Mainnet V2 is here

Fetchhub, our mainnet v2 is here! You will find all information to setup your client and connect on the network and cli-introduction pages. Previous test networks are still available as well for your tests and experiments.

This documentation covers some of the things you need to know in order to prepare for and develop for this new network:

Test Networks

The starting point for most developers will be our Agent Land test network, since this is primarily used for agent development and testing. Agent Land is fully supported by our Agent Framework from version 0.6 and above. If you are developing autonomous economic agents using our latest framework, then moving to Agent Land is relatively straightforward, unless smart contracts are involved.

Agentland and other testnets on the journey have a new address format. Here is a typical example:



These new addresses are not compatible with mainnet v1 or testnet v1. It is expected that users will create new address for agents on the network

Roadmap for Smart Contracts

The v2.0 main-net and our test-nets support a webassembly (WASM) virtual machine VM. When mainnet V2 is released, smart contracts will be developed using Cosmwasm, which will include the ability to develop your contracts in a variety of languages depending on your preferences, such as Rust, Go or Javascript. For more information on Cosmwasm, and Rust, which is the first language to be supported by the Cosmwasm VM, you can go to and
