StarkEx leverages STARK technology to power scalable, self-custodial trading and payment transactions for applications such as DeFi and gaming.

StarkEx currently supports ETH, synthetic assets, and the following tokens:

  • ERC-20

  • ERC-721

StarkEx can also support tokens on other EVM-compatible blockchains.
