Liteserver call over ADNL: liteServer.getAllShardsInfo. See lite_api.tl (checked 2026-10-25).

getShards returns the active shardchain block IDs at a masterchain sequence number. Each item is a complete block ID with workchain, shard, sequence, root hash, and file hash.

Use it to discover which shardchain blocks correspond to a masterchain block before fetching their headers or bodies. It differs from getMasterchainInfo, which returns only the current masterchain reference, and from lookupBlock, which resolves one block in a specified workchain and shard.

The masterchain seqno is a JSON number. Every returned shard identifier is rendered as signed decimal text so its 64-bit value remains exact.

Parameters

JSON-RPC params is a by-name object.

Params: object (by-name).

seqnointegerrequired

Non-negative masterchain block sequence number.

Response

Response fields

Field	Type	Description
`jsonrpc`	string	JSON-RPC protocol version.
`id`	number or string	Correlates the response with the request.
`result`	array	Active shardchain block IDs.
`result[].workchain`	integer	Workchain ID.
`result[].shard`	string	Signed 64-bit shard ID as decimal text.
`result[].seqno`	integer	Shardchain block sequence number.
`result[].root_hash`	string	Shardchain block root hash.
`result[].file_hash`	string	Shardchain block file hash.

The response is copied from the accepted live fixture.

Errors

See TON errors for the shared envelope and retention handling.

Code	Meaning	When it happens
`-32602`	Invalid params	`seqno` is missing, negative, malformed, or passed positionally.
`beyond_retention`	Shard state unavailable	The selected liteserver does not retain state at the requested masterchain block.
`-32601`	Method not found	The method is outside the published read-only catalog.
`401`	Unauthorized	The API key is missing or invalid.
`429`	Rate limited	The `ton_read_rpc_heavy` budget is exceeded.

Examples

JavaScript

const response = await fetch("https://triport.io/rpc/ton", {
  method: "POST",
  headers: { "x-token": process.env.TRIPORT_API_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({ jsonrpc: "2.0", id: "shards", method: "getShards", params: { seqno: 90110366 } }),
});
const { result: shards } = await response.json();

Notes

The input seqno identifies a masterchain block; item seqno values identify shardchain blocks and therefore need not equal it.
Pruned liteservers had a measured floor of 86 860 000. Genesis availability was observed on two nodes, but one measured server had a measured gap.
Requests use named params and batch results are matched by id.
No REST gateway or WebSocket shard subscription is published for TON.
