Cardstack is a blockchain technology company that is developing an open-source framework and consensus protocol to make blockchains more usable and scalable. Their goal is to create a decentralized modular smart contract ecosystem. The Cardstack network is powered by the Ethereum-based CARD token.

Fantom is developing a smart contract platform based on a directed acyclic graph (DAG). They hope to address the scalability issues of current decentralized platforms. Instead of a blockchain, Fantom's Lachesis Protocol uses a directed acyclic graph to confirm transactions asynchronously. This transaction history is immutable and cannot be modified. The platform's Opera Chain will consist of three layers: an application Layer, Opera Ware Layer, and Opera Core Layer. Fanotm issued an Ethereum-based token in 2018.

TomoChain is a DApp development platform compatible with Ethereum smart contracts. Their goal is to enable faster and cheaper transactions. Their network will have a Proof-of-Stake (PoS) consensus mechanism, with a system of 150 Masternodes. TomoChain will be compatible with Ethereum-based smart contracts, and will allow users to issue their own tokens. The company has offices in Singapore, Japan, and Vietnam.
