77+ Smart Contract Use Cases Enabled By Chainlink

Fundamentally, contracts define the terms and obligations for an exchange of value between two or more independent parties. Historically, a centralized arbitrator is usually required to verify if those terms and conditions are met. However, thanks to the advent of blockchain technology and smart contract applications, we can now replace centralized arbitrators with decentralized infrastructure, reducing counterparty risk and improving operational efficiency.

However, due to the consensus mechanisms of blockchains, smart contracts have no built-in capabilities for interacting with external resources like data providers and API services as a means of verifying the outcome of real-world events happening outside the blockchain. This creates what is known as the blockchain oracle problem and represents one of the greatest limitations to representing everyday contracts on the blockchain.

To overcome this lack of connectivity, hybrid smart contracts use oracles as middleware to retrieve external data inputs, push data outputs to external systems, and perform scalable offchain computations. Not only do oracles serve as a two-way bridge between smart contracts and the outside world, but they also provide a security framework for protecting against any single point of failure such as data manipulation and downtime.

Private, Cross-Chain Transactions for Tokenized Commercial Paper

Tokenized financial instruments like commercial paper require privacy guarantees for institutions handling sensitive transactional data. Traditional privacy-preserving infrastructure is often bespoke, hard to scale, and incompatible with public blockchains. Smart contracts that support confidentiality, alongside cross-chain messaging protocols, can meet these privacy requirements while unlocking programmability and global reach.

Under the Monetary Authority of Singapore (MAS) Project Guardian, ANZ, ADDX, and Chainlink collaborated on a use case supporting the entire lifecycle of tokenized commercial paper. The use case leverages ADDX’s investment platform, ANZ’s Digital Asset Services, and CCIP Private Transactions—a privacy-preserving capability powered by the Chainlink Blockchain Privacy Manager—to expand access to tokenized assets across borders while helping users meet confidentiality requirement.
