SyrupRouter

Lightweight router for lender integrations with Syrup pools. Provides stable entry points for first‑time authorized deposits (with optional ERC‑2612 permits) and subsequent deposits, and exposes the underlying pool, manager, and permission manager addresses.

Functions

Returns the underlying asset of the ERC‑4626 vault (pool).

    function asset()
        view
        returns (
            address asset
        );

pool

Returns the Maple Pool (ERC‑4626 vault) address.

    function pool()
        view
        returns (
            address pool
        );

poolManager

Returns the Pool Manager address.

        view
        returns (
            address poolManager
        );

poolPermissionManager

Returns the Pool Permission Manager address.

    function poolPermissionManager()
        view
        returns (
            address poolPermissionManager
        );

nonces

Returns the current nonce for the owner (used in authorization signatures).

        address owner
    )
        view
        returns (
            uint256
