# B20 mode

> Launch a chain-native B20 token, permanently admin-less from its first block.

B20 is Base's chain-native token standard - the same standard Coinbase's
tokenized stocks use. BaseStonk can launch your token as a real B20
instead of a standard ERC-20.

## Admin-less is provable, not promised

A B20 launch:

1. Creates the token through **Base's B20 factory precompile**
2. Mints the fixed 1B supply
3. **Renounces both the mint role and the last admin inside the launch
   transaction**

From the moment it exists, nobody - not BaseStonk, not the creator - can
mint, pause or freeze it. The chain itself is the receipt: verify the
renounce in the launch transaction on Basescan.

## What B20 mode trades away

The standard has no holding caps and calls no external trackers, so B20
launches ship **without max wallet and without holder dividends**.

Everything that lives in the pool's hook rather than the token works
unchanged:

* Trade tax and fee splits
* Buyback & burn
* The unpullable single-sided pool

The toggle appears in the create form when you pick a B20 pair, and it
states both halves of this trade before you sign.
