The latest salvo in the multibillion-dollar “Curve Wars” might be the most daring yet, and the protocol’s response has revealed deep ideological fissures within the decentralized finance (DeFi) group.
Curve.Finance is presently the most important DeFi protocol with $20.8 billion in complete worth locked (TVL) per CoinGecko. The protocol holds a significant place within the DeFi ecosystem as a consequence of its CRV token rewards emissions – a key supply of earnings for a number of different protocols and one of many foundational pillars of a rapidly-growing $270 billion ecosystem.
On Wednesday night time a younger mission – memecoin-flavored Mochi Inu – executed a collection of transactions that tilted CRV rewards in its favor by utilizing a token-locking mechanism in Convex Finance, a yield farming protocol constructed on high of Curve.
This jockeying for CRV emission rewards is frequent observe amongst protocols, and sometimes called the “Curve Wars.”

In a Twitter thread Wednesday morning, Mochi formally introduced themselves as a brand new participant within the Curve Wars, writing that “Curve is the backbone of DeFi, and Convex is the kingmaker of Curve.”

Shortly after, nevertheless, the Curve Emergency DAO, a nine-person group utilizing a multisignature scheme with restricted governance powers over CRV reward emissions, reduce off Mochi’s rewards, and in a governance discussion board submit, semi-anonymous Curve contributor “Charlie” wrote that Mochi’s in a single day rise was a “clear governance attack.”
In an interview with CoinDesk semi-anonymous Mochi founder AZ, additionally sometimes called Azeem, stated that the Emergency DAO’s safety issues had been “reasonable” and that he hopes to deal with them within the coming weeks.
Nonetheless, the choice from the DAO has prompted important group debate, as some have argued that the protocol mustn’t single out anybody consumer and that blacklisting one other protocol runs towards DeFi’s open, permissionless ethos.
In an interview with CoinDesk, Charlie stated that the choice to chop off Mochi’s CRV rewards wasn’t made evenly, however that the state of affairs was distinctive.
“I hate this ‘I need protection’ meme we’ve seen from Gensler,” he stated, referring to SEC Chairman Gary Gensler. “Curve definitely doesn’t want to be gatekeepers or protectors but we gotta draw the line somewhere when it comes to bad behaviour. Mochi crossed it 7 times over last night.”
Exploitative or exploit?
Regardless of whether or not Mochi’s maneuvering was an assault or a intelligent abuse of assorted DeFi protocols’ features, the occasions Tuesday night time are a exceptional show of the interconnected nature of the DeFi ecosystem, spanning a number of protocols and features.
Curve is a decentralized change device primarily designed for swapping like-assets, equivalent to totally different stablecoins or ETH and its staked derivatives equivalent to stETH. Curve’s liquidity suppliers are rewarded with CRV, the protocol’s governance token.
At the core of Mochi’s “governance attack” is veCRV – voting escrow Curve, a locked model of CRV that grants holders the power to vote on “boosting” CRV rewards to sure liquidity swimming pools. Throughout 2021, numerous protocols have vied to build up CRV and lock it as veCRV with a purpose to enhance rewards to swimming pools that may profit them. As a consequence, locked Curve is a well-liked metric to trace:
#TheLockening🔒Nov. 2-7, 2021
Convex veCRV: 136.58m ( ⬆️🔒2.83m)
608k $CRV 🔄 veCRV right now (41.85% of each day emissions)
91.31% of circulating CRV🔒as veCRV
Convex vote-locked CVX: 19.9m (⬆️🔒1.1m)

Mochi, a platform just like asset-backed stablecoin issuers Spell and MakerDAO, closely incentivized deposits to a Curve pool that included USDC, USDT, DAI and Mochi’s native stablecoin USDM main into Tuesday night time’s occasions, finally attracting over 170.2 million in liquidity at its peak, per Azeem.
Another key cog within the occasions is Convex Finance. Convex is a protocol designed to maximise CRV rewards, and the protocol is presently the most important veCRV holder with 136.58m tokens – over a 3rd of CRV’s circulating provide. Users who lock Convex’s CVX token have the appropriate to vote proportionally on how the protocol’s tokens are used for enhancing emissions.
On Tuesday night time, the entire above protocols and mechanics had been on show. A Mochi group member swapped $46 million in USDM for DAI utilizing the Mochi Curve pool, swapped the DAI for ETH, and used a big portion of that ETH to buy massive portions of CVX, which they then locked.
This would have allowed them to vote on extra CRV rewards for the Mochi pool, which in flip would have attracted extra liquidity, permitting them to swap much more USDM for stablecoins to purchase extra CVX – finally making a flywheel closely tilting CRV rewards of their favor and attracting large sums of liquidity to their platform.
It's loopy to me that this mochi / musd factor might work (so long as cvx is up solely)…
Now they’ve thousands and thousands in convex votes to direct liquidity to the musd pool
Which means insane yields for LPs there
Which means they’ll mint extra musd for stables to purchase extra cvx

