Connect and fund your deployer wallet (who pays gas at each step)
Updated Jun 21, 2026, 09:46 AM
You deploy every Saleium product from your own connected wallet, so that wallet needs enough native gas token on the chain you pick, and you (the operator) pay network gas to deploy and to send airdrops, while participants pay their own gas when they claim or interact on chain.
Who this is for: Operators who are deploying Token Sale, Staking, Vesting, or Airdrop products on Saleium, plus a short note for participants who later claim.
How do I connect my deployer wallet?
Saleium is non-custodial. You deploy your own smart contracts from your own wallet and you own them. Saleium never takes custody on the self-serve route.
- Open the dashboard at https://saleium.io and connect your wallet.
- Pick the chain you want to deploy on. The live chains appear in the in-app chain selector. As of this writing that list includes BNB Chain, Polygon, Base, Arbitrum, and Avalanche, but always check the in-app chain selector for the current live list rather than relying on memory.
- Make sure your wallet is on that same network before you start the wizard.
The wallet you connect becomes the deployer and the owner of the contract you create, so connect the wallet you actually want to control the product.
Which token do I need for gas, and how much?
You need the native gas token of the chain you chose, held in your connected wallet. For example, BNB on BNB Chain, MATIC/POL on Polygon, ETH on Base and Arbitrum, and AVAX on Avalanche. The exact amount depends on current network conditions, so fund the wallet with a comfortable buffer before deploying. UNKNOWN exact gas cost per deploy, this varies by chain and network load.
If you do not have enough native gas, the deploy transaction will not go through.
Who pays gas at each step?
- Deploy. You, the operator, pay network gas from your connected wallet when you deploy any product. The deploy flow moves through phases (drafting, then deploying, then recording, then done) and finishes with a "Deployed" card showing your new contract address and next steps.
- Airdrop send. You, the operator, pay network gas to send an airdrop. Airdrops have no Saleium platform fee, you pay only network gas.
- Claims and on-chain interactions. Participants pay their own network gas when they claim tokens or otherwise interact with your contract on chain.
What about the platform fee versus gas?
Network gas and the Saleium platform fee are two separate things.
- Gas is paid to the blockchain network, not to Saleium, by whoever sends the transaction (see who-pays above).
- The platform fee is a percentage Saleium charges per product, and it is stamped immutably into your contract at deploy. The platform can never raise it later, and your plan can only lower it. Concrete defaults by product:
- Token Sale: 15% of a successful raise, paid by the project from the raised funds when you withdraw. It does not reduce a contributor's token allocation. A project may add its own markup of up to 10% on top, which the project keeps, so a contributor can see up to about 25% taken from the raise at the maximum markup. If a sale fails or times out, the contributor pays a 5% refund fee, deducted from their refund.
- Staking: 5% of rewards, taken from reward payouts. Plans lower it to 4.75% (Growth), 4.5% (Pro), and 3.75% (Business).
- Vesting: 1% of the tokens, taken when the project funds the vesting pool, charged on each funding. The beneficiary also pays a small per-claim fee in the network's gas token, about $1 worth or the claim's gas cost, whichever is higher.
- Airdrop: no platform fee at all, only network gas.
A higher plan discounts your platform fees (Growth 5%, Pro 10%, Business 25% off; Free 0%). The Plans & Billing page shows the exact rate that applies to your plan, so check there for your exact number.
Airdrops carry no platform fee at all, only network gas.
Common issues
- Deploy fails or never confirms. Confirm your wallet holds enough of the chosen chain's native gas token, and that your wallet is connected to the same network you selected in the chain selector.
- Wrong network. If your wallet is on a different network than the one you picked, switch your wallet to the selected chain before deploying.
- Want a managed deploy instead of self-serve. The self-serve route is the non-custodial path where you hold the keys and pay gas. For a managed route or Mirror Mode, contact the ChainGPT team rather than looking for a self-serve toggle.
- Gas estimate looks high. Gas is set by the network, not by Saleium. Fund a buffer and, where possible, deploy when the network is less congested.
