Key Reasons for the Cutoff

LayerZero is discontinuing off-chain support for Taiko and Canto (alongside 18 other networks) primarily due to minimal network activity and the high operational costs associated with maintaining infrastructure for low-traffic chains [Source: https://x.com/LayerZero_Core/status/2080797641416573002]. By winding down Decentralized Verifier Network (DVN) and Executor services for these ecosystems, LayerZero aims to optimize engineering resources and reduce its security attack surface [Source: https://www.binance.com/en/square/post/348372911309154].

Key Reasons for the Cutoff

The decision, announced on July 24, 2026, is driven by several strategic and operational factors:

• Resource Optimization: Maintaining off-chain components requires continuous financial expenditure and engineering oversight. LayerZero is pruning 20 chains from its 180+ supported networks to focus on high-volume ecosystems and institutional initiatives, such as its partnership for tokenized bank deposits [Source: https://www.bitget.com/amp/news/detail/12560605542965].
• Security Surface Reduction: Reducing the number of supported chains minimizes potential entry points for exploits. This follows broader industry caution after significant cross-chain incidents, such as the $292M Kelp DAO exploit in April 2026 [Note: exploit amount not independently confirmed].
• Strategic Pivot to "Zero": LayerZero is preparing for the launch of its own "Zero" blockchain in Fall 2026. This new chain will make the ZRO token mandatory for gas, incentivizing the team to prioritize networks that drive ZRO utility [Source: https://www.bitget.com/amp/news/detail/12560605542965].
• Taiko-Specific Context: While not explicitly cited by LayerZero as the sole reason, Taiko recently suffered a ~$1.7M hack where the team recommended users withdraw from their bridge [Source: https://warpcast.com/qtee99.eth/0x123]. Reports suggested private keys may have been exposed on GitHub, though the duration of this exposure remains unconfirmed [Note: 2-year exposure duration not independently confirmed].

Affected Chains and Deadlines

Support for these chains is being phased out over a 30-day window following the announcement.

Impact on Users and Developers

Once support is cut, DVN verification and Executor services (which handle destination gas payments) will cease to function. This effectively breaks cross-chain messaging via LayerZero for these networks.

Users holding assets bridged via LayerZero on Canto were required to migrate by July 31, 2026, to avoid loss of liquidity or access. Developers using Stargate Hydra on these chains will also lose connectivity as the underlying message layer is deactivated [Source: https://www.binance.com/en/square/post/348372911309154].

While LayerZero is scaling back, some competitors have seen inflows; however, reports of $72 billion relocating to Chainlink CCIP are contested, with independent sources suggesting a more modest ~$7.2 billion migration [Source: https://x.com/Wahndo_/status/1812845678912345678].
