Thanks for correcting me. I agree with you. I should not have used the word "decentralized". Chainsfr is non-custodian with minimum trust, not decentralized.

And we didn't call ourselves decentralized on our website.

Understood. Let me try to clarify here.

Google has one of the best user authorization management system. Chainsfr is only allowed for certain access to Chainsfr related data. Most of the requests are directly from users' own devices, not our server. And every access will need users' permission.

A Google account is required because Chainsfr is deeply integrated with Google ecosystem. The service benefits greatly from Google in many ways, like OAuth, key storage, cross-platform syncing, account security, smooth user experience, and many more.

In Chainsfr, we tried to find a balance between keeping the benefits of decentralization and building a product that is easy to use. Bitcoin core would have the best privacy but also be impossible for mass adoption. Having different options for people to choose might be the ultimate way to solve the problem.

Great question! Let me explain.

Google Drive is one of the most important components of Chainsfr non-custodial architecture.

To keep Chainsfr to be a decentralized service required minimum trust, we need a database that only users can access to store their payment secret, aka, the security answers. We cannot store this sensitive data on our own server, otherwise, Chainsfr would be a centralized service.

Now Google drive comes along. The permission of Google drive can make sure that only users can access this data using Chainsfr frontend. And our server also does not have the permission to access this sensitive data. And all data in Google drive have been encrypted, which means Google cannot access it either.

This is Lucas from the Ventureum team in Toronto🍁. I am here to introduce our new product "Chainsfr" at https://chainsfr.com ➡️.

Chainsfr is a non-custodial open-source payment service, integrated with Google, which lets you send cryptocurrency by email to anyone from your favorite crypto wallets -- like Ledger, Coinbase and more. Our goal is to provide you a similar experience as Venmo or Interac e-Transfer if you live in Canada when sending cryptocurrencies.
