The complete coverage of RWA tokens is available in the `crosschain.rwa.tokens` table. ## Tables | Table Name | Description | | ------------------------------ | -------------------------------------------------------------------------- | | `crosschain.rwa.supply` | Daily supply snapshots of RWA tokens across different blockchains. | | `crosschain.rwa.supply_change` | Transfers that resulted in supply changes (mints and burns) of RWA tokens. | ## Table Columns Daily supply snapshots of RWA tokens. Unique key: `date`, `chain`, `token_address` | Column Name | Description | | ---------------- | ---------------------------------------------------------------------------------------------------------------------- | | `date` | The date of the supply snapshot | | `rwa_class` | **(Deprecated — removed March 15, 2026)** Classification of the RWA token.

This is a filtered view of the transfers table showing only mint and burn events. Unique key: `unique_id` | Column Name | Description | | ----------------------- | ---------------------------------------------------------------------------------------------------------------------- | | `rwa_class` | **(Deprecated — removed March 15, 2026)** Classification of the RWA token.
