How it works

Home base is Arc, Circle's USDC-native L1 (gas is USDC, ~0.5s blocks, no reorgs). The same contracts run on other chains with native USDC and Uniswap v4 — you pick the network when you launch, and the token, tax and rewards behave identically everywhere. Live now: Arc, Base, Arbitrum, Ethereum, Optimism, Polygon, BNB Chain, Robinhood Chain. Coming: Unichain, Avalanche.

Prices, market caps and rewards are always in USDC, whatever the chain. Gas is the chain's native token (USDC on Arc, ETH on Base/Arbitrum/Ethereum, POL on Polygon, AVAX on Avalanche).

On Solana, ONECHAIN runs on Meteora's Dynamic Bonding Curve (audited, permissionless) instead of Uniswap v4: pools are quoted in USDC or SOL (creator's choice; SOL pools trade natively on GMGN, Axiom and Jupiter), same ≈$3k opening and ≈$60k milestone. At the milestone the pool graduates automatically to a Meteora DAMM v2 pool with the liquidity permanently locked. One trade tax (1–10%) applies to buys and sells; it is collected in USDC by the ONECHAIN keeper and split every hour — holders by balance snapshot, buyback & burn, creator, 10% platform — and paid straight to holders' USDC accounts. Gas is SOL. Tokens are plain SPL tokens, tradable in any Solana wallet after graduation (Jupiter).

The Bridge page moves native USDC between chains through Circle's CCTP V2: burned on one chain, minted on the other, attested by Circle in about a minute. No wrapped tokens, no bridge liquidity, no third-party risk. Three wallet confirmations (approve once, burn, mint). If you close the page half-way, the claim step is remembered.

Name, ticker, logo. Choose a buy tax and a sell tax (0–10% each, at least one > 0) and how the tax splits: 💵 holders, 🔥 buyback & burn, 🧑‍🚀 creator, 💧 liquidity (v2). 10% of every tax goes to ONECHAIN. Optional dev buy in USDC, optional vanity address (CREATE2, mined in your browser).

One transaction: the token is minted (1B, no mint or freeze authority), the pool opens at ≈ $3k market cap, the entire supply goes into a one-sided position that is permanently locked (the Portal has no withdraw function and the hook rejects every liquidity removal). Everything is fixed forever.

Trades move the price along the v4 curve. The progress bar runs from the opening tick to the milestone (≈ $60k market cap). Crossing it latches Milestone permanently: the pool does not migrate, liquidity stays where it is, the badge stays on even if the price falls back.

The hook takes the tax in USDC at swap time — wallet transfers are never taxed, so there is no honeypot surface. The Splitter routes it: the holders share is credited per token to every holder (pool, splitter and burn address excluded). Whenever your balance changes (buy, sell, transfer) your pending rewards are pushed to your wallet automatically; you can also claim any time. No keeper, no admin, no claims that expire.

Buyback USDC accumulates; anyone can press "burn it" to buy from the pool and burn. Creator earnings are claimable by the creator only.

ONECHAIN's 10% share is the platform revenue. On Solana the keeper spends it every hour buying $ONE (the ONECHAIN token, on Solana) and burning it — anyone can watch the burns on its page. Revenue earned on EVM chains collects in the Treasury on Arc (other chains bridge to it through CCTP, a public bridge() call run hourly) and is bridged to Solana for the same burn in the next phase — so every chain's volume burns the same token.

For the first 3 seconds after launch every swap pays +20% on top of the tax (the creator's own dev buy is exempt). Bots that snipe block one pay everyone's rewards.

Set a display name and avatar in your vault (signed with your wallet, no gas). The leaderboard ranks the last 7 days by net USDC flow, volume, rewards earned and creators. Points: 1 per USDC traded (buys ×1.5) and 10 per USDC of rewards earned, weekly. Daily top: today's top earners and top paying tokens. All read from on-chain events.
