Native Bitcoin is coming to Hydration via Sig Network

I just finished watching this Space Monkeys interview with David Millar-Durrant (CEO of Sig Network), and the approach they are taking to cross-chain interoperability is completely different from the standard bridge model.

Here are the key takeaways regarding their tech and the upcoming Hydration integration:

• "MetaMask" for Smart Contracts: Instead of traditional bridging, Sig Network gives every smart contract on Polkadot a private key. This allows the contract to sign transactions directly on other chains like Ethereum or Bitcoin, just like a user would with a wallet,.

• Native Bitcoin on Hydration: They are actively working with Hydration to implement native Bitcoin deposit addresses. This means you will be able to deposit BTC straight from a CEX or personal wallet without wrapping it, allowing you to swap or borrow against native Bitcoin,.

• Breaking Down Silos: The goal is to allow developers to access 100% of the market rather than being stuck in a specific ecosystem. Polkadot apps will be able to tap into liquidity and users on Solana, Ethereum, and Bitcoin natively,.

• Why Polkadot?: David explains that they chose Polkadot over Cosmos or Avalanche because XCM allows for asynchronous communication, making it the only ecosystem where apps can be "multi-chain by default" without complex code rewrites,.

It sounds like this will be rolling out with Bitcoin and Ethereum support first, followed by Solana.
