LayerZero cut 20 unused public chains in one go, and Stargate users must withdraw their assets before the deadline

20 low-activity public chains will gradually lose LayerZero’s DVN and Executor services, and Stargate v2 is also removing support for 5 of those chains at the same time. The first wave takes effect on July 30. If users do not redeem USDC.e, wETH, and USDT before the deadline, they will permanently lose fund access rights.

• 20 chains exit in four waves, with as little as 4 days left
• Users of five chains need to pay attention—asset redemptions have their own details
• Service removals don’t mean contracts disappear, but nobody will run verification for you
• Check the address first—don’t wait until the last day

The cross-chain infrastructure leader LayerZero announced in its official notice on July 24 that it will wind down off-chain service support for 20 chains. The Stargate v2 protocol deployed on those networks will also terminate support for 5 of those chains in parallel. The announcement states that if users do not take action before support for the chain is fully terminated, “it will lead to losing fund access rights,” and the earliest effective Botanix has less than a week of buffer left.

20 chains exit in four waves, with as little as 4 days left

According to the announcement’s table, LayerZero’s DVN (decentralized verification network) and executor services will exit in four waves based on the effective date:

• Takes effect July 30: Botanix
• Takes effect July 31: Moonriver, Moonbeam, Nexera, Canto
• Takes effect August 28: EDU Chain, Meter, Shimmer, Cyber, Silicon, Sophon, Bitlayer, DFK Chain, Arbitrum Nova, DOS Chain
• Takes effect September 30: Aurora, Taiko, BounceBit, Japan Open Chain, LightLink

In other words, the 20 chains listed above will no longer receive LayerZero’s official message verification and delivery services going forward. The same announcement also singled out that the Stargate v2 protocol will directly stop supporting 5 of those chains, with the effective dates aligned to off-chain services: Botanix (7/30), EDU Chain (8/28), Aurora (9/30), Taiko (9/30), LightLink (9/30).

Users of the five chains need to pay attention—asset redemptions have their own details

The announcement specifically added warnings for asset holders of certain chains:

• Botanix: Users holding USDC.e and WETH should first bridge funds to another chain that still supports Hydra, and then redeem via Stargate Pools to avoid assets getting stuck.
• EDU Chain: Users holding USDC.e should bridge funds back to Stargate Pools before the effective date.
• Aurora: Liquidity providers for the Stargate Pool (holding S*USDC) should withdraw funds from the USDC pool before the effective date.
• Taiko: Users holding USDC.e and Hydra USDT should bridge to Stargate Pools before the effective date.
• LightLink: Users holding Stargate Hydra USDC.e/USDT should bridge to Stargate Pools; ETH liquidity providers holding S*ETH should withdraw funds from the ETH pool.

LayerZero directly warned: “Stargate users should redeem assets from these chains (USDC.e, wETH, USDT). If you do not take action before support for the chain is fully terminated, it will result in losing fund access rights.”

The official also advised that users holding Stargate Pool or Stargate Hydra assets should prioritize bridging to chains with deeper liquidity, such as Ethereum, Arbitrum, Base, or BSC.

Removing services doesn’t mean the contracts disappear, but nobody will run verification for you

Here’s a technical detail to clarify first: what is being wound down this time is LayerZero Labs’ self-operated off-chain service, namely the DVN and Executor, not shutting down the Endpoint contract on-chain. The Endpoint contract itself is immutable and will remain in place; in theory, the logic for cross-chain message transmission is not removed.

But in practice, without an official DVN to handle verification and without an Executor to handle delivery execution, cross-chain messages on these chains effectively lose the final official “last-mile” endorsement. For regular users, it feels like the cross-chain functionality of that chain is “down.”

Check the address first—don’t wait until the last day

For regular users, the action instruction in this announcement is straightforward: first check whether your wallet address is on any of these 20 chains. If you hold Stargate-related assets such as USDC.e, wETH, USDT, SUSDC, or SETH, make sure to complete bridging or redemption before the corresponding effective date—don’t wait until the last day to act. On-chain congestion and bridge queues may cause you to miss the window.

Looking at the bigger picture, LayerZero’s wind-down here echoes a stage shift that the cross-chain infrastructure industry is going through: the strategy that previously competed for market share by “supporting as many chains as possible” is being replaced by the reality of “concentrating resources on high-activity chains.”
