# FlashSwapsProxy contract

This is a helper contract. It is only needed in case of [***flash\_swap***](/smart-contracts/dex-2.0/dexcore-contract/entrypoints-overview/dex-entrypoints/swap.md) entrypoint call. It accepts a user's lambda from [***DexCore***](/smart-contracts/dex-2.0/dexcore-contract.md) contract and executes it.

This implementation is due to the fact that users' lambdas can be malicious for a [***DexCore***](/smart-contracts/dex-2.0/dexcore-contract.md) contract. And to avoid this, the execution of the users' lambdas is transferred to this ***FlashSwapProxy*** contract.
