Supercharge Your OKChain dApp Development with Particle SDK


A Super Scalable, Compatible L1 Blockchain OKT Chain (OKTC) is an EVM-compatible L1 built on Cosmos with a focus on true interoperability (IBC) and maximized performance. At high scalability, developers can build and scale with low gas fees. The OKT Chain ecosystem and infrastructure, including the all-in-one multi-chain Web3 interface, enables a seamless experience for both developers and users.

Key Features and Benefits

  • High Scalability & Maximized Performance: Based on enhanced Tendermint and Delegated Proof of Stake (DPoS) consensus that can support up to 5000 Transactions per Second (TPS), Web3 applications shall reach their full potential at extremely low cost.

  • Enhanced Interoperability: OKT Chain supports Inter-Blockchain Communication (IBC)nprotocol that — together with the Tendermint consensus algorithm, featuring instant finality — can be used to realize value transmission between Cosmos ecosystem within seconds. Being fully EVM compatible, OKT Chain allows developers to build projects without any learning cost.

  • Developer Friendly: OKT Chain is completely open-source. Anyone can read it, check the progress, comment on it, and help build the ecosystem. OKT Chain also provides native oracle protocol and industry-leader Chainlink for maximum flexibility to access price feeds.

  • Secure: The OKT Chain team offers a reliable smart contract auditing service, making it a genuinely decentralized protocol that avoids the centralization risks of most blockchain networks today.
