We engineered this zero-bloat Cloudflare Workers / TypeScript blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

"""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 bounded concurrency to ensure efficient and reliable event processing.
The module is designed to be used as a command-line tool, with options for configuring the indexing and verification processes.
Usage:
python -m ai_dev_tool --config-path=/path/to/config.json --log-level=INFO
The configuration file should contain the following settings:
- chain_id: The ID of the Base Mainnet chain
- usdc_contract_address: The address of the USDC contract
- start_block: The starting block number for indexing
- end_block: The ending block number for indexing
- concurrency: The maximum number of concurrent indexing tasks
- log_level: The logging level (DEBUG, INFO, WARNING, ERROR, CRITICAL)
Architecture:
- The module uses a bounded concurrency approach to index on-chain events, with a maximum of 'concurrency' tasks running concurrently.
- Each indexing task retrieves a batch of events from the chain, processes them, and then verifies the corresponding receipts.
- The module uses exponential⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License
