Improvements & critical bugfix for Insight's NFT Metadata APIs

We’ve rolled out a series of performance upgrades across the board to make NFT metadata queries faster, smarter, and more reliable than ever.

What Changed?

⚡ Unified Fetching for NFT Data

• NFT metadata, ownership info, and token data are now pulled in a single optimised query internally, reducing the number of round trips and improving latency consistency.
• This makes NFT-related endpoints much more consistent at scale.

🧠 Smarter Metadata Handling

• Metadata is now fetched on-demand only when needed, skipping unnecessary lookups for already known or irrelevant data.
• We've introduced a system to automatically skip refetching metadata that’s deemed not worth roundtrips — improving efficiency without losing accuracy.

🪄 Parallel Processing & Query Optimizsation

• Queries for metadata are now parallelised, making better use of compute resources.
• Owner and balance aggregations are now handled more effectively, ensuring both speed and correctness in multi-owner or high-traffic collections.

🛠️ Critical Bugfix for NFT Transfers

• Fixed a major issue where NFT transfers were duplicated across chains. Transfer data is now properly filtered per chain, ensuring clean and accurate results.
• Transfer endpoints now properly correlated to chain identification to avoid any confusion in multichain contexts.

🔁 Same Gains for Fungible Tokens (ERC20)

All of these improvements won’t just apply to NFTs — we’re extending the same performance, consistency, and metadata logic enhancements to ERC20 tokens as well.

🔁 What's next? All of these improvements won’t just apply to NFTs — we’re extending the same performance, consistency, and metadata logic enhancements to ERC20 tokens as well.

💡 Result? lower and more predictable response times, better metadata hygiene, and fewer redundant operations — even across large multichain datasets.
