Here is a new demo of our hardware wallet Keystone - https://twitter.com/KeystoneWallet/status/1415316932954255362
Basically we put a big pack of ABIs (thanks to Sourcify’s work) into microSD card and insert the card into the device. Then the device will be able to use the ABI to decode complex DeFi transactions.
What even cooler is that we allow user to customize his own ABI into the microSD card.
This will enable the user to fully verify a DeFi transaction on his hardware wallet.
Please let me know if you have any comments about this.
