Frequently Asked Questions
OnChainDeploy is a no-code platform that lets anyone deploy and verify smart contracts on Base Mainnet with a single click. You connect your wallet, pick a pre-tested contract template, and your contract goes live on the blockchain in seconds — no Solidity knowledge or development tools required.
No. OnChainDeploy is built specifically for non-developers. You do not need to know Solidity, use Remix, or set up any development environment. Every contract template is pre-written and tested. You simply choose one and deploy it from your browser.
Deploying a contract is completely free — you only pay the standard Base network gas fee, which is usually a fraction of a cent. The optional Deploy & Verify feature, which publishes your contract's source code to BaseScan, costs a flat $0.09 paid in ETH.
Yes. OnChainDeploy is non-custodial, meaning we never hold your funds, private keys, or control your contracts. You sign every transaction directly from your own wallet such as MetaMask or Rabby. The platform cannot move your funds or access your wallet.
Verification publishes your contract's source code publicly on BaseScan, the Base blockchain explorer. A verified contract is transparent and trusted — anyone can read its code and confirm what it does. This is important for credibility, especially if other people will interact with your contract.
OnChainDeploy supports MetaMask and Rabby wallets. You connect your wallet with one click and can disconnect at any time. No account or signup is needed.
OnChainDeploy deploys contracts to Base Mainnet, an Ethereum Layer 2 network built by Coinbase. Base offers very low gas fees and fast transactions, making it ideal for affordable contract deployment.
OnChainDeploy currently offers templates including GM Beacon, Simple Storage, Hello Base, Counter, Voting, Mood Tracker, Visitor Tracker, Chain Notes, and Lucky Block. More templates including ERC-20 tokens, NFT drops, and multi-sig wallets are coming soon.
Yes. Once a contract is deployed to Base Mainnet, it exists on the blockchain permanently and cannot be deleted or undone. Always review the details before confirming a deployment in your wallet.
Remix is a developer tool that requires you to write or paste Solidity code, compile it manually, and understand deployment parameters. OnChainDeploy removes all of that — there is no code, no compiling, and no configuration. It is designed for people who want results without the technical complexity.
