🍣 Bitcoin Is Coming to Sushi as DeFi Platform Expands to ZetaChain Decentralized finance (DeFi) platform Sushi said it is expanding to layer-1 blockchain ZetaChain to add native bitcoin (BTC) support. The addition of ZetaChain, which raised $27 million earlier this year, introduces the first native bitcoin trading in DeFi, enabling users to swap the largest cryptocurrency across 30 networks without wrapping, Sushi said in a release. Wrapping a coin allows it to be used on a different blockchain than the one it was originally issued on.
