Why is so much BTC just sitting idle?

Well for a long time most DeFi routes require wrapping or bridges. Both of these break Bitcoin’s core principles.

Does it always has to be like that? Actually no.

@build_on_bob (Bob) is a hybrid L2 that lets you earn real yield on real BTC

There's no wrapping and no custody trade-offs involved.

The blurb:

BOB fuses the strengths of Bitcoin and Ethereum.

- BTC provides security and value

- ETH handles smart contracts + liquidity

BOB is the layer that makes them work together.

It’s not a bridge. It’s a trust-minimized system using atomic swaps + threshold sigs.

The testnet’s already live (Aurelia), and it feels like BOB is actually solving the “Bitcoin in DeFi” dilemma.

Not by replacing BTC, but by respecting it (Real BTC. Real yield. Real custody)

Game-changer? 👀
