Flap

🦋 Brief Overview of Flap

Flap is an on-chain token launch protocol on EVM, born out of an ETHGlobal hackathon victory. Flap's mission is to empower projects and creators with decentralized, on-chain tools to launch tokens and design customized token standards seamlessly.

Flap has two independent launch protocols:

  • Bonding curve launch: a token starts on Flap's bonding curve and migrates to a DEX once enough of its supply is sold.
  • Pool Launch: a token goes straight into a DEX pool in one transaction, with no bonding-curve phase.

Both support tax tokens and Flap Tax Vaults.

Rich Terminal & Wallets Support

Tokens launched via Flap are supported by a broad ecosystem of wallets, trading platforms, and bots, including OKX Wallet, Binance Wallet, GMGN, Debot, Ave.ai, Dragun, Axiom and more—ensuring strong discoverability and liquidity from day one.

Non-Tax & Tax Token Support

Flap supports both non-tax tokens and tax tokens. For tax tokens, creators can customize trading tax fee rates at 1%, 3%, 5%, or 10%, enabling flexible use cases such as community incentives, marketing, treasury funding, or charitable contributions.

Flap Tax Vaults

The main goal of a Flap Tax Vault is to customize how a tax token's tax revenue is distributed. Instead of sending the tax to a wallet, the token sends it to a vault: a smart contract whose code decides what happens to the revenue. A vault can split it between recipients, buy back and burn, pay holders dividends, reward stakers, fund a game, or run any other rule its developer writes. Because the rules are on-chain, holders can check where the tax goes.

By following the vault specification, a vault also gets its details and UI shown on the Flap website and supported terminals. Developers can publish their own vault templates (Vault Factories), and earn from them when creators launch tokens with their template.

Flap Pool Launch

Pool Launch is a second, independent launch protocol. It bypasses the bonding-curve phase: the token is created and its liquidity is added directly to a DEX pool in a single transaction. The LP is burned, so the pool cannot be pulled, and the token trades on the DEX from the first block.

The creator chooses the token supply and how much of it goes into the pool. The part that is not put into the pool can be reserved for a Pool Launch Vault. On top of distributing tax revenue, the vault can then run mechanisms that need a token reserve, such as mining or staking rewards, airdrops, vesting, or releasing tokens as the market cap grows. The reserve is held by the vault under rules written in its code, not in a wallet that could dump it.

Developers can also build their own launch page with a custom fund-raising logic, for example a presale, a mint or a game. Funds are raised before the launch, then used to add the token's liquidity to the pool when the conditions are met.
