Fragmetric

Fragmetric is a liquid restaking protocol built natively on Solana. Users can restake assets like SOL and JTO. This lets them earn different yield streams. They also keep their liquidity. The platform uses Liquid Restaking Tokens (LRTs) like fragSOL and fragJTO. This lets users earn rewards from staking, MEV, and restaking activities. The idea is simple: why lock up your tokens when you can stake, earn, and still take part in DeFi?

Fragmetric offers a liquid restaking token (LRT) instead of locking your assets. For example, you get fragSOL for SOL or fragJTO for JTO. You can trade these tokens, use them in DeFi, or move them freely. They also earn staking and MEV-based rewards in the background.

The protocol centers on a unique standard, FRAG‑22. This standard allows for transfer hooks and real-time yield accounting. Now, you won't wait for rewards to build up or stress over wrong splits. The protocol automatically figures out ownership and yield every time tokens move.

How Does Fragmetric Work?

Fragmetric integrates with the Solana ecosystem through token extensions and validator staking.

1. Deposit Assets

Users deposit SOL or JTO into Fragmetric’s staking vaults.

2. Receive fragTokens

In return, users get fragSOL or fragJTO. These liquid tokens represent a staked position.

3. Protocol Restakes for You

Fragmetric delegates your assets to top validators and restaking methods. This generates extra MEV and yield layers.

4. Transfer Hooks Trigger Updates

When you move your fragTokens, the FRAG‑22 standard triggers a smart contract hook. It recalculates your rewards and yield pool share in real time.

5. Earn Continuously

You earn yield from staking, MEV, and restaking bonuses while using your fragTokens in DeFi.

This system solves common issues in restaking protocols. With Fragmetric, everything is modular and real-time.

Fragmetric’s Core Features

What makes Fragmetric unique among restaking projects?

1. FRAG‑22 Token Standard

The FRAG‑22 standard adds smart transfer hooks to SPL tokens. This allows immediate yield recalculation and distribution as tokens move across wallets or DeFi apps.

2. Liquid Restaking Tokens (fragSOL, fragJTO)

FragTokens are tradable and usable in DeFi. They still earn staking and MEV rewards.

- Real-Time Normalized Rewards

Unlike other LRTs that earn rewards passively, Fragmetric ensures up-to-date accounting of yield for each holder.

3. Multi-Asset Support

Fragmetric starts with SOL and JTO, but plans to add BTC (via Kamino), ETH (via bridges), and others.

4. Developer SDK and Composability

Fragmetric’s SDK lets any DeFi project integrate fragTokens and create custom strategies, vaults, or rewards.

Fragmetric vs Competitors

In the (LRT) space on Solana, not all platforms are equal. Many focus only on issuing liquid staking tokens. Fragmetric builds a complete restaking infrastructure, with real-time accounting, programmable token hooks, multi-asset support, and developer tools.

Here’s how Fragmetric compares to competitors like Jito, Renzo, and Kyros/Adrastea across five key areas:

1. LRT Support

All major protocols offer an LRT product. However, only Fragmetric supports multiple tokens from the start, including fragSOL and fragJTO. Its design easily adapts to new assets like BTC or ETH.

Fragmetric: fragSOL, fragJTO, future support planned

Jito: jitoSOL only Renzo: ezETH only Kyros/Adrastea: kSOL, aSOL

2. Real-Time Accounting

Many protocols, including Jito and Renzo, use batch-based accounting. They update rewards periodically.

In contrast, Fragmetric uses the FRAG‑22 token standard and its Normalized Token Program. This allows real-time reward calculations at the moment of transfer.

This keeps rewards accurate and current. It also allows for dynamic uses, like composable vaults and automated DeFi strategies.

3. Multi-Asset Support

Fragmetric is built for multi-asset restaking. It currently supports SOL and JTO and plans to add BTC (via Kamino), ETH, and more, making it highly flexible.

4. Developer SDK

Fragmetric is not just for users; it’s also for builders. It offers a plug-and-play SDK. This helps developers add fragTokens to their DeFi apps, strategies, and automation tools.

This level of developer composability is currently unique among LRT protocols on Solana.

5. Token Hooks

Fragmetric’s token hook architecture, enabled by FRAG‑22, is a major innovation. These smart hooks automatically trigger events during transfers. They handle things like reward recalculations and compliance checks. No other protocol, including Jito, Renzo, or Kyros, currently offers this event-driven token behavior. Fragmetric currently covers five main areas: real-time accounting, multi-asset staking, developer SDKs, token hooks, and composability.

Fragmetric stands out by combining several features. It uses multi-asset restaking, an event-driven setup, and real-time reward distribution. Other protocols mainly focus on issuing one LRT token. This makes Fragmetric a foundational layer for modular, programmable DeFi on Solana.
