Welcome, fellow miner!
This is a Sepolia testnet on-chain playground. ⛏️
⛏️ Early Sepolia Mining (2021-2022)
When Sepolia testnet launched in October 2021 as a Proof-of-Work network, a few of us built mining rigs to support the testnet before it transitioned to Proof-of-Stake in July 2022 (following Ethereum's mainnet merge in September 2022).
🎮 The Creco Connection

We also joined creco.xyz and their mining game – a P2P platform that combined blockchain mining with actual gameplay mechanics. The pilgrim emoji and gaming approach comes from that experience.
Their Crecodiles NFT collection featured amazing on-chain art – 8,888 crocodile NFTs with DNA fully stored on Ethereum. Great and fun art! 🐊
Result: This testnet tool combines the best of both – Sepolia testnet functionality with the fun gaming mechanics we enjoyed at creco.xyz.
🏴☠️ What You're Looking At

We had an idea about playing on a blockchain to track transactions as part of the gameplay itself. That's exactly what this does – but with our pooled testnet Sepolia ETH, making it free and fun for everyone!

We've made it super easy to get started! When you create a treasure chest, we auto-generate
a random 7-character name for you (like a7f3e2d
).
You can use it as-is for instant mining, or change it to something personal like "alice" or "main".
💡 Auto-generated names use secure random hashing - just like your wallet keys!
