PMKT/1 Protocol Alignment Validation

Overview

This document validates that the ConditionalMarketFactory (CMF) implementation with CTF1155 integration is aligned with the pmkt/1 protocol specification.

✅ Data Structure Alignment

Order Structure (pmkt/1 Spec)

struct Order {
    address maker;           // Order creator
    address makerAsset;      // Token maker is selling (CTF 1155 or ERC20)
    address takerAsset;      // Token maker wants to buy
    uint256 makerAmount;     // Amount maker is selling
    uint256 takerAmount;     // Amount maker wants to receive
    uint256 nonce;           // Unique nonce for cancellation
    uint256 expiration;      // Order expiration timestamp
    bytes32 salt;            // Random salt for uniqueness
    bool isMakerERC1155;     // True if maker asset is ERC1155
    bool isTakerERC1155;     // True if taker asset is ERC1155
    uint256 makerTokenId;    // Token ID if ERC1155 (0 for ERC20)
    uint256 takerTokenId;    // Token ID if ERC1155 (0 for ERC20)
}

PredictionMarketExchange Implementation

struct Order {
    address maker;           // ✅ ALIGNED
    address makerAsset;      // ✅ ALIGNED - CTF 1155 or ERC20
    address takerAsset;      // ✅ ALIGNED
    uint256 makerAmount;     // ✅ ALIGNED
    uint256 takerAmount;     // ✅ ALIGNED
    uint256 nonce;           // ✅ ALIGNED
    uint256 expiration;      // ✅ ALIGNED
    bytes32 salt;            // ✅ ALIGNED
    bool isMakerERC1155;     // ✅ ALIGNED
    bool isTakerERC1155;     // ✅ ALIGNED
    uint256 makerTokenId;    // ✅ ALIGNED - Position ID
    uint256 takerTokenId;    // ✅ ALIGNED - Position ID
}

Status: ✅ FULLY ALIGNED

✅ CTF1155 Integration (pmkt/1 Section 325-330)

pmkt/1 Requirements:

1. Market IDs correspond to CTF condition IDs
2. Position IDs are used as ERC1155 token IDs
3. Collateral token is specified in maker/taker assets

ConditionalMarketFactory Implementation:

1. Market ID → Condition ID Mapping

struct Market {
    // ...
    bytes32 conditionId;       // ✅ CTF condition ID stored
    bytes32 questionId;        // ✅ CTF question ID stored
    uint256 passPositionId;    // ✅ ERC1155 token ID for pass
    uint256 failPositionId;    // ✅ ERC1155 token ID for fail
    // ...
}

Implementation:

// Generate unique question ID
bytes32 questionId = keccak256(abi.encodePacked("market", marketId, proposalId, block.timestamp));

// Prepare condition with 2 outcomes (binary)
bytes32 conditionId = ctf1155.prepareCondition(address(this), questionId, 2);

Status: ✅ ALIGNED - Each market has a corresponding CTF condition ID

2. Position IDs as ERC1155 Token IDs

// Calculate position IDs for pass (index 1) and fail (index 2) outcomes
bytes32 passCollectionId = ctf1155.getCollectionId(bytes32(0), conditionId, 1);
bytes32 failCollectionId = ctf1155.getCollectionId(bytes32(0), conditionId, 2);

uint256 passPositionId = ctf1155.getPositionId(IERC20(collateralToken), passCollectionId);
uint256 failPositionId = ctf1155.getPositionId(IERC20(collateralToken), failCollectionId);

CTF1155 Position Calculation (Gnosis Standard):

function getCollectionId(
    bytes32 parentCollectionId,
    bytes32 conditionId,
    uint256 indexSet
) public pure returns (bytes32) {
    return keccak256(abi.encodePacked(parentCollectionId, conditionId, indexSet));
}

function getPositionId(IERC20 collateralToken, bytes32 collectionId) public pure returns (uint256) {
    return uint256(keccak256(abi.encodePacked(collateralToken, collectionId)));
}

Status: ✅ ALIGNED - Position IDs follow Gnosis CTF standard and are used as ERC1155 token IDs

3. Collateral Token Specification

struct Market {
    address collateralToken;   // ✅ Collateral token address stored
    // ...
}

// Market creation requires ERC20 collateral
require(collateralToken != address(0), "CTF requires ERC20 collateral");

Status: ✅ ALIGNED - Collateral token is specified and validated

✅ EIP-712 Signature Format Alignment

pmkt/1 Domain Separator (Section 184-191)

{
    name: "PredictionMarketExchange",
    version: "1",
    chainId: 61,  // ETC mainnet
    verifyingContract: <exchange_address>
}

PredictionMarketExchange Implementation

constructor(address _feeRecipient) 
    EIP712("PredictionMarketExchange", "1")  // ✅ ALIGNED
    Ownable(msg.sender) 
{
    require(_feeRecipient != address(0), "Invalid fee recipient");
    feeRecipient = _feeRecipient;
}

