Everyone’s talking #BTCfi. But @PolynomialFi is actually shipping the rails.

So I tried it myself. I deposited #cbBTC and started earning up to 74% APR, without selling my BTC.

Here’s what I learned 👇

1️⃣ BTC, But Productive

Finally feels like BTC has native #DeFi utility.

I connected my wallet, deposited cbBTC directly, and it just worked.

No wrapping. No bridging. No delay.

2️⃣Short BTC with BTC

I used cbBTC as margin to open a short.

Not because I’m bearish, but because funding was positive.

That means I was getting paid to stay hedged.

3️⃣Long BTC Using BTC

When the market flipped bullish, I flipped long, still using #cbBTC as margin.

So I could go long BTC, using BTC, without selling or swapping anything.

4️⃣Get Paid to Deposit

Even without trading, I’m earning up to 74% APR just for parking cbBTC as margin.

It’s clean passive yield on idle BTC.

5️⃣Funding Farmer Mode

If you’re into stacking points and passive yield:

cbBTC margin = OP rewards + funding yield + trade points.

Triple-yield stacking is very real here.

6️⃣ CEX UX, Onchain Engine

Trading perps on @PolynomialFi genuinely feels like using a CEX:

– 40+ markets

– 50x leverage

– Cross-margin

– Instant execution on their custom OP Stack L2

Try it here: https://t.co/KOLYjgp91b

@PolynomialFi is built on @Optimism , powered by @synthetix_io , and runs its own L2, Polynomial Superchain.

They’ve done $5B+ in volume, and they still don’t have a token.

Feels like early infrastructure quietly dominating the #BTCfi meta.

I’m in. And watching closely.
