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.

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.
