John Linden, CEO of gaming technology company Mythical Games, said his company his company is testing an "adjacent" blockchain that will be compatible with the Ethereum blockchain.

The deciding factor will be if the Merge n a software update on Ethereum that is scheduled to take place next month n goes as planned, Linden said on CoinDesk TV's "First Mover" show on Wednesday.

lWe have a chain in testnet right now that is fully EVM compatible,r Linden said, referring to "Ethereum virtual machine."

Lindenrs comments come ahead of Ethereum's transition to a proof-of-stake model of maintaining the network and verifying transactions from a proof-of-work one. The shift is intended to reduce transaction times and fees and to increase security.

Linden said Mythical Games has been building the chain over the last couple of years, but Ethereumrs lmassive gas feesr were a drawback. Itrs hard to validate lbig external feesr for users, particularly on a $10 video-game item, he added.

The company now uses the EOS.IO blockchain platform, which Linden said has allowed Mythical Games to create its own forked chain. lWe added our own level of EVM compatibility over the top,r he said. lWe added bridges back to Ethereum.r

lAs EVMrs caught up to proof-of-stake, werve been leaning heavier into that tech stack,r Linden said.

Linden didn't fully disclose whether Mythical Games is moving to the Ethereum blockchain just yet, but said that his company sees lsome efficiencies [in] having a true kind of EVM chain behind the scenes.r
