RIZON CosmWasm Smart Contract_Testnet (a.k.a flora-2)

Published in
4 min readApr 26, 2023


Hello, this is the RIZON team.

Before service development, the RIZON team independently configured flora-1 Testnet to use the multi-smart contract platform (CosmWasm) and is conducting tests to identify problems with CosmWasm or module stability.


We also track and verify the latest versions of open source used by RIZON Blockchain.

The RIZON team has prepared and released the flora-2 testnet to provide an improved user experience and to introduce and test new features of the upgraded open source. In this flora-2 testnet, COSMOS-SDK V0.45.15 and COMETBFT V0.34.27, which has been changed from TENDERMINT, have been applied, COSMWASM has been applied to V1.2.1, and IBC has been released to V4.2.0. If there are no problems in the future test progress, these fixes will be reflected in the groot testnet and titan mainnet through proposals.

The information of flora-2 testnet and tutorial of CosmWasm smart contract are shared below, so please check it out and try to develop and test smart contract DAPP through flora testnet.

For the development of RIZON’s ecosystem, we encourage you to actively participate in the test to ensure that there are no problems in using the new platform. More information can be found on the RIZON&ATOLO discord channel.



  • cosmos-sdk v.0.45.15
  • cosmwasm v.1.2
  • ibc version 4
  • cometbft v.0.34.27

About CosmWasm & IBC

CosmWasm is a framework for building new blockchain applications that works with the Cosmos SDK using the Tendermint protocol. The framework is built on WebAssembly technology, which allows you to create highly secure and portable blockchain applications. With CosmWasm, developers can write smart contracts in the Rust programming language and create decentralised applications (DApps) that include features such as cryptocurrency issuance, transfer, and conditional transactions. As a tool for creating highly secure and portable blockchain applications, CosmWasm will be of great help to developers working on new blockchain applications.

Inter-Blockchain Communication (IBC) is a protocol that enables communication between blockchains. IBC will enhance the interoperability of the Cosmos blockchain ecosystem, as assets and data can be transferred between multiple Cosmos SDK and Tendermint-based blockchains via IBC.

Adventures with Rizonians

The RIZON team will continue to pave the way for RIZON to navigate the Web3 economy to create a new era as a digital currency and asset hub.


RIZON Blockchain is a digital currency and asset hub that provides a platform for fiat currency around the world so they can be securely issued and enable businesses to interoperate. RIZON Blockchain will enable interoperability between sovereign blockchain networks and allow these networks to utilize a vast pool of liquidity, seeing that it serves the business needs of individual projects. RIZON Blockchain has a strong network-based background and can boost the inflow of participants into the ecosystem and help with diversifying the businesses.
