        });

        expect(events.map((x) => x.decodedData)).toEqual([
            [
                [
                    '0xF02f557c753edf5fcdCbfE4c1c3a448B3cC84D54',
                    '0x9E7911de289c3c856ce7f421034F66b6Cde49C39',
                    5000n
                ],
                ['0xF02f557c753edf5fcdCbfE4c1c3a448B3cC84D54', 3000n]
