"If you are not the primary venue for an asset (which Binance is not for USDe) then you should look at the price on the primary venue. If you are only looking at your own order book, you will liquidate too aggressively" TLDR: Pricing for pegged assets should involve both exchange level and external (via oracle) pricing. That's one of the key design decisions we made while building @MantisSwap: oracle-adjusted pricing custom AMM mechanics designed for pegged assets. Pushing the price below peg gets expensive fast -> harder to cause depegging -> LPs lose less money. Hyperliquid

Did Ethena Really Depeg? I’ve seen a lot of chatter about the Ethena depeg during the market mayhem this weekend. The story is that USDe briefly depegged to ~68c before recovering. Here’s the Binance chart everyone is quoting: But digging into the data and talking to a bunch of folks over last couple days, it's now clear this story is not correct. USDe did *not* depeg. First thing to understand about USDe: its most liquid venue is actually not on exchanges, it’s on Curve. There’s hundreds of millions of dollars of standing liquidity on Curve, while only tens of millions on any given exchange, including Binance. So if you just look at that chart of USDe on Binance, it looks like USDe depegged. But if you superimpose the other liquid venues for USDe, you get a different picture: We see here that while USDe wicked down on every CEX, it did not do so uniformly. Bybit briefly hit $0.95 then quickly recovered, yet Binance depegged a crazy amount and took forever to regain the peg. Curve meanwhile dipped a mere 0.3%. What explains this difference? Remember, every single exchange was under immense load on that day—it was the single largest liquidation event in crypto history. Binance was extremely unstable during this period, causing MMs to be unable to shift inventory because APIs were failing and withdrawals and deposits were bricked. Nobody was able to step in and arb. It’s like a fire broke out on Binance, but all of the roads were blocked and firefighters couldn’t make their way in. This caused a wildfire to break out on Binance, but pretty much everywhere else, that fire was immediately put out by bridging liquidity. (As Guy shows in his post, USDC also depegged a few cents temporarily on Binance due to the same general instability issues—liquidity just couldn’t get ferried in, but this wasn’t a depeg event for USDC either.) So OK. Unsurprising that while there’s API instability, prices on exchanges are wildly different because nobody can get inventory in. But why did it decline so much deeper on Binance than on Bybit? The answer is twofold—first, Binance did not have any primary dealer relationship with Ethena to be able to directly mint and redeem on-platform (Bybit and other exchanges have this integrated) which allows MMs to stay on-platform and still perform peg arbitrage. This is huge, as otherwise an MM has to take their money *out* of Binance, go do the Ethena peg arb, and then bring back their inventory. Nobody was doing that in a moment of crisis when APIs were failing (plus so many other coins were cratering). Second, Binance had their oracle poorly implemented and started liquidating positions they shouldn’t have—good liquidation mechanisms don’t trigger on flash crashes. If you are not the primary venue for an asset (which Binance is not for USDe) then you should look at the price on the primary venue. If you are only looking at your own order book, you will liquidate too aggressively. This caused Binance to start liquidating USDe as though it was worth $0.80 or whatever, which caused a cascade. This is a big part of the reason why Binance is refunding people who were liquidated on USDe (other exchanges AFAIK are not doing so)—they messed up by only looking at their own price instead of the true external price. So this was a Binance-specific flash crash, which better market structure could’ve prevented. USDe on its primary venue, Curve, was actually trading at a tight peg the entire day. This is really different from what you’d describe as a depeg. If you remember USDC in 2023 during the banking crisis, this is what an actual depeg looks like: During the banking crisis, USDC traded down on every single venue. There was *no* place where you could buy USDC for $1. Redemptions were literally halted, so $0.87 was the *true* price. That’s what a depeg means. This instead was a Binance-specific dislocation. It’s a big lesson for market infra, but critical to understand the nuance here if you are trying to draw inferences about USDe’s mechanism from this weekend. USDe was fully collateralized and worth $1 on its primary venue through the entire episode and actually increased its backing collateral over the weekend due to the price action. That said, this kind of market instability is ultimately good because it exposes lessons for the whole industry. Guy’s post below lays out how any exchange, including Binance, can avoid this kind of issue in the future. TL;DR: USDe did not depeg, Binance did.

What a time to be going live with what js probably the most unique points program on HyperEVM for @MantisSwap NFT communities already onboard: ✅ @PiPonHL@baldbrothers_@tinyhypercats@ADHD_HL And now Hypurr holders will also be included. Hypurrliquid
Hypurr NFTs have been deployed on the HyperEVM. Participants had the opportunity to opt in to receive a Hypurr NFT after the HyperEVM went live as part of the Genesis Event in November 2024. The HyperEVM launched in February 2025 as the general programmability interface to the Hyperliquid L1. The HyperEVM is not a standalone EVM. Rather, it allows developers to trustlessly tap into the liquidity on HyperCore. Read precompiles allow smart contracts on the HyperEVM to read L1 state, and the CoreWriter contract allows HyperEVM smart contracts to send actions on HyperCore. This two-way communication between Core and EVM secured by the same HyperBFT consensus protocol unlocks powerful new primitives. Many novel applications have been built on the HyperEVM exploring these possibilities, including LSTs, lending, and vault tokenization protocols. The goal of the Hypurr NFT collection was to share a memento with those who believed in and contributed early on to Hyperliquid’s growth. Each NFT is unique and captures the different moods, hobbies, tastes, and quirks of the Hyperliquid community, as depicted by Hypurr. There are a total of 4,600 NFTs in the collection. 4,313 NFTs went to Genesis Event participants, 144 went to the Hyper Foundation, and 143 went to core contributors, including Hyperliquid Labs, NFT artists, and other contributors. Ownership and use of Hypurr NFTs are subject to the Hypurr NFT Terms and License available here: hyperfoundation.org/nftTerms. Participants who opted in to receive a Hypurr NFT as part of the Genesis Event were screened according to the Foundation's risk-based program. In addition, clustering analysis was conducted to protect against sybil behavior and cap the total number of NFTs received by any given user. Contract address: 0x9125E2d6827a00B0F8330D6ef7BEF07730Bac685. To be clear: No action is required. You do not need to mint. The NFT collection has already been distributed. As always, beware of scams and impersonations.

