FAQ

General

What is ChainPortal?

ChainPortal is a no-code platform for creating and managing tokens, NFTs, and multi-token collections, built for 6 blockchain ecosystems (EVM, Solana, Cosmos, Aptos, SUI, NEAR). The networks enabled in the app today are 10 testnets across EVM, Solana, Aptos and NEAR; no mainnet is enabled yet.

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 the complete list. Enabled in the app today: Sepolia, Arbitrum Sepolia, Base Sepolia, Optimism Sepolia and Arc Testnet (EVM); Solana Devnet and Testnet; Aptos Testnet and Devnet; and NEAR Testnet. These are all testnets — no mainnet is enabled yet. Cosmos and SUI networks, and many more EVM chains, are configured but not yet enabled.

Costs & Fees

How much does it cost to create a token?

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 are built on OpenZeppelin's battle-tested libraries, and EVM contracts use the EIP-1167 minimal proxy pattern. A formal third-party audit is pending before mainnet; interim internal security-review 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.

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?

1. Go to the Faucets page in ChainPortal
2. Select your testnet
3. Click the faucet link
4. Enter your wallet address
5. Receive free test tokens (usually within 30 seconds)

Recommended testnets for beginners

• Sepolia (EVM) -- Most reliable faucet
• Solana Devnet -- Instant, reliable
• Base Sepolia (EVM) -- Low gas, fast

Troubleshooting

Transaction failed -- what do I do?

1. Check the error message in your wallet
2. Ensure you have enough gas (native tokens)
3. Try increasing gas limit by 20%
4. Check if the network is congested
5. If the issue persists, try on a different network

Wallet not connecting

1. Ensure the browser extension is installed and enabled
2. Refresh the page
3. Try disconnecting and reconnecting
4. Clear browser cache and cookies
5. Try a different browser

Token not showing in wallet

1. Copy the contract address from ChainPortal
2. In your wallet, click "Import Token" or "Add Token"
3. Paste the contract address
4. 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.
