Swap Fees Drop, Casting Changes, and Typos as Proof of Humanity: GM Farcaster ep276

New: Lightning fast swaps We made our swaps a lot faster. They now take 2-3s on average. This one took barely a second. Another small step towards making this the best wallet to trade with.

I find the wallet integration on Farcaster very well done. This is what it should look like on all social media apps in the future. Hard to unsee the future once I see it here on Farcaster. Even Telegram could have done a better job of making its wallet more prominent instead of hiding it in the Settings.

WE WON THE FREAKING EMMY this is a first for a crypto project i think skddjsjdijdkxjcdjnxjxj

Swap fees now at 0.15% on Ethereum chains and 0% on Solana. We were able to lower fees by another 40% and we're passing the savings along to you.

Pro Trading is out to all users. Restart to get the latest. Fees are even lower for Pro users. We now charge 0% on solana and 0.15% on eth chains (the fees go to our swap providers). Help us test the new experience! If you swap $100 this week, you'll earn an extra 1000 points on the leaderboard.

I want to produce a show that’s like the old Newlywed Game, but for cofounders building on Farcaster. We would have a few sets of cofounders on stage (the “couples”) and we’d ask questions to one that we had previously asked the other, and see how well their answers match. Whichever couple gets the most matches, wins Prizes could be put up by companies in the farcaster stack, like free 3 month subscription to privy or neynar, or X dollars worth of amps credit Is there interest in this? Which couples, I mean cofounders, should we invite first?

** Rewards Leaderboard Results ** * Well, we've come full circle. @ted was #2 in the first-ever Rewards cast I did (see quoted cast) and now she's back to take the #1 spot as a mere mortal Farcaster. Congrats! 💜 * @erica returns to the top 10 after a hiatus on her pear-less trip to Europe 🐱 ; & @accidentalboymom nips Bert for #3 * Some familiar faces in the top 10, but always seems right to @july find his way into the top 10 at #9 * Congrats to @0ffline for #12, even though not top 10 a great week; also seems like formerly 'too hot for the leaderboard' @jessyjeanne has had a breakthrough and becoming a regular in the top 30 at #23 * @stevedylandev at #18 seems like their hightest rank & @rubinovitz at #27 maybe their highest (?) * Meme-coveted #69 goes to @danicaswanson who has started to move up a few tiers in the last couple weeks * Keep an eye out for first-timers who get excited to get their first $3 or $5 & celebrate with them 🎈

Stripe is launching a L1 with Paradigm called Tempo Circle is launching a L1 with Informal Systems called Arc Feels like we’re back in the enterprise blockchain era

It's 2030 You're a merchant receiving payment from a customer. They pay with USDC on CircleChain but your payment termainl only receives StripeUSD on StripeChain. But once you get StripeUSD, you want to transfer it to your account with Bank of America, so you need to transfer it to BofAUSD on BofAChain. But wait, you go and pay your supplier. The problem is, they custody with JPMorgan. So then you need to get your BofAUSD on BofAChain to JPMorganUSD on JPMorganChain. But JPMorganChain is permissioned, so you need to route it through a special intermediary... and so on Is this the future we're headed toward?

Working on making the Token Page better on mobile. What are your top requests?

I agree with this. As crypto is a community. That grows by millions every year. So what we build for the base today… …is used by normies tomorrow. Thus we can be all-in on crypto. In a user-friendly way, of course. In a high-trust way, too! But also in a straightforward way. Because the world is going onchain.

What’s the wildest sponsorship or stunt we could pull off together that would put $DEGEN in front of millions? Drop your ideas 👇🎩

