Adrastea Finance (ADRA)

Adrastea Finance is a composable DeFi protocol built on Solana that packages advanced yield strategies into forms accessible to passive investors and protocol treasuries. Founded in 2023 and operated by Amalthea Inc, the protocol centres on two primary mechanisms: Leverage JLP, a lending-and-borrowing product built around Jupiter's JLP index token, and Liquid Restaking, which unlocks liquidity from staked positions inside Solayer's Actively Validated Service (AVS) ecosystem. The ADRA token is planned for governance and protocol incentives and has been distributed via airdrop campaigns.

Leverage JLP

Jupiter's JLP token is an index asset that earns fees from Jupiter Perpetuals trading activity. Adrastea's Leverage JLP product lets users amplify exposure to JLP yield without active management.

The mechanism separates participants into two roles. Passive lenders deposit single assets — USDC or JLP — into isolated lending pools and earn interest with no liquidation risk and no impermanent loss. Their returns come entirely from the interest paid by the second participant type: Boosters.

Boosters are yield seekers who want amplified JLP exposure. They deposit collateral (JLP or USDC depending on the pool) and borrow up to 2x their notional value from the passive pools. Those borrowed funds are used to purchase additional JLP via Meteora Swap, giving the Booster a leveraged long position on JLP's underlying yield. All position details — borrowed amount, average entry price, and accrued fees — are recorded on-chain in what Adrastea calls Ledger Positions, enabling transparent, auditable risk tracking.

The interest rate model is inspired by Aave's dual-slope structure. Below an optimal utilization threshold, borrowing rates rise gradually; above it, rates increase sharply to incentivize liquidity restoration. Boosters pay only the borrow APY — there are no protocol-level fees applied during epochs, though a 0.1% fee applies to passive pool withdrawals. Slippage on Meteora swaps is capped at a maximum of 3%. Each pool pair is isolated, so a problem in one pool does not cascade to others.

Liquid Restaking and lrtsSOL

Adrastea partnered with Solayer in December 2024 to launch lrtsSOL, a liquid restaking token representing deposited SOL delegated to Solayer's AVS network. Users deposit native SOL, sSOL, or SonicsSOL and receive lrtsSOL in return, which automatically accrues rewards from three sources simultaneously: base Solana staking yields, AVS rewards (currently routed to Sonic AVS), and additional incentives from Adrastea's DeFi partner network.

The core advantage of lrtsSOL over plain restaking is liquidity. Standard restaking locks capital during delegation. lrtsSOL holders can deploy their token across Solana DeFi while still earning the full restaking reward stack — for example, using lrtsSOL as collateral on BANX lending market to borrow against it while yields accumulate. Users who need instant liquidity can also swap lrtsSOL on secondary markets rather than waiting for the epoch-based withdrawal cycle, which follows the standard Solana validator constraint of one to three days.

AVS routing is currently managed manually by the team based on performance data, with Sonic AVS selected as the primary destination. An automated routing engine is listed as a roadmap item. Reward allocation is proportional to each user's lrtsSOL balance and duration of holding, calculated transparently on-chain.

Ecosystem Integrations

Adrastea is built to compose with existing Solana infrastructure rather than replicate it. Key integration partners include:

• Meteora — DEX infrastructure for executing Boost swaps
• Solayer — restaking and AVS delegation layer for lrtsSOL
• BANX — lending market accepting lrtsSOL as collateral
• Sanctum — LST tooling within the liquid staking layer
• Jupiter — source of JLP, the primary collateral asset for Leverage JLP

The protocol also participated in community education through a "DeFi 101" initiative alongside Orca, Marginfi, Sanctum, and Solayer, positioning itself as a gateway product for newer Solana users exploring yield strategies.

Security and Audits

Adrastea commissioned a Smart Contract Security Assessment from Offside Labs, completed in August 2024, covering the Leverage JLP strategy contracts. An active bug bounty program accepts critical vulnerability submissions via the project's Discord. The protocol operates non-custodially — users connect their own wallets and retain control of assets — but the documentation is explicit that smart contract risks cannot be fully eliminated, particularly given the multi-hop interaction chain (Adrastea to Solayer to validators to AVS) involved in the liquid restaking path.

Team and Funding

Amalthea Inc, a Panamanian entity, is the registered operator. No public team member names are disclosed in official documentation. The protocol raised $230,000 in a pre-seed round backed by Solana-native investment communities including Yogg DAO, Midcurve, Monke Ventures, The Chimpions, Dead King Society, and The Hollows. No institutional venture capital is listed among early backers.

Token and Airdrop

The ADRA token is designed for governance, rewards, and protocol incentives. The team has run at least two airdrop epoch campaigns — Liquid Restaking Epoch 1 ran from November 2024 through mid-2025, rewarding early depositors and restakers; Epoch 2 followed. Full tokenomics, including supply, distribution schedule, and vesting details, had not been publicly disclosed as of mid-2025.

Solana Ecosystem Fit

Adrastea targets a gap in Solana DeFi: passive, capital-efficient yield that does not require active position management. Both core products are designed for users who want amplified returns without constant monitoring. Leverage JLP expresses a bet on Jupiter Perpetuals fee revenue with minimal overhead; lrtsSOL stacks Solana staking, AVS, and DeFi partner rewards into a single liquid token. The protocol's composability with established Solana primitives — Meteora, Solayer, BANX, Sanctum — means users are not locked into a proprietary stack but can move capital freely across the ecosystem while earning through Adrastea's yield infrastructure.
