nearprotocol - Can I query a Near contract for its method signatures?

Question

Is there a way to query what methods are offered by a given NEAR contract? (So that one could do autodiscovery of some standard interface, for instance.) Or do you have to just know the method signatures already before you can interact with a contract?

Answer 1

No not yet. Currently all contract methods have the same signature. () -> () No arguments and nothing is returned. Each method has a wrapper function that deserializes the input bytes from a host; calls the method; and serializes the return value and passes the bytes back to the host.

This is done with input and value_return. See input..

There are plans to include the actual signatures of the methods in the binary in a special section, which would solve this issue.
