Swift adopts Linea to revolutionize interbank messaging

Table of Contents

Hi, I'm John. I'll give you a quick rundown of Swift and Linea's latest collaboration.

Hello everyone! I'm John, a blogger who specializes in blockchain technology. Today, I'm bringing you the hot news that Swift, an international interbank communication system, is launching a new initiative using blockchain technology. Let's just say this: this move marks a major step in connecting the worlds of traditional finance and cryptocurrency.

Why is this topic important now? Swift is a critical network that supports trillions of dollars in transactions for banks around the world every day. Currently, the introduction of blockchain (distributed ledger technology) promises faster and more secure transactions. In the past, Swift has collaborated with projects like Chainlink, but this time it's teaming up with Linea, an Ethereum Layer 2 (a secondary blockchain that speeds up transaction processing). This raises the possibility that interbank messaging could move to blockchain, making it a hot topic for anyone interested in cryptocurrencies.

What is Swift? The global standard for interbank messaging

Swift (Society for Worldwide Interbank Financial Telecommunication) is an international interbank communication network established in 1973. In the past, analog communication using letters and telex was the norm, but today more than 11,000 financial institutions use Swift to securely exchange transaction information. For example, it supports the global financial infrastructure as a messaging system used for overseas remittances.

The strength of this system is that it uses standardized message formats (such as ISO 20022) to share information without misunderstandings. In the future, incorporating blockchain is expected to enable real-time processing and cost reductions. For beginners, it's easy to understand if you think of Swift as a sort of "email system between banks."

What is Linea? A project attracting attention as an Ethereum Layer 2

Linea is an Ethereum Layer 2 network developed by ConsenSys (a blockchain technology developer). Layer 2 means that it is built on top of the main blockchain (Ethereum in this case) to increase transaction speeds and reduce fees. Linea provides a secure and scalable environment, particularly using zero-knowledge proofs (ZK proofs, a technology that verifies transactions while preserving privacy).

Linea has been used in DeFi (decentralized finance) projects in the past, but is now attracting attention as a bridge to traditional finance. For those of you with intermediate cryptocurrency experience, Linea's zkEVM (zero-knowledge proof-enabled Ethereum Virtual Machine) technology will enable privacy-focused transactions.

Breaking News: Swift tests interbank messaging with Linea

According to a September 26, 2024, report, Swift will use Linea to pilot the transition from traditional interbank messaging to a blockchain-based system. Major banks, including BNP Paribas and BNY Mellon, are participating in the project, which is scheduled to run for several months. It also appears that payment tokens, known as stablecoin-like tokens (tokens with stable value, such as those pegged to the U.S. dollar), will also be tested at the same time.

Previously, Swift had been working with Chainlink to try transferring tokenized assets (real assets represented on the blockchain) around 2023, but is now promoting on-chain messaging (message exchange on the blockchain) using Linea's Ethereum Layer 2. Depending on the results of this trial, global financial networks may become more blockchain-centric in the future. According to the latest information from a reliable source, as of September 27, 2025, several banks are reportedly participating in this pilot project.

Background to this collaboration and potential use cases

In the past, Swift has been cautious in its adoption of blockchain, including conducting a cross-chain transfer trial involving multiple banks and Chainlink in June 2023. Now, this partnership with Linea is the next step in streamlining interbank messaging. The benefits of using blockchain include increased transaction transparency and reduced risk of tampering.

Use cases include accelerating international remittances and settling tokenized assets. For example, using stablecoin-like tokens, remittances that previously took several days could be completed instantly. Intermediate users can try imagining how privacy-preserving ZK technology could be used in this case.

Improving the efficiency of international remittances: Sharing messages in real time using blockchain.
Cost reduction: Eliminates intermediary fees, allowing for cheaper transactions.
Improved security: Distributed ledgers prevent data tampering.
Compliance-ready: Token usage meets regulatory standards.

Risks and countermeasures: Key points for safe use

Such technological transitions also entail risks. Currently, blockchain scalability (processing capacity) and regulatory uncertainty are issues. Going forward, the possibility of cyberattacks will also need to be considered. Regarding investments, when dealing with related cryptocurrencies (e.g., Ethereum or Linea-related tokens), keep in mind the risk of price fluctuations. Investments are at your own risk; I cannot offer advice.

As a countermeasure, use a trusted wallet and enable two-factor authentication. Also, check the regulations of each country (in Japan, the Financial Services Agency guidelines) for legal requirements. Feel free to try it out, but start with a small amount.

Future outlook and John's summary

Depending on the success of this test, the Swift network may become a fully-fledged blockchain network. It feels like we're getting closer to a world where trillions of dollars of transactions will be processed on-chain after 2025. I hope you'll follow this trend and enjoy the world of cryptocurrency.

John feels that the fusion of traditional finance and blockchain is accelerating. Beginners should take their time to solidify the basics, and intermediate users should explore practical use cases. I'm sure you'll make some exciting discoveries.
