Exploring Citrea Testnet with Leap Wallet

The ₿app Layer, Citrea Testnet, is live on Leap. Experience native DeFi & bridging on Bitcoin, Citrea is building a zero-knowledge rollup that settles directly on Bitcoin. This is significant because it brings smart contract functionality and scalability to the Bitcoin ecosystem without compromising security.

Why Citrea Matters Now:

  • Bitcoin's First ZK Rollup: Citrea is pioneering ZK rollup technology on Bitcoin, potentially revolutionizing Bitcoin's utility beyond just a store of value

  • Substantial Backing: The project has raised an impressive $16.7 million in funding, indicating strong investor confidence

FAQs


What is a ZK rollup on Bitcoin?

A ZK (Zero-Knowledge) rollup is a scaling solution that bundles multiple transactions together off-chain and generates cryptographic proof of their validity. Citrea is implementing this technology on Bitcoin to improve transaction throughput while maintaining security.


Do I need real Bitcoin to participate?

No, you don't need real Bitcoin. This is a testnet campaign that uses test tokens which have no real value. You can get these tokens for free from the Citrea faucet.


How will I know if I qualify for future rewards?

Typically, projects track participation through wallet addresses. By completing all tasks and minting the badge, your wallet address will be recorded as having participated in the testnet.


What wallet should I use for the Citrea testnet?

Any Ethereum-compatible wallet that supports custom networks should work. Make sure to connect to the Citrea testnet network in your wallet settings.


Can I participate multiple times with different wallets?

While technically possible, most projects have measures to detect and disqualify multiple submissions from the same user. It's recommended to focus on completing all tasks thoroughly with one wallet.
