How Launch HUB works

Launch HUB launches one token on three chains at the same time: Solana through Pump.fun, BNB Chain through Flap.sh and Robinhood Chain through Pons. The three deployments are separate tokens on separate launchpads, and the Launch HUB bridge lets holders move balances between them.

   Fill in the details

   Logo, name, ticker, an optional description and links. The same details are used on every chain.
2. 2

   Fund three addresses

   Launch HUB creates three fresh deployer wallets for your launch and shows each address with the exact amount it needs. You send SOL, BNB and ETH to them from any wallet or exchange.
3. 3

   Deployment

   Once all three wallets are funded, the deployer wallets create the token on Pump.fun, Flap.sh and Pons.
4. 4

   Live

   The token appears on the board with its market cap per chain, contract addresses and charts.

Every launch gets its own set of three deployer wallets. They exist only for that launch: they receive the funding, pay the launchpad fees and gas, and make a small seed buy at launch (0.025 SOL, 0.0035 BNB, 0.001 ETH). Afterwards they collect the token's creator fees.

You send each amount yourself, from any wallet or exchange that can pay on that chain. The Launch page lists the three addresses with their amounts and updates as the funds arrive; nothing is signed in the app.

Each launchpad pays a share of trading fees to the token's creator. For a Launch HUB token the creator is the deployer wallet of that launch, and 100% of what it collects goes back into the token: 80% buys the token on that chain and moves it into the bridge reserve, 20% funds the bridge. Nothing is paid out to Launch HUB or to the person who launched the token.

The fee itself is the launchpad's own: Pump.fun's creator share, Pons' creator share plus a 1% creator tax, Flap's 1% buy and 1% sell tax. Claims run automatically once enough has accrued on a chain, and every claim and buyback is a public transaction from the deployer wallet. At launch, Launch HUB also makes one small seed buy per chain (0.001 ETH on Robinhood Chain and the same value on the others) to open the bridge reserve.

The bridge moves a token between its three deployments. You send tokens to the bridge on the source chain and the same amount is released to your address on the destination chain from Launch HUB's reserve there.

1. 1

   One transaction on the source chain

   On Solana a single transaction carries the token transfer to the vault, the fee in SOL and a memo naming the destination:

   Solana memo

   lh1|<destination chain>|<your receiving address>
   lh1|bnb|<your EVM address>
   lh1|solana|<your Solana address>

   On BNB Chain and Robinhood Chain it is an approve followed by one call on the bridge vault:

   EVM vault

   function deposit(
     address token,     // the token's contract on this chain
     uint256 amount,    // in the token's smallest unit
     uint8   dstChain,  // 0 = Solana, 2 = BNB, 1 = Robinhood
     bytes32 dstAddress // recipient, left-padded EVM address or Solana pubkey bytes
   ) external payable returns (uint256 nonce);
   // msg.value carries the $1 fee in the chain's native asset

2. 2

   Confirmation

   The bridge acts as soon as the source transaction is confirmed. If the destination reserve is short, the transfer waits up to 15 minutes for it; if the reserve is still short after that, your tokens are returned to the sending wallet on the source chain (the $1 network fee is not returned).
3. 3

   Release

   99% of the amount is sent to the destination address; 1% stays in the destination reserve. If the token trades more than 30% higher on the destination chain, the release is reduced so the transfer gains at most 30% in value; the form shows this before you send. Both transactions are linked from the Activity panel on the Bridge page.

The bridge is one contract per EVM chain and a vault wallet on Solana. Always check that the address you send to matches the ones below; Launch HUB never asks you to send tokens anywhere else.

• SolanaBridge vault
  8Td4WP6kapED1shHt9UXDyFBVpuszexosjF1UvCRP8vL

  Receives deposits; the memo names the destination.

• SolanaFee wallet
  8Td4WP6kapED1shHt9UXDyFBVpuszexosjF1UvCRP8vL

  Receives the flat fee in SOL.

• BNB ChainBridge contract
  0x3e55551e5336835cB48A575F0D0376563fbD574E

  LaunchHubBridge; deposit is payable with the fee in BNB.

• Robinhood ChainBridge contract
  0x3e55551e5336835cB48A575F0D0376563fbD574E

  LaunchHubBridge; deposit is payable with the fee in ETH.

• Launching

  Launchpad fees, gas and one small seed buy on each chain (0.025 SOL, 0.0035 BNB, 0.001 ETH).

• Bridging

  $1 per transfer in the source chain's native asset, plus 1% of the tokens moved.

• Price gap cap

  When the destination chain prices the token more than 30% above the source chain, the amount released is reduced so the transfer gains at most 30% in value. The difference stays in the destination reserve.

• Trading

  No Launch HUB fee. The launchpad's creator fee goes back into the token: 80% buybacks, 20% bridge.
