## Launch fee

The launch fee is the Pons factory's own fee, currently **0.0005 ETH**, paid as part of the launch transaction. Sponsor passes it straight through and adds nothing at launch.

## Dev buy

An optional amount of ETH you spend buying your own coin inside the launch transaction. The tokens go directly to your wallet.

## Platform fee

Sponsor's platform fee is **20%** of collected fees. It is fixed for each coin when the coin launches, and the remainder goes to the directed profile's balance. Claiming itself is free apart from gas: the platform fee is already accounted for before fees reach your balance.

## Gas

You pay your own Robinhood Chain (chain id **4663**) gas for launching and claiming. Claims are cheap. The claim page suggests bridging when your wallet holds **0.0002 ETH** or less; routes are in [Robinhood's bridging guide](https://docs.robinhood.com/chain/bridging/).
