CorkAdapter

Slippage-protected write operations for Cork Protocol integration

Address: 0xCCcCcCCCcccCBaD6F772a511B337d9CCc9570407 (same on all chains)

CorkAdapter wraps CorkPoolManager operations with slippage protection and deadline checks via Morpho Bundler3. Use this contract for all write operations in production integrations.

While you can interact with CorkPoolManager directly, it does not provide slippage or deadline protection. Use CorkAdapter for production integrations.

Common Parameters

Every CorkAdapter function takes a params struct. These fields appear across all operations:

Field	Type	Description
poolId	bytes32	The MarketId identifying which Cork Pool to interact with
receiver	address	The address that receives the output tokens
deadline	uint256	Unix timestamp after which the transaction reverts. A reasonable default is block.timestamp + 300 (5 minutes).

Slippage fields vary per operation — each function has either a min*Out field (minimum acceptable output) or max*In field (maximum acceptable input). Set these using the corresponding preview* function on CorkPoolManager, adjusted for your slippage tolerance. For example, for 0.5% slippage on a deposit:

const expectedShares = await previewDeposit(marketId, amount)
const minSharesOut = expectedShares * 995n / 1000n // 0.5% slippage
