eventtrader-launchpad

Single-file Python SDK for the EventTrader non-custodial token launchpad:

• Circle Arc (chain 5042 mainnet, 5042002 testnet) — $0 creation, zero platform fees, 100% of the locked-liquidity fees to the creator forever, gas paid in USDC. https://cymetica.com/launchpad/arc
• Robinhood Chain (chain 4663) — $0 creation, 0.25% curve fee with 80% to the creator forever. https://cymetica.com/launchpad/robinhood

Non-custodial: every write is an unsigned transaction the SDK fetches for you. You sign and broadcast it with your own wallet. No key ever reaches EventTrader. Reads need no API key and no login.

pip install eventtrader-launchpad          # + `pip install web3` only for sign_and_send

from eventtrader_launchpad import EventTraderLaunchpad

lp = EventTraderLaunchpad()
cfg = lp.config()                                        # live chains, factories, fees
hot = lp.list_tokens(sort="volume", limit=5, chain_id=5042)
q = lp.trade_quote(hot[0]["address"], side="buy", amount=1.0)

prep = lp.prepare_launch("My Token", "MYT", description="…",
                         website="https://example.com", chain_id=5042)  # Arc mainnet
tx = prep["unsigned_transaction"]        # {chain_id, to, value_wei, data, gas_hint}
# sign + broadcast `tx` with your own wallet, or:
# receipt = lp.sign_and_send(tx, private_key=os.environ["MY_KEY"])
