Current package status

Real provider snapshot · 2026-09-04Values were transcribed from CoinGecko’s Solana, Ethereum and Robinhood chain tables. Rankings follow CoinGecko’s estimated NFT market-cap order and are a static observation, not a streaming price feed.Open CoinGecko sourceRead methodology

The static package contains a normalized real-data file at /assets/data/collections-live.json. It includes 30 records: the first ten entries in each requested CoinGecko chain table as captured on 2026-09-04. It does not claim streaming updates and does not expose private API keys.

Ranking source

CoinGecko’s Solana, Ethereum and Robinhood NFT chain pages are the ranking sources. Their table order is based on estimated NFT market capitalization. NFTLeaderboard.com preserves both the chain rank and the CoinGecko global rank shown in the record.

CoinMarketCap and CryptoSlam were reviewed during research, but their public HTML did not expose a complete, directly usable three-chain top-ten table with the same fields in this environment. They were not merged merely to fill gaps.

Transcribed market fields

The normalized record contains native and USD floor, 24-hour, seven-day and 30-day floor change, native and USD estimated market cap, native and USD 24-hour volume, sales when published, chain rank and global rank.

The values are source-dated and can become stale. The current source link is shown in every row and profile.

Unavailable data

Owners, unique buyers, sellers, listings, listed percentage, supply, holder concentration, seven-day volume, 30-day volume and historical daily series are null because they were not published in the displayed chain table. The site does not calculate or copy them from an unrelated source.

Completeness is scoped to the eleven fields expected in this snapshot table, not to all possible collection analytics.

Collection images

Collection cards request the CoinGecko source thumbnail through an HTTPS image service with JPEG output and fixed dimensions. The original asset URL remains in the JSON and HTML for provenance. NFTLeaderboard.com does not watermark, modify or claim ownership of the third-party collection thumbnail.

A locally generated branded JPEG is an offline/error fallback only. Its metadata and caption state that it is not official collection artwork.

Robinhood distinction

CoinGecko’s Robinhood NFT chain table is the market-data source for the requested top ten Robinhood projects. Robinhood’s official help center is the separate source for wallet receipt, storage, sending and network support. One source does not validate claims from the other.

The site does not claim that Robinhood endorses the ranked collections or runs an NFT marketplace.

Refresh and corrections

To refresh the site, update real_nft_data.py from the current source tables, change the snapshot timestamp, regenerate the site and run quality_check.py. A correction email should identify the chain, collection, field, source URL and observation time.

Private credentials belong in server-side environment variables if a licensed API is added later.

The example below is included in /assets/data/collections-live.json. Null means unavailable from the selected snapshot source.
