v1.0.0Interact with Erc20 smart contract via read/write functions
by 详细分析 ▾
运行时依赖
版本
Initial release of erc20-skill. - Enables interaction with ERC20 smart contracts for both read and write operations. - Supports essential read functions: name, symbol, decimals, totalSupply, balanceOf, allowance. - Implements core write functions: transfer, approve, transferFrom, mint, burn. - Provides workflow and environment setup instructions. - Lists key constraints for proper operation. - Includes event descriptions for Transfer and Approval.

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 |
