Returns the summary range (and ethereum transaction hash if the summary is published) which includes the passed block number.

await api.query.getSummaryData(blockNumber);

important

You can get the AVN_GATEWAY_URL here.

REQUEST PARAMS

• blockNumber [optional] - a string representing the block number to check (if none is passed the current finalized block is used).

RESULT FIELDS

• blockNumber - the passed or current finalized block number range - 2 element array with start and end block numbers of the summary (if the block falls within a summary range).
• ethTxHash - Ethereum transaction hash of the published summary (if the summary root has been checked in by that point).

Example

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const AVN_GATEWAY_URL = "gateway url of your chosen network";
const options = {
    suri: "suri of your account",
    setupMode: SetupMode.SingleUser,
    signingMode: SigningMode.SuriBased,
};

const blockNumber = "1234";

async function main() {
    await avnSdk.init();
    const api = await avnSdk.apis();

    let result = await api.query.getSummaryData(blockNumber);
    console.log(result);
}

(async () => {
    await main();
})();

Example Result

{
    "blockNumber": "1234",
    "summaryRange": ["0", "28800"],
    "ethTxHash": "0x32c40ef26710a2ed40d2b14ef9a92aab859cb35a92a279d6bc3fbb6fea84089f"
