# Supply

> Daily supply snapshots and supply change events (mints and burns) for RWA tokens.

## Overview

The supply tables track the circulating supply of RWA tokens over time, including daily snapshots and individual mint/burn events that change the supply.

The complete coverage of RWA tokens is available in the `rwa.registry.deployments` table.

## Tables

| Table Name | Description |
| - | - |
| `rwa.core.supply_daily` | Daily supply snapshots of RWA tokens across different blockchains. |
| `rwa.core.supply_latest` | Most recent (last 3 days) daily supply snapshot, deduplicated to one row per token. Same schema as `rwa.core.supply_daily`. |
| `rwa.core.supply_change` | Transfers that resulted in supply changes (mints and burns) of RWA tokens. |

<Accordion title="Legacy Schema">
  `crosschain.rwa.supply` is deprecated in favor of `rwa.core.supply_daily` above, and `crosschain.rwa.supply_change` is deprecated in favor of `rwa.core.supply_change` above. Both remain queryable, but new work should use the current schema. `rwa.core.supply_latest` is new — there is no legacy equivalent.
