We are doing this already and plan to increase the investment over time. Stay tuned!


This is an excellent summary of our approach - thanks for writing it up :)


We did consider Flutter, but (1) we already had a very strong javascript talent base that we wanted to leverage; (2) at the time when we made the decision, Flutter was still relatively early in its lifecycle.

That said, we've spent a lot of time talking with teams using Flutter and we think it's awesome!


Could you say which teams you were talking to? Curious about companies adopting Flutter and why over other solutions.


Mostly teams within Google that have had success with it.


Hi all - I support all Retail engineering at Coinbase and was one of the folks who helped shepherd this change through from inception to rollout.

I'm happy to answer any questions that folks have - just thread here, and I'll either answer or pull in our team to give more detail.


What does your CI/CD look like? It took me a long time to fully flesh out a RN pipeline that was (mostly) completely automated. Are you leveraging Fastlane? Are you buliding both Android and iOS on OSX VMs? How do you deal with shipping canary versions and is that process also automated? Thanks!


We talked a good amount about this [here](https://twitter.com/dan_coff/status/1393599897119592456). We are using Fastlane. We are building iOS on OSX, but Android on more standard EC2 hardware. We ship canaries with every commit to master, fully automated.


Not really a question but more of a statement that Discover also transitioned from Native to React Native successfully and I believe they also didn't do a brownfield implementation. There was a presentation about this at React Chicago but I can't seem to find it.


So what is your native mobile engineering team doing now?


All of them were cross-trained to be React Native engineers. Many of them are now working full time in React-land doing product engineering and some of them are working on lower level native infrastructure. We saw very little attrition and have emerged as a stronger, unified client engineering group (across mobile and web).


Which native mobile engineering team?


The ones that were initially hired to work native Android / iOS?

We’re they down sized? Re trained? Etc. and so on. Can you speak about the process around this and so on. I understand you want to give a positive image externally here, but I’m more interested in what struggles occurred and how you resolved it / did not resolve it.


Sorry, I'm not the OP. I just tried to be funny. As in "there's probably no such team anymore".


Sup Jesse!


Hi!

I've personally been here for 3 years and love it. Tons of autonomy, lots of really challenging problems, and a super mission aligned employee group.

We're particularly interested in folks who are interested in building a world-class Javascript platform across React and React Native. Also, we just went fully remote-first (focus on US-remote hiring for now), so would love to hear from folks who are interested in that!

See all our open roles at Coinbase here: https://coinbase.com/careers

Tech Stack: Go, Ruby Rails, React (web), Swift (iOS), Kotlin & React Native (Android)

If you're interested in chatting more, feel free to shoot me an email at jpollak@coinbase.com. Looking forward to talking!

Hi all — head of engineering for the consumer product at Coinbase here (iOS, Android, coinbase.com).

Happy to answer any questions that people have — also, just wanted to make a plug that we're hiring. If you're interested in building an open financial system for the world, shoot me a note at jpollak@coinbase.com. Especially interested in iOS & Android engineers!


What will Coinbase do if there is a contentious hard-fork of the Ethereum chain and different USDC supporting exchanges decide to follow different forks?


In this case, the issuer of USDC, Circle, would be the one to decide which fork of Ethereum to support. It's not like USDC the ERC20 token is worth anything without Circle's backing.


This is a hard question. I don't have an answer for you, but if a situation like this arises, we'll be sure to clearly communicate our thought and decision process to our customers. Thanks for asking!


If you actually cared about an Open Financial System you would list Dai on Coinbase. Centralized stablecoins allowing issuers to freeze and blacklist is a step backwards not forwards.


What are your thoughts on MakerDao which uses the MKR and Dai tokens for decentralized collateral backed stablecoins called Dai?

Their implementation is happening a bit slower due to the novelties but it offers the MKR which is a profit incentive for proliferation, and may be more resilient than centralized stablecoins


Personal opinion, not the company: I think it's very cool. I've been watching them since they launched and have been impressed with their consistent progress. I love using it as an example of financial experimentation and success: they launched at the top of the bubble and have been able to keep stability even as crypto has gone through a massive crash! Pretty amazing.


Have you published the USDC contract to the network?


Anders Brownworth from Circle here - I just wanted to point out that https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb... is the proxy contract. (an address that won't change but who's source code doesn't contain the "meat" of the logic) That contract simply proxies calls to the current main FiatToken contract deployed at https://etherscan.io/address/0x0882477e7895bdc5cea7cb1552ed9... but if you want to see the official repository for the project, it is available from CENTRE on GitHub at https://github.com/centrehq/centre-tokens


Yes, you can see the contract here: https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb.... Thanks!



Hey there Jesse. Question for you: Will Coinbase Commerce also be integrating support for USDC? Thanks!


I can't comment for them on this one, sorry!
