# Supply Change

> Mint and burn events that change a stablecoin's on-chain total supply.

The Stablecoins Supply Change table records every event that increases (mint) or decreases (burn) the on-chain total supply of a tracked stablecoin. Use it to track issuance and redemption flows, measure net supply expansion or contraction, and observe issuer behavior at the event level.