Hyperliquid will house most of if not all of finance. Stablecoins and related infra would be the backbone of supporting the whole ecosystem. Really excited to be building around this. Mainnet soon!! Hyperliquid

If you’re building a DEX on HyperEVM then you probably know that arbitrage (Hypercore <> HyperEVM) is majority of orderflow. Liquidity depth matters only to the level of supporting median swap sizes with min price impact. Any liquidity beyond essential is additional liability that needs to be incentivised. The name of the game here is efficiency. And for that you need an AMM mechanics to: - Provide minimal slippage to traders (or HL arbers) - Allow LPs to earn same amount of fees with less capital - Protect LPs from principal losses Target is not 100M TVL but to process 100M swap volume with much less TVL. Not everyone will get it. Not everyone will get in. Mantis is almost ready to fly!!

It takes nothing to copy someone else’s work. Execution matters no doubt but working on something new takes a whole lot of effort and is more fulfilling. Ngl but I have been a slow learner and even slower at executing as I didn’t take up the real dev work until recently. Building Mantis from scratch has been the most challenging but best learning experience of my life. Though we haven’t really found pmf till now but I have never given up and will keep trying to build things that push the crypto space forward and solve an actual need rather than copy paste another yield farm. We have been on many chains and each ecosystem gave us fair share of learnings and experience. Now have finally stumbled upon a chain that gives a level playing field to everyone, sometimes the only things a real builder wants. HyperEVM doesn’t need more copy pasta stuff, it needs really innovation solving real need and having right intentions. At Mantis we will try to build the best place to trade crypto especially the correlated assets using Hyperliquid ethos and infra. Here’s a quick brief of what’s coming: - Stableswap: In-house AMM with novel mechanics - Cryptoswap: Hypercore router tapping into orderbook liquidity - Lending: smart collateral unlocking new dimension of capital efficiency - Perps: novel markets using builder codes and HIP-3 Hyperliquid, the house of finance

I don’t know about others but I am serious when I say this: Mantis will provide the simplest experience for LPing. Its because we have made a completely different AMM from scratch for doing this. We got rekt in our early DeFi journey because of 50:50 LPing. So its kinda personal. Mantis brings a paradigm change with Single token deposits and LP token receipt for just one token recording the exact amount you deposited and allowing you to withdraw same amount. As long as you have to provide liquidity in pairs (two tokens) and set price range, no matter what you do its still going to be complex. Hyperliquid

kHYPE coded! Tomorrow $kHYPE, the liquid staked version of $HYPE from @kinetiq_xyz goes live. Users will be able to stake their HYPE for kHYPE to earn native yield on HYPE while enjoying full DeFi composability on HyperEVM (use it as collateral on lending markets or LP/trade on DEXes but by pairing with HYPE) In few days a unique single-sided DEX pool for kHYPE will launch powered by @MantisSwap (imagine a pure kHYPE specific LP token by just depositing kHYPE and earning extra yield from trading fees on Mantis)

Replying to @Slappjakke
If you are looking to farm on HyperEVM let me share one opportunity soon to go live. You LP with single asset in a USD stablecoin omnipool (USDC, USDT0, USDhl, feUSD) or HYPE omnipool (HYPE, LHYPE, mHYPE,..). And since you don’t want to do wash trading, there’s a cool feature that allows you to rebalance the pool in one click. This would be a win-win-win for: - you (earn more fees plus points plus rewards in HYPE), - the traders (get minimal slippage and best execution) - the protocol (more volume and balanced pools) Launching next to next week.

One of the key changes we have made to the design of @MantisSwap is introducing Per-Token Swap Fee (applied on swapped-out/output token) instead of pool-wide fees. Earlier, swap fees used to be defined on the Omnipool level. So say if there are 4 stablecoins in the USD omnipool: USDC, USDT0, HONEY, BYUSD and a base swap fee of 0.01%. Then for every swap between the trading pairs this 0.01% swap fee is charged. But now swap fee can be defined for each token in an omnipool: - 0.01% for USDC (low risk blue chip) - 0.015% for USDTO, - 0.02% for HONEY and - 0.025% for BYUSD (higher risk) This becomes more powerful for Omnipools with liquid staking tokens where different LSTs carry different risks and volatility (imagine this for BERA LST omnipool or HYPE LST omnipool).

Been hearing about number of stablecoin protocols gearing up to launch on HyperEVM in coming weeks/months. For any stablecoin, two things matter the most: - deep liquidity and - strong utility (think collateral in lending, perps etc) @MantisSwap can help with both: bespoke stableswap infra for deep, unified liquidity that supports perps trading liquidity as well. Shoutout to @_brizal for getting me up to speed on the upcoming wave.
