A place for developers to talk about building on Farcaster.

Some chains (e.g., Polygon) created a 'dual' ERC-20 representation of their native token (e.g., POL) to avoid a separate wrapper contract (e.g., WPOL).

Bad idea.

It's an unsafe design and it will 100% lead to exploits.

The trouble is that it also requires protocols to block those tokens at the smart contract level (for maximum safety).

Very bad idea and all DeFi projects still uses and will continue using WMATIC 😂

I don't see Polygon PoS doing that, you mean CELO?

That's $WMATIC.

$POL does that.
