Zebec, solana based project has managed to get support of VISA. It's one of the picked up project by the Visa and it'd be likely to be deployed in one of their use cases. In short solana seems to have got the edge over Ethereum and other blockchains on this point. I feel like having use case and getting more people to endorse you from practical standpoint is the way to go. Otherwise relying on fake celebs like Elon, Vitalik type publicity wont help long term.
