B20 documentation
What B20 provides
A complete launch, discovery, trading and creator-revenue experience built around verifiable onchain state.
Create
Deploy a 1B-supply token through a Bond or Direct DEX route, with metadata and an optional creator first buy.
Explore
Discover newest, bonding, graduated and direct markets across every supported network.
Trade
Buy and sell from the token page with quotes, minimum received, slippage controls and onchain activity.
Dashboard
Track created tokens, held assets, trading activity and claimable creator revenue from one wallet view.
Locked liquidity
Production LP positions remain in protocol custody without a principal-withdrawal or NFT-transfer path.
Historical continuity
Tokens created by legacy deployments remain indexed and continue to use the contracts they launched with.
BLUE staking
Stake BLUE on Base and receive a proportional share of native ETH protocol revenue.
Networks and token standards
The product experience is shared while each network uses its native launch standard and canonical DEX deployment.
Launches use the Base-native B20 ASSET standard. BLUE also lives on Base.
Launches use fixed-supply ERC-20 tokens and the network's official Uniswap v4 stack.
Bond and Direct launches use fixed-supply ERC-20 tokens. Launches, trades and gas are paid in MON.
Direct-only launches use fixed-supply ERC-20 tokens and canonical Uniswap v3. Launches, trades and gas use USDT0.
Direct-only launches use fixed-supply ERC-20 tokens and permanently locked Uniswap v3 liquidity. Launches, trades and gas use USDC.
Choose how price discovery begins
Both routes create a 1B-supply token with zero free creator allocation, but liquidity begins differently.
Price discovery before DEX graduation
- 01
The full supply enters the protocol bonding-curve market.
- 02
Users trade against virtual reserves until the fixed 5 ETH gross target is reached.
- 03
Remaining tokens and real ETH reserves graduate into a locked Uniswap v4 position.
- Optional first buy
- Up to 5 ETH
- Creator allocation
- 0%
- Graduation
- 5 ETH gross
Direct DEXA live Uniswap v4 market in one launch transaction
- 01
The token and concentrated-liquidity pool are created atomically.
- 02
The 1B supply starts as token-only, permanently locked liquidity.
- 03
Early buys add native ETH depth and move price along the configured curve.
- Optional first buy
- Max 5% supply
- Creator allocation
- 0%
- Graduation
- Not required
One fee policy across both launch routes
vNext Bond, Direct DEX and graduated pools use the same bounded onchain fee policy.
Routed to treasury. An optional creator first buy is added on top.
0.7% platform and 0.3% creator, both accounted in ETH.
0.7% platform in ETH and 0.3% of token input sent to the dead address.
Trade platform revenue is split automatically between BLUE staking and treasury.
Platform MON revenue accrues to the B20 Safe treasury; no implicit bridge or Base staking allocation exists.
Buy LP fees split 0.7% to the Safe and 0.3% to the creator. Sell LP fees split 0.7% token to the Safe and 0.3% token to burn.
| Event | Platform | Creator | Token burn |
|---|---|---|---|
| Bond buy | 0.7% ETH | 0.3% ETH | — |
| Bond sell | 0.7% ETH | — | 0.3% token input |
| Bond after graduation | 0.7% ETH | 0.3% ETH on buys | 0.3% token input on sells |
| Direct buy | 0.7% ETH | 0.3% ETH | — |
| Direct sell | 0.7% native output | — | 0.3% token input |
Permanently locked principal
vNext uses a zero-LP-fee hook, so principal stays locked while trade fees route independently.
No principal-withdrawal function is exposed by the production lockers.
No LP NFT transfer function is exposed to the creator or platform.
The unified hook overrides the LP fee to zero, preventing duplicate trade fees.
Creator ETH is pull-based; each creator can claim only its own recorded buy revenue.
Pool-to-token-to-creator registration is one-time and restricted to the permanent Bond and Direct lockers. Exact-output swaps are rejected; the supported trading path is exact input.
From launch to lifetime tracking
Creators keep control of their wallet while B20 organizes the onchain and indexed data around it.
Select a supported network and connect the wallet that will own the launch identity.
Add token identity, choose a launch route and optionally execute the creator first buy atomically.
View created tokens, holdings, trades and creator-fee balances in the dashboard.
Claim vNext buy-side creator ETH. Historical tokens keep the claim rules of the contracts they originally launched through.
Old tokens remain tradable
A new deployment changes future launches; it does not migrate or rewrite tokens that already exist.
The web app and indexers retain every supported Base and Robinhood deployment generation.
Each token is resolved by chain, deployment scope, launch mode and original contract addresses.
Bonding tokens continue through their original market; graduated and Direct tokens continue through their original Uniswap v4 pool.
Legacy tokens keep their original fee, creator-revenue, burn and LP-fee behavior and are never presented as vNext tokens.
Trading and approvals
Quotes and transactions use the route associated with the token's original launch.
Bonding phase
Buys and sells execute against the B20 bonding-curve market. Trading closes when graduation is ready, then moves to the locked Uniswap v4 pool.
DEX phase
Graduated and Direct tokens trade through their Uniswap v4 pool. Custom-hook pools may not appear immediately in every third-party aggregator even when B20 routing works.
Allowance reuse
A sell requires token allowance for the relevant spender. If the existing allowance is sufficient, B20 reuses it; otherwise approval and swap remain two separate wallet transactions.
Execution protection
The interface shows quotes and minimum received. Contract calls enforce deadlines, minimum output and the launch configuration hash where applicable.

BLUE is a community and platform identity asset. Staking rewards are variable and exist only when protocol revenue is deposited; no fixed return or price appreciation is promised.
BLUE staking
A Base-only, non-custodial staking vault distributes deposited protocol revenue in proportion to each wallet's active BLUE stake.
The router sends half of vNext trade platform revenue to staking. Launch fees currently remain 100% treasury.
Native ETH rewards stream over seven days instead of arriving in one block.
Additional requests aggregate and reset the timer; partial cancel and withdrawal are supported.
Share, treasury, operator and duration changes require a public timelocked transaction.
Administration cannot withdraw active or cooling user stakes and cannot seize accounted ETH rewards.
Claims and matured withdrawals remain available while new deposits or reward funding are paused.
An irreversible emergency mode removes cooldown waiting without transferring user funds to administration.
Owner, guardian and delay configuration can migrate to future multisig governance through delayed, onchain actions.
Current production contracts
Base, Robinhood and Monad vNext are deployed and live-smoke tested. Historical launches stay connected to their original contracts.
0x820344…e6b3450x7d42dd…e03a380x484345…fb1de80x394c5D…5891570x857f7D…7dabd70xf0b8dd…4c60cc0xe5c558…7a4941Security model and known constraints
Locked liquidity reduces one class of risk; it does not make a token valuable or eliminate smart-contract, market and infrastructure risk.
Delayed governance
vNext fee and future-launch settings are behind a seven-day, two-key timelock with rotatable owner and guardian roles.
Immutable pool identity
The unified hook accepts pool registration only from its frozen locker allowlist and never permits a registered creator mapping to change.
Burn accounting
vNext Bond, Direct and graduated-pool sell-token fees are sent to 0x0000…dEaD. Burn and platform revenue are emitted and readable onchain.
Market risk
Low liquidity, volatility, price impact, failed routing, RPC outages and irreversible transactions remain possible.
