# USDai supply across chains

> USDai on every chain Voltfin covers, read from each contract's totalSupply() at the last block of every UTC day, in USD-pegged token units. The total counts native contracts only; bridged copies are listed separately and never added in. Monad and other chains will join once archive history is available.
