Launch B20 tokens across two chains.
Deploy a clean, admin-less token from the web or the CLI, native B20, or a fair bonding curve on Robinhood Chain.
A live look at a launch from the CLI.
What you get
Built to pass every check.
Native B20
Minted by the Base Beryl 0xB20f… precompile. Fully ERC-20 compatible, with roughly 50% cheaper transfers.
Admin-less and capped
Every launch ships with no admin: not mintable, not pausable, not freezable. Supply is capped and fully minted at birth.
Single-sided pool
The trading slice is seeded single-sided into a locked V4 pool. Instantly tradeable, liquidity locked forever.
Dynamic fee, 1 to 5%
The fee sits at your base rate and ramps toward your max only under volatility. Hard-capped at 5%, auditor-clean.
Fair vesting
Public launches vest 20% to the creator at 1% of supply per month over 20 months. No team bag dumped on day one.
No transfer tax
B20 is a clean ERC-20. The only fee is the swap fee, so buy/sell simulators pass and your token can be promoted.
Two chains, one launchpad
Pick where your token lives.
B20
Native B20The 0xB20f… precompile mints a native B20, admin-less, supply-capped, no transfer tax. Seeded single-sided into a locked Uniswap v4 pool, tradeable the moment it deploys.
Robinhood Chain
Bonding curveA fair bonding curve where price rises with every buy. When it hits the graduation cap, liquidity migrates to Uniswap v3. Contracts verified on Blockscout.

Beryl, your launch companion.
Two surfaces, one engine
Point and click, or type one command.
Configure your launch in a clean form with presets and live pricing, or run the CLI from your own terminal, non-custodial, with your own wallet. Both go through the same audited contracts.

What is B20?
B20 is Base's native token standard, shipped in the Beryl upgrade. Token logic runs in the node as a Rust precompile, full ERC-20 compatibility at a lower cost and higher throughput.
