Islamic Finance Principles Assessment
Riba — Does Solayer involve interest?
Solayer's core restaking mechanism draws rewards from Solana staking and AVS yield, which is broadly performance-based and permissible in structure. However, the protocol also builds sUSD, a stablecoin explicitly backed by US Treasury-bill interest, which is a direct riba exposure within the ecosystem. Muslim investors should treat the T-bill-backed component as a clear caution flag even while the restaking layer itself is more defensible.
Assessment: Riba Dominant
Score: 38.5/100
Our methodology examines 10 criteria to evaluate how well Solayer avoids interest-based mechanisms.
Solayer's revenue derives from two distinct sources: restaking/AVS fees generated by delegating sSOL to Actively Validated Services, and interest income from US Treasury bills backing the sUSD stablecoin. The first is a service-fee model tied to actual network activity and is not inherently interest-based. The second is unambiguous riba — T-bill yield is fixed-rate government debt interest, and building a product line around harvesting and distributing that yield to users (via sUSD and the Emerald Card) introduces conventional interest income directly into the protocol's financial architecture.
The base staking flow — depositing SOL/LSTs for sSOL, then delegating to AVS — pays rewards drawn from Solana's proof-of-stake issuance plus AVS-specific and MEV-related yield, all described as variable APY (one source cites 12%+), which aligns with a variable, performance-based profit-sharing model rather than a fixed loan-like return. However, the sUSD/Emerald Card product advertises an approximately 5% yield presented in a fixed-seeming manner, and informal descriptions elsewhere liken base staking to "guaranteed interest" comparable to a bank deposit. This ambiguity means not every reward stream in the ecosystem can be confidently classified as riba-free.
Gharar — How much uncertainty does Solayer involve?
Solayer carries moderate uncertainty: the team and backers are well-documented, but contract-level clarity on slashing and precise reward classification is incomplete. Public audits reduce technical opacity considerably, while unresolved questions around fixed-seeming yields and unclear Islamic-contract framing sustain some ambiguity. On balance, disclosure is reasonably strong but not fully sufficient to eliminate gharar concerns.
Assessment: Moderate Gharar (Material Uncertainty)
Score: 53.1/100
Our methodology examines 15 criteria including team transparency, audit quality, and governance.
Solayer's leadership is named and independently traceable: co-founders Rachel Chu (former SushiSwap core developer) and Jason Li (MPCVault co-founder, UC Berkeley CS), alongside Ryan Clark and Joshua Sum in senior roles. Backing from Polychain Capital, Binance Labs, Hack VC and Maelstrom, with $12-22.5M raised, adds institutional accountability. Some lower-quality sources mistakenly list Solana's Anatoly Yakovenko and Raj Gokal as founders rather than angel investors, a minor sourcing discrepancy that does not undermine the broader picture of a real, identifiable team with public documentation of architecture, though explicit open-source licensing confirmation was not located.
Solayer has been audited by named, dated firms: OtterSec (April and July 2024) and Halborn (endoAVS and pool in August 2024; sUSD in October 2024), with CertiK Skynet also providing an ongoing code-security score. This is a materially better disclosure position than an unaudited protocol. Documentation of the restaking architecture and delegation mechanics is public, though slashing conditions are not detailed in available sources, and the Islamic-contract classification of certain reward streams (particularly sUSD yield) remains unclear, leaving a residual, though narrowed, gharar gap.
Maysir — Does Solayer involve gambling or speculation?
Solayer is not designed as a speculative or gambling instrument; it is an infrastructure protocol offering restaking services and liquidity for Solana validators and AVS operators. Its utility-driven design distinguishes it clearly from zero-sum wagering products, though like most liquid tokens it experiences speculative trading in secondary markets. The core protocol function itself does not constitute maysir.
Assessment: Maysir / Qimar (Gambling)
Score: 48.3/100
Our methodology examines 11 criteria to determine whether Solayer is a gambling instrument or a genuine economic tool.
Solayer provides genuine infrastructure utility: it lets SOL and LST holders (mSOL, jitoSOL, bSOL) earn additional restaking yield by delegating liquid sSOL to Actively Validated Services, supporting real network security and services rather than functioning as a betting mechanism. With over 250,000 wallets having interacted with the protocol and listings on major exchanges like Binance and Upbit, adoption reflects productive use of capital for yield generation and infrastructure support, distinguishing it from maysir-style zero-sum speculation where gains depend purely on others' losses.
Against this genuine utility, Solayer's TVL fell from a peak near $500M to roughly $119M by April 2025, and a 47% price decline coincided with a large scheduled token unlock alongside allegations of coordinated large-holder selling. While no rug pull was confirmed, this volatility illustrates how secondary-market trading and concentrated token unlocks can produce speculative price swings independent of the protocol's underlying restaking activity. Such trading behavior is a feature of market structure and holder conduct rather than of LAYER's own design, and per the guiding principle, third-party speculative misuse does not itself render the protocol's design impermissible.
