ONIX, explained.
ARC · CHAIN 5042One signature launches a coin on its own bonding curve, priced and settled in iUSD— the platform's dollar, backed one-for-one by real deposits and redeemable anytime (how to get it: Get iUSD). The curve fills, the coin graduates to Uniswap V3, and the liquidity is burned — un-ruggable by design. Everything settles on-chain; everything below is on-chain and verifiable.
1Mechanism
- Create. Name it, dress it, deploy. Your coin is live on its own bonding curve in seconds — no presale, no team allocation, fixed 1B supply. The platform fee is a flat 50 iUSD, plus the network's own fee for the deploy — the one thing on this site you pay for yourself (1.2).
- Trade. Every buy and sell settles on-chain against the curve, in iUSD. Price is a pure function of what has been bought — constant-product math, no order book to spoof — and an anti-sniper cap keeps the first minutes fair.
- Graduate. When the curve raises its target (default 500 iUSD), anyone can pull the graduation lever and collect a bounty for it: a Uniswap V3 pool is created at the exact final curve price — zero-arbitrage, nothing skimmed on the way over.
- Open market. The LP position is burned on the spot — sent to the dead address, owned by no one. From then on the coin trades on the open market, and a 1% buy tax on the pool keeps paying the creator forever.
the ledger is public and the liquidity is ash. a very restful arrangement.
Arc charges its network fee in native USDC, which is a different asset from the iUSD everything here is priced in. ONIX holds the first so you only ever need the second.
- COVERED Trading, and everything that gets you paid. Buying and selling on the curve, trading a graduated coin, claiming your creator fees and releasing a graduated coin's accrued fees are all a signature rather than a transaction — including the approvals, which are signed too. Moving dollars in and out through the bridgeis a signature as well. A wallet holding zero native USDC can hold, trade and cash out indefinitely and never touch gas. When the day's covered budget is spent, every one of those controls says so before you click and stops rather than handing you a bill.
- YOU PAY Launching a coin. A deploy costs several times what a trade does, so it is not carried: your wallet needs about 0.008 native USDC on Arc for it. The create form states this before you fill anything in, and stops if your wallet is empty.
- YOU PAY Sending a full curve to Uniswap. Graduation is permissionless and pays a iUSD bounty to whoever lands it — so whoever lands it pays the network fee out of it. While a curve waits, buying is closed but selling stays open, and selling is still covered: the contracts keep the exit unconditional precisely so nobody is trapped by a graduation that has not happened yet.
When the covered route is off, and what to do about each. Coverage is a finite budget on a chain whose gas cannot be bought, so it does run out — and the ways it does are genuinely different. Every control that would have been covered says which one it is, before you click, and none of them can cost you a position:
- Not switched on in this build. Nothing has shipped behind it here. Waiting does not help and nothing is coming — trading works normally from a wallet that holds native USDC on Arc.
- Paused. Ours, temporary — the tank is at its floor or a key is not cleared. It comes back on its own; nothing is spent or stuck meanwhile.
- Today's free buys are used up. The last slice of each day is held back on purpose so that selling and collecting stay free after buying stops. Buying re-opens at midnight UTC. This is the state to understand: the way out never closes behind you, and it closes last by design.
- Today's budget is spent entirely. Resets at midnight UTC. Until then a trade needs a wallet holding native USDC on Arc.
- This wallet has used its own share. The house is still covering other people; one wallet cannot spend the day. Its share resets at midnight UTC, and a different wallet is unaffected.
- We can't reach the service. Then we say that, rather than implying a policy. Nothing is signed and nothing is sent while we do not know.
In every one of those states a wallet that holds native USDC on Arc simply pays for itself and carries on, and a wallet that holds none is stopped rather than sent into a transaction it cannot pay for — the button disables itself and says which state it is in. Nothing is ever locked: balances, positions and fees stay exactly where they are, and the same click works when coverage returns.
Smart-contract wallets are the one exception to all of the above. A Safe, a Coinbase Smart Wallet, or any contract account has no key of its own, and coverage works by accepting a signature in place of a transaction — so nothing here is covered for one. They work normally otherwise: they pay their own network fees, in native USDC on Arc. Every covered control says so at connect time rather than refusing a signature afterwards.
There is no faucet for native USDC on Arc and no market to buy it on — that is a property of the chain, not a policy of ours. If you need some, the short version and the address to write to are on Get iUSD.
The contracts are open source. The Core and the token contract ship their complete source in the repo — every line anyone trades against is public. What runs is on-chain and verifiable. The one exception is the trading dollar itself: iUSD is issued by us against real deposits and redeemable anytime (bridge fees: 1% in, 5% out) — a promise from the team, stated plainly on Transparency rather than buried.
- No mint. Supply is fixed at 1B. A mint function does not exist in the bytecode.
- Renounced.Every coin's owner() is the zero address from birth. No admin keys over your token.
- LP burned. The graduation position is sent to the dead address. Nobody — the platform included — can ever pull liquidity.
- No hidden tax. On the curve, one 1% trade fee, split 50% creator / 50% platform. After graduation, a 1% tax on pool buys with the same split. Both enforced by the contract; sells are never blocked.
- Anti-sniper. A per-wallet cap in the first minutes of every launch keeps bots from eating the bottom of the curve.
- Battle-checked.Repeated adversarial security reviews and a mainnet-fork test suite (graduation solvency proven to the wei) ran before deploy — and the source is open precisely so you don't have to take our word for it.
Builders: a public JSON API mirrors the chain — GET /api/tokens, /api/token/:address, /api/trades/:address, /api/meta/:address and /api/img/:address for aggregators. On-chain, index the TokenCreated, Trade, Graduated and TokenTaxSwept events — the full ABI ships with the open contract source in the repo.
2Economics
- 50 iUSD launch fee. Flat, paid in iUSD, anti-spam. It is the whole platformcost of creating — the deploy also pays the network's own fee, about 0.008 native USDC, and that one goes to Arc's validators rather than to us (1.2).
- 1% per curve trade — split 50% creator / 50% platform. Creators earn from every trade of their coin while it's on the curve.
- 2% at graduation — a one-time migration fee on the raised iUSD; the rest seeds the burned Uniswap position. Whoever triggers the graduation collects a small iUSD bounty.
- 1% after graduation — the coin keeps a 1% tax on every pool buy, split 50% creator / 50% platform, released by a permissionless sweep. Creator earnings never stop.
- 0% reserve burn. A reserve buyback-and-burn engine exists in the Core but is dormant at launch — no reserve token configured, burn share zero. If a platform token ships later, a burn slice of fees can be enabled by the owner for future launches.
