The following smart contract is the THORChain_Router contract, which is responsible for handling deposits, transfers, and allowances of assets between different vaults and routers in the THORChain network. It includes functions for depositing assets, transferring allowances, transferring assets out, and returning vault assets. The contract also includes a non-reentrant modifier to prevent reentrancy attacks.
