Who We Are

Bloctopus is rebuilding Web3’s broken developer stack with testnets on demand. Public testnets are congested, inconsistent with mainnet, and lack privacy, forcing teams to do manual local setups or deploy straight to mainnet. Bloctopus spins up realistic, reproducible, customizable, interoperable, and enterprise-grade dev environments in seconds. We leverage Kurtosis, an open-source orchestration engine is already trusted by Ethereum, Polygon, Optimism, EigenLayer, & more. Teams can safely test token flows, staking, compliance, CI/CD loops and cross-chain deployments. We're building a decentralized Firebase for Web3.

LZero is founded by Anisha Goel and Til Jordan, repeat entrepreneurs with deep blockchain and fintech expertise. We started as a research initiative under the Ethereum Foundation. We have raised our seed round, backed by Techstars, Hivemind Capital, IronKey Capital, and Founders of Brevan Howard, Quantstamp, Cred Protocol amongst others. We're scaling fast, and we need you to help us build the future of blockchain infrastructure.
