Generate a balance proof

Prove you hold at least a threshold of SOL or an SPL token — without revealing the exact amount.

Inputs

Public: token, threshold
Private: balance (your actual holdings)

Generate

const proof = await zk.proveBalance({
  token: "SOL",
  min: 100,            // public threshold
  balance: 243.5,      // private — stays local
});

Submit and read back

const { signature, proofAccount } = await zk.submitProof(proof);

// later — anyone can verify
const onchain = await zk.getProof(proofAccount);
console.log(onchain.verified); // true

The verifier only sees the threshold and the validity of the proof — never your balance.
