The community can [run their own Relayer](/docs/operate/relayer/run-relayer) to keep message delivery operational. * **Validators** — Abacus Works will wind down its Validators for these chains. Chain teams and ecosystem partners can [run their own Validator](/docs/operate/validators/run-validators) and [reach out to the Abacus Works team](https://github.com/hyperlane-xyz/hyperlane-monorepo/discussions) to update the [default ISM](/docs/reference/addresses/validators/mainnet-default-ism-validators). If you're building on any of these chains, plan your migration before the last supported date. After the listed date, Abacus Works will no longer operate agents for that chain. To take over agent operations, refer to the [Validator](/docs/operate/validators/run-validators) and [Relayer](/docs/operate/relayer/run-relayer) guides. | Chain | Domain ID | Chain ID | Last Supported Date | | --------------------- | ---------- | ---------- | ------------------- | | Ancient8 | 888888888 | 888888888 | July 16, 2026 | | AppChain | 466 | 466 | August 21, 2026 | | Arbitrum Nova | 42170 | 42170 | May 10, 2026 | | Arcadia | 4278608 | 4278608 | August 18, 2026 | | Artela | 11820 | 11820 | May 10, 2026 | | Astar | 592 | 592 | July 10, 2026 | | Aurora | 1313161554 | 1313161554 | May 10, 2026 | | B² Network | 223 | 223 | August 10, 2026 | | B3 | 8333 | 8333 | May 10, 2026 | | Berachain | 80094 | 80094 | September 30, 2026 | | Bitlayer | 200901 | 200901 | August 10, 2026 | | Blast | 81457 | 81457 | September 30, 2026 | | Boba Mainnet | 288 | 288 | August 10, 2026 | | Botanix | 3637 | 3637 | July 31, 2026 | | Chiliz | 1000088888 | 88888 | July 10, 2026 | | Core | 1116 | 1116 | July 16, 2026 | | Cyber | 7560 | 7560 | July 16, 2026 | | Degen | 666666666 | 666666666 | May 10, 2026 | | Dogechain | 2000 | 2000 | May 10, 2026 | | Endurance | 648 | 648 | June 7, 2026 | | Everclear | 25327 | 25327 | May 10, 2026 | | EVM on Flow | 1000000747 | 747 | August 10, 2026 | | Fantom Opera | 250 | 250 | May 10, 2026 | | Flare | 14 | 14 | July 16, 2026 | | Fluence | 9999999 | 9999999 | May 10, 2026 | | Forma | 984122 | 984122 | October 31, 2026 | | Fuse | 122 | 122 | July 16, 2026 | | Gravity Alpha Mainnet | 1625 | 1625 | July 16, 2026 | | Harmony One | 1666600000 | 1666600000 | May 10, 2026 | | Hashkey | 177 | 177 | August 10, 2026 | | Hemi Network | 43111 | 43111 | August 10, 2026 | | Immutable zkEVM | 1000013371 | 13371 | August 28, 2026 | | Incentiv | 24101 | 24101 | July 10, 2026 | | Kaia | 8217 | 8217 | July 16, 2026 | | Lit Chain | 175200 | 175200 | June 16, 2026 | | Lumia Prism | 1000073017 | 994873017 | August 14, 2026 | | Manta Pacific | 169 | 169 | July 10, 2026 | | Matchain | 698 | 698 | August 14, 2026 | | MegaETH | 4326 | 4326 | September 30, 2026 | | Merlin | 4200 | 4200 | May 10, 2026 | | MilkyWay | 1835625579 | milkyway | May 10, 2026 | | Miraclechain | 92278 | 92278 | June 29, 2026 | | Molten | 360 | 360 | June 1, 2026 | | Moonbeam | 1284 | 1284 | May 10, 2026 | | Morph | 2818 | 2818 | August 10, 2026 | | Neutron | 1853125230 | neutron-1 | March 14, 2026 | | Nibiru | 6900 | 6900 | August 10, 2026 | | Noble | 1313817164 | noble-1 | August 10, 2026 | | Ontology | 58 | 58 | July 10, 2026 | | opBNB | 204 | 204 | July 16, 2026 | | Oort | 970 | 970 | August 14, 2026 | | Orderly L2 | 291 | 291 | July 16, 2026 | | Peaq | 3338 | 3338 | August 10, 2026 | | Plume | 98866 | 98866 | August 10, 2026 | | Polygon zkEVM | 1101 | 1101 | May 10, 2026 | | Polynomial | 1000008008 | 8008 | May 10, 2026 | | Prom | 227 | 227 | July 31, 2026 | | RARI Chain | 1000012617 | 1380012617 | July 16, 2026 | | Reactive Mainnet | 1597 | 1597 | August 10, 2026 | | Redstone | 690 | 690 | May 25, 2026 | | Ronin | 2020 | 2020 | August 14, 2026 | | Scroll | 534352 | 534352 | May 10, 2026 | | Sei | 1329 | 1329 | September 30, 2026 | | Shibarium | 109 | 109 | July 16, 2026 | | Sonic | 146 | 146 | August 10, 2026 | | SOON | 50075007 | 50075007 | August 14, 2026 | | Sophon | 50104 | 50104 | May 20, 2026 | | Story Mainnet | 1514 | 1514 | May 10, 2026 | | Stride | 745 | stride-1 | July 10, 2026 | | Superposition | 1000055244 | 55244 | May 10, 2026 | | Swellchain | 1923 | 1923 | June 28, 2026 | | TAC | 239 | 239 | August 28, 2026 | | Taiko | 167000 | 167000 | September 30, 2026 | | Tangle | 5845 | 5845 | May 10, 2026 | | Torus | 21000 | 21000 | July 10, 2026 | | Vana | 1480 | 1480 | July 29, 2026 | | Xai | 660279 | 660279 | July 16, 2026 | | XRPL EVM | 1440000 | 1440000 | July 10, 2026 | | Zero Network | 543210 | 543210 | June 1, 2026 | | ZetaChain | 7000 | 7000 | July 16, 2026 | | Zircuit | 48900 | 48900 | July 10, 2026 | | Zora | 7777777 | 7777777 | May 10, 2026 | *Chain and domain IDs sourced from the [Hyperlane Registry](https://github.com/hyperlane-xyz/hyperlane-registry).*
