 We're building a zero-knowledge policy layer that lets institutions execute USDC settlements with cryptographic guarantees—no blind trust, no exposed policy details, just pure verifiable compliance.

Arc is incredible for USDC settlement. Fast. Cheap. Native.

institutions can't use it for treasury operations.

Because treasury policies are complex beasts:

Require 2-of-3 approvals for transfers >$100K

All payments must reference approved invoices

Today, enforcing these on-chain means either:

 (policy details, approvers, thresholds—all public)

 (trust a third party to say "yeah this is fine")

 (humans checking spreadsheets before signing)

None of these work for serious treasury operations.

Enter QVT (Quantum-Safe Verifiable Treasury)

We're building the infrastructure that bridges this gap.

Prove a transfer complies with policy WITHOUT revealing the policy

Vendor lists stay private. Approval thresholds stay private. Invoice details stay private.

But the proof is publicly verifiable on-chain

Trusted setup ceremony completed (proving key: 1MB, verification key: exported)

Solidity verifier auto-generated from snarkjs

Hybrid classical/PQ signatures for long-term receipts

Because treasury receipts need to last decades, not months

Smart contracts with real Groth16 verification

Trusted setup ceremony (simplified, but functional)

Full circuit with all predicates (EdDSA, Merkle proofs, threshold signatures)

Production MPC ceremony with multiple participants

function transfer(address to, uint256 amount) {

    require(msg.sender == treasuryMultisig); // Who decides if policy is met?

function executeProtectedTransfer(Intent memory intent, Proof memory proof) {

    require(verifyProof(proof.a, proof.b, proof.c, proof.publicInputs));

    // Proof shows: amount in bounds ✓ vendor whitelisted ✓ threshold met ✓

    // But reveals: nothing about actual policy

Policy commitment (hash of policy + salt + epoch)

Policy details, amounts, deadlines, vendor proofs, approvals

Arc's USDC-native settlement is perfect for this.

 Settlement finality matches proof verification time

 Groth16 verification is ~200k gas (cheap on Arc)

 No bridging risks for treasury operations

We're not building a generic zk-tool. We're building 

treasury infrastructure specifically designed for Arc's settlement layer.
