+### Gasless USDC Transfers
+
+To transfer USDC without needing to hold ETH for gas, you can use the `transfer` method with the `gasless` option set to `true`.
+
+```ruby
+# Create a new wallet w3 to transfer funds to.
+w3 = u.create_wallet
+
+puts "Wallet successfully created: #{w3}"
+
+t = w1.transfer(0.00001, :usdc, w3, gasless: true).wait!
