0xtekgrinder Builder Journey

[0xtekgrinder]

Hello everyone,

I am a blockchain developper (mostly coming from Solidity language) currently living in France and during my journey here, I will try to contribute as much as possible to the success of gno.

In my first week, I have started on the ideation of a gno oracle + agents to provide any kind of data from web2 onchain such as x followers, stars on a github repository and so on. https://github.com/0xtekgrinder/gno-oracle

I have also created one issue to ease access of realms within gnoweb gnolang/gno#2762
And created my first PR to fix an issue in gnoweb and improve it gnolang/gno#2757

[0xtekgrinder]

To give update on the last two weeks,

I have continued working on this PR on gnoweb and finished it
I created a POC oracle from scratch not to be influenced with gnorkle with a fee system when querying data.

I then tried to fix this bug but without real success so I shared my progress for another contributor to try to tackle it.
I started to discover a bit tlin and created my first PR to add json support to later add it to gnopls.

And finally, I started the creation of a periodic feed on gnorkle to have an example of VRF with multiple agents creating a random data.

During this week,

I have focused mainly on tlin by creating a few PRs. I wanted first to add tlin to gnopls however to make it happen, it needed to be usable as a library without any read/calls to be used inside an assembly module.

To make it happen, I created a first PR to refactor the code + add a function to parse source directly.
Then, a little PR to finalize the process by exporting the engine and replacing gnoswap-labs with current organization (gnolang).

I started a PR inside gnopls to add tlin which is still WIP as it is using the internal NewEngine function.

I added graphviz output for tlin inside this PR.

And finally, I made few fixes to my gnoweb PR asked by thehowl.

This week,

My main focus was starting on a new bigger project aiming to create an automated liquidity management DeFi project on top of gnoswap to have positions always in range of the current tick.

This project will be in three parts:

• the realms for the onchain logic (deposit/withdraw/collect-fee/rebalance)
• a frontend to let users interact with the deployed vaults
• a keeper to rebalance the vault positions under certain conditions.

So, I have done a lot of research on gnoswap repository to know how to make it happens and created my first PR inside the new repository to add a first version of the realms to create a new vault and deposit/withdraw into it.

In the meantime, I have also finished my PR to add tlin inside gnopls
And created an issue to improve tlin by adding severity of issues

This week,

I have mainly worked on a pretty big feature on tlin to add a configuration file that will be loaded to activate rules and override default rules. It also includes a pretty big refactor to add a severity into issues (info, warning and error).

The other big part was continuing working on the gnoswap vaults with an improvement of the realms to add multiple fix:

• extra security checks
• reposition function
• width of vaults
• minimum amounts when depositing and creating a new vault
• few fixes with wrong amounts used and so on

And I have started to create the frontend to deposit / withdraw into the vaults

During this week,

I have focused on autoswap (ex gnoswap vaults) by creating a few PRs:

• feat: contracts 0xtekgrinder/autoswap#4 so onbloc and leo could review the realms independently.
• Feat/realms improvments 0xtekgrinder/autoswap#8 which extract the commits from #4 improving the realms and fixing some issues
• tests: start of vault tests + token_register 0xtekgrinder/autoswap#7 also extracted from #4 for the start of the tests of the vault + all of the tests for the token registry
• doc: new README explaining the project and how to launch it 0xtekgrinder/autoswap#5 to add a README explaining the project
• chore: add MIT license 0xtekgrinder/autoswap#6 to add the MIT license to the project

Meanwhile I created a PR in tlin to set an appropriate default severity of each rules.
And then created another PR into gnolang to finish acl realm.

From this resulted two issues:

• remote state downloading and usage in gno run|test gno#2989
• (gnovm) Fmt function in testing environment crash the whole function gno#2988

[0xtekgrinder]

In this week,

I have focused on bigger PRs with:

• refactor: use text templates for formatting issues gnoverse/tlin#98 to refactor the whole formatting of the issues to use text/template package for an easier update over time
• tests: vault tests 0xtekgrinder/autoswap#9 to add the missing test for the creation of the vault + deposit/withdraw using mocked GRC20
• feat: tx-indexer and frontend integration 0xtekgrinder/autoswap#10 to implement the tx-indexer inside the frontend and have a docker-compose to launch the frontend + tx-indexer

For my grant renewal:

O1: Improve tlin to be able to replace gno lint with more features and so on
KR1: Add more rules related to regex and more advanced gnovm specialties
KR2: Improve performances of the linting process
KR3: Improve inner working of the linter (formatting, rule types ...)

O2: Continue building a useful library of realms in p/examples
KR1: Add more realms that can be useful for DeFi overall with math computation, token transfers, vaults abstraction ...
KR2: Develop and finish more realms with a more general purpose such as acl

O3: Continue to contribute to gnolang repository
KR1: Tackle more issues related to (formatter, gnovm or gnodev)
KR2: Continue to contribute to gnorkle by adding more different types of feeds and making it prod ready
