Restaking dominated Ethereum DeFi for two years. EigenLayer pulled in tens of billions, and the broader thesis — restake your security-providing assets to earn yield from additional protocols — became one of the dominant DeFi primitives of the cycle.
Solana didn't have a direct equivalent. SOL staking was straightforward delegation to validators. There was no general restaking layer where you could double-deploy your staked SOL to secure additional services.
Solayer fixed that, then went further. As of mid-2026 Solayer runs a restaking protocol (sSOL), a yield-bearing stablecoin (sUSD), and a hardware-accelerated SVM L1 chain (InfiniSVM) that targets 330,000 TPS. The product surface is broader than any single Ethereum-side restaking protocol, and the bet is more ambitious.
This post explains what each piece does, the actual mechanics, and the open questions.
sSOL: the restaking primitive
Solayer's core product is sSOL, the restaked-SOL liquid staking token. The flow:
- Deposit SOL → mint sSOL (1:1 at deposit time, accruing yield over time)
- sSOL is delegated through Solayer to a validator set that secures additional services (oracle bridges, sequencers, off-chain compute)
- Solayer aggregates the additional services' yield and distributes it pro-rata to sSOL holders
- Total yield = base SOL staking yield + restaking yield from secured services
The "secured services" are the interesting part. EigenLayer's Ethereum version pioneered the model — restaked ETH secures "actively validated services" (AVSs) that pay yield in their own tokens. Solayer is using the same primitive on Solana, with services that include:
- Oracle bridge attestation — restakers help attest to cross-chain oracle data
- Sequencer security — restakers back the sequencer set of certain rollups
- Bridge endpoint validators — restakers vouch for bridge state across chains
- InfiniSVM economic security — Solayer's own L1 uses restaked SOL as part of its security stack
Each service pays Solayer a fee, which becomes yield for sSOL holders. As of mid-May 2026, the blended yield on sSOL is roughly 7.5-9% APY — above plain SOL staking (~6.5%) but below high-risk DeFi yields.
The risk profile is also above plain staking: you inherit the slashing exposure of every service your restake is securing. If a service slashes for misbehavior, sSOL holders bear a proportional loss. Solayer has been conservative about which services it admits, but this is the structural tradeoff.
sUSD: yield-bearing dollars
The second piece is sUSD — Solayer's dollar token, pegged 1:1 to USD and backed by short-dated US Treasuries.
Reserve composition:
| Backing | Mechanism |
|---|
| US Treasuries | Held via licensed custody partners |
| Cash buffer | For instant mint/redeem |
Yield is roughly 4-5% APY, tracking Treasury bill rates. The yield accrues to holders by default — sUSD is a yield-bearing token, not a wrapper that requires an explicit deposit step. Hold sUSD in your wallet, the balance ticks up.
This is structurally similar to Jupiter's recently-launched JupUSD (BUIDL-backed) and to other T-bill stablecoins like USDS. The differentiators for sUSD are: native Solayer integration (use it as collateral in InfiniSVM apps, restake it for additional yield), and proven track record (sUSD has been operational since mid-2025 versus JupUSD's May 2026 launch). Jupiter's broader token program also winds down this year — we cover the details in our breakdown of the final Jupuary 2026 JUP airdrop.
sUSD's TVL is around $150M+ as of mid-2026 — material but smaller than USDC's $10B+ on Solana. The growth path is whether DeFi protocols treat sUSD as a primary dollar token or as a niche alternative to USDC. For the closest competing design, our explainer on JupUSD, Jupiter's BlackRock BUIDL-backed yield-bearing stablecoin breaks down how its reserves differ from sUSD's.
InfiniSVM: the bet that matters
The third piece is the most ambitious. InfiniSVM is a Solana Virtual Machine implementation running on dedicated hardware — InfiniBand RDMA networking, custom NICs, optimized validator nodes. It went live as an Alpha Mainnet in January 2026 with throughput above 330,000 TPS and roughly 400ms finality.
For context:
- Solana mainnet: ~3,000 TPS sustained, sometimes more under bursts
- Ethereum L1: ~15 TPS
- Most Solana L2s and parallel chains: target 10k-50k TPS
InfiniSVM at 330k TPS is genuinely fast. Whether anyone needs that for current DeFi workloads is a separate question. Solayer's three-layer bet is one of the more ambitious moves in a fast-moving ecosystem — our Solana ecosystem overview for 2026 places restaking and high-throughput SVMs in the wider landscape. The bet is that high-frequency trading, real-time gaming, and AI agent transaction loads will outgrow standard Solana mainnet's throughput, and InfiniSVM positions Solayer as the obvious migration path.
Economically, InfiniSVM uses Solayer's restaked sSOL as part of its security stack. Apps deployed on InfiniSVM benefit from Solayer's institutional sSOL TVL backing the chain, which is meant to reduce the chicken-and-egg problem most new chains face.
The technical risk is real: InfiniBand-based networking is unusual in blockchain infrastructure, and the validator set requires specific hardware that's harder to decentralize than a standard Solana validator. If you're an InfiniSVM operator you need RDMA NICs, specific switch hardware, and tight latency to the rest of the validator set. This trades decentralization for throughput.
The adoption risk is real too: a hardware-accelerated SVM chain is only valuable if dApps deploy there. Solayer launched a $35 million ecosystem fund in January 2026 to subsidize early apps. Whether that bootstrap takes is the open question for the next 12 months. Early Solayer activity is also a candidate for future points programs — if you farm these, our directory of Solana airdrop tools and trackers helps you monitor eligibility and farming progress.
