AI Dev Tool: Base Mainnet USDC On-Chain Event Indexer & Receipt Verifier
This module provides a production-ready implementation of an on-chain event indexer and receipt verifier for the Base Mainnet USDC.
It utilizes a bounded concurrency approach to ensure efficient and reliable event processing.
The module can be used as a CLI tool, with the following usage:
python -m ai_dev_tool --rpc-url <RPC_URL> --contract-address <CONTRACT_ADDRESS> --start-block <START_BLOCK> --end-block <END_BLOCK>
The module consists of the following components:
- Dataclasses for configuration and event data
- Exponential backoff with jitter for handling RPC request failures
- Structured JSON logging for monitoring and debugging
- Deterministic error handling for ensuring data consistency and integrity
Configuration:
- rpc_url: The URL of the Ethereum RPC endpoint
- contract_address: The address of the USDC contract
- start_block: The starting block number for event indexing
- end_block: The ending block number for event indexing
- concurrency: The maximum number of concurrent RPC requests
Usage:
- python -m ai_dev_tool --rpc-url https://mainnet.infura.io/v3/<PROJECT_ID> --contract-address 0xA0b⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License
