Since the launch of Yield Basis, all pools have been fully filled:

• With each raise, the cap was filled in a matter of minutes

• Demand for IL-free yield far exceeds the TVL that Yield Basis can accept

• Thus, the primary focus is safe TVL scaling

By capping YB pools, Yield Basis limits its influence on the $crvUSD peg and ensures safe utilization of Curve’s infrastructure:

• IL is mitigated by creating and maintaining 2x leverage in YB pools.

• $crvUSD borrowed from Curve DAO is used for liquidity and leverage purposes.

• Swaps in YB pools trigger $crvUSD-stable swaps at Curve; significant BTC or ETH volatility could influence the $crvUSD peg

The YB<>$crvUSD interaction was recently covered in a comprehensive analysis by Llamarisk. It emphasizes the necessity of growing $crvUSD supply (minted by independent users) among other recommendations.

The observation on the possible limit for Yield Basis TVL cap calculated based on the current state of PegKeepers pools now is approximately $25m lower than the actual TVL.

These results clearly demonstrate the following: Yield Basis requires a solution to provide additional support for the $crvUSD peg beyond the current subsidies (YB emissions provided as bribes to $crvUSD pools).

$crvUSD Hybrid Vault

Hybrid Vault is a vault that directly links $crvUSD peg support action with controlled TVL onboarding into the Yield Basis pool.

The core idea is to enable users to enter the Yield Basis pool by establishing a Personal Cap, determined by their contribution to $crvUSD peg stability:

$crvUSD deposit & stability contribution

• Users deposit $crvUSD into the Hybrid Vault.

• Deposited $crvUSD is automatically staked into $scrvUSD, generating yield (currently approximately 2.5% APY).

Personal Cap Creation

• Upon deposit, a Personal Cap is created automatically.

• The Personal Cap equals 2.5 × the deposited $crvUSD amount.

• This cap defines the maximum amount of capital the user can onboard into the Yield Basis pool outside of the usual caps.

Withdrawal mechanics

• Withdrawal of $crvUSD from the Hybrid Vault is gated by withdrawals from the Yield Basis pool.

• To withdraw X amount of $crvUSD, the user must first withdraw 2.5*X worth of assets from the Yield Basis pool, provided that there was no free cap beforehand.

• Asset values are calculated at the exchange rate at the time of withdrawal.

Example user journey:

• The user deposits 1,000 $crvUSD into the Hybrid Vault (which is deposited into $scrvUSD thereafter)

• The user deposits $2,500 worth of WETH into the WETH pool.

• To withdraw 50% of the $crvUSD position (500 $crvUSD), the user must first withdraw $1250 equivalent to the existing WETH position, calculated at the prevailing exchange rate at the time of withdrawal.

The llamarisk report primarily emphasizes the need for additional mint markets to preserve $crvUSD stability:

“This is because mint markets remain the most direct revenue driver for crvUSD (creating demand for the stablecoin via scrvUSD).”

The Hybrid Vault serves a very similar purpose:

• It creates direct demand for the stablecoin, as participation requires $crvUSD deposits (which must be directly minted or purchased by the user).

• It can be considered as an alternative revenue driver for $crvUSD, since TVL deposited in case of a Personal Cap generates revenue for $crvUSD (which is tied to $crvUSD ownership & usage).

Explanation of $crvUSD alternative revenue driver: user deposits 1,000 $crvUSD and $2,500 WETH to the Vault.

The user's annual yield is a theoretical calculation that assumes the $scrvUSD Vault reward APY and the WETH price remain stable and that the WETH earns an 8% APY, as in the simulations:

• $25 from $scrvUSD and 8%, or $200, from WETH

• If the user deposits $1,000 in $crvUSD into a low-risk, stablecoin yield option, such as the $crvUSD-$USDC pool at StakeDAO, the revenue will be ~7%, or $70. The $ETH LST revenue will be ~2.5%, or $62.5. This gives us a total of $132.5.

• Therefore, by owning $crvUSD and utilizing the unique option to participate in the Yield Basis Pool via the Hybrid Vault, the user generated an additional $92.5 in yield.

So, Hybrid Vault replicates the core economic mechanics of the mint market, incentivizing $crvUSD demand through a revenue-generating mechanism.

The Llamarisk analysis further states:

“Additional mint markets: In addition, we believe there is a need for additional mint markets. This enables use cases where leverage is, ideally, independent of market cycles to avoid contraction in bearish conditions and attract size.”

The introduction of the Hybrid Vault directly aligns with it, as it:

• Enables demand mechanism that is less dependent on market cycles

• Provide alternative, non-cyclical pathway for scale $crvUSD

It becomes possible since Yield Basis pools generate yield from volatility, not from market direction itself.

So, the Hybrid Vault is not only a solution to scale Yield Basis, it can be also considered as a solution to enrich $crvUSD yield options.

The Hybrid Vault design was initiated earlier, and its code is currently under audit.

After the audit is completed, the following steps will be taken:

First, creating the official YB DAO proposal containing the specifications and initial cap to start using the Hybrid Vault

• After governance approval, it will be implemented

• Hybrid Vault deposits & UI will be enabled right after proposal passes

Note that:

• YB DAO decides on Hybrid Vault Cap for each pool, since the protocol still has an overall TVL cap, as it is limited primarily by the $crvUSD credit line from CurveDAO.

• The vision is to gradually increase the utilization of the credit line by Hybrid Vault until the $1 billion limit is reached.

After reviewing the results of the Hybrid Vault implementation and its impact on the $crvUSD peg stability, YB DAO will make decisions regarding the next steps for the $crvUSD credit line.
