A chain is a blockchain: the network that transactions run on. Chains sit alongside projects and apps rather than inside them, and dimensions.chains names the project behind every chain.

Pages

Registry

Chain names, and the project that runs each one.

Transactions

Individual transactions with the fee each one paid. In progress.

Metrics

Daily chain fees, revenue, and the fees passed on.

Chains and projects

Where a project runs a blockchain, the two match one to one: gas paid on HyperEVM shows up in the daily chain table under chain_id = 'hyperevm' and rolls into Hyperliquid’s project fees. A chain’s project defaults to the chain’s own, and is overridden where another project’s app runs it: unichain resolves to uniswap. The daily chain table carries no project column; join chains.project_id to attribute a chain, and the transaction records already carry that column on every row.
