Swift, the global provider of secure financial messaging services, has announced that it has successfully completed an interoperability experiment with Chainlink, the leading decentralized oracle network. The experiment, which was conducted as part of Swift’s Cross-Border Interoperability Programme (CCIP), aimed to demonstrate how Swift messages can be securely and reliably delivered to smart contracts on various blockchain platforms using Chainlink oracles.
Chainlink, the leading decentralized oracle network, has recently announced a new innovation that could revolutionize the way blockchains interact with each other: the Chainlink Cross-Chain Interoperability Protocol (CCIP). The CCIP is a framework that enables any blockchain to securely and reliably access any other blockchain’s data, state, and smart contracts, regardless of the underlying consensus mechanism, programming language, or data format. This means that blockchains can leverage the strengths and capabilities of other blockchains, creating a more interconnected and interoperable ecosystem.
The CCIP is powered by Chainlink’s flexible and modular architecture, which allows developers to customize their cross-chain communication needs according to their specific use cases. The CCIP consists of three main components:

Chainlink Proof of Reserve Nodes: These nodes monitor the reserves of assets on one blockchain and provide proofs of their existence and amount to another blockchain. This enables cross-chain asset transfers, such as wrapped tokens, stablecoins, and NFTs.
Chainlink External Adapters: These are modular components that allow Chainlink nodes to connect to any external API or data source, including other blockchains. This enables cross-chain data feeds, such as market prices, weather data, sports scores, and more.
Chainlink Decentralized Services Networks (DSNs): These are networks of Chainlink nodes that provide decentralized services to other blockchains, such as computation, randomness, identity, reputation, and more.
The CCIP is not only a technical breakthrough, but also a strategic one. By enabling seamless cross-chain communication, the CCIP opens up new possibilities for collaboration and innovation across the blockchain space. Some of the potential benefits of the CCIP are:
Enhanced scalability: Blockchains can offload computation and storage to other blockchains that are more suited for those tasks, reducing congestion and costs on their own networks.
Increased security: Blockchains can leverage the security and decentralization of other blockchains, such as Bitcoin and Ethereum, to enhance their own trustlessness and resilience.
Improved functionality: Blockchains can access the features and functionalities of other blockchains, such as smart contracts, DeFi protocols, NFT platforms, and more.
Greater diversity: Blockchains can benefit from the diversity and richness of data and services available across different blockchains, creating more value and utility for their users.
The CCIP is a game-changer for cross-chain communication, as it enables any blockchain to access any other blockchain in a secure, reliable, and customizable way. The CCIP is a testament to Chainlink’s vision of creating a more connected and interoperable blockchain ecosystem, where each blockchain can leverage the best of what other blockchains have to offer. The CCIP is not only a technical innovation, but also a catalyst for collaboration and creativity across the blockchain space.
The experiment involved sending Swift ISO 20022 messages from a test environment to Chainlink nodes, which then converted them into blockchain-compatible formats and delivered them to smart contracts on Ethereum, Polygon and Binance Smart Chain. The smart contracts then executed various business logic based on the Swift messages, such as triggering payments, updating balances, or verifying compliance. The experiment also showcased how Chainlink can provide bi-directional communication between Swift and blockchains, enabling smart contracts to send messages back to Swift using the same oracle network.
The experiment was a success, as it demonstrated that Swift and Chainlink can interoperate seamlessly and securely, enabling cross-border and cross-platform data exchange and automation. This opens up new possibilities for Swift members to leverage blockchain technology and smart contracts for various use cases, such as trade finance, securities settlement, or cross-border payments. Swift and Chainlink plan to continue their collaboration and explore further opportunities to enhance the CCIP and the future of cross-border interoperability.
