Chain Signatures Don't Need A Special RPC

   do you need to talk to a different RPC or talk to a different relayer what's nice about this solution is that it's just a regular near transaction so you're just calling this method sign on the NPC contract and there are these nodes that are basically these are near validators but what they're doing is they're running a little what I what I sometimes refer to as like a side car piece of code they're just running like a little like a little sidecar on a motorcycle that basically allows them to

   to basically put in their portion of the signature that gets generated in the NPC contract so when you make a regular near transaction and you call sign the these nodes are going to spring into action because they're looking at the chain and they're they're they're checking out there's like oh somebody called sign so they spring into action and they start all kind of providing their portion of the threshold signature that you need in

   order to be be a valid signature and then once the threshold is reached you'll get a response in in just the same way that you would like send near or whether you would do like a near contract call you get a response and in that success value of your response like the you just parse out the signature and then you basically attach the signature to your transaction and that's the step

   three that I mentioned before you can you can broadcast that to the chain so as a developer you don't really need to understand and much Beyond regular near transactions there's no extra rpcs to configure this isn't a separate Network this is something that will exist on near as sort of a like a protocol layer on near as a service
