Deserialize proof_a

[ppoliani]

I can see the tests here do some pre-processing on proof_a. I'm trying to do the same using JavaScript so i can then pass the value into a Solana Program. Could you share an example of how we can achieve the same thing in JS?

The code starting from this line https://github.com/Lightprotocol/groth16-solana/blob/master/src/groth16.rs#L316 does some transformation on proof_a which I can't find a way to accomplish in JS.

See this js code does the transformation, https://github.com/Lightprotocol/light-protocol/blob/deb9d9e0b90295c362beaf9f955fbb561ecba576/prover.js/src/prover.ts#L166-L293.
We will do a new prover.js release in a couple weeks which will include this functionality.

@ananas-block any updates on this sir? I need a prover can transformation the output to the right format for verify on-chain via Typescript too

This seem to work only for the Poseidon hash in the text, I tried it for other circuits and I’m always getting proof verification failed.
