[Solved] 转账交易广播后 InsufficientCellCapacity

用 Ruby SDK 构建了一个交易,input 有 81 个 CKB,outputs 加起来一共 80.996 CKB,为什么广播后会报错:jsonrpc error: {:code=>-3, :message=>"Transaction(InsufficientCellCapacity)"}

是因为找零 Cell 的 capacity 太小,不足以覆盖 Cell 本身的大小?我把找零改成 10.999 CKB 发现还是一样报错,那么一个 Cell 最小的 capacity 是多少呢?53 CKB 吗?

61 CKB

目前(用默认的 lock), 一个 Cell 最小的 Capacity 要求为 61CKB
