Mini Apps

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

As an aside: I'd like to see Warpcast (and any wallet that supports mini apps) adopt a standard for common and well-understood onchain actions, e.g. sending USDC.

So instead of 1) Approve 2) Send as two pop ups, consolidate into one with clear language (and assuming you're doing the security scanning and offering a more advanced user the ability to inspect).

Imagine having to swipe your credit card twice when paying for a coffee.

do any of you know? 

we’re trying to make a mini app USDC transaction smoother so that a token approval and mint are only one transaction instead of 2

Making cross-chain payments easy. Follow @tusharsoni.eth for updates or visit paywithglide.xyz

Yes. Use something like @paywithglide or build your own.

You send USDC to an address (no approve). And then a listener executes the actual contract TX once USDC is received.

I want to make a simple mint frame that accepts erc20 payments for mints. Aiming for one click.

IMO the approval step adds confusion for first timers. 

Is there an elegant way to transfer an erc20 to a contract and then check that msg.sender has sent the appropriate amount before minting? 

All roads I've thought through so far lead to the check offchain. I'm ok with that but wondering if someone has done something similar and can help me out!