Multiple observers have famous that KEEP, FRAX, OHM, CREAM and different DAO communities are voting or have voted to pursue comparable methods (if at a smaller scale), however the calls for of public governance have slowed them down, and so they couldn’t unilaterally transfer to grab voting energy as Mochi did on Tuesday night time.
As Mochi’s transactions unfolded, DeFi group members had been fast to level out that the younger protocol had quite a few safety and operational flaws, together with that the group might arbitrarily print extra USDM and that the worth oracle for the token – a key piece of infrastructure that’s typically the goal of hackers – was manually set by a group member’s deal with.
Dug across the mochi contracts and it's comedy gold
– Price oracle for $mochi is actually only a quantity set by a scorching pockets (who wants chainlink lmao)
– The mochi token is upgradeable by a 1-of-3 multisig ("multisig") with no timelock
– The identical multisig owns 99.5% of all mochi

Additionally, Azeem is a controversial determine within the DeFi area. While working the Armor.fi insurance coverage protocol, the developer was accused of personally deciding to not pay a consumer with a legit declare in February. Later within the month, following a social engineering assault on an Armor group member that resulted in a $1 million loss, Azeem defended his colleague by saying that the developer was “sleepy and tired,” a phrase which has turn into extensively mocked.
Multiple high-profile DeFi builders criticized the scheme, with Yearn.Finance founder Andre Cronje referring to the transactions as “amazingly scammy.”
This is amazingly scammy;
1. Be Mochi
2. Incentivize USDM/3pool
3. Get $100mm liquidity
4. Mint free Mochi
5. Use Mochi to mint 46mm USDM
6. Swap USDM to DAI
7. Buy 46mm price of CVX
8. Use CVX to vote extra incentives
9. Liquidity will increase extra
10. Repeat advert infinitum https://t.co/SU1NwKDOmm

In an interview with CoinDesk, pseudonymous Yearn core contributor and one of many 9 members of the Curve Emergency DAO, Banteg, stated the flywheel was harmful given USDM’s doubtful backing.
“Internal thinking was around mitigating the feedback loop Andre described when he first drew attention to the issue. With high concentration of votes towards one pool, it could cut into other pools, ultimately hurting Curve [liquidity providers],” Banteg stated. “We know for a fact USDM is a worthless collateral. In retrospect, Curve DAO should’ve done a better due diligence on it.”
The Emergency DAO finally elected to chop off the Mochi pool’s rewards early Wednesday morning. At the time of writing, the pool has over 31 million USDM valued at $.49 cents per token and $1.3 million in stablecoins. Banteg famous he was not among the many signers on the transaction that ended emissions to Mochi’s pool.
Charlie stated that the shortage of fundamental safety practices and never Azeem’s repute led the DAO to take unprecedented motion. This is the primary time the Emergency DAO has been invoked.
“I don’t think this Mochi situation is comparable to any other protocol building around Curve. There is a clear pattern of misbehaviour and lack of concern for security, best practices and users’ funds.”
“I’m aware [Azeem] hasn’t got the best reputation but I also don’t know about what happened with those other projects and I prefer to work with the information I do have.”
Good query. Emergency DAO is a committee which is supposed to behave quick in emergencies. Decisions of emergency DAO could be reverted by the primary DAO. Besides, the emergency DAO is appointed by the primary DAO and presently has no group members.https://t.co/5UNUOTUxwX https://t.co/cJvczYhSoC

Azeem informed CoinDesk that Mochi will deal with the safety issues expressed by the Emergency DAO, and that the group plans so as to add “more secure multisig structure with additional signer requirements per transaction, suitable LTV parameters and clear tokenomics.”
“Once these are resolved we believe the gauge reinstatement will be deemed suitable, independent of strategic fears the whales and influencers may have with respect to our bold approach to gaining voting power in the DAO,” he stated.
Rules of engagement
Mochi’s aggressive technique and Curve’s ensuing governance motion has prompted important debate within the DeFi group.
Azeem blamed an unnamed “DeFi Cartel” for a way Mochi Inu has been handled, saying that Mochi poses a risk to the Curve Wars establishment.
“They are shocked and feel threatened that a small player on the outskirts of the Curve/Convex ecosystem became a powerhouse and a threat to their fledgling monopolies overnight. Is this not DeFi?” He requested.
Likewise, quite a few observers have criticized each the existence of the Emergency DAO and that they selected to behave, saying that signaling out a single consumer is inappropriate in what ought to be a permissionless system.
Mochi finance fiasco is sort of fascinating.
Mochi created a really harmful market circumstances for its customers, nevertheless it didn't break any Curve guidelines.
Curve's Emergency DAO's actions might need been unjustified. The intentions had been proper, however was it their place to interject?

Regardless of the controversy, Curve’s Charlie expressed some aid that there at the moment are clear guidelines of engagement within the Curve Wars.
“I’m somewhat glad we drew the line of what a protocol can and can’t do. We’ve seen an escalation of bribes with different protocols trying to grab more and more power with Convex and Curve.”
