How OneBlock works

OneBlock lets anyone launch a token in one transaction and trade it instantly on a fair bonding curve. No presale, no team allocation, no rug — every coin starts on the same curve and is fully tradeable from block one.

Launch & trade in four steps

Connect your wallet

Connect any EVM wallet (e.g. MetaMask) and pick your network — Robinhood Chain or Arc. The app adds the network for you if needed.

Create a token

Give it a name, symbol and image (500×500). Optionally make the first buy (“dev buy”) in the same transaction. Your token deploys as a clean ERC-20 with the full supply held by the curve.

Trade on the curve

Anyone can buy or sell instantly against the bonding curve — no order book, no waiting for liquidity. Buying pushes the price up; selling brings it down.

Price discovers itself

As more people buy, the price and market cap rise along the curve. The community — not a team — decides where the coin goes.

The bonding curve, explained

Every OneBlock token launches with a fixed supply of 1,000,000,000 tokens held entirely by the curve. Pricing follows a constant-product formula with virtual reserves (the same idea behind pump.fun-style curves):

Because the token is a plain ERC-20 and the curve holds every coin the same way, there are no hidden mint, blacklist or pause functions — the contract can’t rug you. Always still do your own research on any token you buy.

Supported networks

Robinhood
Robinhood Chain · gas paid in ETH
Arc
Arc · gas paid in USDC

The same OneBlock contracts are deployed on both networks. Switch between them with the toggle in the top bar; the app automatically shows prices in the right unit (ETH on Robinhood Chain, USDC on Arc).

Fees

1%
Protocol fee per trade (buy & sell)
30%
of that fee goes to the token’s creator
0
Launch fee — you only pay network gas

A flat 1% fee is charged on every buy and sell on the curve. 30% of that fee is paid to the coin’s creator and 70% to the protocol treasury. Launching a token currently costs nothing beyond gas. You always also pay the network’s gas fee, which goes to the network — not to OneBlock. The values enforced on-chain by the smart contracts are always authoritative.

Frequently asked questions

Is OneBlock custodial? Can you take my funds?

No. OneBlock is fully non-custodial. Every action is a transaction you sign from your own wallet and execute directly against public smart contracts. We never hold your tokens, funds or keys, and we cannot move or freeze them.

How much does it cost to launch a token?

The launch fee is currently zero — you only pay the network’s gas fee (a few cents on Arc, and near-zero on Robinhood Chain). You can optionally make a first “dev buy” in the same transaction.

What is a bonding curve?

A bonding curve is a smart contract that always quotes a price to buy or sell a token based on how much of it has been sold. It provides instant, permissionless liquidity without an order book or a market maker. The more people buy, the higher the price climbs.

Can a token be rugged?

OneBlock tokens are clean ERC-20s with no mint, blacklist or pause functions, and the whole supply sits on the curve — so the contract itself can’t rug you. However, memecoins are still extremely volatile and their price can collapse if buyers leave. Never invest more than you can afford to lose.

Which wallets and networks are supported?

Any standard EVM wallet such as MetaMask. OneBlock currently runs on Robinhood Chain (gas in ETH) and Arc (gas in USDC), switchable from the top bar.

Do I need ETH or USDC?

You need the network’s gas coin: ETH on Robinhood Chain, USDC on Arc. That same coin is what you use to buy tokens on the curve.

Can I sell at any time?

Yes. The curve is always liquid, so you can sell your tokens back to the curve at the current price whenever you want (minus the 1% fee).

Are memecoins a good investment?

Memecoins are highly speculative and most go to zero. Nothing on OneBlock is financial advice. Treat it as entertainment and only risk what you can afford to lose.
