This guide provides an overview of the various Metis networks along with their public RPC endpoints, making it easy for you to connect and start building
NOTICE: Metis is a native token but also an ERC20 compatible token on Layer 2. It is a built-in feature, so there is no need to create a wrapped Metis token, and the source code is here. Sushiswap team deployed a wMetis, it's the same with WETH9, the contract address is 0x75cb093E4D61d2A2e65D8e0BBb01DE8d89b53481
In case when you need higher limits of the public RPC endpoint, there are two options: 1. Setting up a private RPC endpoint using a provider such as Nodies or BlastAPI 2. Setting up a replica node

Oracles bridge the gap between blockchain systems and the external world, enabling smart contracts to interact with off-chain data sources. By connecting blockchains to external systems, oracles provide the crucial capability for smart contracts to execute based on real-world inputs, such as market prices, weather data, or random number generation.
Metis is integrated with leading Oracle providers to ensure developers have reliable and secure access to external data. Below is an overview of the Oracle providers supported within the Metis ecosystem:
Data Accessibility: Fetch and use off-chain data for your on-chain applications (e.g., asset prices, weather conditions, random numbers).
Decentralization: Ensures that data sources and their delivery are decentralized to avoid single points of failure.
Automation: Enable dynamic execution of smart contracts based on real-time data feeds.
Metis partners with several Oracle providers, each bringing unique strengths and capabilities to the platform. These providers integrate seamlessly with the Metis Layer 2 ecosystem:
1. DIA
Description: DIA (Decentralized Information Asset) is an open-source Oracle platform providing transparent and tamper-proof data feeds.
Use Cases: Ideal for decentralized finance (DeFi) applications, including price feeds and financial market data.
Documentation: DIA Integration Guide
2. Witnet
Description: Witnet is a decentralized Oracle network specializing in delivering trustless, tamper-proof data feeds.
Use Cases: Particularly suitable for prediction markets, insurance, and dynamic NFTs.
Documentation: Witnet Documentation
3. API3 QRNG
Description: API3 enables developers to access real-world data directly through first-party oracles.
Use Cases: Essential for gaming, lotteries, and other applications requiring randomness.
Documentation: API3 Guide
4. Chainlink
Description: Chainlink is the most widely used decentralized Oracle network, providing robust and reliable data feeds for blockchain ecosystems.
Use Cases: Supports a wide range of dApps, including price oracles, event data, and IoT integration.

Welcome to the Metis developer tools!
Welcome to the Metis developer tools! If you're already familiar with building on the Metis Layer 2 platform and need the right tools to begin developing, you're in the right place
Faucets are essential tools for developers that allow you to receive free Metis on Metis test networks like Sepolia. These tokens enable you to send transactions, test smart contracts, and build decentralized applications in a risk-free environment.
Below, you'll find a list of active faucets you can use to acquire test tokens for Metis networks. Since faucets may vary in how they authenticate users, you might need to try a few to find the best one for your needs. Faucets may also run out of tokens from time to time, so if one is not working, try another from the list.
Note: Testnet tokens are only meant for testing purposes and hold no real value. Make sure to request only what you need to help keep the faucet available for others.
