Protocols
apys only integrates with established, audited protocols on Solana. Here's every protocol your funds may interact with, and why we trust them.
How we select protocols
Before integrating any protocol, we evaluate:
- ✓Professional security audit by a reputable firm (OtterSec, Kudelski, etc.)
- ✓Meaningful TVL and real user adoption — not just testnet activity
- ✓Track record through at least one market cycle or major stress event
- ✓Open or verifiable smart contracts that can be independently reviewed
- ✓Active development team with a public security disclosure process
Integrated protocols
Jupiter
Solana's largest swap aggregator and growing lending platform. Jupiter routes swaps through dozens of DEXs to find the best price, and its lending vaults offer competitive stablecoin interest.
- •Largest DEX aggregator on Solana by volume
- •Lending vaults launched with institutional-grade security review
- •Processes billions in monthly swap volume
- •Open-source smart contracts
apys uses Jupiter for all token swaps (SOL → USDC, etc.) and for lending deposits into Jupiter Earn vaults. Swaps go through Jupiter's swap API; lending goes through their vault deposit endpoints.
Kamino
A leading Solana lending and liquidity protocol. Kamino offers automated vault strategies and a lending market with deep liquidity for major tokens.
- •Over $1B in total value locked
- •Automated vault strategies with risk management
- •Multiple independent security audits
- •Used by institutional and retail depositors
apys deposits directly into Kamino lending markets and native vaults using their official transaction builder APIs. Each deposit goes straight to Kamino's smart contracts — no intermediary.
Loopscale
A modular lending protocol on Solana focused on structured credit and institutional-grade lending vaults with transparent risk parameters.
- •Structured lending with clear risk isolation
- •Transparent vault parameters and risk metrics
- •Growing TVL with institutional adoption
- •Active development and security improvements
- •April 2025 price-feed exploit (~$5.8M): funds recovered within 48 hours; five audits published since
apys deposits into Loopscale lending vaults through their REST API. Transactions are built by Loopscale's backend and submitted directly — apys wraps the returned instruction data into a standard Solana transaction for signing.
Audit reports reduce risk but do not eliminate it. Smart contract vulnerabilities can exist even in audited code. apys selects for the highest standard available, but no DeFi protocol is risk-free. See the Risks page for a complete discussion.
