Why Use Hubble?

Instead of just holding your tokens in a wallet, you can make them work for you.

Keep upside to your collateral while earning yield elsewhere

Take a loan in USDH and use it across Solana to earn yield. Once you are done with that position, you can return to Hubble and pay back your debt. At the end of the process you have your collateral back and the profit from deploying your stablecoins in DeFi. If your collateral has increased in price, you have benefitted from that price action as well.

Earn yield on collateral

Hubble accepts a variety of yield-bearing collateral assets, such as mSOL, stSOL and daoSOL, with more assets being actively onboarded. These assets can be deposited in Hubble to mint USDH, and will retain exposure to the staking APY.

In the future, users will have the ability to allocate their collateral assets to various yield strategies, which will utilize their assets in one of Hubble's partner protocols.

Get leveraged

Hubble has various LTV (loan-to-value) ratios across different vaults and assets. This ranges from 97% for kTokens, to 80% or lower for volatile assets. These LTVs allow you to leverage your assets according to your risk appetite. Note that we recommend caution when leveraging your positions.

Earn from democratized liquidations

Deposit USDH into Hubble's USDH Vault (formerly Stability Pool) and help keep the platform healthy by guaranteeing loans are repaid. As a reward, USDH Vault providers earn a net positive ~10% difference from liquidated accounts.

The USDH Vault liquidation model works in combination with market-based liquidations to ensure protocol solvency.

Security

Hubble exercises extreme caution in its development process. No single line of code is deployed if it has not been subject to our testing process. Hubble does not buy into the "move fast and break things" ethos. Typically, robust updates and features are delayed until they have gone through an independent security audit. Thus far, Hubble's code base has undergone 5 security audits.

USDH Peg Stability

Since Hubble's launch in January 2022, the USDH peg has been remarkably stable despite turbulent market conditions. USDH now maintains its peg primarily via Hubble's Peg Stability Module (PSM), a peg-stabilizing mechanism initially introduced by MakerDAO.

The PSM allows for zero-slippage swaps between USDH and USDC, enabling frictionless below and above-peg arbitrage. Alongside the PSM, Hubble can use Stability Fees and the Hubble Native Yield (HNY) to impact USDH demand and thus USDH peg.
