My guest today goes simply by the name Martin. Martin is an EVM and Web3 Developer most famous for creating the Higher memecoin on Farcaster. Over the past few weeks, Martin has thrown himself into building one of the most creative and exciting Social Media Agents, Aether. Aether is a semi-autonomous Agent who communicates with the public through Faracster. Followers can prompt Aether for a response simply by @-mentioning them on Farcaster. In its first couple of weeks since launch, Aether has learned several fascinating new behaviors. With the help of some of its online interlocuters, Aether quickly learned how to create and reward HIGHER token denominated bounties by interacting with fellow Farcaster bots Bountycast and Paybot. In this interview, Martin and I go deep on his work in the Nouns ecosystem, how this informed his development of $HIGHER, and perhaps most fascinating of all, the technical details of how he built Aether. It was great getting to speak with Martin, who is a brilliant and high agency developer pioneering experiments at the intersection of society and blockchains. I hope you enjoy the show.

My guest today is Nitya Subramanian, founder of Capsule. Capsule is an embedded wallet SDK that leverages Passkeys, MPC, and AA Smart Accounts to simplify the user experience around wallet creation and transaction signing. Apps that integrate Capsule's embedded wallet SDK authenticate users by their email address. Capsule creates a Passkey for each user, which is configured as a signer on a 2/2 Multi-Party Computation. This MPC, in turn, is the signer on a 4337 smart account. Users that have created a Capsule account in another app will be able to access it in any future app they log into with the same email address. In other words, Capsule is a cross-domain embedded wallet provider. In this conversation, Nitya explains the MPC setup underlying Capsule, and provides hints at the team's forthcoming release, which aims to allow secure cross-app smart account access, programmable MPC permissions, and automations for common actions like Dollar Cost Averaging. It was great talking to Nitya about Capsule, which is making strides in the challenging domain of cross-app embedded wallets for a mainstream audience. I hope you enjoy the show.

My guest today is Konrad Kopp, co-founder of Rhinestone. Rhinestone is an exciting project that's researching and developing smart account modules atop the ERC-4337 Account Abstraction standard. AA modules promise to allow smart contract account owners to safely add new functionality and permissions to their accounts, without having to upgrade to new smart contracts. The module pattern described in the draft ERC-6900: Modular Smart Contract Accounts and Plugins aims to create an ecosystem of interoperable modules to augment the various 4337 implementations that choose to support it. On this episode, Konrad and I discuss the different approaches to account abstraction contract architecture, including Safe and the ERC-2535 Diamond standard. We dive into the details of ERC-6900, and discuss the compelling Rhinestone video demo, which shows how a user might activate and disable smart account modules like Passkey validation, dollar cost averaging, and recurring payments. We also cover the grant that Rhinestone recently received from the Ethereum Foundation's 4337 team to develop a Module Registry, a public goods venue where security audit firms and others can attest to the safety of specific modules.

Smart contract wallets are gaining traction amongst devs, because they offer several advantages over traditional EOA accounts. ERC-4337, the Account Abstraction EIP, proposes a standard for creating smart contract accounts that can have interchangeable signers and authentication schemes, allow for gas to be paid by third parties, and create a new mempool of transactions that can be bundled and put onchain by motivated third parties. My guests today are Will Hennessy and Noam Hurwitz, who work on Alchemy's Account Abstraction team. In this episode, Will and Noam walk me through the ins-and-outs of Account Abstraction. We discuss the actors in the lifecycle of an AA transaction, how different signing schemes like Magic link and onchain r1 verification fit in, and how AA wallets will connect to dapps. We also dive into Alchemy's latet offering, AccountKit, which provides a suite of options for building smart contract accounts. It was fantastic getting to talk to Will and Noam who are knowledgable builders making quality implementations at a crucial software frontier.

My guest today is Sam Hart. Sam is a developer, artist, and biochemist. He is Head of Product & Strategy at Skip Protocol and co-founder at Timewave Labs. He has contributed to the Cosmos ecosystem for years, and is also co-founder of Folia, a blockchain art collective. On September 1, 2023, Sam wrote a long and detailed post to the MakerDAO forums pitching Cosmos as an interesting option for the appchain aspect of Maker's endgame. Inspired by that post, this episode is an introduction to Cosmos for EVM devs. In this conversation, Sam and I discuss the major components of Cosmos: CometBFT, Cosmos SDK, Inter-Blockchain Communication (IBC), VMs like CosmWasm, and client tooling like CosmJS. We also compare the design philosophy of Cosmos and Ethereum. Good starting points for interested builders are included at the end of the interview. It was fun chatting with Sam about Cosmos, which is an ambitious project whose many flexible affordances can make it challenging to get a handle on. My thanks to Sam for sharing his knowledge. I hope you enjoy the show. As always, this show is provided as entertainment and does not constitute legal, financial, or tax advice or any form of endorsement or suggestion.

My guests today are Himanshu Retarekar and Jebu Ittiachen, two of three co-founders of Obvious. Obvious is a smart wallet company with three products. The Obvious Wallet is a multi-chain 4337 account abstraction smart wallet that was among the earliest full featured AA consumer products on the market. Obvious Embed is an AA wallet that third-party devs can integrate into their own dapps. Obvious Money is a stablecoin focused smart wallet app aimed at emerging markets in Africa and South America. On this episode we discuss the team's path from building a traditional EOA software wallet to account abstraction smart wallets. We get into the tradeoffs of Shamir, MPC, and Passkeys, and the challenges building smart wallets in a massively multichain world. We also talk about fiat money platform incumbents, like M-Pesa, India's Unified Payments Interface, IBAN, and how crypto fits into the mix. It was a pleasure chatting with Himanshu and Jebu who are moving quickly at the intersection of cutting edge smart wallet tech and global consumer applications. I hope you enjoy the show.

Today, I'm joined by Vivian Phung. Viv is the 23 year old solo founder of Snowball, a Web3 dev tools provider focused on mobile apps and webapps. Snowball's first product, Igloo, will give developers a simple solution for SSO authentication, AA smart wallet, and onramping in one SDK. Igloo is currently in private alpha on testnet. Prior to starting Snowball, Viv was co-founder of Dora, a multichain block explorer search engine, and she was an engineer on the Instagram feed team before that. In this conversation, Viv and I dive into the challenges facing mobile crypto app developers today, her approach to smart wallets, and her ambition to create the Vercel for mobile crypto devs. It's always fun getting to meet a dynamic and relentless founder as Viv, especially at such an early stage in the company's journey. Her persistence and enthusiasm are inspiring. I hope you enjoy the show.
