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 command-line tool, with the following usage:
python -m ai_dev_tool_base_mainnet_usdc --help
The configuration is defined using dataclasses, with strict validation to ensure correctness.
Exponential backoff with jitter is used to handle transient failures, and structured JSON logging is used for monitoring and debugging.
Deterministic error handling is implemented to ensure predictable behavior in case of errors.
Architecture:
- The module uses a separate thread for event indexing and receipt verification.
- The event indexer fetches events from the blockchain and stores them in a database.
- The receipt verifier fetches receipts from the blockchain and verifies their correctness.
- The module uses a bounded concurrency approach to ensure efficient and reliable event processing.
Bounded Concurrency:
- The module uses a semaphore to limit the number of concurrent event indexing and receipt verification tasks.
- The semaphore is initialized with a configurable number of slots, which determines the maximum number of⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License
