Solayer’s architecture is designed to provide a robust, flexible, and scalable restaking solution on the Solana blockchain. This document outlines the key components and processes that form the foundation of our protocol, offering insights into how Solayer manages assets, delegates stake, and handles rewards.

Restaking Pool Manager

The restaking pool manager is the core component overseeing asset flow into the protocol. Its key functions include:

  • Processing user deposits of LST or SOL
  • Converting SOL to sSOL-raw
  • Issuing fungible token representations (Solayer assets)

Currently, these Solayer assets are illiquid to facilitate points calculation for the liquidity reward program. Future iterations will introduce liquidity to enhance DeFi composability.

Unbonding and Delegation

  • Solayer assets have no unbonding lockups at the base layer
  • AVS unbonding is managed separately by the delegation manager
  • AVSs can design custom unbonding processes (max 2-day period)
  • Emergency exit mechanism available for AVS failures

Protocol Development Stages

Stage 1: Current Implementation

  • Focus on asset intake and conversion
  • Rewards accounting and distribution

Stage 2: Enhanced Functionality

  • Users can pledge Solayer assets to secure additional networks
  • Delegation to Solayer operators managing AVS nodes
  • Introduction of operator penalties for malicious behavior
  • Users construct restaking portfolios by selecting node operators and SVNs
  • Non-fungible tokens issued to represent user portfolios

Rewards and Accounting

  • Offline calculation of rewards
  • State watcher implementation for tracking deposits and withdrawals
  • Real-time application of additional rewards based on invite relationships

Key Protocol Methods

  1. Restake Method:

    • Permissioned
    • Requires additional server signature
    • Enables deposit limit enforcement in initial epochs
  2. Unstake Method:

    • Non-permissioned
    • Does not require additional Solayer signature

This architecture provides a robust foundation for Solayer’s restaking ecosystem, balancing security, flexibility, and future expandability.
