My mental model is "what is the least friction to get value from fiat stores to uncensored value transfer rails" on this topic.

> Beginning this fall, you’ll be able to use Chase credit cards to fund your Coinbase account. Beginning in 2026, you’ll be able to redeem Chase Ultimate Rewards Points to fund your Coinbase account. For the first time, points from a major credit card rewards program will be redeemable for crypto rewards. Beginning in 2026, you’ll be able to directly link your Chase account to Coinbase. Chase customers will be able to seamlessly link their bank accounts to Coinbase for another fast, easy way to buy crypto - in addition to all of our existing integrations.
(As of 2023, Chase had 18.5 million checking accounts. In 2024, Chase opened nearly 2 million net new checking accounts. In July 2025, it was reported that JPMorgan Chase holds the largest total deposits among US banks, totaling over $2T; not a JPMC fan by any means, but they are the Goliath of commercial banks as it stands)
It doesn't matter how decentralized it is when you have a centralized merchant account.
First, this product only funds one thing, an account at coinbase. You then have to transfer money to people from whom you would like to buy. No protection from fraud. No nothing. Second, even if it did the real time purchase from the vendor directly from Chase with all the attendant protections, (which it doesn't, but even if it did), we'd really need all banks and credit unions to be using it. If it's just Chase, it's going to be inconvenient for a sizable number of people.
(By "sizable", I mean the majority.)
Chase hasn't been able to stop me from funding merchants they would otherwise not do business with once my funds get to Coinbase, for example. This is the value of stablecoins imho, the ability to move fiat in a low regulation manner through technical performance art. I'd mail cash if I had to, but I'd prefer the stablecoin rails when higher regulation instant payments aren't available to move value due to gating.
