building /onceupon this week we shipped something we haven't announced yet, but here's some early alpha for this channel. we shipped https://contract.cool, an app for finding trending contracts in your farcaster network. under the hood, it uses our new trending api for the past seven days of data.

SIWE, SIWF, SIWSW (Coinbase Smart Wallet) to support logging into apps as a contract: can we get more adoption of ERC-1271 this time around? or find a simpler standard? or is sending a tx to auth with every app sufficiently realistic on L2s and L3s? (probably not) or does CB SW already have this solved somehow?

these days we're all in on prosumer features, often asking "what would linear do?" we used to hide options under a "more" menu for fear of overwhelming newcomers. but we're building for power users. if you invest time in learning /onceupon, now you'll have more options with more info density, all one click away.

if I change my location to LA, can I change it back to *no location* after that? or would I be locked into being a location person from now on?

it will be cool to see what people do with this public *farcon summit pass holders* group going into next week! nft mint allowlists, a convenient way to slide into direct casts, data analysis, more frames using this list, etc.

when a mint happens via a transaction frame in warpcast, we now show that on once upon. we do this by looking for the calldata suffix 0xfc000023c0. here's an example tx https://www.onceupon.xyz/0x851e444453401a58e95c74d860c18580ff18b42ba6645d95ba86d3cf405de3fb

PSA 📣 we updated our API endpoints from v1 to v2 to make breaking changes. feel free to DC me with any questions. in most cases, changing from v1 to v2 should "just work". we will not be supporting v1 other than our frames endpoints that return html, which support both v1 and v2.
