zerosum is a launchpad for tokens backed by real-world assets, built on Robinhood Chain. Every token launches on a bonding curve with a hard reserve floor and price-tracks a live RWA market via Lighter.
zerosum lets anyone launch a token backed by a real-world asset in one transaction. Each token trades on its own bonding curve, priced in a reserve asset, and carries an on-chain reserve floor that ordinary memecoins do not have. Launches are fair: there is no presale, no insider allocation, and supply is minted on the curve as people buy.
When you launch, you choose the real-world asset your token tracks from the markets live on Robinhood Chain - stocks, ETFs, treasuries, and commodities, priced through Lighter. That price is shown on the token, so buyers can always see the real-world market their coin is oriented around.
The token itself is collateralized by an on-chain reserve. That reserve is what gives every zerosum token a floor: a hard price it can never trade below, backed by real value sitting in the vault.
Each token trades on a linear bonding curve denominated in the reserve asset. Buying mints new supply and moves the price up the curve; selling burns supply and moves it back down. The base price is a hard floor - the token can never trade below it.
Every unit of reserve paid in stays in the token's vault, so the vault is always exactly solvent to buy the entire supply back at the curve price. Liquidity is not a promise; it is math enforced by the contract.
Deploying a token takes one signature:
Supply mints on the curve as people buy in, so there is nothing to pre-allocate and no team bag.
Buy or sell any token directly against its curve from the token page. Orders settle instantly on Robinhood Chain and carry a slippage guard, so you always know the worst-case price. Because the reserve backs the curve, there is always liquidity to sell into - you are never stuck holding a token you cannot exit.
When a token's reserve reaches the graduation threshold, the curve freezes and the accumulated reserve seeds a Uniswap liquidity pool, paired with the token at its final curve price so there is no arbitrage gap. The LP tokens are burned, permanently locking the liquidity - it can never be pulled.
From that point the token trades on the open market like any other asset on Robinhood Chain, and the launchpad steps out of the way.
Every token's reserve lives in an on-chain vault. Anyone can read it straight from the contract and verify the backing in real time - the reserve, the supply, and the exact amount redeemable are all public. There is nothing off-chain to trust.
zerosum takes no fee on curve trades - you only pay network gas. After a token graduates, it trades on a standard Uniswap pool with the usual 0.3% liquidity-provider fee, which goes to the locked liquidity, not to us.
zerosum is fully non-custodial. You hold your own keys, every contract is on-chain and verifiable, supply is controlled only by the launchpad, and graduated liquidity is locked at a burn address.
Tokens on zerosum are speculative and can lose value. Nothing here is financial advice. Do your own research.
