Not much Rik for SWIFT & the upcoming JPM Coin — while the former has been a settlement system in place for years, they have been trying to experiment with DLT to somehow make the process a little more efficient but haven’t been successful, while the latter is just the digitization of the banking transfer process (for now) apart from using their private Quorum blockchain. XRP & Stellar on the hand are using the decentralized networks to make cross border payments with some success but both projects are backed by centralized Corporations like Ripple & IBM. Here’s a link to my previous piece which might be useful. https://medium.com/datadriveninvestor/cross-border-payment-systems-swift-ripplenet-or-bww-891d5add58bf
