Guest: Josh from Solayer Labs
Topic: Restaking on Solana, Infrastructure Solutions, and sUSD
Episode Overview
In this episode, we explore how Solayer Labs is revolutionizing Solana's infrastructure through restaking, while differentiating their approach from Ethereum's restaking ecosystem. From transaction throughput optimization to their innovative sUSD stablecoin, we cover the technical and practical aspects of Solayer's solution.
Key Segments
1. Understanding Restaking Fundamentals
Origins of restaking from Ethereum's EigenLayer ($14B TVL)
Why Solana needed a different approach than Ethereum
Evolution from basic staking to liquid staking tokens (LSTs)
How restaking extends capital efficiency
Current Solana staking yields (~7.25% base + Jito MEV rewards)
2. Solayer's Technical Implementation
Stake-weighted Quality of Service (QoS) explanation
How Solayer helps dApps secure reliable transaction throughput
Infrastructure sharing model for smaller protocols
Transaction acceleration without individual validator setup
Receipt tokens and delegation process explained
3. The Innovation of sUSD
First T-bill backed yield-bearing stablecoin on Solana
Implementation of Token-2022 standard
UI improvements for user experience
How sUSD maintains stable value while accruing yield
Integration with major platforms like Phantom and Orca
4. Future Development & Ecosystem Impact
Upcoming exo-AVS implementations
Partnerships with protocols like Sonic and Bonk
Discussion of emerging L2s and rollups on Solana
Vision for scaling Solana's infrastructure
Potential for new use cases and applications
Technical Highlights
Detailed explanation of endogenous vs exogenous AVS
How receipt tokens enable multiple layers of yield
Infrastructure optimization for validator performance
Integration with Jito for MEV rewards
Implementation of Token-2022 for yield-bearing assets
User Benefits
Higher yields through multiple staking layers
Support for favorite dApps while earning rewards
Access to T-bill yields through sUSD
Improved transaction reliability for supported protocols
No need to run individual infrastructure
Notable Quotes
"We're not just a restaking company... we are looking to solve Solana core infrastructure and congestion problems using restaking."
"Each ecosystem would have its own restaking in a different flavor... we can't just copy paste whatever's working in Ethereum."

Quick Terms Guide
AVS (Application-Specific Validator Set): A group of validators dedicated to supporting specific applications or services on Solana. Think of it like having specialized highway lanes for certain types of traffic.
Stake-Weighted QoS (Quality of Service): A system where the more stake you have, the more reliable your transaction throughput becomes. Similar to having a "fast pass" that's proportional to how much you've staked.
Endogenous vs Exogenous AVS:
Endogenous: Services native to Solana's main network (like transaction acceleration)
Exogenous: External services built on top of Solana (like Layer 2s or rollups)
LST (Liquid Staking Token): Tokens you receive when staking SOL that can still be used in DeFi (like JitoSOL or mariSOL)
Restaking: Using already-staked assets to secure additional services, essentially making your staked assets work multiple jobs
MEV (Maximal Extractable Value): Additional rewards validators can earn from optimizing transaction ordering
sUSD: Solayer's yield-bearing stablecoin backed by T-bills, using Token-2022 standard for built-in yield accrual
