# Using Custom Contracts

> Using Custom SKALE IMA Contracts

## Recap

1. We have created a [custom contract](/developers/skale-bridge/messaging-layer/create-custom-contracts)
2. We have [connected](/developers/skale-bridge/messaging-layer/connect-custom-contracts) the custom Contracts
3. Now we are ready to test them! Follow the steps below.

    // The following can be replaced with "listening for an event", however,
    // a while loop is more intuitive for a new developer
    while (true) {
    	const lastNumber = await contractB.lastNumber();
    	if (lastNumber === BigInt(5)) {
    		console.log("Posted!");
    		break;
    	}
    	await new Promise(res => setTimeout(res, 2000)); // Sleep 2 seconds
    }
