Testnets
Jupiter0.2
Jupiter is a series of common good testnets developed and maintained by Patract, including PoA fast independent chains and Rococo parachains. It integrates different versions of contract models, contract languages, resource models, contract governance, cross-chain standards, and runtime support.
Community parachains can develop custom requirements based on Jupiter, and take advantage of the amplification effect of the Wasm contract platform to better utilize its advantages in storage, privacy, messaging, and product operations. Community DApp developers can conduct early contract development and testing based on Jupiter, and then deploy to any parachain that supports Wasm contracts.
Resource model
Jupiter will first deploy the existing resource model for computing gas costs and storage rent developed by Parity, and at the same time collect community opinions and feedbacks, and work with Parity to improve this resource model.
Contract standards
Jupiter will work with the community to define a set of protocol on fees, upgrades, migration and destruction, and formulate upper-level business standards similar to ERC20 to promote collaboration among multiple participants in the industry.
Runtime support
Jupiter will provide support for pallets such as zero-knowledge, random numbers, domain name system, IPFS, bridge, and cross-chain messaging at the Runtime level to adapt to the differences in the Runtime environment of different parachains.
On-chain Contract Technology
Off-chain Development Support
Redspot0.4
Contract development workflow and scaffold. Redspot can standardize contract development, shield the underlying compilation details, and connect to other tools as a core component of Patract.
Europa0.3
Contract running sandbox environment. Europa is an independent and complete running environment for Runtime that includes Contracts Pallet. It does not require consensus and P2P, so can quickly develop and debug contracts.
zkMega0.2
Zero-knowledge proof support. zkMega provides on-chain runtime support for multiple cryptographic curves and off-chain development tools to facilitate the development of zero-knowledge contracts.
Himalia0.2
Multi-language contract SDK. Himalia supports developers to interact with contracts in multiple development languages from different clients, including: PatractGo, PatractPy, PatractJ, PatractN etc
Elara0.3
Instant and scalable Polkadot API. Elara provides RPC interfaces for relay chains and parachains, saving developers the trouble of deploying and operating multi-chain nodes.
