Hi Alex, `@daml/ledger` is really intended to be used in combination with the JavaScript codegen which will generate the template for you. I recommend the related post at [Attempting to create a contract is sending the wrong templateId](https://discuss.daml.com/t/attempting-to-create-a-contract-is-sending-the-wrong-templateid/1910) for some more details on that.
