1async ({ request, data, label, addWallet }) => {
2    if (label === 'TRANSACTIONS' && data) {
3        for (const transaction of data) {
4            for (const toAddress of transation.to) {
5                const address = toAddress.address || toAddress;
6                if (address !== data.address) {
7                    await addWallet(address);
8                }
9            }
