Swapping

QSafe Wallet’s swap feature simplifies decentralized token exchanges across multiple blockchains. Here's a breakdown of how it works, using the screenshots attached as examples:

1. Swap Interface Overview

The swap screen allows you to convert one cryptocurrency into another (e.g., POL → USDC on Polygon). Key components include:

• Token Selection:

  • Input Token: Select the token you want to spend (e.g., POL).

  • Output Token: Choose the token you want to receive (e.g., USDC).

• Amount Input: Enter the quantity of the input token (e.g., 0.0001 POL).

• Network Selection: Specify the blockchain for the swap (e.g., Polygon).

• Recipient Address: Optionally set a destination address for the received tokens.

• Preview Button: Simulate the swap to view real-time rates, fees, and slippage.

2. How It Works Under the Hood

1. Price Aggregation: Q Safe Wallet queries decentralized exchanges (DEXs) and aggregators to find the best possible rate for your swap. For example, in the screenshot, swapping 0.0001 POL yields 0.000021 USDC.

2. Gas Fee Estimation: The wallet calculates the network fee (gas) required to execute the transaction.

3. Slippage & Risk Management:

   • Slippage Tolerance: The maximum acceptable price change during execution (default 0.5%).

   • Minimum Received: Ensures you get at least the specified amount even if prices fluctuate.

4. Security Checks:

   • Validates if you have enough funds to cover both the swap amount and gas fees .

   • Alerts you if funds are insufficient (as shown in the error message).
