TS SDK Move Types

When developing on Aptos, and specifically working with the SDK, developers often need to handle Move types serialization and deserialization. Whether is to construct a transaction payload, build a raw transaction or read BCS data.

The SDK provides a convenient Move subclasses to easily interact with move types to perform serialization or deserialization operations. Each class has a serialize, serializeForEntryFunction and serializeForScriptFunction methods and a deserialize static class.

In addition, for complex types like Vector the SDK supports nested serialization and deserialization.

Move primitive types​

Classes to handle Move primitive types:

  • U8
  • U16
  • U32
  • U64
  • U128
  • U256
  • Bool
  • AccountAddress
const serializer = new Serializer();

const u8 = new U8(1);
u8.serialize(serializer);
u8.serializeForEntryFunction(serializer);
u8.serializeForScriptFunction(serializer);

const deserializer = new Deserializer();
U8.deserialize(deserializer);

Move struct types​

  • MoveVector
  • MoveString
  • MoveOption
const serializer = new Serializer();

const moveString = new MoveString("hello world");
moveString.serialize(serializer);
moveString.serializeForEntryFunction(serializer);
moveString.serializeForScriptFunction(serializer);

const deserializer = new Deserializer();
MoveString.deserialize(deserializer);
