Introduce yourself here!

Hi All,

I’ve just joined the Zeppelin Research team, working from Melbourne, Australia. I’m excited to help this ecosystem grow quickly and safely.

When I’m not on the internet, I’m playing guitar, piano, saxophone or basketball.


Welcome to the community @Joe :wave:

A good place to start learning is the #general:guides-and-tutorials category.
We would appreciate your feedback on the guides, please let us know what could be better and what guides we are missing.

Feel free to open a topic in the #support category if you have any questions.

Look forward to hearing about your blockchain programming journey. :smiley:


Welcome @nikeshnazareth to the forum, and to the Zeppelin Research team.

Great to see people from Melbourne :australia: on the Zeppelin team.

See you around.

Hello everyone. I was led here, somewhat indirectly, by @abcoathup posting a poll over on Peepeth.

I started blogging about crypto in the Autumn of 2017, but was on board well before then. Life (travel, career change) has kept me from blogging full time for quite a while, but I’m still steeped in the blockchain ecosystem. I’m a writer and a programmer, but it’s hard to do both well in the same day… After wrapping my head around things philosophically, I decided to focus on getting a more technical perspective.

I’m currently in the B9Labs blockstars program and hoping to be in Truffle University by ~ the end of the month.

Love the OpenZeppelin libraries and community spirit. Glad to be here.


Welcome @CallMeGwei to the Zeppelin community! :wave: Great to have you here.

Would appreciate any feedback you had on our #general:guides-and-tutorials as you continue to learn smart contract development.

I would recommend having a play with Ethernaut. It is a fun way to get yourself to learn more about smart contract security. There are multiple community solutions already, but you could also flex your writing skills and add to these.

Please feel free to ask any smart contract development questions you have in the forum (general or specific to OpenZeppelin and ZeppelinOS).

I know @CallMeGwei from his fantastic writing on Peepeth and his blog, and also had the pleasure of his company and friendship at #buidl_bali retreat.

Welcome @CallMeGwei, great to have you here!

This would be awesome!

Cool! Mind telling us more about this? Feel free to open a thread to share your experience with the community :slight_smile:


Hi I’m Hassan Abdel-Rahman,
I’m a developer at Cardstack ( and we’re working on building out a decentralized multi-currency payment and billing network (amongst other things).



I’m Angel “Java” Lopez, software developer, interested in Blockchain technology, and Ethereum implementations. Currently, I’m working in RSK, an Argentinian startup building and running a blockchain based on Ethereum.

I’m from Buenos Aires, Argentina.

I’m using Zeppelin Solidity.

I expect to learn from and, maybe in the future, add value to the community


Welcome @habdelra to the community. Thanks for the intro.

Are you building an ERC777 token or looking to use them in Cardstack?

Yes, most likely. Right now we have an ERC-20 token, but we’ll likely be upgrading it to an ERC-777. Additionally we have some contracts that we are developing that we want to be ERC-777 tokenRecipients.


Thanks @habdelra.

Is Cardstack token upgradeable or would you have to migrate?

If you have any feedback on the OpenZeppelin ERC777 implementation in the release candidate, we would greatly appreciate it.

It’s a ZOS upgradable contract. Sure, I’ll definitely leave any feedback that I have. thanks!


Hi @ajlopez

Welcome to the community.

What are you currently working on at RSK?

Can you tell us what you are using OpenZeppelin or ZeppelinOS for?

For learning and adding value to the community a good place to start is going through the existing guides in the #general:guides-and-tutorials category and feedback on what we can improve on.

You can contribute to the Ethernaut or OpenZeppelin projects or learn by helping answer questions in the forum or write a guide in the #general:guides-and-tutorials category.

Great to have you here.

Ethernaut is a fun way to learn about smart contract security and there are Ethernaut Community Solutions for many of the levels.

If you have any questions, please let us know in the forum. Thanks

Hi everyone, my name is William and I’m a developer from Italy.
I’ve been working as a front-end developer for most of my carrer, but in the last year and a half I started learning and building on Ethereum.
I’m currently working on a defi project built on top of various lending protocols, and I’m trying to use zeppelinOS :slight_smile:


Hi @bugduino thanks for introducing yourself. Great to have you here.

hi everyone! Jim Zhang from We are a startup as part of ConsenSys and working in partnership with AWS and Microsoft to provide cloud based blockchain as a service platform.

We’ve been using OpenZeppelin for our need in high quality Solidity code, in particular when we recently announced our tokens support in Consensus2019.

Met @albert and got introduced to this community. Mainly want to participate and contribute to the growing coverage of the OpenZeppelin library for common patterns such as Hashed Timelock based Atomic Swaps. Really excited to be here!


Hi @jijordre welcome to the community and thanks for introducing yourself.

Let us know if you have any questions.
