FAQ
Frequently asked questions about ChainPortal -- costs, security, supported chains, troubleshooting, and more.
General
What is ChainPortal?
ChainPortal is a no-code platform for creating and managing tokens, NFTs, and multi-token collections across 6 blockchain ecosystems (EVM, Solana, Cosmos, Aptos, SUI, NEAR) and 50+ networks.
Do I need to know how to code?
No. ChainPortal handles all smart contract deployment through an intuitive UI. You just fill in the details and click create.
Is ChainPortal free?
ChainPortal charges a small protocol fee on token/NFT creation. You also pay blockchain gas fees (which go to the network, not ChainPortal). Testnet usage is completely free.
Which chains are supported?
See the Supported Chains page for a complete list. Currently 33+ EVM chains, Solana, Cosmos, Aptos, SUI, and NEAR.
Costs & Fees
How much does it cost to create a token?
| Network | Estimated Cost |
|---|---|
| Ethereum Mainnet | $5-50 (varies with gas) |
| Polygon/Arbitrum/Base | $0.01-1.00 |
| Solana | Under $0.01 |
| SUI | Under $0.01 |
| NEAR | $0.01-0.05 |
| Any Testnet | Free |
What is the protocol fee?
ChainPortal charges a small fee on each deployment. The exact fee varies by chain and asset type. Check the creation form for the current fee before deploying.
Can I reduce fees?
Yes -- use a referral code during creation to potentially get a discount. Or refer others to earn commissions.
Security
Are the smart contracts audited?
All contracts use OpenZeppelin's battle-tested libraries. EVM contracts use the EIP-1167 minimal proxy pattern. Security audit documentation is available in the repository.
Is my wallet safe?
ChainPortal never has access to your private keys or seed phrase. All transactions are signed in your wallet. We only request permission to send the specific transaction you initiated.
Never share your seed phrase. ChainPortal will never ask for it. If anyone — in our Discord, Telegram, or email — asks for your seed phrase, it is a scam.
Can ChainPortal take my tokens?
No. Once deployed, your tokens are on the blockchain. ChainPortal factory contracts do not have admin access to your deployed tokens unless you explicitly grant it.
IPFS and Metadata
Where are NFT images stored?
On IPFS (InterPlanetary File System) via Pinata. IPFS is a decentralized storage network -- your files are permanent and cannot be censored or deleted.
What file types are supported?
PNG, JPEG, GIF, WebP for images. JSON for metadata. Maximum 10MB per file. Files are validated server-side using magic-byte checking.
Faucets
How do I get testnet tokens?
- Go to the Faucets page in ChainPortal
- Select your testnet
- Click the faucet link
- Enter your wallet address
- Receive free test tokens (usually within 30 seconds)
Recommended testnets for beginners
- Sepolia (EVM) -- Most reliable faucet
- Solana Devnet -- Instant, reliable
- Polygon Amoy -- Low gas, fast
Troubleshooting
Transaction failed -- what do I do?
- Check the error message in your wallet
- Ensure you have enough gas (native tokens)
- Try increasing gas limit by 20%
- Check if the network is congested
- If the issue persists, try on a different network
Wallet not connecting
- Ensure the browser extension is installed and enabled
- Refresh the page
- Try disconnecting and reconnecting
- Clear browser cache and cookies
- Try a different browser
Token not showing in wallet
- Copy the contract address from ChainPortal
- In your wallet, click "Import Token" or "Add Token"
- Paste the contract address
- The name and symbol should auto-fill
I deployed on the wrong network
Unfortunately, blockchain transactions are irreversible. Deploy again on the correct network. On testnets this is free, on mainnets you will need to pay gas again.
