Shardeum Mainnet Goes Live, Debuting Autoscaling L1 After Record Testnet Validator Participation

The EVM-Compatible Blockchain continues on its mission to facilitate an affordable blockchain ecosystem with fees as low as $0.01.

Shardeum , the autoscaling Layer 1, today announces the launch of its long-anticipated Mainnet on May 5th, 2025. It follows a highly successful testnet phase that attracted over 1.4 million global participants, and over 171,000 physically run validator nodes – the highest among Layer 1 testnets.

The Mainnet launch marks the transition from an extended period of research and development to the deployment of a live Layer 1 network. This milestone is a major step forward in the network's mission to solve the blockchain trilemma, enabling global users and developers to experience decentralization, scalability, and affordability without trade-offs.

With Shardeum's Mainnet launch comes a myriad of features as well as its Token Generation Event (TGE).

Key Features at Launch

Permissionless Validator Network:

• 171,000+ validators on testnet (L1 record)
• Mainnet genesis starts with 256 validators (2 shards)
• Spin up a node in under one minute via a single-command install – no heavy hardware or large stake required, enabling widespread community participation

Autoscaling from Day 1:

• Transaction throughput automatically scales as validator participation grows
• Gas fees remain consistently as low as $0.01, even under network congestion
• Dynamic state sharding and proprietary Proof-of-Quorum Optimistic (PoQo) allowing the network to scale near-infinitely as more nodes join
• Post-launch: Innovative validator accountability system involving automatic rotation of consistently under-performing nodes (avoiding traditional slashing)

Open Source Development:

• Launching with 60+ open-source repositories and over 32,000 stars on GitHub, Shardeum's codebase is open and transparent

EVM-Compatible & Developer-Ready:

• At launch, Shardeum will support popular explorer tools with seamless integrations with major EVM-supporting wallets, including MetaMask

Backed by Ecosystem Partners

At launch, Shardeum will be supported by partners including PrimeVault (secure treasury operations), Mintair (validator and operator services), and Tokensoft (airdrop and token vesting management).

Shardeum is backed by prominent investors, including Struck Crypto, Amber Group, Big Brain Holdings, Foresight Ventures, Arrington Capital, Jsquare/DFG, Amber Group, Axelar Foundation, The Spartan Group, Ghaf Capital, Jane Street, Alphemy Capital, Balaji Srinivasan, CoinGecko, and others, further reinforcing its industry credibility and market readiness.

The total circulating supply of SHM at launch will be 249 million. Token generation and listings will align closely with the Mainnet rollout.

Next Steps Following Mainnet Deployment

In the latter half of the year, Shardeum expects that developers will be able to begin testing smart-contract functionality, with stable dApp deployments expected soon after.

Global community events and meetups are planned to celebrate this launch, showcasing Shardeum's vibrant decentralized community. Shardeum's transparent and phased roadmap clearly communicates future network upgrades, including comprehensive smart-contract capabilities, ensuring the blockchain evolves transparently with community feedback at its core.

With Mainnet live, Shardeum moves from vision to reality, empowering developers, validators, and users to finally participate in a live, permissionless, user-friendly blockchain environment.

About Shardeum

is an autoscaling EVM-based layer-1 blockchain. Dynamic state sharding helps keep gas fees low and TPS high as participation grows. Shardeum performs consensus at the transaction level and lowers the computational power needed for validator nodes. This consensus mechanism makes it possible for anyone to run a node while increasing decentralization.
