crypto payments are gaining momentum, especially crypto cards - @Mastercard acquiring stablecoin rails company @BVNK - dedicated payments chains (@Tempo, @Arc) - $300B+ in stablecoin value onchain let's look at the key considerations that will take adoption to the next level ↓

here, @mastercard show the process of paying for a pizza using a crypto-backed card what isn't shown is that swapping crypto for the fiat that's used to pay the restaurant can be seen by anyone. cards are linked to wallets; if someone works out the address linked to a card, they can see its entire purchase history

block explorers have begun creating dashboards for crypto card payments, with some even assigning categories to transactions and displaying account balances not comfy

so we need a privacy solution that keeps all this private however, current privacy solutions don't meet the requirements of payments companies, who require security, flexibility, performance, and compliance-compatibility:

firstly, they need to be secure, reliable, and fast dedicated payments chains need to process a huge number of transaction. a privacy solution needs to be able to keep up many privacy techniques currently used to bring privacy to onchain transactions are too slow

secondly, payments companies have their own infra and workflows. a privacy solution needs to be flexible enough to be integrated seamlessly minimal overhead, custom integration

finally, payments companies need to meet regulatory standards this means that they must be able to grant view access to third parties like regulators and auditors this is key

to summarize: privacy protocols for payments providers operating onchain must be: ✅ secure + fast ✅ flexible + customizable ✅ compliance-friendly ...like Inco
