@w1nt3r on NFT Development, His EVM Course, and Winning as an Honest Builder in Web3 Nov 17, 2022

Show notes

Winter has been prolific on Twitter & in his web3 journey. He’s worked on projects for the Nouns and Loot communities, and produced really interesting projects of his own including ERC1155U, Runes of Ethereum, & Hot Chain SVG.

In this episode, we talk about the benefits of building in public, gas optimization, innovating in NFTs, and how to succeed as an honest builder in web3.

Winter is *legit*, and if you’re looking for a podcast episode that takes you away from the mania that’s happened throughout the last week in crypto, this episode will do that for you. Winter will bring you back to what matters: building

So give it a listen, and let us know what you think.

Igor Yalovoy - Founding a DeFi Protocol, Unlimited Contract Sizes, & Solidity Best Practices Nov 10, 2022

Show notes

Igor has a really interesting story. Babylon was a DeFi protocol that ended up shutting down after the Rari capital exploit, but the team gave the project a high integrity effort and it sounds like they learned many things during the journey.
Igor walks us through what it was like launching a new DeFi protocol during the bull market, and also talks us through the lessons he took away from the experience.
We cover subjects like testing smart contracts, preparing for audits, optimizations he’s product of, solutions to the sometimes oppressive contract size limit in solidity, & how he personally levels up as a solidity dev.
This ep is a treasure trove of information for DeFi founders and technical folks.

Yorke Rhodes on Hyperlane, Cross Chain Tech, and Solidity Nov 03, 2022

Show notes

Stream payroll with Superfluid: https://use.superfluid.finance/payroll

Today’s guest is Yorke Rhodes - founding engineer at Hyperlane, a protocol which serves as a platform for building cross chain applications.

Yorke is very knowledgable about building smart contracts. He was previously at Celo and has spent his career going deep on solidity before joining Hyperlane (which was previously known as Abacus), as a founding engineer.

In this episode, Yorke and I talk through the details of Hyperlane’s system for sending and receiving messages cross chain, and talk through cross chain tech more generally. We also talk through things like how Hyperlane thinks through developer experience & building APIs, and Yorke’s thoughts on smart contract security. Finally, we wrap up by asking Yorke what his favorite design patterns and optimizations are - something we always love asking.

If you’re a solidity developer with an interest in cross chain technology, this episode is for you.

Cami Ramos Garzon - Developer Experience, Fuel, & Bringing Crypto to LatAm Oct 27, 2022

Show notes

Today we have Cami Ramos Garzon - aka Camiinthisthang on twitter. Cami is a Colombian-American engineer who began her career as a software engineer at Paypal before ultimately getting involved in web3. She’s a natural communicator who quickly found a fit in developer relations for some of the industry’s largest and fastest moving protocols like the Graph. Today, she works as a DevRel at Fuel Labs, where she’s helping to build out a high quality developer experience for engineers who want to build applications on top of the FuelVM. In addition to this, she’s prolific on twitter and before Devcon had a post go viral on why crypto needs to focus on Latin America if it wants to reach its full potential.

This episode was recorded live during Devcon week.

Odysseas.eth: Cross Chain Tech, Good Design Patterns, and the Sovereign Stack Oct 20, 2022

Show notes

Today’s guest is Odysseas.eth, an engineer at Nomad who has provided a lot of value to the space as an engineer and open source contributor to various projects such as Foundry. Odysseas has a passion for decentralization, and in this episode, we discuss the technical details of what he calls the Sovereign Stack - a suite of tools he feels are important for crypto natives seeking to live decentralized lives.

We also dive deep on cross chain messaging, favorite design patterns in the Foundry codebase and Odysseas’ own work (which include a really cool script for tracing contract storage I thought was awesome), and the importance of focus for engineers working in the space. This is a wide ranging conversation that decentralization maxis and protocol engineers alike will enjoy.

@Vex_0x: Huff, Low Level Languages, & the EVM Oct 13, 2022

Show notes

Today’s guest is Vex, a software engineer, smart contract developer, and major contributor to Huff - a low level assembly language for the Ethereum Virtual machine.

Vex knows a ton about the EVM at the low level, and we go deep into why Huff is a great language to learn for building incredibly gas efficient contracts. Huff is also being used more and more as an educational tool, as it allows you to build programs that are, as Josh says, equivalent to ‘bare metal ethereum.’

If you’re interested in low level smart contract languages, and developing a deeper understanding of how the EVM works, you’ll love this episode.
