"The highest risk retail see is losing funds"

Big appreciation to all working on wallet security, account abstraction, dapp security, anti-fraud, etc

The real alpha is not in getting 8% APR instead of 5% APR, it's making sure you don't get -100% APR.

The lack of reversibility and dispute resolution is a key tradeoff with crypto payments, because blockchains can only parse strict objectivity. This is the 
main service that banks, Visa, Mastercard, PayPal etc sell - the tech is very simple and easy.  The only "solution" is to add similar traditional subjective layers on top. Given a majority of real-world consumer crypto payments happen through USDT on Tron via Binance/CEXs, "decentralization" is obviously not the value proposition, rather accessibility to US Dollars, so this may be an avenue worth experimenting with.

As for non-custodial - definitely important to evolve on even if it'll always be a niche userbase. Some low-hanging fruit are mandatory double-checking of addresses, human readable and savable addresses, blacklists of fraudulent addresses, an escrow/undo period, etc can help greatly. These are the common failure cases in traditional payments, and at least anecdotally in crypto too

The question is which layer of the stack to implement this. Reversibility is not an advantage of fiat, cash has no undo button. It’s implemented by the industry built on top of the tech.
