Chainlink’s Leading Role in DeFi and Cross-Chain Data

Estimated reading time: 4 minutes

Chainlink has established a prominent role within the decentralized finance (DeFi) sector and cross-chain data connectivity by mid-2025. The company’s infrastructure is used for a range of financial processes and connects decentralized and traditional financial markets.

Currently, over 70% of all total value locked (TVL) in DeFi depends on Chainlink’s price oracle services[1]. As of January 7, 2025, DeFi’s TVL reached $129.37 billion, which highlights Chainlink’s influence in providing accurate data feeds for blockchain-based smart contracts[2]. In May 2025, Chainlink’s market capitalization rose above $20 billion, and the LINK token price reached $15.86[3].

Chainlink’s technology extends beyond cryptocurrency and DeFi protocols. In the field of traditional finance, major institutions are using Chainlink to transfer real-world data—including stock and bond prices—onto blockchain platforms[4]. The insurance industry is also applying Chainlink’s weather data oracles to automate claims, which has led to more efficient operations and reduced costs[5]. Additionally, other sectors such as supply chain management and gaming have integrated Chainlink solutions, signaling broader enterprise interest[6].

In 2025, Chainlink continues to develop new tools to meet changing requirements within the DeFi community[7]. The network has positioned itself as a connector between DeFi and traditional finance, relying on verifiable data to support this role. Some commentators refer to this as a shift toward “Financial System 3.0”[8]. Regions with favorable regulations for tokenized assets are increasing their presence in this space, with Chainlink’s infrastructure often used to issue and manage these digital assets[9].

Forecasts for Chainlink indicate continued development but also point to the volatility typical in the crypto sector. Analyst predictions for LINK’s price by 2030 vary, ranging from $213.1 to $253.51, though such estimates remain subject to market uncertainties[10]. Despite these variables, Chainlink has expressed ongoing plans to enhance its oracle networks and cross-chain systems, maintaining its function as a link between blockchain technologies and external data sources.
