PANews reported on March 14 that according to Chainwire, Layer1 blockchain Shardeum is preparing for the launch of the mainnet and has launched a structured airdrop campaign for early contributors. A total of 5.5 million SHM tokens will be distributed to 63,000 eligible wallets. The airdrop is divided into two different phases, each targeting a different group of contributors: Phase 1 rewards users who participated in Liberty Alphanet and Sphinx Betanet between February 2022 and June 2024, with a snapshot taken on June 22, 2024, with a total allocation of 3.3 million SHM. Phase 2 is mainly aimed at those who participated in Shardeum's Atomium incentive testnet between June 2024 and March 2025, and a snapshot was taken on March 1, 2025, with a total allocation of 2.1 million SHM.

In addition, Layer1 blockchain Shardeum announced today on the X platform that the SHM token airdrop registration is now live. Eligible users who register within the first 7 days will receive the allocation at the TGE. The SHM airdrop registration ends at 07:59 Beijing time on April 14, 2025. According to its recently announced updated token economics , SHM's uses include staking functions, rewards, and gas functions. Its initial supply is 249 million, of which 36.72% is used for sales (after a 3-month lock-up period, daily linear unlocking within 2 years), 30.6% is allocated to the team (after a 3-month lock-up period, daily linear unlocking within 2 years), 22.44% is allocated to the foundation (unlocked at TGE), and 10.23% is allocated to the ecosystem and airdrop (unlocked at TGE). Similar to Ethereum, validator rewards will be dynamically generated based on network demand. Since all fees are 100% destroyed, SHM is expected to show a deflationary trend over time.
