Penumbra Labs will also be at the Shielding Summit to give a product demo as well as connect with fellow builders looking to learn more about utilising Penumbra

Catch Penumbra's founder, Henry, at both Parallel Society Congress (psc.logos.co) and Shielding Summit (shieldingsummit.org)

To test it out, install the extension, use the Discord faucet to request testnet tokens, and let us know what's broken in the web-ext-feedback channel!

And, because the extension performs local indexing, most RPC requests are processed locally, so the demands on fullnodes are lightweight.

To support decentralization, our goal is that any `pd` node should be able to serve a frontend, out-of-the-box, with no configuration.

This design means that spending or viewing keys never leave the extension, so users can grant viewing permissions to web interfaces and revoke them later, and see exactly what they're authorizing before they approve.

These services are first-class interfaces used throughout the Penumbra ecosystem.

For the web, we provide them through a browser extension, using a custom transport object allowing frontend code to make GRPC requests to the extension the same way it would call a remote server.

The Custody service handles auth requests, allowing the user to review and authorize a TransactionPlan describing a proposed transaction, and returning a bundle of auth data needed to build the transaction.

The View service is a personal indexer, providing read access to all private data visible to a given wallet. It scans for relevant transactions, downloads them, and decrypts and indexes them locally.

Our approach to solving this problem is to provide a "local RPC" in a browser extension that restores the programming model for frontends for transparent chains.

We define two GRPC services, for "read" and "write":
