Hey @spacoin, thanks for watching the video, gasless wallet transfer is impossible unfortunately because the only person that have access to the wallet fund (native token ETH/BNB/MATIC/AVAX/FTM) is the wallet itself. Therefore any transfer of funds to other address will only possible to be executed by the wallet itself.
On the other hand, gasless transaction that is executed to an EIP-2771 compliant smart contract can give access to relayer (such as Biconomy) to execute transaction on the user behalf, which ultimately enable the gasless transaction.
REMEMBER: gasless does not mean free (no gas fees paid)
However, if you want to transfer tokens such as ERC20/721/1155, it might be possible to do gasless transaction on it by defining a simple smart contract that you must approve first then transfer it on behalf of the user wallet.
