UNISWAP integrates SOLANA: a strategic breakthrough in cross-chain transactions and API upgrades
TL;DR
Uniswap officially integrated Solana support on October 15, 2025, achieving its first non-EVM chain integration via the Jupiter API. Users can now trade over 1 million SPL tokens within a unified interface. This integration, combined with the "Compact" cross-chain system, marks a significant shift in DeFi from single-chain fragmentation to multi-chain unification, targeting the $140 billion DEX opportunity within the Solana ecosystem.
Core technology implementation
Integration architecture and mechanism
Uniswap's Solana integration is not a native protocol deployment, but rather a front-end API-driven integration. Users select Solana through the web application's network switcher, connect a compatible wallet, and transactions are routed to Solana's major DEX liquidity pools via the Jupiter Ultra API.
Core technical features :
- Routing Engine : Uses Jupiter Metis v1 routing engine to optimize transaction paths and reduce slippage by splitting transactions
- Error handling : Integrate Jupiter-specific error codes (such as -1000 network failure) to provide user-friendly error conversion
- Cost advantage : Solana transaction fees are approximately $0.00025, significantly lower than Ethereum
Support wallet ecosystem :
- Phantom (Solana DeFi mainstream)
- Solflare, Backpack
- Ledger hardware wallet support
- Wide compatibility through WalletConnect
API upgrades and developer support
Uniswap Trading API expansion : Support for Solana is coming soon. Developers can access Jupiter routing quotes through the /quote endpoint with the parameter chainId: solana . The API already supports 14 EVM chains, and Solana support will further enhance multi-chain development capabilities.
Jupiter Ultra API Integration : Uniswap became the first major adopter, using the Jupiter v6 API on the backend for bot compatibility, new error codes (such as -2003 timeout) and Solana transaction payload validation.
Market data and performance analysis
Trading volume and liquidity
| date | Raydium | Orca | Meteora | Solana Total DEX Volume |
|---|---|---|---|---|
| October 15 | $848 million | $816 million | $1.54 billion | ~$3.2 billion |
| October 16 | $784 million | $811 million | $844 million | ~$2.44 billion |
| October 17 | $784 million | $811 million | $844 million | ~$2.44 billion |
Key Metrics :
- Solana ecosystem transaction volume reaches $140 billion in 30 days
- Processed $450 million in trading volume within 10 minutes on the first day of integration
- Jupiter accounts for approximately 25-35% of Solana's routing volume
UNI Token Performance
| Time Node | price | 24-hour changes | Key Events |
|---|---|---|---|
| Peak on September 12 | $10.19 | +5.9% | v4 TVL exceeds $1 billion |
| September 24 | $7.90 | -22.5% | The Compact is released |
| October 15 | $6.58 | -0.6% | Solana Integration Launched |
| October 17 | $6.07 | -8.45% | Impact of market correction |
UNI tokens have a market capitalization of approximately $3.65 billion and a 24-hour trading volume of $298 million. Price fluctuations during the integration announcement period were primarily driven by macroeconomic factors, with a 37% drop from its September peak to October 17th, reflecting regulatory uncertainty and competitive pressures from DeFi.
TVL and Ecosystem Comparison
Solana Ecosystem TVL Distribution :
- Jupiter: $3.23 billion (29% share)
- Raydium: $2.07 billion
- Orca: $419 million
- Total: $11.23 billion
Uniswap's global TVL is US$4.5 billion. Solana integration aggregates existing liquidity, with no direct TVL transfer in the initial stage. It may attract 5-10% of Solana's trading volume in the long term.
Social Emotions and Ecological Responses
Community response
Social media reactions were generally positive, highlighting the reduced fragmentation and improved user experience in DeFi. Users praised the unified interface design, which eliminated friction in switching between the Ethereum and Solana ecosystems. Official messaging emphasized the convenience for average users, positioning it as a victory for multi-chain portfolio management.
Competitive Ecosystem Collaboration
Symbiotic Relationship with Jupiter : Jupiter officially celebrated the partnership, with its Ultra API providing efficient routing for Uniswap. The community sees this as "Solana on Uniswap, powered by Jupiter"—a collaborative growth effort, not a zero-sum competition.
Impact on Solana’s native DEX :
- Raydium and Orca benefit as underlying liquidity providers
- Expand user reach through front-end aggregation
- Strengthening Solana’s position as multi-chain DeFi infrastructure
"The Compact" cross-chain system
Technical Architecture
The Compact v1, released on September 24, 2025, is an open-source, cross-chain interoperable system based on ERC-6909, developed in collaboration with LI.FI and Rhinestone. The system addresses cross-chain fragmentation through reusable "resource locks" and programmable commitments.
Core components :
- Allocators : Authorize resource usage to prevent double spending, supporting trustless and hybrid signature modes on the chain
- Arbiters : Verify the fulfillment of rights applications and customize trust/speed requirements
- Tribunal : A non-custodial settlement engine that coordinates asynchronous execution through auctions and verifiable proofs
- Emissaries : Smart Wallet backup validator, supporting key rotation and multi-signature
Strategic significance
The Compact, deployed on Ethereum mainnet, Unichain, Base, and Arbitrum, provides technical support for UniswapX cross-chain transactions. By abstracting complexity and reducing execution risk, it aims to unify the $150 billion+ DeFi TVL and avoid the limitations of single-host custodial solutions.
Competitive landscape and strategic impact
Shift in market positioning
Uniswap has transformed from an "Ethereum DEX" to a "cross-chain liquidity layer," solidifying its leadership in DEXes (67% share of L2 trading volume, $143 billion in August). By integrating Solana's speed advantage with Ethereum's deep liquidity, Uniswap has established a differentiated competitive advantage.
Comparison with competitors
vs Solana native DEX :
- Jupiter: Monthly trading volume exceeds $100 billion, Uniswap collaborates via API rather than competing directly
- Raydium/Orca: Focus on Solana-specific functions, Uniswap provides cross-chain bridging capabilities
- Competitive advantages: Brand influence and institutional API integrations (such as CoinRoutes)
vs other aggregators :
- The Compact primitive offers greater composability than competing Permit2-based products.
- v4 Hooks feature (2500+ pools) leads 1inch and OKX DEX in programmability
DeFi Ecosystem Impact
This integration accelerates DeFi’s maturation towards interoperability and scalability:
Liquidity and Efficiency : Unify and decentralize $150 billion TVL, reduce costs by 95% through Unichain, and support new asset classes such as RWA
User adoption : Simplified multi-chain UX (single application coverage), lower barriers to entry for retail and institutional users, and legal clarity for DAOs to support compliant development
Ecosystem Growth : Promoting a hybrid model (Ethereum liquidity + Solana speed) to challenge chain silos. V4's rapid TVL growth (reaching $1 billion in 177 days) demonstrates potential for fee accumulation.
Risks and Challenges : Bridge vulnerability risk, volatility impact, and regulatory pressure. Permissioned DeFi competition may further fragment the market.
in conclusion
Uniswap's Solana integration and The Compact system mark a strategic shift in DeFi from "chain-specific" to "chain-agnostic," aiming for a TVL exceeding $200 billion by 2026 through technological innovation and ecosystem collaboration. This initiative strengthens Uniswap's position as a "DeFi SaaS," but the key to success lies in security assurance and widespread adoption. While the short-term benefits will primarily come from improved user experience, the long-term value lies in building a unified multi-chain liquidity infrastructure.
