Par Launch β€” print your own dollar

Flywheel Robinhood Chain License

Uniswap SushiSwap LP Locked Backing On-chain

Website X


Par Launch is the Meme Reserve β€” the first launchpad on Robinhood Chain where you can do both sides of money: print your own dollar, or launch your next moonshot. Two full launchpads, one site, one economic engine underneath.

Every other launchpad is the same product wearing a different logo: a bonding curve, a migration event, a "locked" LP you have to take someone's word for. Par Launch is built like a central bank instead β€” a reserve where every asset is either backed by real dollars or locked into its market forever, and where every fee the system earns has exactly one exit: buy the reserve's own token, $PAR, and burn it.

What's inside:

  • πŸ’΅ A stablecoin launchpad β€” anyone can create their own dollar, backed 1 : 1 by USDG (the canonical dollar on Robinhood Chain) escrowed in an on-chain vault. Mint at $1.00, redeem at $1.00, forever β€” with better proof-of-reserves than Tether, checked on every single transaction.
  • πŸš€ A token launchpad β€” 1B fixed supply, the entire supply locked as concentrated V3 liquidity in one atomic transaction. The creator picks the venue at launch: πŸ¦„ Uniswap (the chain's default) or 🍣 SushiSwap (your coin shows up on sushi.com too). Anti-snipe protection, dev buys, on-chain TWAP graduation.
  • βš™οΈ The Flywheel β€” protocol fees from every trade, every stable, every launch converge on one contract that market-buys $PAR and burns it, every 10 minutes, autonomously. It has no withdrawal function. Nobody can stop it, including us.
  • πŸ€– The Par Agent β€” a chat concierge on every page that launches coins from a conversation: it asks for name, ticker, logo, venue and fee routing, previews a banknote, and deploys. No wallet? The house pays the fee.
  • πŸͺͺ Fees to any handle β€” route a coin's creator fees to an X, GitHub or TikTok username that doesn't even have a wallet yet. They escrow on-chain until that person signs in and claims. Launch a dollar for your favorite streamer.
  • πŸ” Money that moves like money β€” buy stables with USDG or straight ETH (one-transaction zap), and swap any stable into any other at exactly 1 : 1 with zero slippage, any size, through the vault.
  • πŸ… Season 0 β€” every launch, mint, trade and seed earns on-chain points that convert to $PAR.

No bonding curves. No liquidity migrations. No admin with a drain button. The site itself has no backend β€” it reads the chain directly, so there is nothing to take down. Everything below is enforced by immutable bytecode, not policy.

πŸš€ Launching a token

Creating a token is creating its market. One atomic transaction:

  1. Deploys a fixed-supply ERC-20 β€” 1,000,000,000 tokens, minted exactly once. No mint function exists afterwards. No owner exists at all.
  2. Opens a concentrated-liquidity V3 pool against WETH at a preset price β€” on Uniswap (the chain's default) or SushiSwap (also tradeable on sushi.com). Same lock, same mechanics, creator's choice at launch.
  3. Deposits the entire supply as a single-sided liquidity position.
  4. Locks the position NFT in the LaunchLocker β€” a contract with no code path to ever withdraw it.
  5. Optionally executes a dev buy in the same transaction, making the creator the first buyer at the opening price, slippage-guarded.

If any step fails, the whole launch reverts. There are no partial launches, and trading opens one block later.

Creators earn a share of every trade's fees, forever β€” accrued on-chain under their address, pull-based, untouchable by anyone else. The protocol's share spins the Flywheel.

Launch modes

Mode What it does
πŸ›‘ Protected Anti-snipe caps for the first seconds of trading: per-transaction and per-wallet buy limits. Applies equally to everyone β€” including the creator β€” and expires automatically, permanently.
🌊 Standard Fully open from the first tradable block. No caps, ever.

Graduation

Graduation is an on-chain TWAP milestone, not a liquidity event: it fires when a token's time-weighted average price sustainably crosses ~16Γ— the launch price. A single-block spike can't trigger it, and the locked liquidity never moves β€” it's a badge earned by holding a price, not a mechanism that touches funds.


