Adrastea Finance

Adrastea Finance is a composable DeFi protocol built on Solana that combines liquid restaking and leveraged yield strategies into a single platform. Founded in September 2023 and backed by a $230,000 pre-seed round from Solana-native communities including Yogg DAO, Midcurve, Monke Ventures, The Chimpions, Dead King Society, and The Hollows, Adrastea targets both passive retail depositors and protocol treasuries seeking optimized yield on their SOL holdings.

What Adrastea Does

The protocol operates across two primary product lines: Liquid Restaking and Leverage JLP. Together, these mechanisms allow users to extract compounding yield from SOL and related assets without actively managing positions or sacrificing liquidity — a persistent friction point in traditional staking and restaking models.

Liquid Restaking and lrtsSOL

Adrastea's flagship product is its liquid restaking token, lrtsSOL. When users deposit native SOL into Adrastea, their capital moves through a routing path — Adrastea → Solayer → AVS (Actively Validated Services) — and users receive lrtsSOL in return. This token is yield-bearing: its value accrues relative to underlying SOL as staking and restaking rewards accumulate, and it trades on-chain under contract address DSsS7nzPv1AhX5UKYMWYSioyd3E8w9QjnTjNA7kyQzVA.

The critical distinction from standard staking is that lrtsSOL remains liquid. Rather than locking capital at the validator level, holders can deploy lrtsSOL as collateral on lending platforms or swap it for SOL at any time on secondary markets, bypassing the epoch-end wait required for native unstaking. Adrastea's smart routing engine automatically delegates to the highest-yielding AVS operators within the Solayer ecosystem, removing the need for users to manually track and shift delegation.

Yield accrues from three stacked sources: base Solayer staking rewards, AVS operator incentives, and partner ecosystem rewards from lending protocols, liquidity pools, and leverage products that accept lrtsSOL as collateral.

Users can also deposit sSOL (Solayer's liquid staking token) and SonicsSOL alongside native SOL, broadening the eligible input assets. To withdraw, users burn their lrtsSOL, triggering unstaking at epoch end. No fees are charged within active epochs.

adraSOL: Liquid Staking Integration

Separately from lrtsSOL, Adrastea launched adraSOL in March 2024, a liquid staking token (LST) built in partnership with Sanctum. The adraSOL validator redistributes 100% of validator commission rewards back to stakers, while holders gain access to exclusive restaking incentives and integrations within Adrastea's broader yield ecosystem.

Leverage JLP

Adrastea's second product vertical, Leverage JLP, enables users to amplify exposure to Jupiter's JLP index token — an LP position that earns fees from Jupiter's perpetuals and spot trading markets. Users can deposit either JLP or USDC as collateral and borrow up to 2x their notional position size, with smart contracts executing predefined actions based on market conditions.

The system features two participant roles: passive lenders supply assets to earn low-risk APY, and boosters borrow against their collateral for amplified yield. Borrowing rates are determined by a utilization ratio — total borrowed divided by total supplied — following a model similar to Aave. The entire process requires a single deposit action, with the protocol handling position maintenance.

Ecosystem Fit and Partnerships

Adrastea sits within the expanding Solana restaking ecosystem, which encompasses protocols like Solayer, Jito, Fragmetric, and others collectively managing billions in delegated SOL. The protocol's Solayer integration places lrtsSOL at the infrastructure layer of this stack: Solayer handles the underlying delegation to AVS operators, while Adrastea issues the liquid receipt token and manages the DeFi composability layer above it.

The protocol's most significant partnership announcement came in October 2024 with Sonic SVM, an SVM-compatible gaming and application chain built on Solana. Sonic became Adrastea's first incentivized AVS partner: users delegating SOL through Adrastea to Sonic's AVS node receive lrtsSOL plus bonus Sonic-specific incentives, creating a dual-reward structure that attracted delegations tied to the $50 million SOL milestone on Solayer.

Adrastea's integration with Sanctum for adraSOL aligns it with Solana's established liquid staking infrastructure, enabling seamless composability with DeFi protocols that already accept Sanctum-issued LSTs.

Security

Adrastea's Leverage JLP smart contracts were audited by Offside Labs, a Solana-focused security research firm, in August 2024. The audit report is publicly available via Offside Labs' GitHub. The protocol also maintains an active bug bounty program for ongoing vulnerability disclosure.

Token

The protocol's native governance token is $ADRA, which is intended to power community voting on protocol decisions, ecosystem incentives, and rewards distribution across Adrastea's dual-yield product suite. As of late 2025, Adrastea signaled an evolution toward a broader infrastructure role — including operating its own Solana validator — positioning $ADRA within a network-level participation model rather than purely DeFi-yield governance.
