DeFi on Solana 2026: Jupiter, Raydium, Kamino, and Marinade Explained
The DeFi landscape on Solana — DEX aggregator Jupiter, AMMs Raydium and Orca, lending with Kamino and MarginFi, liquid staking with Marinade and Jito. How the protocols fit together.
DeFi on Solana
Solana’s DeFi ecosystem is one of the most active across all blockchains. This article explains the key protocols and how they connect.
In plain words: Imagine all the financial services a bank offers — trading, lending, earning yield — run instead by open programs on a public blockchain. No company controls them, anyone with a wallet can use them, and no one can lock you out. That’s DeFi. On Solana, low fees and fast transactions make it especially accessible. This article covers the concepts and protocols — the guided, step-by-step path is in the Guide.
Core Idea
DeFi (Decentralized Finance) refers to financial applications that run entirely on smart contracts — self-executing programs on the blockchain — with no central operator. That means swaps, loans, and yield are available around the clock, transparently, and without censorship. The trade-off is real self-custody: no support line, no reversals. Mistakes stay on-chain.
DEX Aggregators
Jupiter
Jupiter is the leading DEX aggregator — a service that compares prices across every available trading venue — on Solana. It automatically scans every available liquidity source and finds the best price for your swap.
- Function: Aggregates liquidity from 20+ DEXes
- Features: Limit orders, DCA (Dollar Cost Averaging — automated interval buying), perpetuals
- Token: JUP (governance token)
Raydium
Raydium is one of the largest Automated Market Makers (AMM) — a protocol that sets prices via mathematical formulas rather than a traditional order book — on Solana.
- Function: AMM + liquidity pools (capital pools from which swaps are filled)
- Features: Concentrated liquidity, AcceleRaytor (launchpad)
- Token: RAY
Lending & Borrowing
Kamino Finance
Kamino offers lending, borrowing, and automated liquidity management — depositing assets to earn interest, borrowing against collateral, and algorithmically managed liquidity positions.
- Understand lending and borrowing mechanics
- Deposit SOL or stablecoins as collateral
- Categorize automated liquidity strategies
MarginFi
MarginFi is a decentralized lending protocol with a focus on risk management.
- Isolated risk pools
- Different collateral tiers
- Integration with other Solana DeFi protocols
Liquid Staking
Liquid staking — staking SOL while receiving a tradable derivative in return — is a core DeFi primitive on Solana:
| Protocol | Token | Historical Reward Range |
|---|---|---|
| Marinade | mSOL | 7-8% |
| Jito | JitoSOL | 7-9% |
| BlazeStake | bSOL | 7-8% |
Risks in DeFi
DeFi opens up technical possibilities, but it also carries significant risks:
- Smart contract risk: Bugs in code can lead to losses
- Impermanent loss: Liquidity providing can result in value loss versus simply holding
- Oracle risk: Faulty price data can trigger liquidations
- Regulation: DeFi regulation varies by jurisdiction and is still evolving in many regions
What This Means for You
Solana’s DeFi protocols are publicly accessible and technically mature. Access and risk rest entirely with you — no provider bears liability and transactions are generally irreversible. Understanding the protocols and their mechanics is a prerequisite before deploying any capital.
Concept clear? Now the guided path. This article explains the principles. The structured, step-by-step walkthrough — with context for your situation — is in the Solana Guide.
