Wasm Contract Summary from Alliance Members(August,2021)


Patract Open Platform’s goal is to promote the large-scale popularization of Wasm contract technology in the Polkadot ecosystem. Patract Open Platform (POP for short, Wasm Contract Technology Alliance) will jointly promote the construction of public infrastructure and the evolution of contract technology, and provide brand promotion and capital support, then creating a strong alliance for Wasm contract ecosystem.

Wasm Contract Progress

Cycan — GVM Bridge Github

GVM Bridge is a set of virtual machine intermodulation systems. Through the GVM Bridge system and the VM interconnection protocol, smart contracts between VMs can be invoked to achieve resource consolidation, and resources from different VMs can be used immediately without migration, thus improving resource utilization.

  • The contract intermodulation V0.1 has been integrated to the chain node.
  • Used GVM-Bridge pallet to debug in Runtime.
  • Added pallets such as staking, session, babe to the experimental independent chain, realizing the babe+grandpa consensus scheme.
  • The EVM contract module will be added to the experimental independent chain soon.

Coinversation — Deploy Wasm contract on Astar

At present, the Coinversation team has completed all the back-end code development of Wasm smart contract. At this stage, Coinversation is promoting the deployment of Wasm contracts to the Astar smart contract platform. During the deployment process, the team faced the problem that the Wasm contract can’t produce blocks after deployment. Currently, the problem has been submitted to the Parity official, waiting for the Parity team to fix the problem. In addition, the Coinversation team has first deployed the EVM DEX, which has been launched on the BSC chain this month. The team plans to complete the deployment on the Shiden Parachain in the next 1–2 months.
