### Optimism Tables

Our Optimism data includes the following schemas and tables:

<table><thead><tr><th width="140.00000000000003">Schema</th><th width="340">Description</th><th>Tables</th></tr></thead><tbody><tr><td>Raw</td><td>Raw blockchain data.</td><td>blocks, transactions, logs, traces</td></tr><tr><td>Raw+</td><td>Deployed contracts with bytecode and ERC token data.</td><td>contracts, erc20\_tokens, erc721\_tokens, erc\_1155\_tokens </td></tr><tr><td>Assets</td><td>Token transfers for native ETH and ERC tokens. </td><td><p>fungible\_token\_transfers,</p><p>native\_token\_transfers,</p><p>erc20\_token\_transfers, <br />erc721\_token\_transfers, erc1155\_token\_transfers</p></td></tr></tbody></table>

*Our Optimism data tables are structurally similar to Ethereum across all schemas.*
