Research the farming smart contract for Nabla

[prayagd]

Context

In order to distribute farming rewards to Nabla LP providers, we need to research the farming smart contract shared from the Nabla team.

Requirements

• Can this smart contract be transpiled to WASM?
• Can we use the transpiled smart contract as is or do we need to write additional code for it?
• What are the parts smart contract need to rewritten?

Hey team! Please add your planning poker estimate with Zenhub @adelarja @b-yap @ebma @TorstenStueber

[TorstenStueber]

Where is this coming from? I though that Nabla is self-contained and sufficient for our needs, I did not expect that we need to deploy other smart contracts.

[prayagd]

@TorstenStueber this is for distributing rewards for farming LP tokens, the Nabla smart contracts does not include this. This is an additional one.

@gianfra-t I can see that this ticket is in the review column but it doesn't mention any research document in the description. Can you please update it so that it reflects the current state?

[gianfra-t]

Sorry, I forgot to add it here. The research is in this notion page

[ebma]

Nice, thank you. The research looks good 👍 So we can conclude that the provided smart contract can be used for farming with just a minor modification.

I'd consider this ticket done then.

@ebma i see we need to use a SafeERC20 library to make the smart contract compatible with Pendulum. Should the followup ticket be deployment of that farming smart contract along with the SafeERC20 library?

[gianfra-t]

There is a SafeERC20 implementation in the nabla repo if it is useful.

[ebma]

Should the followup ticket be deployment of that farming smart contract along with the SafeERC20 library?

Yes, if you want to have the farming feature, then the follow-up ticket should be about deploying the farming contract mentioned in this ticket together with the SafeERC20 contract used by Nabla.

Cool, new ticket here
