Actionable market data for digital assets

DASID is an open identifier standard for digital assets. One identifier structure maps every instrument, on every chain and at every venue, back to what it represents. The full specification is published at dasid.org.

DASID carries crosswalks to CUSIP, ISIN and FIGI, so onchain instruments resolve into the reference-data model you already run rather than sitting beside it.

Prices are blended across venues using a transparent, configurable methodology. Every blended price stores its methodology version, its principal market and every input, including the ones that were rejected and why. Methodology versions are dated and immutable, written against ASC 820 and IFRS 13, so a past valuation reproduces exactly for an audit, an examination or a client challenge.

Data ships in seven layers, and Identity is the one every other layer resolves inward to: what an asset is and where it trades. Tape is what traded and at what price. Book is the size behind that price. Execution is cost, venue quality, funding and order flow. Valuation is what it is worth, defensibly. Examination reconstructs and proves what happened. Convexity covers non-linear payoffs. Tape and Book each cover spot and derivatives from one set of endpoints.
