Development Update — 2026-09-06

Overview: Where Development Is Heading

The backend is focused on hardening and scaling its multi-chain blockchain data ingestion and querying capabilities, with recent work centering on the chainWatch backfill pipeline. Recent improvements add configurable backfill modes with inline asset rewriting to CDN, granular per-chain and IPFS.io rate limiting with duplicate CID fetch caching, and persistent storage for learned contract signatures to cut down on redundant metadata lookups. Parallel efforts are refining NFT and collection query endpoints to support canonical name and chain slug inputs, fixing resolution edge cases, and cleaning up unused server routes alongside database schema tweaks to support larger supply values and non-fatal ingest writes.

Overview: Where Development Is Heading

Recent frontend development is centered on improving collection page performance, reliability, and SEO, with optimizations like parallelized loader fetches, corrected chain-aware slug and ID handling to cut redundant data refetches, and fixed SSR hydration to avoid unnecessary redirect-triggered revalidation. The team is also prioritizing discoverability and metadata accuracy, with updates to collection page JSON-LD breadcrumb data, restructuring of sitemaps to retain locale variants and split per blockchain chain, and alignment of collection info APIs with backend contracts.

Project Direction — Both repos are converging on a stable, production-ready NFT marketplace. The backend is hardening core systems while the frontend improves architecture and user experience.
