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.

1. 1

   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 the 3% buy at launch.

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.

Every token is created in the launchpad's holder rewards mode. The share of trading fees the launchpad would normally pay to the creator is paid out to token holders instead, by the launchpad itself, on each chain.

At launch, Launch HUB buys 3% of supply on each chain and keeps it. That balance backs the bridge and earns the same holder rewards as everyone else. This is Launch HUB's only income: there is no creator fee, no trading tax and no fee on this site.

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 and completes once the reserve is topped up.
3. 3

   Release

   The same amount is sent to the destination address. 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 the 3% buy on each chain.

• Bridging
