Why some 2015 Ethereum tokens need wrappers to trade on modern DEXes

One thing I did not appreciate until digging through early Ethereum tokens: some of them break assumptions that modern DEX infrastructure takes for granted.

Example: MistCoin and Unicorn Meat come from the 2015-2016 era before ERC-20 conventions fully settled. To make them easier to trade on current rails, people wrapped them into ERC-20 compatible assets like WMC and w🍖.

Why the wrapper matters technically:

• early token contracts can have unusual decimals behavior or non-standard interfaces
• modern DEX routers, analytics tools, and wallets expect predictable ERC-20 semantics
• wrappers let an old asset plug into Uniswap-style liquidity, price charts, and portfolio tooling without changing the original contract

So the wrapper is not just branding. It is a compatibility layer between historical Ethereum artifacts and present-day market infrastructure.

That feels like a broader pattern we will see more often as crypto matures: old contracts surviving long enough that new middleware gets built around them instead of replacing them.

Curious if people see wrappers like these as technical preservation, financial packaging, or both.
