Contracts

Addresses, verified source, and the exact powers of the owner.

Lancio is three contracts on Robinhood Chain, plus one token contract per launch. None of them is a proxy, so none can be upgraded. The source is verified on Blockscout: open any address below to read it.

Every token launched on Lancio is its own contract: a standard ERC-20 with 18 decimals and a fixed supply of 1,000,000,000, minted once. It has no owner and no mint or burn function. Its address is on the token's page.

Admin powers

The launchpad has an owner. Ownership can be handed over in two steps, but never renounced. The owner can do exactly two things:

  • change the treasury address that receives Lancio's share of fees;
  • pause and resume the creation of new tokens.

The owner cannot:

  • stop or pause trading, on any curve or in any pool;
  • change any parameter, such as supply, curve, fees, launch window or graduation threshold, for any token;
  • touch the ETH on a curve, a creator's unclaimed fees, or a locked position;
  • upgrade any contract.

The locker and the hook have no owner at all.

These guarantees hold at the contract level. They rely on Robinhood Chain itself, which is covered in Risks.
