 | `INDEXER_TX_ACTIONS_REINDEX_PROTOCOLS`                        | Comma-separated names of protocols which should be indexed or reindexed on historical blocks defined by the range. Example: `uniswap_v3,zkbob` - only these protocols will be indexed or reindexed for the defined block range. If the value is an empty string (or not defined), all supported protocols will be indexed/reindexed. This option is not applicable to `realtime` and `catchup` fetchers (it always indexes all supported protocols).
