# Padro > Where Projects Begin. Discover. Prepare. Launch Padro is a launch transparency launchpad on Robinhood Chain (chain id 4663). Creators publish a structured launch profile (summary, venue and date, allocation adding to 100%, vesting, controls held or not, open risks, links). The profile hash and a small header are stored by the PadroLaunchLedger contract and the full JSON text is emitted in its Published event, so every version can be rebuilt from the chain. It does not create, sell or custody tokens. ## Pages - https://padro.live/launch: launchpad workspace (draft in the browser, publish from the wallet) - https://padro.live/discover: directory of published profiles (preparing / launched) - https://padro.live/readiness: configuration checks for any Robinhood Chain token - https://padro.live/token: $PADRO - https://padro.live/how-it-works: questions, contract, planned features ## Contract - PadroLaunchLedger: 0x98b002783afb903a6d07b6945dc511941fc6b80e - publish(string name, string ticker, address token, string document) -> id; update(uint256 id, ...) publisher only; flag(uint256 id, uint8 reason) once per wallet - hash = keccak256(document bytes); document = canonical JSON (sorted keys, no spaces, ASCII with \u escapes), at most 8192 bytes ## Token - $PADRO: not launched yet.
