# CTWrapper Interaction Guide

The `CTWrapper` is the primary entry point for converting Conditional Tokens (ERC1155) into tradeable ERC20 assets. This guide covers the key interactions for developers.

## Contract Addresses

For deployment addresses, please refer to the [Deployments](/contracts/addresses) page.

## Key Methods

### 1. Wrapping Tokens

To wrap tokens, you must first have the underlying ERC1155 tokens from the Conditional Tokens Framework.

```solidity theme={null}
function wrap(bytes32 conditionId, uint256[] calldata amounts) external;
```

**Parameters:**

* `conditionId`: The unique identifier of the condition (question).
* `amounts`: An array of amounts to wrap for each outcome slot.

**Example (Ethers.js):**

```javascript theme={null}
const wrapper = new ethers.Contract(mockWrapperAddress, wrapperAbi, signer);
await wrapper.wrap(conditionId, [amountYes, amountNo]);
```

### 2. Unwrapping Tokens

Unwrapping burns the ERC20 tokens and returns the underlying ERC1155s.

```solidity theme={null}
function unwrap(bytes32 conditionId, uint256 amount) external;
```

**Note**: In the current implementation, `unwrap` typically unwraps a specific amount of *all* outcome tokens associated with that condition back to the user's wallet.

### 3. Deploying Converted Tokens

Before a condition can be traded, its ERC20 representations must be deployed.

```solidity theme={null}
function deployToken(bytes32 conditionId, string calldata name, string calldata symbol) external returns (address);
```

* **Determinism**: This uses `CREATE3`, so the address is deterministic based on the `conditionId`.
* **First Settler**: The first person to call this sets the name/symbol, but the address is constant.

## Event Listeners

Listen for `TokenDeployed` events to discover new markets.

```solidity theme={null}
event TokenDeployed(
    bytes32 indexed conditionId, 
    address lenToken, 
    bytes32 salt, 
    string name, 
    string symbol
);
```
