Obvious Smart Wallets with Himanshu Retarekar & Jebu Ittiachen
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.
