We've built https://evm-ui.com, a free tool that allows you to interact with smart contracts visually.
It started as an internal project while building Web3 apps for clients — we needed something more flexible and lightweight than Remix or Etherscan's UI.
Unlike Etherscan or Polygonscan, you don't need to verify and open-source your smart contract to get a working UI. Paste the ABI (or load it from a template) and proceed.
With EVM-UI, you can
- Import contracts by address + ABI, or paste ABIs directly
- Read/write functions with auto-generated UI (supports all Solidity types, including arrays)
- Execute actions with smart inputs (dropdowns, min/max helpers, etc.)
- Switch between EVM chains, testnets, or local RPCs within one workspace
- Use developer tools (Keccak256, ABI encoder/decoder, address utils)
- Share environments with your team and your client
We'd love to receive your feedback, ideas, or constructive criticism.
P.S. We're aware that signup emails may go to spam - fixing that now.
