Shardeum, the pioneering autoscaling Layer 1 blockchain, today announced the launch of its highly anticipated Mainnet. This landmark event follows an exceptionally successful testnet phase, which saw engagement from over 1.4 million global participants and an industry-leading 171,000+ physically run validator nodes—the highest recorded for a Layer 1 testnet. This mainnet launch signifies a major technical leap, transitioning Shardeum from years of intensive research and development into a fully operational Layer 1 network. It marks a critical step in the network's mission to conquer the Blockchain Trilemma, offering users and developers a harmonious blend of decentralization, scalability, and affordability without compromise.
"We’ve built Shardeum with the conviction that the future of Web3 must be open, inclusive, and truly scalable," said Srini Parthasarathy, Chief Technology Officer. "Mainnet is not just a technical milestone; it demonstrates that the blockchain trilemma—once seen as an inherent trade-off—is genuinely solvable. Our community’s unprecedented validator participation is clear proof of our commitment, achieved by ensuring that running a node is accessible and straightforward for anyone."
The Shardeum Mainnet debuts with a suite of powerful features, alongside its Token Generation Event (TGE). The network's foundation is its unprecedented validator participation, evidenced by over 171,000 validators on its L1 record-breaking testnet, with the Mainnet genesis commencing with 256 validators across 2 shards. A key aspect is the effortless node setup, allowing anyone to launch a node in under one minute via a single command, without requiring heavy hardware or a large stake, thereby fostering broad community participation. True autoscaling is a core tenet from inception; transaction capacity dynamically increases as more validators join, while gas fees are designed to remain consistently as low as $0.01, even during network congestion. This infinite scalability potential is achieved through dynamic state sharding and the proprietary Proof-of-Quorum Optimistic (PoQo) consensus. Post-launch, Shardeum will introduce an innovative validator accountability system featuring automatic rotation of underperforming nodes, moving beyond traditional slashing penalties. Underscoring its commitment to transparency, Shardeum launches with over 60 open-source repositories and more than 32,000 stars on GitHub. Furthermore, the network offers a seamless EVM-compatible and developer-focused environment, with full support for popular explorer tools and straightforward integration with major EVM-compatible wallets, including MetaMask.
Adam Struck, Managing Partner at Struck Crypto, commented, "Shardeum is proving that scale, security, and true community ownership can co-exist on a single Layer 1. They are building an autoscaling network where anyone can help secure it in under a minute. Launching mainnet with a record-size grassroots validator set is precisely the kind of milestone that convinces us Shardeum will be the foundation for the next wave of Web3 applications."
Shardeum launches with robust support from key ecosystem partners, including PrimeVault for secure treasury operations, Mintair for validator and operator services, and Tokensoft for airdrop and token vesting management. The project is backed by a formidable roster of prominent investors, such as Struck Crypto, Amber Group, Big Brain Holdings, Foresight Ventures, Arrington Capital, Jsquare/DFG, Axelar Foundation, The Spartan Group, Ghaf Capital, Jane Street, Alphemy Capital, Balaji Srinivasan, CoinGecko, and others, reinforcing its industry credibility and market readiness. The initial circulating supply of Shardeum's native token, SHM, will be 249 million at launch, with the Token Generation Event and subsequent listings coinciding closely with the Mainnet deployment.
Looking ahead, Shardeum anticipates developers will begin testing smart-contract functionality in the latter half of the year, with stable dApp deployments expected shortly thereafter. Global community events and meetups are planned to celebrate this momentous launch and showcase Shardeum’s vibrant, decentralized community. A transparent, phased roadmap will guide future network upgrades, including comprehensive smart-contract capabilities, ensuring the blockchain evolves with community feedback at its core.
With its Mainnet now live, Shardeum transitions from a visionary concept to a tangible reality, empowering developers, validators, and users worldwide to participate in a truly live, permissionless, and user-friendly blockchain ecosystem.
