# EeseeExpress

## EeseeExpress

*Squid Router extension that adds permit support and the ability to use ERC20 tokens from contract's balance.*

### AddressWithChain

```solidity
struct AddressWithChain {
  string chain;
  address _address;
}
```

### TokenData

```solidity
struct TokenData {
  contract IERC20 token;
  uint256 amount;
  bytes permit;
}
```

### squid

```solidity
contract ISquidRouter squid
```

*Contract address for Squid Router.*

### InvalidConstructor

```solidity
error InvalidConstructor()
```

### InvalidRecipient

```solidity
error InvalidRecipient()
```

### callBridgeCall

```solidity
function callBridgeCall(struct EeseeExpress.AddressWithChain squidRouter, string tokenToSymbol, struct EeseeExpress.TokenData tokenFrom, struct ISquidMulticall.Call[] sourceCalls, struct ISquidMulticall.Call[] destinationCalls, address refundRecipient, bool isExpress) external payable
```

*Send tokens to another chain with Squid and call multicall on both chains. Note: The caller must either own those tokens, or have them transfered to this contract beforehand. !WARNING! Never send any tokens to this contract from an EOA, or by contract in a separate transaction or they will be lost. Only send funds to this contract if you spend them by calling callBridgeCall function in the same transaction.*

| ---------------- | ------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| squidRouter      | struct EeseeExpress.AddressWithChain | - Struct with destination chain and the address of SquidRouter on that chain.                                                                                                 |
| tokenToSymbol    | string                               | - Token symbol to transfer to {squidRouter.chain}.                                                                                                                            |
| tokenFrom        | struct EeseeExpress.TokenData        | - Token to collect from sender or use from this contract's balance with abi-encoded permit containing approveAmount, deadline, v, r and s. Set to empty bytes to skip permit. |
| sourceCalls      | struct ISquidMulticall.Call\[]       | - Calls to make on this chain.                                                                                                                                                |

## Inherited from EeseePausable

### pause

```solidity
function pause() external virtual
```

*Called by the PAUSER\_ROLE to pause, triggers stopped state.*

### unpause

```solidity
function unpause() external virtual
```

*Called by the PAUSER\_ROLE to unpause, returns to normal state.*

## Inherited from EeseeRoleHandler

## Inherited from Pausable

### paused

```solidity
function paused() public view virtual returns (bool)
```

*Returns true if the contract is paused, and false otherwise.*

### Paused

```solidity
event Paused(address account)
```

*Emitted when the pause is triggered by `account`.*

### Unpaused

```solidity
event Unpaused(address account)
```

*Emitted when the pause is lifted by `account`.*

## Inherited from ERC2771Context

### isTrustedForwarder
