# Value Swaps
"Buy $100 worth of DEGEN"
"Purchase $50 of ETH"

# Percentage Swaps
"Swap 50% of my ETH to USDC"
"Sell 25% of my DEGEN"

# Chain-Specific

"Exchange 100 USDC for WETH on Ethereum"

ERC20 Approval Handling

For ERC20 swaps (selling tokens other than ETH), approval is required before the swap.

const result = await client.promptAndWait({
  : ,
});

 swapTx = result.?.( tx. === );


 (swapTx?..) {
  
   wallet.(swapTx..);
}


 wallet.(swapTx..);
