Hubra

Hubra is a Solana staking platform built on top of a validator that has maintained continuous uptime since 2020. The project formally launched in 2021 under the name SolanaHub, initially positioning itself as a broad DeFi aggregator on Solana. Over subsequent years it underwent a deliberate strategic pivot, narrowing its scope to become a dedicated staking surface for long-horizon SOL capital. By 2025 the platform recorded a 9x increase in TVL under the new focus.

The core proposition is self-custody. When users delegate SOL to Hubra's validator, the stake account stays in their wallet at all times — Hubra never takes possession of funds. The validator's vote account is 7K8DVxtNJGnMtUY1CQJT5jcs8sFGSZTDiG7kowvFpECh and its six-year track record of uninterrupted participation in Solana consensus is the platform's primary trust signal. Notable delegators listed on the website include the Solana Foundation, DoubleZero, and The Vault.

Products

Native SOL Staking is a direct delegation to Hubra's validator with no smart contract layer. Users receive epoch-native rewards that accrue directly from Solana's inflationary issuance, calculated as (user active stake / total active stake) multiplied by (epoch issuance) multiplied by (1 minus validator commission). Deactivation follows Solana's standard epoch-boundary cooldown, and Hubra explains the underlying mechanics in detail on a dedicated staking-mechanics page.

Liquid Staking (raSOL) mints raSOL tokens against staked SOL. The token is composable across Solana DeFi — usable as collateral or yield-bearing inventory while the underlying position continues to earn staking rewards. As of mid-July 2026 the exchange rate sits at approximately 1 raSOL = 1.0142 SOL, reflecting accumulated staking yield. The raSOL mint address is HUBsveNpjo5pWqNkH57QzxjQASdTVXcSK7bVKTSZtcSX. Phantom data as of July 17, 2026 shows 7,357 raSOL in circulation across 6,706 holders, with a market cap of approximately $644,000 and $685,000 in liquidity.

Instant Unstake provides a single-transaction exit from either a native or liquid staking position, subject to a price-impact fee to cover the liquidity cost.

USDC Earn (raUSDC) applies automated on-chain yield strategies to USDC deposits via audited venues. The raUSDC mint address is 53fZaJGDMHcfku8pzZak5obVFUUjVxwqRTF63M3SQiSS.

raSOL Max is a managed leveraged staking product introduced in 2026. Rather than requiring users to manually loop LST and SOL borrow positions, Hubra constructs and manages the leveraged position end-to-end. The strategy has consistently delivered approximately 10% APY while the broader looping market generated negative APY as of mid-July 2026. Since the product's launch announcement, Hubra reported over 100 new holders and a 2x increase in raSOL Max TVL within the first monitoring period.

Technical Architecture

Hubra operates two functionally identical surfaces for the same on-chain operations: a consumer web application at hubra.app and an unauthenticated HTTP API that returns unsigned transactions for local signing. Both interfaces invoke the same server logic, producing identical on-chain outcomes regardless of whether a user is connecting a wallet through the UI or integrating programmatically. This dual-surface architecture positions Hubra to support agent-driven or automated treasury management workflows without a separate integration layer.

The platform sponsors gas fees for all operations, meaning users can begin staking without holding SOL to cover transaction fees, lowering the onboarding barrier for first-time Solana participants.

Fees

As of July 14, 2026, Hubra dropped its LST protocol fees to 0%. The Sanctum Reserve Pool Fee of 2.5% remains in effect as a standard infrastructure charge on the liquid staking layer but is not a Hubra-controlled fee.

Ecosystem Integration and Reach

The platform reports 6,500 stakers, 162,930 SOL in TVL, a projected approximately 6.01% APY on native staking, and more than 10 DeFi partners integrated with raSOL. In February 2026 Hubra announced a partnership with Pye to work on programmable staking markets. The platform added full localization in seven new languages in July 2026 to serve its growing international user base.

Hubra publishes a blog under the name Hubra Journal, covering Solana staking mechanics, DeFi strategy, and protocol governance changes. Recent articles address Solana's Alpenglow consensus transition (BLS keys going live on mainnet as of July 2026), the implications of SIMD-0550's proposed changes to staking yield, and comparative analyses of major Solana LSTs including JitoSOL, mSOL, and INF.

Market Context

Hubra competes within the Solana liquid staking sector, which as of late 2025 held approximately 60.5 million SOL across all LST protocols, representing around 13.76% of all staked Solana. Hubra's differentiation rests on the age and continuity of its underlying validator, its self-custodial design, the managed leverage offering via raSOL Max, and its dual API/UI access model.
