Recently, I discovered a pretty practical feature—the idle money in my card can now automatically earn interest.

There's no need to specifically transfer it to some vault for locking, nor do I have to constantly move funds back and forth. The balance just sits there, quietly generating returns, and I can spend it whenever I want. Both liquidity and yield are available at the same time—it feels like having a 24/7 worker in my wallet.

The underlying system uses a non-custodial architecture, so I still retain control over my assets. This seamless, passive earning experience is really smooth, finally saving me from all those tedious manual operations I used to do.
