How Par Launch works

Par Launch is the meme reserve on Robinhood Chain — a launchpad for 1:1-backed stablecoins and for tokens. Every launch deploys a fixed-supply ERC-20, opens a Uniswap V3 pool against WETH, seeds the entire supply as single-sided liquidity, and locks the liquidity position forever. There is no bonding curve and no migration — tokens trade on real Uniswap from the first block, and the liquidity can never be pulled.

The whole site reads directly from the chain — no backend, nothing to go down.

Launching a token

Connect a wallet, add a name, ticker, logo and (optionally) socials, then launch. In one transaction the token is created, the pool is opened and priced, all 1B tokens go in as locked liquidity, and trading opens. You pay a small launch fee plus gas. If any step fails the whole launch reverts — there are no partial launches.

An optional dev buy lets you be the first buyer of your own coin in the same transaction, with a slippage guard.

Launch modes

Every creator picks one at launch:

Protected — brief anti-snipe caps (per-wallet & per-tx limits) for the first few seconds so bots can't vacuum the launch. Rules apply equally to the creator and expire automatically.
Standard — fully open from the first tradable block, no caps.

Creator fees

The token earns a share (currently 60%) of the Uniswap trading fees on every swap, forever. Fees accrue inside the locked position; anyone can trigger collection into the claim ledger, and only the recorded recipient can withdraw — the admin cannot seize creator fees. Claim yours on the fees page.

Graduation

"Graduation" is an on-chain milestone that fires once a token's time-weighted average price (TWAP over the preset window) sustainably crosses its threshold (~16× launch). It's a badge, not a liquidity event — the locked liquidity never moves, and the TWAP means a single-block spike can't trigger it. See graduated tokens.

Stables — create your own 1:1 stablecoin

The stables launchpad lets anyone create and securely back their own stablecoin — meme-stables galore. It is 100% automated and 100% crowdsourced:

True 1:1 backing in proven assets — minting escrows USDC / USD1 in the factory vault and mints your stable exactly 1:1; redeeming burns it and returns the backing. The on-chain invariant reserve == supply holds at all times, and there is no admin function that can touch the reserve.
Zero intervention, fully on-chain & transparent — creation, minting, redemption, fee collection and flywheel feeding are all permissionless contract calls anyone can verify and trigger.
Concentrated-liquidity pools beat basic AMMs — every stable gets a Uniswap V3 pool initialized at exactly $1, with liquidity binned tightly around the peg (the EVM version of a DLMM). Creators can seed liquidity at creation; it locks in the factory forever with no withdrawal path.

The $PAR flywheel

Every fee the stables system earns feeds $PAR directly: creation fees, redeem fees, and the protocol share of locked-LP trading fees all accrue on-chain and can be permissionlessly swept into the Flywheel contract. The Flywheel has exactly one way for funds to leave: a feed() call that market-buys $PAR through Uniswap and delivers it to the sink (the burn address by default). No withdrawal function exists — fees can only ever become $PAR buy pressure.

More trading → more fees → more $PAR fed → a stronger flywheel. Anyone can turn the crank; nobody can steal it.

Locking supply

Beyond the always-locked liquidity, you can time-lock any token supply you hold in a standalone, admin-less vault — no early exit, no override, locked means locked. Anyone can verify a lock on-chain. Use it to prove you won't dump. Lock at /lock.

Rewards

Activity earns points, computed live from the chain: launching, graduating, generating fees and locking supply. The leaderboard ranks everyone. Points are informational for now.

Trust & safety

Rug-resistant by construction — the LP position is held by an immutable locker with no withdrawal function. Not even the operator can pull it.
Real Uniswap V3 — canonical pools, tradeable anywhere.
No mint / no tax — fixed supply, standard ERC-20.
Factory admin can add/disable future presets and pause new launches only — it cannot mint, touch locked liquidity, alter an existing launch, seize fees, or force graduation.
Tokens are permissionless and unreviewed — locked liquidity does not guarantee value, creators may sell their own holdings, and contracts carry risk. Always verify addresses.
