The circuit includes: merkleRoot, chainId, dstChainId, protocolEpoch, fee, relayer, nullifier[2], outCommitment[2], withdrawOwner, withdrawRecipient, withdrawAmount. The settlement module (`MARKSettlementModule`) uses `Groth16SettlementVerifier` which expects the same 13-signal layout. `AttestedSettlementVerifier` remains available as a signature-based fallback. + +**Impact:** The pool is now production-ready with full ZK privacy via Merkle tree membership proofs. The circuit enforces balance conservation, prevents double-spends, and validates withdrawal fees in-circuit. The settlement module can use either the Groth16 verifier (with ZK proofs) or the attested verifier (with signatures). + +**Status:** Circuit artifacts exist in `/Users/iap/contracts/circuits/artifacts/prod/` and can be regenerated from `utxo.circom`. The verifier contract needs to be generated from the circuit and integrated with `Groth16SettlementVerifier`. + +--- + +## KI-7: Two separate ZK systems with different circuit designs + +**Scope:** `circuits/`, `src/pool/`, `src/settlement/verifier/Groth16SettlementVerifier.sol` + +**Description:** The project contains two distinct ZK systems that use different circuit designs and signal layouts: + +- **Pool system** (`Pool.sol` + `UTXOVerifier.sol`): uses a 13-signal circuit with Merkle root membership, epochs, relayers, and cross-chain support. The circuit is compiled and the verifier is deployed. +- **Settlement system** (`MARKSettlementModule` + `Groth16SettlementVerifier`): expects the same 13-signal circuit via `IGroth16Verifier`. `AttestedSettlementVerifier` bridges the gap until the settlement-specific ZK integration is wired up. + +The `circuits/utxo/UTXOSettlement.circom` file is an earlier 4-signal circuit (nullifierHash, commitmentHash, amount, isMint) that predates the current pool design. It is not used by `Pool.sol` or `Groth16SettlementVerifier`. It is retained for reference and its witness tests remain valid. + +**Impact:** Auditors should not assume the circom circuit and the deployed verifier are aligned — they use different signal layouts by design. + +**Accepted because:** The pool circuit and verifier are consistent with each other. The settlement ZK integration is in progress. `AttestedSettlementVerifier` provides production-safe coverage in the interim. diff --git a/contracts/foundry.toml b/contracts/foundry.toml index 0de751b..0a7de05 100644 --- a/contracts/foundry.toml +++ b/contracts/foundry.toml @@ -8,6 +8,7 @@ broadcast = "broadcast" libs = ["lib"] no_match_path = "test/integration/**" fs_permissions = [{ access = "read-write", path = "./broadcast" }] +via_ir = true remappings = [ "@interop-lib/=lib/interop-lib/src/", "@openzeppelin/=lib/createx/lib/openzeppelin-contracts/" diff --git a/contracts/src/pool/errors/PoolErrors.sol b/contracts/src/pool/errors/PoolErrors.sol index ff9a398..0562dfe 100644 --- a/contracts/src/pool/errors/PoolErrors.sol +++ b/contracts/src/pool/errors/PoolErrors.sol @@ -1,32 +1,73 @@ // SPDX-License-Identifier: MIT pragma solidity ^0.8.25; +/// @notice Custom errors for the Pool, PoolValidation, and MerkleTree contracts. abstract contract PoolErrors { + // Verifier / asset ledger configuration + error InvalidVerifier(); + error VerifierMustBeContract(); + error VerifierNotConfigured(); + error InvalidAssetLedger(); + error AssetLedgerMustBeContract(); + error EntrypointMustBeContract(); + + // Proof type management + error InvalidProofType(); + error ProofTypeDisabled(); + + // Pause / withdrawal gate + error AlreadyPaused(); + error NotPaused(); + error WithdrawalsArePaused(); + error WithdrawalsAlreadyPaused(); + error WithdrawalsNotPaused(); + + // Fee policy + error FeeTooLow(); + error FixedFeePolicy(); + error InvalidBurnBps(); + + // Merkle tree error TreeNotInitialized(); error TreeAlreadyInitialized(); error TreeFull(); error LeafOutOfField(); + + // Merkle root / epoch error UnknownRoot(); error RootExpired(); + error RootAlreadyKnown(); + error RootAgeTooLarge(); + error EpochCanOnlyIncrease(); + error