License the C100 index
The C100 family tracks the crypto market the way the Nasdaq-100 tracks large-cap equities: the largest eligible assets, capped so no single asset dominates, with published rules and history since 2020. It is available as a benchmark for financial products, as a data feed, and as the base for custom indexes.
What we offer
Benchmark license
Use C100, C25, C100-EW or C100-exBTC as the underlying or benchmark of a fund, ETP, structured note, tokenized product or index-linked contract. Includes official daily closes, rebalance files ahead of each review and index event notices.
Data license
Display or redistribute index levels, constituents and weights on an exchange, broker, wallet, terminal or data platform, with higher API limits and an agreed service level.
Custom indexes
A rules-based index built on the same engine: a different universe, size, sector focus, cap structure or rebalancing schedule, with its own point-in-time backtest and verifiable daily data.
Why C100
- Rules, not opinions
- Every selection, weight and rebalance follows the published methodology. Judgement is limited to emergencies and corporate actions, and every such decision is logged publicly.
- Verifiable to the last digit
- The units, divisor and prices behind every daily close are public, so anyone can recompute the index.
- Survivorship-free history
- The backtest uses each day's market ranking as it was, including assets that later collapsed or were delisted, and the same engine that runs the live index.
- Investable-minded screens
- Stablecoins, wrapped tokens, staking receipts and tokenized assets are excluded; liquidity, history and market-pair screens and buffer rules keep turnover in check.
