Litentry partners with Patract to foster simulation of network interaction

2 min readMar 30, 2021

We are proud to announce our partnership with Polkadot Wasm smart contract solution provider Patract.

Under this partnership, Litentry will develop Litentry’s ink! smart contract based on Patract’s Redspot tool, allowing DApp developers to easily integrate cross-chain identities and data on Litentry, identity calculations in different scenarios according to their own algorithm logic, and customize their own user reputation and grading system.

In addition, Litentry expands the contract running sandbox environment Europa provided by Patract, increases the accessibility of Litentry Pallet data, and can directly simulate the interaction with Litentry nodes.

Quotes from Litentry and Patract:


“Patract’s tools make it more convenient for us to write contracts, test contracts, and simulate the real Litentry network. This is due to the enhanced execution environment log system, which makes it easier to locate bugs in the contract. Patract’s engineers gave a lot of online guidance during the use process, They are very powerful。”

— Hanwen Cheng, Litentry CEO


“Litentry’s identity aggregation and verification function provides real-time credit data of the identity owner for blockchain applications. These data are critical to the composability of upper-level DeFi applications. With the platform advantages of Wasm contracts, more community developers can be accepted. Participate in the provision of data and build upper-level DApps based on these data to create a DID identity platform ecology.”

— Lipeng Yue, Patract Founder
