Open data

The Exit-Friction dataset

What selling a crypto position actually returns, measured every day and published as data. Free for any use, including commercial — credit Cryptominium and link the source.

Each day we ask live DEX routing for a $100,000 sell of every token we track, on each chain we read, and record how much of the quoted value is lost to price impact. The monthly Exit-Friction Index is the median of each token’s own median. This dataset is that index and the per-token figures it is computed from, so anyone can check it.

Download

• exit_index.csv — one row per month (2 so far), the open month marked provisional.
• exit_tokens.csv — one row per token, chain and month (141 rows): the figures each month’s median is taken over.
• README.md (every column explained), datapackage.json, CITATION.cff, LICENSE.txt

Monthly releases

Each closed month is frozen as a release that never changes, so a paper can cite exactly what it used.

• August 2026 · 78 tokens, median 14.99% · per-token file reconstructed, incomplete

What is not in it

No personal data of any kind: nothing anybody searched for, no wallets or addresses people looked up, no visitor data. And not the upstream market data our measurements are computed against — prices and pool liquidity belong to their providers. Every number here is one we measured.

Limits

• One sell size, $100,000. Friction at $1,000 or $10 million is a different number.
• On-chain only. Tokens that trade mostly on centralised exchanges are deliberately not measured.
• Aggregator quotes, not executed trades.
• August 2026 closed before per-token figures were frozen: the index was published over 78 tokens, and 54 tokens’ readings survived to be exported. Those rows are marked reconstructed.