Will answer your specific questions first, then share some more on safety. These are gonna be long so will reply separately for each. WALLET ACCESS > If we can grant wallet access to mini apps easily in Farcaster, why can’t we revoke them just as easily? "Wallet access" is an overloaded term. If you're using a mini app, what can it actually do with your wallet? 1. Read token balances. Farcaster is a public social network and your token balances are all public onchain. So really anyone has this capability. But when you use a mini app it does know about your wallet address and the tokens in it, as well as your Farcaster identity. 2. Make requests to do things. Mini apps can ask your wallet to send a transaction or sign a message, but you the human user must always approve or reject them. That doesn't mean they can't try to trick you! But you are always in the loop. So how can you tell if a request is legit? The first screenshot here is Tortoise by @mattlee requesting a transaction to mint a song. When a mini app requests a transaction we scan it with blockaid.io and show you what it will do. In this case I'm sending $4.24 of ETH and getting back an NFT. We also show the domain (tortoise dot studio) and the mini app context (you can see this is Tortoise and it was created by Matt) You can also tap into "Advanced" and see more technical information about exactly what it's doing. (See the second screenshot). This is very useful if you're suspicious of a particular request but not that readable to a normal human. If the request is flagged as malicious we block it. If it's flagged as suspicious we show a warning. We do our best here, but transaction scanning is never perfect: there are always both false positives and false negatives. (In fact, I think we get much more grief from developers for false positives than anything else). 3. Request token approvals. This is really a special case of #2 but since it's so common and can be more dangerous it deserves its own category. One kind of request a mini app can make is asking you to give it an "approval" to spend some amount of a token. This can be a limited or unlimited amount. This pattern is deeply baked into crypto and very much an original sin of crypto UX. The third screenshot here is Crowdfund asking me to approve spending 5 USDC as a donation. If you see an app ask for an unlimited approval here, that's usually a red flag. Of all the things a mini app can do, you should be most careful about approving requests for token approvals. It's the only thing that allows an app to "do something" with the money in your wallet when you're not physically there. But there are many legitimate use cases for approvals. For example, approvals are what enable Tipn and Noice to send tips on your behalf. There's nothing to "disconnect" or "revoke" for 1 and 2. For 3, you can check and revoke approvals with other mini apps (will share one below). Viewing/revoking approvals is something we can and should build in to the app/wallet and I think we will soon.

Happy birthday, Base. Two years in. Still day one.

Please forgive my uninformed, non-crypto person questions, but now I’m very curious: 1. If we can grant wallet access to mini apps easily in Farcaster, why can’t we revoke them just as easily? 2. Why isn’t there some kind of “verified” badge yet in the mini app ecosystem to mark developers who’ve gone through a vetting process? Currently, to my beginner eyes, all apps look equal. I’m personally going to exercise a lot more caution going forward. But, given the simultaneous push for mini apps and new users, additional security features feel critical for growth in both. I’m feeling a little spooked honestly after using a mini app that felt like it was for a good cause. I’m surprised I missed a lot of information shared in the thread below, despite being on Farcaster every day for a few months now. More context:

WHAT WE SHIPPED IN THE LAST TWO WEEKS ON @baseapp.base.eth top focus has been on performance, polish, and bugs. 👇 Big improvements to videos: Vertical videos feel better, all videos have timestamps overlays, auto-resume when you swipe back, and have overall smoother playback. Tighter convos: Inline replies keep you in the feed and mentions now have better support for long usernames. Cleaner coin creation: Ticker spacings are fixed and emojis are now supported. Better mini-apps: Open one mini-app from another, enjoy fast context data (<50 ms!), full safe-area handling on every device, and (this is big) BasePay is built in now. Fit and finish on payments: Tapping your balance now auto-fills max, error messages are cleaner, and you can toggle off incoming requests. Faster and better everything: Faster feed loads, better Android stability, easier onboarding, and lots of keyboard fixes for replies. What’s next: Inline comment replies, pinch-to-zoom photos, 1GB+ uploads, and invite codes.

Helping to show off how cool Farcaster is at the Ethereum NYC World of App events next week https://x.com/ljxie/status/1953910219076927628

i'm excited about @coinbase.farcaster.eth’s DEX launch because it puts @base.base.eth builders on a level playing field base is for everyone, but because of the antiquated listings process, that didn't always feel true now it is: and it's up to builders to earn the attention with hard work. onwards!

Millions of assets. One Coinbase app. → Every asset on base → Faster and easier access to onchain trading → Tokens go from launch to available on Coinbase in moments All available in the same Coinbase app with DEX trading. Rolling out now, starting in the U.S. (ex. NY).

They didn't spend that much money if you come to think of it https://paragraph.com/@0xd6ff56c5130dae8cfe57c0a608885a3b34f64f5b/the-popfi-pandemonium

I hate to say it but the Solana trenches are rinsed. The $pop wallet that FSH'd ~$22k was slowly selling over the past 24 hours after receiving multitudinous inbound transfers of the token from a number of accounts, all in denominations equivalent to roughly $950. This is a typical strategy to obfuscate the source of funds (Slerf tools has easy to use and cheap functions for this). The wallet never made a purchase of the actual token, it only received the tokens for free. It got impatient and dumped everything it held. Over the course it was more than 35% of the total supply of the token.
