events for your contract
- you want to reduce security risk for users interacting with your unverified contract

## When to avoid
- you need contract verification on Ethereum or EVM chains rather than Starknet
- you want a GUI-only verification flow instead of a CLI
- your project does not use Starknet/Cairo at all
