From 2d033e98fba393a12d1dfb9ef8759004f83c8604 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 5 Feb 2026 01:42:12 +0000 Subject: [PATCH 1/4] feat: add FastCommitManager with signed commit optimization Implements a new commit-reveal flow that reduces transactions from 3 to 2: - Normal flow: commit -> reveal -> reveal (3 TX) - Fast flow: signedCommit+reveal -> reveal (2 TX) The revealing player can submit the committing player's EIP-712 signed commitment along with their own reveal in a single transaction. This removes the need for the committing player to make an on-chain commit. Changes: - DefaultCommitManager: expose internal storage and helpers for extension - SignedCommitLib: EIP-712 type hash library for signed commits - FastCommitManager: extends DefaultCommitManager with revealMoveWithOtherPlayerSignedCommit() - Comprehensive test suite including timeout compatibility and security tests - Gas benchmark tests for cold/warm storage access patterns Fallback: If the revealing player doesn't publish the signed commit, the committing player can still use the normal commitMove() flow. https://claude.ai/code/session_012MZ9EeP4GD7GXEmu1S5xL1 --- src/DefaultCommitManager.sol | 25 +- src/FastCommitManager.sol | 175 ++++++ src/lib/SignedCommitLib.sol | 36 ++ test/FastCommitManager.t.sol | 1142 ++++++++++++++++++++++++++++++++++ 4 files changed, 1376 insertions(+), 2 deletions(-) create mode 100644 src/FastCommitManager.sol create mode 100644 src/lib/SignedCommitLib.sol create mode 100644 test/FastCommitManager.t.sol diff --git a/src/DefaultCommitManager.sol b/src/DefaultCommitManager.sol index 98ad6bae..9b293e2d 100644 --- a/src/DefaultCommitManager.sol +++ b/src/DefaultCommitManager.sol @@ -9,9 +9,9 @@ import {ICommitManager} from "./ICommitManager.sol"; import {IEngine} from "./IEngine.sol"; contract DefaultCommitManager is ICommitManager { - IEngine private immutable ENGINE; + IEngine internal immutable ENGINE; - mapping(bytes32 battleKey => mapping(uint256 playerIndex => PlayerDecisionData)) private playerData; + mapping(bytes32 battleKey => mapping(uint256 playerIndex => PlayerDecisionData)) internal playerData; error NotP0OrP1(); error AlreadyCommited(); @@ -32,6 +32,27 @@ contract DefaultCommitManager is ICommitManager { ENGINE = engine; } + /// @notice Get the player index for a given player address in a battle + /// @param battleKey The battle identifier + /// @param player The player address + /// @return playerIndex 0 for p0, 1 for p1 + function _getPlayerIndex(bytes32 battleKey, address player) internal view returns (uint256) { + address[] memory players = ENGINE.getPlayersForBattle(battleKey); + return (player == players[0]) ? 0 : 1; + } + + /// @notice Store a commitment for a player (used by FastCommitManager for signed commits) + /// @param battleKey The battle identifier + /// @param playerIndex The player index (0 or 1) + /// @param moveHash The move hash to store + /// @param turnId The current turn ID + function _storeCommitment(bytes32 battleKey, uint256 playerIndex, bytes32 moveHash, uint64 turnId) internal { + PlayerDecisionData storage pd = playerData[battleKey][playerIndex]; + pd.lastCommitmentTurnId = uint16(turnId); + pd.moveHash = moveHash; + pd.lastMoveTimestamp = uint96(block.timestamp); + } + /** * Committing is for: * - p0 if the turn index % 2 == 0 diff --git a/src/FastCommitManager.sol b/src/FastCommitManager.sol new file mode 100644 index 00000000..26e202d5 --- /dev/null +++ b/src/FastCommitManager.sol @@ -0,0 +1,175 @@ +// SPDX-License-Identifier: AGPL-3.0 +pragma solidity ^0.8.0; + +import {DefaultCommitManager} from "./DefaultCommitManager.sol"; +import {EIP712} from "./lib/EIP712.sol"; +import {ECDSA} from "./lib/ECDSA.sol"; +import {SignedCommitLib} from "./lib/SignedCommitLib.sol"; +import {IEngine} from "./IEngine.sol"; +import {IValidator} from "./IValidator.sol"; +import {CommitContext} from "./Structs.sol"; + +/// @title FastCommitManager +/// @notice Extends DefaultCommitManager with optimistic commit flow using signed commitments +/// @dev Allows the revealing player to submit the committing player's signed commitment +/// along with their own reveal in a single transaction, removing the need for the +/// committing player to make an on-chain commit transaction. +/// +/// Normal flow (3 transactions): +/// 1.
