4.1.3 AgglayerManager

AgglayerManager al-v0.3.1 → v1.0.0

1. Overview

The AgglayerManager contract is the renamed and refactored version of PolygonRollupManager.

2. Key Changes from PolygonRollupManager

2.1 Version Interface Implementation

New Feature:

The contract now implements IVersion interface, adding:

contract AgglayerManager is
    // ... existing inheritance
    IVersion  // New interface
{
    // New version function
    function version() external pure returns (string memory) {
        return ROLLUP_MANAGER_VERSION;
    }
}

2.2 Version String Update

Version Constant: - Before: "al-v0.3.1" - After: "v1.0.0"

2.3 New Aggchain-Specific Update Logic

Major Enhancement: The updateRollup function now includes specialized logic for ALGateway rollup types:

Previous Logic:

function updateRollup(
    ITransparentUpgradeableProxy rollupContract,
    uint32 newRollupTypeID
) external {
    // Check admin of the network is msg.sender
    if (IPolygonRollupBase(address(rollupContract)).admin() != msg.sender) {
        revert OnlyRollupAdmin();
    }

    // Check all sequenced batches are verified
    if (rollup.lastBatchSequenced != rollup.lastVerifiedBatch) {
        revert AllSequencedMustBeVerified();
    }
}

New Enhanced Logic:

function updateRollup(
    ITransparentUpgradeableProxy rollupContract,
    uint32 newRollupTypeID
) external {
    RollupData storage rollup = _rollupIDToRollupData[
        rollupAddressToID[address(rollupContract)]
    ];

    if (rollup.rollupVerifierType == VerifierType.ALGateway) {
        // NEW: Aggchain-specific validation

        // Check aggchain manager is msg.sender
        if (
            IAggchainBase(address(rollupContract)).aggchainManager() !=
            msg.sender
        ) {
            revert OnlyAggchainManager();
        }

        // Check AGGCHAIN_TYPE compatibility
        if (
            IAggchainBase(address(rollupContract)).AGGCHAIN_TYPE() !=
            IAggchainBase(
                rollupTypeMap[newRollupTypeID].consensusImplementation
            ).AGGCHAIN_TYPE()
        ) {
            revert UpdateNotCompatible();
        }
    } else {
        // Original logic for non-ALGateway rollups
        if (
            IPolygonRollupBase(address(rollupContract)).admin() !=
            msg.sender
        ) {
            revert OnlyRollupAdmin();
        }

        if (rollup.lastBatchSequenced != rollup.lastVerifiedBatch) {
            revert AllSequencedMustBeVerified();
        }
    }
}

2.4 New Access Control Logic

Key Changes:

1. Aggchain Manager Check: For ALGateway rollups, validates that msg.sender is the aggchain manager instead of the admin
2. AGGCHAIN_TYPE Compatibility: Ensures that rollup types are compatible by checking their AGGCHAIN_TYPE
3. Conditional Logic: Maintains backward compatibility for non-ALGateway rollups

2.5. New Error Types

Added Error: - OnlyAggchainManager() - Thrown when a non-aggchain-manager tries to update an ALGateway rollup - UpdateNotCompatible() - Thrown when trying to update to an incompatible AGGCHAIN_TYPE
