Integrating Snarkify SDK


The Snarkify SDK, a Rust-based library, offers a comprehensive interface for engaging with Snarkify Cloud. It allows for the swift conversion of your existing circuit code into a deployable prover. With Snarkify SDK's streamlined process, you can easily tap into the capabilities of Snarkify Cloud using just a handful of straightforward steps.


cargo add snarkify-sdk

Implement your prover

  1. Create a new file in your src/bin directory

  2. Implement the ProofHandler trait and prove method for proof creation

  3. Invoke snarkify_sdk::run::<{YourProofHandler}>() in the main function

Here's a snippet of code illustrating how to use the SDK:

use std::io;

use serde::{Deserialize, Serialize};
use snarkify_sdk::prover::ProofHandler;

struct MyProofHandler;

struct MyInput {
    public_input: String,

struct MyOutput {
    proof: String,

impl ProofHandler for MyProofHandler {
    type Input = MyInput;
    type Output = MyOutput;
    type Error = ();

    fn prove(data: Self::Input) -> Result<Self::Output, Self::Error> {
        Ok(MyOutput {
            proof: data.public_input.chars().rev().collect(),

fn main() -> Result<(), io::Error> {

Please also checkout this library for a ready-to-deploy example of Poseidon hash prover.

Testing locally

To run your prover locally, simply run,

cargo run --bin snarkify

and you can test the prover locally with a sample request like

curl --location --request POST 'http://localhost:8080' \
--header 'Content-Type: application/json' \
--header 'ce-specversion: 1.0' \
--header 'ce-id: abcdef123456' \
--header 'ce-source: test' \
--header 'ce-type: com.test.example' \
--data-raw '{
     "public_input": "aloha"
