Tried this (immediately firing a chainChanged event after approving the session), but Privy still requests a signature for the first chain in the optionalChains list (arbitrum). Is there a way to signal support for all optionalChains but have Privy choose the correct one for signing?

You can verify it is a TBA by computing the TBA address with the expected input values and comparing it with the actual address. The alternative would be to pre-compute the addresses for all/a subset of TBAs and index them

Very cool - had been wondering if there was an easy way to check for opcode support like this

Excited to roll out cross-chain support for TBAs today! So many cool use cases to be built now that your NFT can do anything on any chain https://twitter.com/tokenbound_/status/1768323785739141449

That said, this approach is ultimately working around not being able to render an iframe

Mostly (a) using dynamically generated SVGs because it's more convenient than rendering a png/jpeg.

That's awesome! Would love to contribute. Would be ideal if compatible with react + viem

Big fan of callthis :) Mostly looking for a front end library I could include in projects that need an embedded tx builder interface

Are there any good libraries for turning an ABI into a form?

Frame behavior question - it seems like the url included in the signed message when a button is clicked is always the original url of the frame, not the post_url. Is this expected? Is there any way to include the post_url in the signed data?

Mina is the closest I've seen to this. Doesn't it use a curve-based signature scheme for accounts though? I'm wondering if replacing curve-based signature verification with hash-based proof verification might result in simpler / cheaper / faster proofs.

Is anyone working on zk-based consensus? Intuitively it seems like you could replace zk-unfriendly signatures in consensus algorithms with (recursive) proofs of pubkey = hash(privatekey, data) using a zk-friendly hash, which would enable much cheaper / faster proofs.

I don't see why not! Assuming @paragraph supports ERC-1271 signatures it should work with TBAs out of the box.

ERC6551 accounts can execute operations (calls where msg.sender == account), but cannot originate transactions (calls where tx.origin == account). This is the same behavior as any other smart contract account.
