Adrastea operates LRT, built on top of Solayer, serving as the gateway to Solayer's ecosystem by securing Actively Validated Services (AVSs) through smart delegation. This enables users to unlock liquidity while amplifying their yield and rewards.
When a user deposits native SOL into Adrastea, it mints an LRT token called lrtsSOL at a specific swap rate, providing seamless access to both staking and liquidity benefits.

lrtsSOL is a liquid restaking token (LRT) on Adrastea, representing a user’s restaked position in Solayer with delegation to AVS. It serves as a receipt token while enabling users to “restake” or “reuse” their SOL via Solayer without locking their restaked assets. This ensures liquidity while maximizing capital efficiency.Users can deposit native SOL and receive lrtsSOL on Adrastea, securing both staking and restaking rewards. Technically, lrtsSOL represents a user's yield bearing SOL means that the value of this LRT token increases relative to the underlying asset; rewards are reflected in the price of lrtsSOL.

Liquid restaking brings additional benefits for the user who wants to unlock their liquidity:
Liquid restaking provides significant advantages for users looking to unlock liquidity from their Solayer AVS delegations and leverage their assets across the DeFi ecosystem. The primary benefit of liquid restaking is that it frees up liquidity from Solayer while still earning rewards. For example, users can integrate with DeFi platforms like BANX lending market, where lrtsSOL can be used as collateral to borrow funds.
While unlocking liquidity is the main incentive, manually optimizing AVS benefits and yield can be a complex and time-consuming process. Adrastea simplifies this by automatically sourcing the best yield and rewards from multiple AVS, ensuring that your assets are always working at peak efficiency. Additionally, through special partnerships with AVS, Adrastea offers extra rewards on top of standard delegation benefits.
Holding sSOL already generates Solana staking rewards and potential Solayer incentives. However, by utilizing lrtsSOL from Adrastea, you amplify these benefits. Adrastea routes your liquidity through the best AVS, optimizing yield and boosting your returns. Pure Restaking: Your SOL → Solayer
Liquid Restaking: Your SOL → Adrastea → Solayer → Best AVS
Withdraws
You can withdraw your Sol back by two options:
Directly through the Adrastea website: By using the unstake and withdraw option.
Swapping lrtsSOL to SOL on secondary markets.
To withdraw your SOL directly via Adrastea, start by navigating to the unstake tab. Since the underlying liquidity is delegated to AVS and staked to Solana validators, you must first unstake it. Because Solana validators cannot unstake liquidity instantly, you’ll need to wait until the current epoch ends. Initiating this process burns your lrtsSOL, and once the epoch concludes, you can claim your SOL in the withdraw tab. The withdrawal tab will also display when the next epoch ends and the status of your unstaking request.
For instant liquidity, you can swap lrtsSOL for SOL on protocols that provide liquidity for the lrtsSOL/SOL pair, bypassing the waiting period. Adrastea partners with various protocols to expand the use cases for lrtsSOL and enhance its liquidity options.
Adrastea will not charge any fees during epochs.
Actively Validated Services (AVSs) are systems that leverage decentralized validation semantics to verify transactions, taking consensus into their own hands and operating independently of the Solana consensus layer. This approach provides additional layers of security and utility.
AVSs can be classified into two categories:
Exogenous AVSs: External systems, such as oracles and bridges.
Endogenous AVSs: On-chain decentralized applications (dApps).
Adrastea is developing an automated routing engine to direct liquidity to the best AVS and optimize rewards. Currently, we manually identify top-performing AVS in collaboration with the community to ensure optimal results. Our initial partner for liquidity delegation is Sonic AVS.
The LRT smart contract is designed to streamline the process, delivering competitive APY and rewards to users efficiently. Below is a flowchart illustrating the Liquid Restaking process on Adrastea:

Here’s the explanation about the LRT process:
User deposits native SOL on Adrastea and it mints lrtsSOL for the user, acting as a receipt from a restaked position on Solayer with delegation to AVS.
Solayer's process involves converting SOL into its native staked form, sSOL, and delegating it to validators recommended by Solayer. These validators then delegate the sSOL to an endoAVS on Solayer, transforming it into a delegated form. The Solayer's dApps mint Delegate Tokens, which serve as proof of stake, allowing users to retrieve their staked SOL and claim associated rewards.
With lrtsSOL, user can deposit into other protocols to access an additional layer of liquidity, enabling them to earn even greater yields and rewards.

LRT enables users to earn yield and rewards from Solayer, delegated AVS, Adrastea, and any other DeFi protocols with which they interact using lrtsSOL.
