[iansamz]

How does a one the latest round data similar to EVM chain get latest data
If non is available, show an example for how to get this from data.onRound listener

[archseer]

You could wrap the onRound listener into a promise, we do that in the tests:

chainlink-solana/ts/src/index.test.ts

Lines 94 to 101 in 805ddc7

	let resolve;
	let promise = new Promise<Round>((r) => (resolve = r));
	let num;
	num = cl.onRound(CHAINLINK_STORE_PROGRAM_ID, (round) => {
	resolve(round);
	cl.removeListener(num);
	});
	let got = await promise;
