Every trade retires carbon.
A carbon-backed token anchored to a real agroforestry plantation. Trading fees flow to an on-chain treasury that automatically buys and retires verified credits — every certificate hashed onto the chain.

What you do here, in three steps
Carbonhood is two things at once: a free tool for working out your own carbon footprint, and a token whose trading fees pay to cancel it out. You can use the first without ever touching the second.
- Step 1
Measure your year
Four questions about how you travel, heat your home, eat, and fly. About a minute. No wallet, no sign-up.
- Step 2
Get your plan
Your footprint in tonnes, the biggest cuts available to you ranked by size, and what it costs to retire whatever is left.
- Step 3
Watch it happen
Follow the treasury buying and retiring real credits, each one with a registry certificate you can check against the chain.
Carbon funding that runs without anyone deciding to be generous
The mechanism is structural. Credits get retired because the contracts route fees there automatically, not because a treasury committee chose to. Follow the money:
Trade HOOD
Every buy and sell pays a 1% pool fee
Fee split
70% of the fee routes to the treasury
CarbonTreasury
Accumulates until 0.05 WETH
Credits retired
Relayer buys verified credits via carbon API

Clear flow from trade to verifiable retirement
What you do and what the protocol does in the background are separate, but they meet in one place: the dashboard proof log.

Example (for clarity)
Trade volume
$10,000
Pool fee (1%)
$100
To treasury (70%)
$70
Protocol share: $30. Retirement mass depends on live carbon price and live ETH/USD at execution time. At around $30/tonne, $70 retires roughly 2.33 tonnes.
Important: plantation baseline and retired credits are reported separately. The dashboard does not blend estimates into verified retirements.
Trade generates fees
Every buy and sell in the HOOD pool carries a 1% fee. 70% of it is routed straight to the CarbonTreasury contract — not to a team wallet.
1% feeTreasury accumulates on-chain
Funds sit in a contract whose only exit is the retirement executor. Neither the team nor a compromised relayer key can redirect them elsewhere.
one exit onlyCredits bought and retired
Once the threshold is hit, a relayer buys verified credits through a carbon API, retires them, and writes the certificate hash back on-chain as proof.

The project's foundation is an integrated agroforestry plantation — a working carbon sink of mixed native hardwood and fruit trees. Purchased credits sit on top of that baseline; the two are always reported separately.

Mixed planting on purpose: hardwoods hold carbon for decades while the fruit and shade crops keep the plot economically alive for its farmers.
Three things the contracts make impossible
Fee ceiling is hard-coded
The tax rate is capped at 1% by a Solidity constant. No owner action can raise it — this token cannot become a honeypot.
MAX_TAX_BPS = 100Funds have one exit
CarbonTreasury has no arbitrary withdrawal and no token sweep. There is no function that sends treasury funds to a team address.
no sweep(), no rescue()Proof, not promises
Each retirement's certificate is hashed onto Robinhood Chain. Anyone can verify the claim against a block instead of trusting a dashboard.
attestRetirement(hash)The things people actually ask
Where does the 1% fee actually go?
The pool charges 1% on every trade. 70% of that goes to the CarbonTreasury smart contract — the address is public and linked from the dashboard. The remaining 30% is the launchpad protocol's share. No part of the fee is paid to a team wallet.
Are the carbon credits real?
Yes — credits are purchased through a carbon credit API and retired in established registries such as Verra and Gold Standard. Retirement means the credit is permanently taken out of circulation and can never be resold. Each retirement's certificate is hashed and written to Robinhood Chain, so you can verify the claim against a block instead of trusting our dashboard.
Is the plantation a verified carbon project?
Not yet, and we say so everywhere it appears. The plantation baseline is a conservative estimate pending registry-grade measurement. It is always reported separately from retired credits and never blended into a single headline number — the two figures answer different questions.
Can the team drain the treasury?
No. The treasury contract has no arbitrary-withdrawal function and no token sweep — funds can only leave to the retirement executor that buys credits. The fee rate is capped at 1% by a hard-coded constant no owner action can raise, and once the fee is enabled it can never be switched off.
How do I buy HOOD?
The token trades against WETH in a locked liquidity pool on the pons launchpad, on Robinhood Chain. Add the network to any EVM wallet, verify the token address from this site, and trade directly from your wallet. The step-by-step guide covers wallet setup, network details, and how to verify a retirement yourself.
