Crane Aerodrome Integration

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

Components

Component Location Purpose
AerodromServiceVolatile services/AerodromServiceVolatile.sol Volatile pool operations (xy=k)
AerodromServiceStable services/AerodromServiceStable.sol Stable pool operations (x^3y+xy^3=k)
AerodromeRouterAwareRepo aware/AerodromeRouterAwareRepo.sol Router dependency injection
AerodromePoolMetadataRepo aware/AerodromePoolMetadataRepo.sol Pool metadata storage
TestBase_Aerodrome test/bases/TestBase_Aerodrome.sol Full protocol deployment
TestBase_Aerodrome_Pools test/bases/TestBase_Aerodrome_Pools.sol Pool creation helpers
SlipstreamRewardUtils slipstream/SlipstreamRewardUtils.sol CL reward calculations

Pool Types

Aerodrome has two pool types with different AMM curves:

Type Curve Use Case Service
Volatile xy = k ETH/USDC, volatile pairs AerodromServiceVolatile
Stable x^3y + xy^3 = k USDC/USDT, stablecoin pairs AerodromServiceStable

Quick Start: Volatile Pool Swap

solidity
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

solidity
// 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:

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

Route Building

solidity
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

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

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

Testing

solidity
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
    }
}