The Full 27-Point Screening
1. Legitimacy (4 criteria)
| Criterion | Score | Analysis |
|---|
| Team Transparency | 75/100 | Multiple named co-founders and executives (Rachel Chu, Jason Li, Ryan Clark, Joshua Sum) with verifiable backgrounds are documented, though some sources conflate investor Anatoly Yakovenko with a "founder" role. |
| Fraud & Scam Risk | 55/100 | No confirmed rug pull; a founder-adjacent figure was a victim/whistleblower in an unrelated meme-coin scandal, but a 2025 crash drew unresolved "exit scam" allegations tied to token unlocks. |
| Use Case Legitimacy | 78/100 | Restaking infrastructure shows real TVL, hundreds of thousands of active wallets, and a real-world payment product (Emerald Card), indicating genuine utility beyond hype. |
| Ethical Practices | 45/100 | The protocol's own design incorporates a Treasury-bill-yield-backed stablecoin (sUSD), an interest-based element built into the ecosystem rather than a third-party misuse. |
Summary: Solayer has a named, credentialed team and real institutional backing, though a 2025 price crash and unrelated meme-coin controversy involving a team member introduce some caution.
2. Project Operations (9 criteria)
| Criterion | Score | Analysis |
|---|
| Core Protocol Business | 55/100 | Core business is staking/restaking infrastructure, not an inherently prohibited sector, but the built-in interest-bearing stablecoin component tempers this. |
| Transaction Fees | 60/100 | A 50% fee-burn mechanism is documented, though described partly as a "future" gas-token feature rather than fully live today. |
| Treasury Assets | 25/100 | Sources explicitly state sUSD is backed by US Treasury-bill interest yield, meaning interest-bearing holdings are part of the treasury/product design. |
| Revenue Model | 30/100 | Revenue sources include restaking/AVS fees alongside explicit Treasury-bill interest yield from the sUSD product. |
| Transparency | 55/100 | Public docs, architecture pages and audit reports exist, but no explicit statement of open-source licensing was found. |
| Governance | 48/100 | LAYER confers governance rights over upgrades, treasury and grants, but significant Foundation/team/investor allocations indicate real centralisation. |
| Launch Fairness | 45/100 | Sizeable team (17.11%) and investor (16.66%) allocations with vesting show this was not a pure fair launch, despite majority community allocation. |
| Token Distribution | 50/100 | Distribution is documented in detail: over half to community/ecosystem but a third to team, investors and foundation combined. |
| Speculation/Utility Ratio | 45/100 | Token currently has limited live utility (mainly governance) while price action has been dominated by unlock-driven volatility and speculation. |
Summary: The protocol runs a real restaking infrastructure with documented fee mechanics and token distribution, though notable insider/investor allocations limit full launch fairness.
3. Financial Health (4 criteria)
| Criterion | Score | Analysis |
|---|
| Protocol Revenue | 30/100 | Protocol revenue explicitly includes Treasury-bill interest yield from the sUSD product alongside restaking fees. |
| Financial Status | 38/100 | TVL fell roughly 75% from peak and the token suffered a sharp, unlock-linked price crash with dumping allegations, indicating instability. |
| Interest Assessment | 30/100 | The base protocol's sUSD component is explicitly interest-yield-backed, an interest-based element embedded at the protocol level. |
| Audit Quality | 78/100 | Named audit firms (OtterSec, Halborn) with dated reports are documented, plus CertiK Skynet monitoring, indicating real security review. |
Summary: Revenue is generated partly from an interest-bearing Treasury-bill-backed stablecoin alongside restaking fees, and while named audits exist, market stability has been volatile.
4. Token Economics (5 criteria)
| Criterion | Score | Analysis |
|---|
| Token Purpose | 65/100 | LAYER is documented and regulator-classified as a utility/governance token rather than a purely speculative meme asset. |
| Governance Rights | 65/100 | Holders can vote on protocol upgrades, treasury allocation and ecosystem grants per the documented governance scope. |
| Rewards Distribution | 50/100 | Rewards are largely described as variable staking/AVS yield, but the sUSD/Emerald Card product advertises a fixed-seeming yield figure, creating some ambiguity. |
| Speculation Controls | 40/100 | Vesting schedules exist for insiders, but large scheduled unlocks still triggered major price volatility and dumping allegations, showing limited practical control. |
| Asset Backing | 30/100 | LAYER itself has no direct asset backing, and the ecosystem's stablecoin (sUSD) is backed by interest-bearing Treasury bills. |
Summary: LAYER functions as a governance/utility token with variable staking-linked rewards, but its ecosystem's yield products show some fixed-interest characteristics.
5. Staking Mechanism (5 criteria)
| Criterion | Score | Analysis |
|---|
| Mechanism Type | 70/100 | The restaking mechanism is non-custodial and liquid (sSOL is tradable), with no base-layer lockup and documented, if limited, AVS-level unbonding and emergency exits. |
| Islamic Contract Classification | 35/100 | Some descriptions liken staking rewards to guaranteed bank-style interest and the sUSD yield is Treasury-interest-based, leaving the underlying contract classification unresolved. |
| Rewards Structure | 40/100 | Core restaking yield is described as variable APY from staking/AVS activity, but adjacent products advertise fixed-seeming yields, blurring the picture. |
| Documentation | 68/100 | Architecture, FAQ and audit documentation are published in detail describing pool manager, delegation manager and reward accounting. |
| Shariah Alignment | 35/100 | Mixed interest-linked yield sources (Treasury-backed sUSD) and ambiguous contract classification leave a core Shariah question unresolved. |
Summary: Solayer offers a genuine non-custodial liquid restaking mechanism with documented architecture, but its reward structure and Islamic contract classification remain ambiguous due to interest-linked components.
Overall Assessment: Solayer is a legitimate, functioning Solana restaking infrastructure project with real utility and audits, but its interest-bearing Treasury-backed stablecoin component and unresolved staking-contract classification leave open Shariah questions that keep it from a clean compliance profile.
