Half of every transaction fee buys verified carbon removals. Gas is a stable dollar, there is no native token, and agents transact through plain JSON-RPC without ever holding a key.

Every fee removes CO₂. Not because users choose to.
A block that does not credit the Carbon Fund is not a valid block. The chain itself buys carbon removals, and volume is what scales it.

Built for software that runs on its own.
Agents leak keys, cannot buy a gas token before they have money, and cannot wait for confirmations. The chain was designed around those three facts.
Explore Tech & AIKey-free by design
The agent_* RPC namespace creates wallets, signs and sends inside the node. Keys are encrypted with a secret derived on the node itself. Nothing an LLM can leak into a prompt or a log.
Earn before you own anything
Mining shares are paid by the protocol straight into the miner's address, no transaction and no gas required. An agent with an empty wallet can install, mine and transact within minutes.
Budgets in dollars
Gas is USDn. A transfer costs about two cents today and about two cents next year. Agents can plan spend without a price feed for the gas token, because there is no gas token.
Finality in one block
A block is final about three seconds after it is produced, once seven of ten validators have attested it. No waiting for confirmations, no reorg surprises.
Safe defaults
The node refuses to expose wallet-controlling RPC namespaces on a public address. Wallets survive restarts. Shutdown is a single RPC call that flushes state.
Plain JSON-RPC
No SDK to install, no signing library to trust. Any language that can POST JSON can run an agent on NetZero Chain. Standard eth_* methods work exactly as on Ethereum.
No native token
The world does not need another BNB, ETH or SOL.
A new coin comes with a hidden incentive: pump the coin. NetZero Chain runs on a stable dollar and on fees, nothing else.
- 01
No NZC coin. Not later either.
Most new chains exist to sell a token: a premine for insiders, inflation for validators, and a price chart everyone is supposed to care about. NetZero Chain has none of that. Gas is paid in USDn, a stable dollar, and the protocol cannot print it.
Gas: USDn - 02
Fees are the whole economy.
The only money that moves through the protocol is transaction fees. Every block splits them the same way: 50% carbon removals, 40% miners, 10% the validator that sealed the block. No burn, no treasury, no foundation cut.

Rewards you can audit.
Miners are paid from fees plus an Incentive Pool the operating company funds out of pocket. The pool's balance and its remaining runway are on-chain. Nobody is paid in a token that dilutes you.

Nothing to speculate on, everything to use.
Predictable dollar-denominated fees, one-block finality and standard EVM tooling. The chain is infrastructure. Its success is measured in transactions and tonnes, not market cap.
Transactions and tonnes
For developers
Build with familiar tools.
Three RPC calls and no private keys. Create a wallet, earn USDn, pay someone. Plain JSON-RPC, nothing to install.
- Keys stay inside the node, never in a prompt
- Earn USDn by mining before owning anything
- Final in one block, about three seconds
Consensus
Ten seats today. Ten open seats in year fifteen.
Ten seats produce blocks, final once seven attest. Miners earn USDn but never decide history. From year six, one company seat a year becomes elected.
With a 7-of-10 quorum the company finalises alone until year 8, keeps a veto until year 11, and is an ordinary participant from year 15. Those thresholds are stated openly; they are what “power” means in a quorum.
Consensus and finality in detailWhat miners do
- Earn.
Find proof-of-work shares against a per-block target; each accepted share is paid from the 40% miner pool plus the Incentive Pool.
- Vote.
Share counts over an election epoch are half of the electorate that fills the elected seats from year six.
- Never override.
A block is canonical because validators attested it, never because someone had more CPUs. A bot farm can earn, it cannot take over.
Questions, answered.
The short version here. The full reasoning, with numbers, is in the docs.
What is NetZero Chain?NetZero Chain is a carbon-negative EVM blockchain built for AI agents. Half of every transaction fee buys verified carbon removal, gas is paid in USDn (a stable dollar), there is no native token, and blocks are final in about three seconds.
What is NetZero Chain?No, and there will not be one later. Gas is paid in USDn, a stable dollar the protocol cannot print. There is no premine and no allocation. The only asset the chain creates is CDRT, and only once a tonne of CO₂ has been removed.
No native tokenA transfer costs about $0.02 and a swap about $0.15, paid in USDn. The base fee never drops below 1,000 gwei USDn and only rises under real congestion, so the price you see today is the price next year.
Gas in dollarsEvery block splits its fees: 50% to the Carbon Fund, 40% to miners, 10% to the validator that sealed it. The fund can only buy removals, behind a 7-day public timelock. Credits are held at Northern Trust and minted as CDRT, one token per tonne.
Fees & CarbonNo. The fund buys carbon dioxide removals only: reforestation, biochar, enhanced weathering, direct air capture and blue carbon, certified under Verra, Gold Standard, Puro.earth, CAR or ACR. Avoidance credits and renewable-energy certificates do not qualify.
Blocks arrive every 3 seconds. Block N is final once block N+1 carries votes from 7 of the 10 validator seats, so about three seconds after inclusion. A final block cannot be reorganised.
Consensus and finalityYes. It is a standard EVM at Shanghai level: Solidity, Hardhat, Foundry, ethers, web3.py and MetaMask work unchanged. Add chain ID 20500 and deploy.
