EVM-UI – visual tool to interact with EVM-based smart contracts

Hey HN!

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.
