The Ronin Chain Saigon testnet will migrate to the Ethereum mainnet this Thursday

The Saigon testnet of the Ronin chain will migrate to the Ethereum mainnet this Thursday, marking Ronin's return to Ethereum and an upgrade to Layer 2.

The hard fork is scheduled to occur at block height 45528550 (February 5, 2026, 23:58:55 UTC), at which point the testnet chain ID will also be updated to 202601. After the mainnet migration to Ethereum, the mainnet chain ID will remain unchanged.
