Currently supported DEXs:
- Jupiter (https://t.co/GLYCZLSiSR)
- Raydium (https://t.co/3GocWCW0tU)
- https://t.co/ftSj3lOHBz
The overlay auto-detects which DEX you are on. Premium is calculated based on your actual swap context.
Next: Orca, Meteora, Phoenix, Drift. If you trade on Solana, Harns will cover it.
The Harns extension injects a small overlay on supported DEX pages.
It shows your priority fee, the insurance premium, and what happens if the TX fails. One toggle to opt in.
The extension talks to the Harns backend. The backend talks to the Solana program. The program handles the money. No trust required.

Details soon. The rope is getting shorter.

What if you did not have to visit https://t.co/SX4D2FwwxZ every time you wanted insurance?
What if the insurance was already there, right where you swap? Jupiter. Raydium. https://t.co/ftSj3lOHBz. One toggle. Done.
No new tabs. No separate workflow. Just protection, built into the place you already trade.

Harns is not a dashboard with a token attached.
It is an insurance protocol with actuarial math behind it. Pool reserves. Risk models. Automated refund pipelines.
The goat carries its own rope. It does not borrow one when the cliff appears.
Something is coming that makes holding even more practical. Stay clipped in.

Why hold $HARNS?
Without tokens: base premium rate, 10min refund window. Still works. Still covered.
With tokens: up to 50% premium discount. Instant refunds. LP boost multipliers.
The insurance works for everyone. The economics work better for holders.
/2
Every week, 50% of insurance pool profits buy back $HARNS and burn them.
More users = more premiums = larger pool = more buyback.
The protocol creates demand through usage. Not through promises. Not through influencers. Through math.
Already on it. One of our devs is building an SDK integration for autonomous agents.
The program is signer-agnostic — any wallet can call deposit_premium, bot or human.
So technically it works today, we're just making the DX cleaner.
Will merge it into the main repo once it's ready.

What is inside the Harns docs:
- Insurance pool economics (premium formula, growth condition)
- PDA seed derivation for every on-chain account
- Smart contract instructions (initialize, deposit, refund)
- $HARNS tier table with exact thresholds
This is not a whitepaper. It is the actual system, documented.
