- description
- Interact with Erc20 smart contract via read/write functions
Workflow
- Setup: Configure environment variables
RPC_URL,PRIVATE_KEY,CONTRACT_ADDRESS - Read: Use read functions (view/pure) to query contract state
- Write: Use write functions to modify contract state (requires gas)
Constraints
| Constraint | Requirement |
|---|---|
| RPC Provider | Any Ethereum JSON-RPC endpoint |
| Private Key | Must have contract permissions |
| Gas Limit | Adjust based on function complexity |
| Network | Must match contract deployment |
