Currency Cube

The Currency Cube provides a unified, chain-agnostic price for an asset in USD, such as Bitcoin by aggregating prices and volumes from all its representations (e.g., WBTC, cbBTC, and other bridged or wrapped forms) across all supported chains. This multi-chain cryptocurrency price data approach ensures consistent pricing across different blockchain implementations.

Use this for cross-chain assets, not for a single token

Currency prices aggregate across chains and token representations, so use this cube when you want one global number for an asset like BTC or ETH. For the price of a specific token on a specific market, use the Pairs cube with Ranking: { Position: { eq: 1 } }. Note that Ranking is not available on Currencies — it exists on Trades, Pairs, and Tokens only.

How OHLC is Calculated

The OHLC values (Open, High, Low, Close) describe a single computed cross-chain index series for the asset over the selected interval (e.g., 60 seconds). Within each interval the cube tracks the decay-weighted, volume-weighted blend of the asset's token representations — see Price Index Algorithm — and records that blend's open, high, low and close:

• Open: the index value at the start of the interval.
• High: the highest value the index reached during the interval.
• Low: the lowest value the index reached during the interval.
• Close: the index value at the end of the interval.

The index is not a min/max envelope across chains

High and Low are not the maximum and minimum of the per-chain prices. Because the index is a volume-weighted blend, an extreme print on a single chain — especially a thin one — is damped and may never reach the currency candle at all. A single representation can print far outside the currency's High/Low band without moving it.

Individual chain representations can therefore sit outside the currency's High/Low band. If you are monitoring a depeg or a single-venue dislocation, query the constituents through Tokens filtered on Currency.Id rather than relying on the currency candle to surface it.

Volume.Quote vs Volume.Usd: For USD-based pricing, Volume.Quote is the sum of quote token amounts (not USD). Use Volume.Usd for USD totals. See Price Index Algorithm for details.

Supply

• Supply: Currency-level supply and USD valuation metrics for the asset (aligned with the same Supply fields on Tokens and Pairs). See Supply fields reference for definitions of each subfield.
