Crane Aerodrome

Crane Aerodrome Integration

Crane provides comprehensive Aerodrome v1 and Slipstream integration with services, stubs, and test infrastructure.

Components

Pool Types

Aerodrome has two pool types with different AMM curves:

Quick Start: Volatile Pool Swap

import {AerodromServiceVolatile} from "@crane/contracts/protocols/dexes/aerodrome/v1/services/AerodromServiceVolatile.sol";
import {AerodromeRouterAwareRepo} from "@crane/contracts/protocols/dexes/aerodrome/v1/aware/AerodromeRouterAwareRepo.sol";

contract MyVault {
    function swap(IERC20 tokenIn, IERC20 tokenOut, uint256 amount) external {
        IRouter router = AerodromeRouterAwareRepo._router();
        IPoolFactory factory = router.defaultFactory();
        IPool pool = IPool(factory.getPool(address(tokenIn), address(tokenOut), false));

        AerodromServiceVolatile._swapVolatile(
            AerodromServiceVolatile.SwapVolatileParams({
                router: router,
                factory: factory,
                pool: pool,
                tokenIn: tokenIn,
                tokenOut: tokenOut,
                amountIn: amount,
                recipient: address(this),
                deadline: block.timestamp
            })
        );
    }
}

Service Operations

Volatile Pool Service

// Simple swap
function _swapVolatile(SwapVolatileParams memory params) internal returns (uint256 amountOut);

// Swap and deposit in single transaction
function _swapDepositVolatile(SwapDepositVolatileParams memory params) internal returns (uint256 lpOut);

// Withdraw and swap to single token
function _withdrawSwapVolatile(WithdrawSwapVolatileParams memory params) internal returns (uint256 amountOut);

// Quote optimal swap amount for balanced deposit
function _quoteSwapDepositSaleAmtVolatile(params) internal view returns (uint256 saleAmt);

Stable Pool Service

Same function signatures with Stable suffix:

function _swapStable(SwapStableParams memory params) internal returns (uint256 amountOut);
function _swapDepositStable(SwapDepositStableParams memory params) internal returns (uint256 lpOut);

Route Building

IRouter.Route memory route = IRouter.Route({
    from: address(tokenIn),
    to: address(tokenOut),
    stable: false,  // true for stable pools
    factory: address(factory)
});

IRouter.Route[] memory routes = new IRouter.Route[](1);
routes[0] = route;

router.swapExactTokensForTokens(
    amountIn,
    amountOutMin,
    routes,
    recipient,
    deadline
);

AwareRepo Pattern

// Initialize during deployment
AerodromeRouterAwareRepo._initialize(router);

// Access in operations
IRouter router = AerodromeRouterAwareRepo._router();

Testing

import {TestBase_Aerodrome_Pools} from "@crane/contracts/protocols/dexes/aerodrome/v1/test/bases/TestBase_Aerodrome_Pools.sol";

contract MyTest is TestBase_Aerodrome_Pools {
    function setUp() public override {
        super.setUp();
        // aerodromeRouter, aerodromeFactory, voter, etc. available
    }

    function test_swap() public {
        // Create pool and test
    }
}
