Polygon runs on the Bor client, which does not implement the Erigon-only Parity `trace_*` or `erigon_*` namespaces. Migrate the `trace_*` methods to their `debug_*` equivalents:

| Parity `trace_*` method | Replacement on Bor |
| --- | --- |
| `trace_transaction` | [`debug_traceTransaction`](/reference/polygon-tracetransaction) with `callTracer` |
| `trace_block` | [`debug_traceBlockByNumber`](/reference/polygon-traceblockbynumber) with `callTracer` |
| `trace_call` | [`debug_traceCall`](/reference/polygon-tracecall) with `callTracer` |
| `trace_filter`, `trace_replayBlockTransactions`, `trace_replayTransaction` | [`debug_traceBlockByNumber`](/reference/polygon-traceblockbynumber) per block, or [`eth_getLogs`](/docs/understanding-eth-getlogs-limitations) for event ranges |

The `debug_trace*` methods return equivalent execution traces on Bor. The `erigon_*` convenience methods have no Bor equivalent — use the standard `eth_*` methods instead.

Polygon API method that returns traces for all the transactions within a specific block. Developers can use the `trace_block` method to gain insight into the behavior of smart contracts within a block, analyze gas usage and optimize their contracts accordingly. This method is only available on an Erigon instance.

<Warning>
**Not available on Polygon.** Chainstack serves Polygon on the Bor client (archive uses Bor with PBSS), which does not implement the Erigon-only `trace_*` namespace. Use [`debug_traceBlockByNumber`](/reference/polygon-traceblockbynumber) with the `callTracer`, which returns equivalent per-transaction call traces for a block on Bor.
