We shouldn't sacrifice user experience for nanny security.

I agree. UX is top priority.

I can't recall off the top of my head where I read or heard this, but it goes something along the lines:

The app shouldn't adapt to the limitations of the blockchain at the expense of UX but the blockchain should cater to the needs of real world apps.

That said, I think Keychain is an awesome way to bridge that gap. It would be beneficial if it was highlighted more, like how MetaMask has become ubiquitous.

This is from a section of their API documentation:

Sites can request that the extension sign and broadcast a transfer operation for STEEM or SBD. Note that a confirmation will always be shown to the user for transfer operations and they cannot be disabled.

Perhaps we could propose this to them to support tips/donations:

• provision a setting for tip enabled site (think trusted sites)
• allow unconfirmed transfers on that site only, that follow these rules:
  • only transfers that follow the memo protocol (can be implemented using a regex check)
  • must be below a user set maximum (optional)
