The novel price-pegging mechanism underpinning crvUSD, the month-old stablecoin from Curve Finance, is proving highly effective so far.

On Monday, Curve shared data showing that its stablecoin has traded within a less than 0.5% price range since launching.

Looking at the performance of rival decentralized stablecoins during their first month for comparison, DAI fluctuated within an 8% range, FRAX oscillated by 10%, and sUSD bounced around by 2%, according to CoinGecko.

Users have already minted 4.7M crvUSD, according to Dune Analytics. Based on data from CoinGecko, a market cap of $4.7M crvUSD would rank the project as the 42nd-largest stablecoin protocol.

Curve is the fourth-largest DeFi protocol with a total value locked of $4.3B across 12 chains, according to DeFi Llama. Its native CRV token is down 3% in the past week.

Bear Market Disrupts Stablecoin Sector

crvUSD’s growth comes as many developers see opportunities in the stablecoin sector.

Centralized stablecoins were disrupted by regulations and exposure to the legacy financial sector in recent months. In February, New York financial regulators ordered Paxos to stop issuing new BUSD tokens. One month later, USDC, the second-largest stablecoin, briefly depegged as holders feared the exposure of USDC’s issuer to failed U.S. banks could pose a threat to its collateral reserves.

Confidence in incumbent decentralized stablecoins took a hit after the collapse of the Terra network and its algorithmic UST stable token last year. Then, MakerDAO’s DAI stablecoin lost its peg alongside USDC in March due to more than 40% of its collateral assets comprising USDC at the time. Further, Maker’s founder recently expressed an interest in freely floating DAI against the dollar in the future.

The turmoil in the stablecoin markets created strong demand for stablecoins offering resilience to price volatility and regulatory interference, such as decentralized and overcollateralized tokens.

Peg Keepers

Curve deployed its stablecoin on the Ethereum mainnet nearly four weeks ago, inspiring degens to ape $2M into the protocol despite it lacking a user interface (UI) at the time. Curve launched a UI for crvUSD on May 17.

crvUSD currently can only be minted against sfrxETH, the liquid staking derivative (LSD) from Frax Finance, and is backed by $6.4M worth of sfrxETH. Curve said it will onboard additional LSD tokens, and is consulting with its community on whether it should explore support for ETH and WBTC.

With users continuing to earn staking rewards on their collateral when minting crvUSD, users are reporting earnings of close to 3% after paying interest on the stablecoins.

crvUSD uses “stability pools” and PegKeepers” to maintain its price at $1. Stability Pools are liquidity pools that pair crvUSD with other stablecoins — USDC, USDT, USDP, and TUSD. PegKeepers are smart contracts assigned to a particular Stability Pool which can mint a limited number of crvUSD to push the token’s price towards $1.

When the price of crvUSD exceeds $1 in a specific Stability Pool, the PegKeeper can mint crvUSD and deposit it to the pool to place downward pressure on its price. Transversely, PegKeepers can remove and burn their crvUSD liquidity when the token’s price is below $1, reducing supply and theoretically pushing prices up.

Steep interest rates are also imposed on crvUSD borrowers when its price slides below $1 to incentivize users to purchase crvUSD to pay down their debts. Rates also fall when crvUSD is above $1 to encourage loan generation.

Curve said just 14% of crvUSD’s supply is backed by PegKeepers, while its Stability Pools hold 2.5M crvUSD each.

LLAMA Liquidations

crvUSD introduced a unique liquidation mechanism called the lending-liquidating AMM algorithm, or LLAMMA, in a bid to reduce the effects of liquidations on borrowers.

When the value of the collateral assets backing a user’s crvUSD approaches its liquidation price, the protocol will gradually convert the collateral into stablecoins rather than unwind the entire position in a single trade. Then, as the price of collateral rises, Curve converts the stablecoin collateral back to volatile assets.

However, this process comes at a small cost to users’ collateral.

Curve currently receives price data from Chainlink’s oracles, but Curve has hinted it will provide the infrastructure itself in the future.