πŸ’΅ Print your own dollar β€” the stables launchpad

Anyone can create and back their own stablecoin. It is 100% automated and 100% crowdsourced:

  • True 1 : 1 backing via a proven asset β€” USDG (Global Dollar) on Robinhood Chain. The StableFactory is the vault: minting escrows backing 1 : 1, redeeming burns and returns it. The invariant reserve == supply holds at all times β€” checked on every single mint and redeem, and no admin path can touch reserves. Redeem can never be paused.
  • Buy at $1.00, sell at $1.00 β€” always, straight from the vault, in USDG or with an ETH zap (wrap β†’ swap β†’ mint in one transaction). A small sell fee feeds the Flywheel.
  • Concentrated-liquidity pools built for $1 β€” every stable also gets a V3 pool initialized exactly at the peg with liquidity binned tightly around $1 (the EVM analogue of a DLMM). Creators can seed liquidity that locks in the factory forever.
  • Stable ↔ stable universal swap β€” any two stables sharing a backing asset swap at exactly 1 : 1 through the vault (redeem β†’ mint), zero slippage, any size.
  • Creators earn a share of their stable's pool trading fees; the protocol's share feeds the Flywheel.
  • Launch a dollar for anyone β€” create a stablecoin whose creator fees are escrowed for an X / GitHub / TikTok handle (see below). Your favorite streamer's coin β€” the handle's owner claims when they show up.

Meme-stables with better proof-of-reserves than Tether.


βš™οΈ The Flywheel β€” autonomous buyback & burn

The Flywheel contract has exactly one job and no withdrawal function: everything it receives is spent market-buying $PAR and sending it to the burn address. Its buy-routes are validated on-chain to terminate at $PAR β€” they cannot be pointed anywhere else.

What feeds it: protocol fees from every token trade, every stable sell, every coin created β€” across both markets, on both venues β€” plus anything anyone sends it voluntarily (donations burn too).

Who turns it: an automated keeper cranks the full pipeline β€” collect β†’ sweep β†’ buy β†’ burn β€” every 10 minutes, with site visitors triggering it passively as backup. Every function in the pipeline is permissionless, so even if every keeper died, any wallet on earth could keep the wheel spinning. Nobody can stop it, including us.

Permission is only required where money exits to a person. Every path that ends in a burn is a public button with one hardcoded destination.


πŸͺͺ Fees to any handle

At launch, a coin's creator fees can be routed to:

  • your own wallet (default),
  • any other wallet, or
  • an X / GitHub / TikTok username β€” even one that has no wallet yet.

Handle-routed fees escrow on-chain under keccak256("platform:username"). When that person signs in with the actual provider (OAuth) and proves the handle, the escrowed fees pay out to their wallet and all future fees stream there automatically. Signature verification happens on-chain; the site never custodies a cent.


πŸ€– The Par Agent

A launch concierge that lives on every page. Tell it "make me a stablecoin called Trump Dollar, ticker TUSD" and it will ask for whatever's missing β€” logo, socials, venue, fee routing, seed or dev buy β€” show a banknote-style preview, and deploy on your confirmation.

No wallet? The house pays the deploy fee and routes your creator fees to any wallet or handle you name. Zero-friction, zero-custody.


πŸ… Rewards β€” Season 0

Points accrue on-chain-derived activity from day one: launching coins, backing stables, trading, seeding liquidity. Season 0 points convert to $PAR. No forms, no snapshots to chase β€” if you used the protocol, you're in the book.


πŸ”’ What cannot happen (by construction)

Guarantee Enforced by
Launched-token liquidity can never be pulled Locker holds the LP NFT; no withdrawal code path exists
Token supply can never inflate Minted once at launch; no mint function; no owner
Sells can never be blocked No blacklist, no pause; launch protections cap buys only and expire permanently
Stable reserves always equal supply Invariant checked on every mint/redeem
Stable redemption can never be paused No pause path on redeem; fees hard-capped
Creator fees can never be seized Pull-based claims; only the recorded recipient can withdraw
Flywheel funds can never be withdrawn No withdrawal function; buy-routes validated to end at $PAR
The burn can never be stopped Every pipeline function is permissionless

πŸ§ͺ Battle-testing

  • 142 Foundry tests β€” unit, fuzz, and invariant suites that run against real vendored Uniswap V3 bytecode, not mocks: full launch lifecycles, fee accounting to the wei, anti-snipe windows, vault invariants under fuzzed mint/redeem storms, locker custody, graduation TWAPs.
  • Mainnet-fork verification β€” scripts/verify-flywheel-fork.mjs (33 checks) and scripts/verify-sushi-fork.mjs (18 checks) replay the entire business loop against a fork of the live chain: real deployed bytecode, real USDG, launches, trades, fee collection, burns.
  • Live mainnet proof β€” real launches on both venues, real buys and sells, a real 1 : 1 mint/redeem with real USDG, and real fees accruing to the Flywheel, all verifiable on the explorer.
