What Hubble Protocol does

Hubble Protocol is a decentralized finance (DeFi) protocol founded in 2021 and built on the Solana blockchain, designed to deliver low-cost lending, borrowing, and structured yield products to retail crypto users. Its core offering is USDH, a censorship-resistant stablecoin native to the protocol, which underpins an integrated product stack including Borrow (collateralized borrowing), Loans (lending markets), Earn (yield generation), a Peg Stability Module (PSM) for stablecoin peg maintenance, and analytics surfaces (Stats, Leaderboard). In September 2022 the protocol announced Kamino Finance as an additional DeFi product to extend USDH utility across the broader Solana DeFi ecosystem.

The protocol operates on a self-serve, product-led growth model: users connect a Solana wallet directly to the web platform without intermediation, and the protocol monetizes via transaction and interest fees on borrowing and protocol mechanics rather than subscriptions. Distribution is community-driven through Discord, Twitter, Telegram, a blog, developer documentation, and a forum. The platform is targeted at global DeFi users and crypto traders who want lower-cost alternatives to Ethereum-based protocols.

Hubble Protocol has raised $15 million in total funding across three rounds (a $3.6M seed in December 2021, a $10M round in January 2022 led by Crypto.com Capital, CMS Holdings and DCG, and a $5M round in September 2022 led by Multicoin Capital). The firm operates as a private venture-backed entity with 1–10 employees. Beyond the September 2022 funding cycle and Kamino Finance announcement, no additional strategic activity is documented in the available source material.

Revenue model

1. Lending/Borrowing Fees: The protocol generates revenue through interest rates applied to borrowing activities. Users pay interest when borrowing against collateral, generating protocol revenue.
2. Protocol Services (PSM, Earn, Loans): Revenue generated from various protocol mechanics including stablecoin operations and yield services.

Core offering

Hubble Protocol is a Solana-based decentralized finance (DeFi) protocol that allows users to borrow against crypto collateral, lend assets, earn yield, and transact with the USDH censorship-resistant stablecoin. The protocol operates self-serve via wallet connection and is anchored by the USDH stablecoin, which supports its lending, borrowing, earning, and peg stability modules.

Product overview

Hubble Protocol is a Solana-based DeFi project offering a censorship-resistant stablecoin (USDH) at its core, supported by a suite of products including borrowing/lending services (Borrow, Loans), yield generation (Earn), a Peg Stability Module (PSM) for stablecoin stability, and platform analytics (Stats, Leaderboard). The products are integrated within a unified platform architecture built on Solana blockchain.

Brands

• USDH: Censorship-resistant stablecoin issued by Hubble Protocol on Solana

Products and services

• USDH Stablecoin Censorship-resistant stablecoin native to Hubble Protocol on Solana, designed to supercharge Solana's liquidity and serve as the foundation for the protocol's DeFi offerings including borrowing, lending, and earning.
• Borrow Borrowing functionality enabling users to access liquidity by using their crypto assets as collateral on the Hubble Protocol lending platform.
• Loans Long-term lending and borrowing service providing decentralized finance functionality with USDH stablecoin as a core component on the Solana blockchain.
• Earn Yield-earning feature allowing users to generate returns on their crypto holdings within the Hubble Protocol ecosystem on Solana.
• PSM (Peg Stability Module) Mechanism designed to maintain the stability of the USDH stablecoin peg by allowing direct swaps between USDH and other stablecoins.

Broad incumbents

• Frax Finance: Hybrid algorithmic/collateralized stablecoin (FRAX) issuer with an integrated lending stack; competes with Hubble's USDH stablecoin and Earn/lending product surface.
• Marinade Finance: Leading Solana liquid staking protocol; competes for the same Solana-native DeFi user mindshare and treasury allocations that Hubble targets with USDH-based yield products.
• Aave: Largest decentralized lending protocol; offers the same core lending/borrowing primitives as Hubble across multiple chains and is the cross-chain benchmark product Hubble's cost advantage is positioned against.
• Compound: Pioneer Ethereum-based money market protocol; offers decentralized lending/borrowing as a core service analogous to Hubble's Borrow/Loans, though on a different chain.
• MakerDAO / Sky: Decentralized stablecoin issuer (DAI/USDS); directly competitive with Hubble's USDH as a censorship-resistant, crypto-native dollar stablecoin, though with a much larger scale.

Direct peers

• Kamino Finance: Solana-native DeFi protocol for lending, borrowing, and liquidity management. Direct overlap with Hubble's Borrow/Loans/Earn surface, and was explicitly referenced as a Hubble-adjacent product within the Hubble ecosystem (Sept 2022).
• MarginFi: Solana-based lending and borrowing protocol competing directly with Hubble's Borrow/Loans for the same collateralized borrowing market on Solana.
• Solend: One of the earliest and largest Solana lending markets, offering deposit and borrow functionality that overlaps directly with Hubble's lending/borrowing products.
• Drift Protocol: Solana DeFi protocol combining a perpetual DEX with lending and yield features; competes with Hubble for the same Solana DeFi user wallet.

Emerging players

• Jupiter: Solana's dominant DEX aggregator, which has been expanding into lending and perps. As the central liquidity and distribution layer on Solana, it is the upstream funnel that Hubble's PLG distribution depends on.