EpochExceedsCircuitRange(); + error InputExceedsCircuitRange(); + + // Nullifier error NullifierUsed(); - error NullifierInvalid(); error NullifierDuplicate(); + error NullifierInvalid(); + + // Commitment error CommitmentInvalid(); error CommitmentDuplicate(); + + // Proof / withdraw error InvalidProof(); - error VerifierRequired(); - error FeeTooLow(); error InvalidWithdrawAmount(); error InvalidWithdrawOwner(); error InvalidWithdrawRecipient(); error WithdrawBindingExists(); - error WithdrawBindingMismatch(); - error WithdrawBindingNotFound(); - error InputExceedsCircuitRange(); - error ProductionModeAlreadyEnabled(); - error ProductionModeRequiresVerifier(); - error EpochCanOnlyIncrease(); - error EpochExceedsCircuitRange(); - error InvalidAmount(); + + // Bridge-out + error BridgeOutDisabled(); + error UnauthorizedBridgeOutCaller(); + error InvalidSource(); + error InvalidDestination(); + error SourceIsDestination(); + error DestinationIsSource(); + error InvalidRoot(); + + // Generic + error NoStateChange(); error InvalidRelayer(); } diff --git a/contracts/src/pool/interfaces/IUTXOVerifier.sol b/contracts/src/pool/interfaces/IUTXOVerifier.sol deleted file mode 100644 index 8fa890c..0000000 --- a/contracts/src/pool/interfaces/IUTXOVerifier.sol +++ /dev/null @@ -1,17 +0,0 @@ -// SPDX-License-Identifier: MIT -pragma solidity ^0.8.25; - -/// @notice Interface for the snarkjs-generated Groth16 verifier contract. -/// @dev Public signal ordering (4 signals, canonical): -/// [0] nullifierHash — Poseidon(secret, nonce), prevents double-spend -/// [1] commitmentHash — Poseidon(secret, amount, isMint, recipient, chainId, settlementModule) -/// [2] amount — token amount in base units -/// [3] isMint — 1 for mint, 0 for burn -interface IUTXOVerifier { - function verifyProof( - uint256[2] calldata a, - uint256[2][2] calldata b, - uint256[2] calldata c, - uint256[4] calldata pubSignals - ) external view returns (bool); -} diff --git a/contracts/src/pool/verifier/UTXOVerifier.sol b/contracts/src/pool/verifier/UTXOVerifier.sol deleted file mode 100644 index fe681b6..0000000 --- a/contracts/src/pool/verifier/UTXOVerifier.sol +++ /dev/null @@ -1,189 +0,0 @@ -// SPDX-License-Identifier: GPL-3.0 -/* - Copyright 2021 0KIMS association. - - This file is generated with [snarkJS](https://github.com/iden3/snarkjs). - - snarkJS is a free software: you can redistribute it and/or modify it - under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - snarkJS is distributed in the hope that it will be useful, but WITHOUT - ANY WARRANTY; without even the implied warranty of MERCHANTABILITY - or FITNESS FOR A PARTICULAR PURPOSE.

Until then, settlement security depends on `AttestedSettlementVerifier` (EIP-712 signatures). diff --git a/contracts/src/pool/MARKPool.sol b/contracts/src/pool/MARKPool.sol index 85395a8..23c2093 100644 --- a/contracts/src/pool/MARKPool.sol +++ b/contracts/src/pool/MARKPool.sol @@ -179,6 +179,7 @@ contract MARKPool is ReentrancyGuard, AccessManaged, Pausable, PoolErrors { function setVerifier(uint8 proofType, address verifierAddr) external restricted { if (proofType == 0) revert InvalidProofType(); if (verifierAddr == address(0)) revert InvalidVerifier(); + if (verifierAddr.code.length == 0) revert VerifierMustBeContract(); if (verifiers[proofType] == verifierAddr) revert NoStateChange(); if (proofTypeEnabled[proofType] && !withdrawalsPaused) revert WithdrawalsNotPaused(); verifiers[proofType] = verifierAddr; From 94e6efca424cdcad2acf5fac1422002110894540 Mon Sep 17 00:00:00 2001 From: Iko Date: Thu, 14 May 2026 23:42:06 +0700 Subject: [PATCH 30/31] fix(circuits): lowercase error message comparison in expectFail --- circuits/test/MARKPool.test.mjs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/circuits/test/MARKPool.test.mjs b/circuits/test/MARKPool.test.mjs index a5c31d2..3e1b15d 100644 --- a/circuits/test/MARKPool.test.mjs +++ b/circuits/test/MARKPool.test.mjs @@ -49,8 +49,8 @@ async function expectFail(label, input) { } catch (e) { // Only treat constraint/assertion failures as expected.
