The Apprentice Wizard

We’re heading to Seoul 🇰🇷 After a competitive Phase 1, builders from around the world are joining us for Build Week: 7 days of building, testing, and refining products with @world_chain_ Across this cohort, builders are exploring: ➡️Human-verified social and community apps ➡️Financial products built on proof of human ➡️Consumer apps designed for instant global distribution Let’s launch to 38M+ users!

As Sui expands, we need to keep track of who's shaping our on-chain landscape and how Tomorrow is the launch of hopdotfun phase 2, so before that I'd like to share some concerns with @HopAggregator team and the Sui community 👇 Do you remember this tweet? Hop initially launched with 0% fee, hyping everyone. This is pretty cool but obviously they have to make money in a way or another, so they charge a fee upon swaps to apps that integrate their sdk. So far so good. Charging the businesses instead of the individuals is a clever strategy. But things get shadier when you actually integrate the sdk. In the screenshot below, you can see at line 3 that I am setting 1 bps (0.01%) for the fee. I'm then swapping 0.01 SUI for USDC. But if we look on-chain (transparency, yay!), it's another story. This is the move function handling the fee. Here's how it works: 1. takes the coin 2. calculates the fee (v0 = coin.value() * fee) 3. splits the fee coin from the coin in (v1) 4. transfers half to Hop treasury 5. transfers other half to address specified So in our case it should pass a Coin with 10_000_000 value and 1 as the fee. But if we look at the transaction on-chain, we can see that the 3rd argument (2), which is the fee, has a value of 30 instead of 1. I tried again by changing to 5 but same result. However if I change to 300, it uses the right value. I couldn't find any info about this, the only docs they have is the readme on github that says 1bps is 0.01%. So what is happening here? Did Hop switch to a minimum fee of 0.3% and enforced it without telling anyone? Are there projects that are aware of it and keeping it quiet? Is it just a mistake? Idk but I'd love an answer. Both users and builders of those integrations are overpaying without knowing it. I mean it's fine to take whatever fee you think you need, but just be transparent! Depending on how the launch goes, I might post more info tomorrow to better understand the team and its mentality. I know many teams on Sui but this is one of the few I have very little details about and that's why I demand answers.
