review prepare

Review all your settings and prepare the transaction calldata.

What Happens When You Prepare

Clicking Prepare Launch triggers several operations:

1. Metadata Upload — your token name, symbol, description, and image are uploaded to IPFS via the Flap API

2. Salt Finding — a CREATE2 vanity salt is computed that gives your token a vanity address ending in 7777 (tax) or 8888 (standard)

3. Collision Check — the predicted address is verified on-chain to ensure no token already exists there

4. Calldata Building — deploy transaction calldata is built for Portal or VaultPortal

5. Buy Calldata — each wallet gets unique swapExactInput calldata with its BNB amount

6. Cost Simulation — estimated total BNB requirement including gas

Review Checklist

Before preparing, verify:

• Token name and symbol are correct

• Tax rate and distribution look right

• Vault configuration (if any) is correct

• All wallets have sufficient BNB (green checkmarks)

• Buy amounts are what you intended

• You're on the correct network (testnet vs mainnet)

Cannot be changed after deploy. Token name, symbol, tax rate, and vault configuration are immutable once the token is deployed on-chain.

Predicted Token Address

After preparation, you'll see the predicted token address. This is the CREATE2 address where your token will be deployed. It ends in:

• ...7777 for tax tokens

• ...8888 for standard tokens

Contract Routing

The Review step also shows which contracts will be used:

Configuration	Deploy Via	Buy Via
Standard token	Portal	Portal
Tax token (no vault)	Portal	Portal
Tax token (with vault)	VaultPortal	Portal

Buy and sell always go through the Portal's swapExactInput regardless of how the token was deployed.

Next Step

Click Prepare Launch, wait for the preparation to complete, then proceed to Launch.
