# EVMist
> The local-first operations workspace for EVM smart contracts.

EVMist allows developers, protocol operators, and power users to build reusable control panels and workspaces for any Ethereum-compatible smart contract. Instead of constantly repeating workflows on block explorers or clunky protocol UIs, users can build layouts to read data, monitor protocol states, and execute transactions from a unified browser interface.

## Key Concepts
- **Workspace over Dashboard:** EVMist is a technical workspace where contract execution happens, not just a passive viewer.
- **Local-First Architecture:** All configurations, layouts, and data points remain exclusively inside the user's browser storage. No private keys, trackers, or telemetry are sent to central servers.
- **Mental Models:** It functions effectively as a "Retool for smart contracts" or a "Grafana + Postman for EVM operations."

## Features

- Configure smart contracts with auto & manual ABI look-up
- Auto generate layouts filled with calls and sections from smart contracts
- Encode and share section configs, including prefilled arguments
- Re-create write call transactions from hash and chain ID
- Decode and re-use call data in transactions
- Configure EVM chains with RPCs, including a fallback
- Construct write calls with exposed pre-flight call data
- Create and manage layouts
- Choose a colour scheme from a variety of options
- Set an interval to refetch read calls
- Back-up and import your config
- Copy offset from Unix timestamp
- Submit errors and request features
- Force refetch calls
- Place drag & drop resizable widgets
- Chain calls together or bulk call against arrays of data
- All fully configured read calls in sections are collected, processed, and sent off in batches to a multicall3 contract
- Currently restricted to any EVM with a multicall3 deployment (self-deployable if unavailable)

All payments are peer-to-peer on-chain. EVMist does not custody funds. All sales are final; no automatic refunds.

## Privacy & Data

EVMist uses a **local-first architecture**. There is no central database for user data.

- **IndexedDB (via Dexie.js):** Stores dashboard configurations, cached network info, and layouts locally on the user's device.
- **LocalStorage:** Stores user preferences, session status, and application state locally.
- **No private keys or seed phrases** are ever accessed or stored.
- **No email addresses, IP addresses, browsing history, or personal identity** are collected.
- **To delete data:** Clear browser site data for evmist.io.
- **Export:** Users can back up configurations via the in-app export tool before clearing data.

### Third-Party Services

- **Hosting:** Krystal (UK). Standard server logs (IP, User-Agent) may be temporarily stored for security.
- **RPC Providers:** Users connect directly to RPC endpoints. EVMist cannot verify or guarantee the privacy practices of third-party RPCs.
- **Thirdweb:** Used for wallet connectivity; may process metadata (e.g., IP) to facilitate connections.
- **Blockchain:** All signed transactions are broadcast to public blockchains and are permanently visible.

## Terms of Service

- The service is provided "AS IS" and "AS AVAILABLE" without warranties.
- EVMist does not provide investment, financial, legal, or tax advice. All outputs are informational only.
- Users are solely responsible for their configurations, contract calls, arguments, and on-chain transactions.
- Simulation functions are estimates only and may not reflect actual on-chain behaviour.
- EVMist is not liable for losses arising from misconfiguration, malicious contracts, incorrect arguments, or reliance on displayed data.
- Governed by the laws of England and Wales.

## About

EVMist was built by Chris (Christopher Vickery), a self-taught TypeScript developer who built the tool after years of working in the Aavegotchi ecosystem (the perfect place to learn about complex smart contracts). EVMist was created to stay out of the user's way — giving a single place to curate EVM contract interactions and providing a powerful alternative to missing or restrictive protocol UIs.
