In Brief:
- DeFi Kingdoms (official site) is sunsetting DFK Chain on Aug. 28, 2026, relocating the game to Avalanche’s C-Chain.
- The migration extends only to DFK-native assets. JEWEL, BTC, ETH, AVAX, USDC and any other bridged token must be withdrawn by the holder, or it disappears permanently.
- According to the team, the project is not winding down — an SDK is planned for third-party developers who want to build on DFK’s systems and game mechanics.
Aug. 28, 2026 is the day DFK Chain goes offline, and any bridged token still parked on the network when it does will be impossible to recover.
“After careful consideration, DFKChain will officially sunset on August 28th, 2026,” the team wrote in a July 31 post on X titled “DFK Chain Sunset & The Road Ahead.” DeFi Kingdoms said the call came after months spent reviewing the project’s long-term infrastructure together with the Avalanche team.
Players should visit DFK Chain as soon as possible to bridge non-native tokens out to their chain of choice.

Players have about three weeks to act.
What the migration does not cover
Only assets native to DeFi Kingdoms are part of the migration process. Anything beyond that falls on the holder.
Bridged tokens such as JEWEL, BTC, ETH, AVAX and USDC need to be moved off DFK Chain by the players themselves, and once the chain is retired those balances cannot be recreated or recovered, the team said. The same caution appears on the game’s own site: non-DFK assets have to be bridged out ahead of the date or they will be permanently lost.
Bridging JEWEL to Avalanche C-Chain is already possible. DeFi Kingdoms warned players against waiting until the final days.
“Players should visit DFK Chain as soon as possible to bridge non-native tokens out to their chain of choice,” the project said.
Two steps before bridging
The team’s pre-shutdown instructions say smart wallet users have to transfer their assets into a standard wallet before anything else.
There’s extra work for liquidity providers. Every LP position should be dissolved, DeFi Kingdoms said, including pools built purely from DFK-native assets.
Those sitting on DFK-native assets should hold off for now. Additional technical guidance covering their migration will land before the deadline, per the team.
The game moves to C-Chain
The chain is going away; the game isn’t. DeFi Kingdoms said it intends to stay up and running by migrating to Avalanche C-Chain, promising more details in the coming weeks, and added that cooperation with the Avalanche team is ongoing to complete the transition securely.
“We’re looking forward to the next phase of DFK on @avax c-chain in the not too distant future and hope you’ll join us for it,” the project said.
The team also stressed that shutting the chain down does not signal the end of the project. An SDK is on the roadmap so outside developers can build services drawing on DFK’s systems and game mechanics, and the studio said longer-term development plans are still being worked out. Neither came with a launch date.
Background
DFK Chain debuted alongside the Crystalvale expansion, constructed on Avalanche’s Subnet technology. It handled gameplay transactions in Crystalvale, hosted the Crystalvale DEX, and used JEWEL as gas so players never needed an external token to cover fees.
DeFi Kingdoms’ other realms live elsewhere and are untouched by this shutdown. Serendale was relaunched on Kaia, while the PvP Colosseum operates on Metis.
The chain first went live on March 30, 2022, as Avalanche’s first subnet.
