Very cool, glad to see people tackling Ethereum UX! Your project seems similar to the Burner Wallet by Austin Griffith: https://github.com/austintgriffith/burner-wallet

Assuming you've seen that project, how does Hedgehog compare?

Do you have recommendations on handling the initial funding of a wallet, especially for your target market of non-technical users? (after they have the wallet, how do they obtain ETH or other tokens to get started?)

We haven't seen that before, looks cool! The approach may be similar, but we packaged Hedgehog as a standalone / documented library to be consumed directly by developers. In looking briefly I wasn't able to ascertain how the private key is stored / propagated between devices in his model so it's hard to comment more precisely.

The approach we've taken at Audius on initial funding is to avoid funding the wallet entirely - we use EIP-712 signatures combined with a trustless transaction relay service that pays gas / submits EIP-712 signed transactions on-chain on behalf of users. In this way, the user wallet never holds any tokens but is still used to secure access to their account. We'll be open-sourcing our contracts and infrastructure code soon, but here's a good public example of this model in action: https://github.com/hellobloom/core/tree/master/contracts

That said, other folks may decide to use Hedgehog differently - perhaps you integrate with something like Wyre (https://www.sendwyre.com/) to help users fund their wallet client-side without knowing that crypto is there.

Very, very excited to see you open source the EIP-712 trustless transaction relay setup. Any ETA on that?

Probably late summer / early Fall! Want to make sure the developer experience is high-quality at time of open-sourcing, but we're testing now / onboarding artists in a private beta.

Fair enough. Any thoughts on how your trustless relay setup compares to the Gas Station Network Alliance?

Very similar from a meta-transaction standpoint, but ours is simple and centralized (albeit trustless due to the tx signing model). This is much cooler!
