Cosmos ecosystem protocol Neutron will enter long-term maintenance mode on March 17, with its DEX and Supervault products halting normal operations and switching to withdraw-only mode by April 17, BlockBeats reports. dNTRN holders can convert their tokens to NTRN from March 23 via the Drop website or the Neutron app, while wstETH holders must bridge their assets back to Ethereum by June 30. Hadron Labs will maintain the network until June 30, 2026, after which a manual withdrawal guide will be released, and Neutron governance will migrate from its current custom setup to the standard Cosmos staking model with dynamically adjusted inflation and a reduced validator set.

Neutron blockchain has entered long-term maintenance mode due to deteriorating market conditions and the absence of a viable development path or buyer, the project announced. Hadron Labs will maintain the network until June 30, 2026, after which continued operation will depend on community support, while Fireblocks will end its support for Neutron in April 2026. The project halted new deposits to Supervaults and DEXs on March 16 and will fully suspend them by April 17, will open dNTRN redemptions on March 23, and requires wstETH holders to bridge their assets back to Ethereum by June 30, with NTRN redemption details to be disclosed separately. Neutron's governance and tokenomics will be streamlined to align with the standard Cosmos chain framework, and any remaining assets after the foundation's liquidation will be returned to the DAO.

Neutron will transition governance, staking, and validator systems to the standard Cosmos model, adjust token inflation with the foundation and DAO planning to burn a significant amount of NTRN, and later introduce an NTRN redemption mechanism with remaining assets distributed proportionally to the DAO. Hadron Labs will maintain the network until June 30 before transitioning to a community-supported setup, Fireblocks support will end by the end of April, and the team said unfavorable market conditions and the absence of a viable long-term strategy prompted the decision after four years of development.
