Architect JWT capability payload parsing for high-throughput indexer API

[Damola-Sodiq]

Description

Develop a backend mechanism utilizing JWT capability payload parsing to resolve performance bottlenecks during heavy Web3 webhook ingestion.

Architecture & Context

The Fastify and Prisma backend in tokenized-fractional faces extreme concurrency when blocks finalize. Utilizing JWT capability payload parsing ensures state consistency and unblocks the Node.js event loop.

Technical Requirements

• Implement non-blocking asynchronous architectures.
• Maintain absolute type safety across the tRPC boundary.
• Ensure backward compatibility with existing Prisma schemas.

Acceptance Criteria

• Execution completes without blocking parallel operations.
• Edge cases and malformed inputs are gracefully rejected.
• The implementation performs optimally under heavy simulated load.
