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!

Have you published the USDC contract to the network?

  I believe this is it: https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb....

  Yes, you can see the contract here: https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb.... Thanks!

  Anders Brownworth from Circle here - I just wanted to point out that https://etherscan.io/address/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48#code 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/0x0882477e7895bdc5cea7cb1552ed914ab157fe56#code 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 https://github.com/centrehq/centre-tokens

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?
- omarchowdhury 8y ago
  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.
- jessepollak 8y ago
  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!
omarchowdhury 8y ago
Hey there Jesse. Question for you: Will Coinbase Commerce also be integrating support for USDC? Thanks!
- jessepollak 8y ago
  I can't comment for them on this one, sorry!

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.
