According to CoinMeta, Chainlink helps financial institutions integrate their systems and key signing infrastructure into the SWIFT blockchain ledger through a runtime environment ( CRE). Banks retain control over their transaction authorization keys while adopting a 24/7 tokenized payment workflow. The SWIFT ledger coordinates cross-bank fund transfers between participating institutions based on tokenized deposits, covering overnight and weekend periods, with final settlements completed through existing mechanisms such as the Real-Time Full Settlement System ( RTGS ). As of SIBOS, 2025, the SWIFT ledger has connected more than 11,500 financial institutions across over 200 global markets.
