     - `TON_INDEXER_START_SEQNO` *(required)* — masterchain seqno to start with. The service starts indexing from this value in 2 directions: to the latest blocks and to the earliest blocks.
     - `TON_INDEXER_BOTTOM_SEQNO` *(required)* — the earliest masterchain seqno. The service will not index blocks earlier this value. Make sure that this seqno exists in lite server that you are using.
     - `TON_INDEXER_HTTP_PORT` *(default: 80)* — port for API webserver.
