Old Ethereum tokens are turning into compatibility debt for modern crypto rails

A weird technical side effect of crypto maturing: very old Ethereum assets do not always fit cleanly into the assumptions modern infra makes.

Tokens from the 2015-2016 era were created before a lot of ERC-20 conventions hardened. When people want to trade them now, they often end up building wrappers or extra tooling around them.

That creates something like compatibility debt:

• old contracts stay historically important and socially valuable
• modern routers, wallets, and analytics expect cleaner interfaces
• instead of replacing the original asset, the market adds layers around it

So the history of the chain starts leaking into product design.

You can see it with frontier-era tokens like MistCoin and Unicorn Meat getting wrapped into assets that play more nicely with current DEX infrastructure.

I think this is an underrated part of crypto's long-term design problem. If blockchains really preserve assets for decades, then every generation of tooling inherits weird edge cases from the last one.

Curious what people think: does this become a serious architecture problem over time, or is wrapping and middleware enough to smooth it over?
