What is the Optimism Sepolia Testnet Faucet?

The Optimism Sepolia Faucet is a tool designed to provide users with a quantity of tokens for experimentation and testing on the Optimism Sepolia Testnet. The tokens can be claimed once every 24 hours. Additionally, for an extra allocation, users can share a tweet using the provided template.

What is the Optimism Sepolia Testnet?

Optimism Sepolia provides a secure testnet space for developers to experiment and test smart contracts using Optimism Sepolia ETH. This not only streamlines the development journey but also minimizes the financial risks associated with deploying contracts on the Optimism mainnet. The protocol's core objective is to augment affordability and efficiency in transactions, achieved by processing them in batches through optimistic rollups. By aligning with the Ethereum consensus, Optimism ensures seamless integration while providing substantial reductions in gas fees and faster transaction times, benefiting both developers and users.

What are testnet tokens?

Testnet tokens are virtual tokens that are used on testnets, which are experimental blockchain networks. Testnet tokens allow developers to test new features and functionality before deploying them to the main blockchain. These tokens have no real-world value and cannot be used on the main blockchain.

How does this work on Blast?

Blast provides infrastructure support and development tools for a diverse range of over 60 blockchain networks. To facilitate seamless testing and development workflows, we have established strategic partnerships with key blockchain networks, enabling developers to receive a daily allocation of tokens for testing purposes. Find out more about Blast!

What is the daily total allocation?

The daily total allocation serves as a limit on the number of tokens that can be claimed by all users within a 24-hour period, and once that limit is reached, the faucet will stop dripping tokens. If the daily total allocation is filled, users will not be able to claim additional Optimism Sepolia ETH tokens until the next 24-hour cycle begins.

Why is the faucet not working?

The faucet might not be available temporarily, either due to maintenance work or lack of funds. If you checked and your wallet address is correct, please try again later. If the problem persists, contact us on Discord or through the Contact form.
