# pons docs

> A concise guide to pons for users and builders.

## User guide
- pons is a noncustodial token launch and trading interface on Robinhood Chain.
- Tokens trade against WETH in live liquidity pools.

- Public launching is closed. Read canLaunch(address) on the factory before offering a create flow.
- Buys in the first 5 seconds of a launch pay a decaying snipe tax, starting at 99% and halving repeatedly to zero. Read currentSnipeTaxBps(recipient) on the curve before quoting a buy.
- The curve has no quote function. Price a trade off getReserves(), feeBps, creatorTaxBps, and sellableTokens(). Buy fees come off the input, sell fees come off the output. Formulas for both directions: https://docs.ponsfamily.com/v2#quoting
- These are the current stack. A token launched before it settles through the hook and escrow it was created against, so resolve a token's stack from the factory that launched it rather than assuming this one.
