# Unified Deposit Address

### Overview

Unified Deposit Address (UDA) is a cross-chain API solution that enables crypto applications to onboard users from any blockchain network using any supported asset. By providing a single deposit address deployed across multiple chains, UDA eliminates the friction of manual bridging and chain-specific asset requirements.

Traditional crypto applications face significant user acquisition challenges:

* **Chain Lock-in**: Users must bridge assets from different chains where they hold funds to the application's chain before they can start using the app
* **User Confusion**: Users often send incorrect assets to wrong addresses on incompatible chains and end up losing funds
* **Complex User Journey**: Multiple transactions and additional steps create friction in the onboarding process
* **Reduced Conversion**: Technical barriers like manual bridging prevent users from trying new apps

### Solution

UDA provides a **single, unified deposit address** deployed across multiple blockchain networks. When users send any supported asset to this address, the system automatically:

1. **Swaps** the deposited asset to the required token
2. **Teleports** the converted funds to the specified destination chain
3. **Delivers** the final asset to the user's wallet on the target network

### How It Works

#### Example

**Scenario**: Polymarket requires USDC on Polygon

* **User Holdings**: 10 USDT  on Avalanche
* **Action**: User simply transfers USDT to the unified deposit address
* **Result**: USDT is automatically converted to USDC and delivered to user's Polygon wallet

**Outcome:** User can immediately start trading on Polymarket without bridging or relying on third party applications to onboard to Polymarket.
