sequenceNumber

@SerialName(value = "sequence_number")

@Serializable(with = AptosDecimalStringULongSerializer::class)

Sequence number for the account, represented as a string-encoded 64-bit unsigned integer (u64).

The sequence number increases with each transaction submitted from this account. Returned as a string to avoid precision loss in languages like JavaScript, which do not natively support 64-bit integers in JSON.
