Parameters

  • seqno (integer, required) — The sequence number of the masterchain block. Example: 40467413.

​
Response

  • shards (array) — An array of shard objects, each containing:
    • workchain (integer) — The workchain ID.
    • shard (string) — The shard identifier.
    • seqno (integer) — The sequence number of the shard block.
    • rootHash (string) — The root hash of the shard block.
    • fileHash (string) — The file hash of the shard block.

​
Use case

The masterchainBlockShards endpoint is useful for applications that need to analyze or track the state of shards within a specific masterchain block. This information can be valuable for:
  1. Blockchain explorers that want to display detailed information about the structure of the TON blockchain at a specific point.
  2. Analytics tools that need to monitor the distribution and state of shards across workchains for a given masterchain block.
  3. Developers building applications that require knowledge of the shard structure for optimization or routing purposes.
