Are you a #CosmWasm developer?

This is what happened this week in the Cosmos you should be aware of:

@axelarcore's General Message Passing (GMP) is now available between EVM and Cosmos-based chains.

#CosmWasm 1.3 is on its way and with it a few additions to our beloved structs Addr, Uint* and Decimal* 😎

The Atom Economic Zone is getting traction with 3 proposals:

#790 -> Adopt Liquid Staking Module on the Hub: PASSED
#792 -> Launch Neutron with Replicated Security: PASSED
#794 -> Launch Stride with Replicated Security: Voting (99% passed)

The Liquid Staking Module is probably one of the most interesting developments we have seen lately.

It enables staked ATOM to be instantly liquid staked, without having to wait for the unbonding period of 21 days, increasing capital efficiency! 🔥

#LSM

Atom is spreading beyond the cosmos, this time to #Arbitrum 👀

This is possible because of @axelarcore's GMP mentioned in the first tweet.

Reliable Randomness is now available for the interchain via @NoisRNG 🤩

Needless to say, your chain needs #CosmWasm and #IBC enabled to tap into it.

Here are some resources to get you started:

◽ Docs -> docs.nois.network
◽ Blog -> scripta.network/@noislabs
Finally, the rockstars at @AbstractSDK are challenging anyone to beat them in #HackWasm Berlin.

Abstract is a framework to build CosmWasm #dApps using modules. Think of them as lego blocks, which you can stack together to build your project.

Frustrated by verbose #ComsWasm smart contract tests?

Today I would like to introduce to the @cosmos community the Robot Pattern for stable, readable, and maintainable tests.

If you are a developer, you don't want to miss this one, I promise 😎

Let's dive in! 🧵

1/
From testing 101:

The QA team checks app functionality via the UI. The tester doesn’t care how the application is written as he just interfaces with the UI.

In case of smart contracts, the tester checks at the frontend to interact with the contracts. #smartcontract #testing

2/
So for the tester to check say an asset swap on a #DeFi protocol, it performs the following actions:

• Visit the frontend
• Go to swap page
• Connect wallet
• Select Asset X from the dropdown
• Enter amount of Asset X to swap
• Click Swap
• Verify swap was successful