Status: ✅ ALIGNED - Uses exact name and version from spec

Order Type Hash (Section 196-210)

// pmkt/1 spec
struct Order {
    address maker;
    address makerAsset;
    address takerAsset;
    uint256 makerAmount;
    uint256 takerAmount;
    uint256 nonce;
    uint256 expiration;
    bytes32 salt;
    bool isMakerERC1155;
    bool isTakerERC1155;
    uint256 makerTokenId;
    uint256 takerTokenId;
}

// PredictionMarketExchange implementation
bytes32 public constant ORDER_TYPEHASH = keccak256(
    "Order(address maker,address makerAsset,address takerAsset,uint256 makerAmount,uint256 takerAmount,uint256 nonce,uint256 expiration,bytes32 salt,bool isMakerERC1155,bool isTakerERC1155,uint256 makerTokenId,uint256 takerTokenId)"
);

Status: ✅ ALIGNED - Order type hash matches pmkt/1 specification exactly

✅ Market Integration Points

Trading Flow Compatibility

1. Market Creation (ConditionalMarketFactory)

   // Creates CTF condition and position IDs
   bytes32 conditionId = ctf1155.prepareCondition(address(this), questionId, 2);
   uint256 passPositionId = ctf1155.getPositionId(collateralToken, passCollectionId);
   uint256 failPositionId = ctf1155.getPositionId(collateralToken, failCollectionId);
   

   Status: ✅ COMPATIBLE - Generates position IDs that can be used in pmkt/1 orders

2. Order Creation (Off-chain with pmkt/1)

   Order memory order = Order({
       maker: msg.sender,
       makerAsset: address(ctf1155),          // ✅ CTF1155 contract address
       takerAsset: collateralToken,           // ✅ Collateral token address
       makerAmount: amount,
       takerAmount: price,
       nonce: currentNonce,
       expiration: block.timestamp + 1 days,
       salt: randomSalt,
       isMakerERC1155: true,                  // ✅ CTF position is ERC1155
       isTakerERC1155: false,                 // Collateral is ERC20
       makerTokenId: passPositionId,          // ✅ Uses position ID from CMF
       takerTokenId: 0                        // ERC20 doesn't use token ID
   });
   

   Status: ✅ COMPATIBLE - Can create valid pmkt/1 orders using CMF-generated position IDs

3. Order Filling (PredictionMarketExchange)

   function fillOrder(
       Order calldata order,
       bytes calldata signature,
       uint256 takerAmount
   ) external nonReentrant returns (uint256, uint256) {
       // Verifies signature and executes transfer
       if (order.isMakerERC1155) {
           IERC1155(order.makerAsset).safeTransferFrom(
               order.maker,
               msg.sender,
               order.makerTokenId,  // ✅ Uses position ID from order
               makerFillAmount,
               ""
           );
       }
       // ...
   }
   

   Status: ✅ COMPATIBLE - Correctly handles CTF1155 position transfers

4. Market Resolution (ConditionalMarketFactory)

   function resolveMarket(uint256 marketId, uint256 passValue, uint256 failValue) {
       // Reports payouts to CTF1155
       uint256[] memory payouts = passValue > failValue ? [1, 0] : [0, 1];
       ctf1155.reportPayouts(market.questionId, payouts);
   }
   

   Status: ✅ COMPATIBLE - Resolves conditions for position redemption

Complete Market Lifecycle

1. Market Creation (ConditionalMarketFactory)
   ↓
   Creates CTF condition: conditionId = prepareCondition(...)
   Calculates position IDs: passPositionId, failPositionId
   ↓

2. Position Acquisition (CTF1155)
   ↓
   User splits collateral: splitPosition(collateral, conditionId, [1,2], amount)
   User receives ERC1155 tokens with passPositionId and failPositionId
   ↓

3. Order Creation (Off-chain with pmkt/1)
   ↓
   User creates signed order with:
   - makerAsset = address(ctf1155)
   - makerTokenId = passPositionId
   - takerAsset = collateralToken
   ↓
   Order propagated via pmkt/1 DevP2P network
   ↓

4. Order Filling (PredictionMarketExchange)
   ↓
   Taker calls fillOrder(order, signature, amount)
   Exchange verifies signature and transfers:
   - CTF position from maker to taker
   - Collateral from taker to maker
   ↓

5. Market Resolution (ConditionalMarketFactory)
   ↓
   Oracle resolves: resolveMarket(marketId, passValue, failValue)
   Reports payouts to CTF1155: reportPayouts(questionId, [1, 0] or [0, 1])
   ↓

6. Position Redemption (CTF1155)
   ↓
   Winners redeem: redeemPositions(collateral, conditionId, [winningIndex])
   Receive collateral payout
