The decentralized finance (DeFi) ecosystem is rapidly evolving. With liquidity fragmented across multiple blockchains and rising user expectations, the need for efficient, secure, and user-friendly solutions has never been greater. In this dynamic environment, cross-chain interoperability and regulatory developments are shaping the future of digital finance.
Sergej Kunz, Co-Founder of 1inch, offers valuable insights into the evolution of decentralized exchange (DEX) aggregation, the importance of user security, and the strategic roadmap ahead—including integrations with Solana and Bitcoin.
The Challenge of Fragmented Liquidity
Liquidity in the crypto space is not confined to a single network or protocol. It is distributed across various ecosystems including Ethereum, Layer 2 solutions like Base, and other emerging chains such as Sui and Solana.
Beyond DeFi, a substantial portion of liquidity is held in Bitcoin. While some of this liquidity is managed on centralized platforms, a significant amount remains idle—not generating any passive returns for holders.
Today, earning yield on Bitcoin through DeFi mechanisms is not only possible but increasingly accessible. This reality has informed a broader vision: to expand from DeFi into the wider crypto economy and eventually bridge with traditional finance (TradFi). The tokenization of real-world assets represents a major step in this direction.
Enhancing User Experience with Intent-Based Swaps
Initially, decentralized swaps required users to manually execute transactions and assume all associated risks—including exposure to maximal extractable value (MEV) attacks, where malicious actors could front-run or manipulate trades for profit.
To address this, 1inch introduced an intent-based model. Users simply express what they want—for example, to swap Ethereum for USDC at the best available rate—and the protocol handles the rest. This method, technically implemented through Dutch auction mechanisms, simplifies the process and enhances security.
This approach, known as Fusion Swaps, has influenced the entire industry. Other major protocols have adopted similar models, improving safety and usability across DeFi.
Security remains a top priority. The 1inch Foundation invested significantly in code audits from multiple leading firms to ensure the reliability of its cross-chain swap feature.
Bridging Crypto with Everyday Payments
The vision for practical crypto utility often starts with personal needs. For instance, receiving passive income in stablecoins like USDC naturally leads to the desire to spend those assets in everyday situations—such as buying coffee.
However, converting crypto to fiat traditionally involves multiple steps through centralized exchanges. To streamline this, 1inch partnered with established financial service providers to introduce a crypto card solution. This allows users to spend digital assets seamlessly across supported regions, with expansion plans underway for the US and UAE.
Beyond payments, 1inch is also exploring artificial intelligence (AI) through new products that may launch under a specialized sub-brand.
Security, Compliance, and Decentralization
Protecting users from scams and fraudulent activities is a core focus. 1inch incorporates advanced security tools that screen connected wallets and transaction addresses against known threat databases.
Collaborations with blockchain intelligence firms help identify wallets associated with malicious actors, including those under sanctions or linked to illicit activities. These protective measures are integrated directly into the 1inch non-custodial wallet and decentralized application (dApp).
This proactive approach allows the network to maintain decentralization while prioritizing user safety.
The Role of DAOs in Ecosystem Growth
Decentralized autonomous organizations (DAOs) continue to mature. While community participation is vital, many DAOs are now engaging professional firms to assist with treasury management, grant distribution, and strategic development.
The 1inch DAO supports builders and developers through grants, funding projects that contribute to network growth. These grants enable teams to work full-time on ecosystem development, product innovation, and integration improvements.
Wider community involvement remains essential for sustained innovation and governance.
Integrating Solana and Expanding Multi-Chain Support
The integration of Solana marks a major milestone. It allows users to access liquidity and swap assets across an even broader set of networks without worrying about underlying technical complexities.
This is part of a larger strategy to support seamless interoperability between blockchains. Future integrations will include Bitcoin, Sui, Aptos, and other prominent networks.

The goal is clear: unify dispersed liquidity and deliver a smooth, efficient trading experience regardless of which blockchain the assets reside on.
The Road Ahead: Bitcoin and Beyond
Bitcoin represents the largest pool of liquidity in the cryptocurrency market. Enabling secure, decentralized swaps for native Bitcoin—without relying on intermediaries—is a logical next step.
This will allow users to trade Bitcoin in a non-custodial environment, using smart contracts that eliminate counterparty risk. After Bitcoin, additional high-performance chains will be integrated to further enhance cross-chain functionality.
Frequently Asked Questions
What is a Fusion Swap?
Fusion Swaps are an intent-based trading model that lets users specify what they want to trade while the protocol finds the best execution path. It reduces complexity and minimizes exposure to MEV and other common risks.
How does 1inch ensure security?
1inch conducts rigorous smart contract audits, partners with blockchain security firms, and integrates real-time threat detection systems into its wallet and dApp to protect users from scams and malicious addresses.
Can I spend crypto using 1inch?
Yes, through the 1inch Card—a crypto-powered payment solution currently available in several regions. It enables users to convert and spend digital assets seamlessly in everyday transactions.
What is the role of the 1inch DAO?
The DAO oversees governance, distributes grants to ecosystem projects, and supports developers building on the 1inch network. It helps steer the protocol’s development in a decentralized and community-led manner.
Which blockchains does 1inch support?
1inch currently supports cross-chain swaps across 13 networks, including Ethereum, Polygon, BSC, Arbitrum, and Solana. Plans are underway to integrate Bitcoin, Sui, Aptos, and others.
Why is multi-chain integration important?
Liquidity is fragmented across many blockchains. Multi-chain support allows users to access deeper liquidity, better prices, and more trading opportunities without being limited to a single network.
