Fluidkey is graduating to beta with

We have generated over 40k privacy-preserving addresses so far and are opening up access to our beta for 48h

Congrats to the
@UmbraCash
team! 🚀👏 We’re excited to see Umbra’s work on
#stealth
address protocols & tooling getting support.
Stealth addresses will be a key component of Fluidkey and the Umbra team has done a fantastic job in pushing stealth address standards forward
Last month, the
@ethereum
Foundation funded
@ScopeLift
—the team behind Umbra—to advance a stealth address standardization effort for the EVM. Thank you EF!

1. the infrastructure to generate new stealth addresses for our users in real time is currently managed by Fluidkey, this is similar to other ENS offchain resolvers like Coinbase’s and Uniswap’s uni.eth

just label it :)
two simple ways to use our newly released labels:
1. group incoming txs by category - e.g. salary, personal, clients
2. label each tx with a keyword - e.g. salary-apr-24, name-of-client
this allows you to select where to send outgoing txs from and stay organized

The first part here is correct - this is the same trust assumption you have when using other ENS offchain resolvers like CB or Uniswap
Regarding the second part - you can recover and generate new stealth addresses without us at any time using our open source library & the

Every new transaction gets sent to a new smart account with a different address - all of these smart accounts can then be controlled with your Fluidkey account but they are not connected onchain, which gives you privacy

the onchain part of the resolver verifies that the returned response has been signed by Fluidkey's keys but it currently doesn't verify the stealth address itself - we're thinking about ways to do this without reducing privacy

hi there, we are still working on support for Safe as a signer, for now you can connect with an EOA or Privy which will then be the owner of your stealth Safe smart accounts inside Fluidkey
