Pinknode will offer safe, stable, and scalable API endpoints to Pontem as part of the collaboration, enabling developers to link their dapps to the existing ecosystem of Kusama, Polkadot’s “canary network” for testing new upgrades and features. According to the news announcement, every project that links to the parachain will be compatible with the Diem blockchain.
Finally, the project intends to guarantee that all Polkadot-based decentralized applications (dapps) may interface with Diem through the Pontem Network.
