Decoded trace calls on Base.

## Table Columns

<table><thead><tr><th width="216">Column Name</th><th>Example</th></tr></thead><tbody><tr><td>name</td><td>Decoded trace call name.</td></tr><tr><td>input\_params</td><td>Decoded input data in JSON format.</td></tr><tr><td>output\_params</td><td>Decoded output data in JSON format.</td></tr><tr><td>transaction\_hash</td><td>Unique identifier of the transaction that contains this trace.</td></tr><tr><td>transaction\_index</td><td>The position of this transaction in the block that it belongs to. The first transaction has index 0.</td></tr><tr><td>from\_address</td><td>The address of the sending party of this trace.</td></tr><tr><td>to\_address</td><td>The address of the receiving party of this trace (null for contract creation).</td></tr><tr><td>value</td><td>The amount of ether moved from the from\_address to to\_address.</td></tr><tr><td>input</td><td>The bytecode of the call that is made to another smart contract.</td></tr><tr><td>output</td><td>The bytecode answer the smart contract that was called gives back.</td></tr><tr><td>trace\_type</td><td>The value of the method such as call, create, create2, suicide.</td></tr><tr><td>call\_type</td><td>The type of method such as call, delegatecall, staticcall.

Possible values: block, uncle</td></tr><tr><td>gas</td><td>Gas provided with the trace call, in wei.</td></tr><tr><td>gas\_used</td><td>The amount of gas consumed, in wei.</td></tr><tr><td>subtraces</td><td>Number of children traces.</td></tr><tr><td>trace\_address</td><td>The address of the trace within the call graph. More detail to come soon.</td></tr><tr><td>error</td><td>Human readable developer error message. Examples: "Out of gas", "Reverted", "Bad instruction", "Bad jump destination".</td></tr><tr><td>status</td><td>Success status of the trace. Either 1 (success) or 0 (failure). Error messages take precedence over trace status. Note that debug\_trace methods may still return status = 1 for error traces.</td></tr><tr><td>block\_timestamp</td><td>The time when the block that contains this log was included on the blockchain.</td></tr><tr><td>block\_number</td><td>The length of the chain, in blocks.</td></tr><tr><td>block\_hash</td><td>Unique identifier of the block that includes this log.</td></tr><tr><td>trace\_id</td><td>Unique identifier for this trace. Generated by combining the trace\_type, transaction\_hash and trace\_address.</td></tr><tr><td>selector</td><td>Selector of the txn.</td></tr><tr><td>input\_params\_keys\_mapping</td><td>Input parameters mapping.</td></tr><tr><td>output\_params\_keys\_mapping</td><td>Output parameters mapping</td></tr><tr><td>interface\_id</td><td>Interface ID.</td></tr><tr><td>\_created\_at</td><td>Timestamp of the entry creation.</td></tr><tr><td>\_updated\_at</td><td>Timestamp of the entry update.</td></tr></tbody></table>
