# Handshake Developer Call 5/28/2020

## News

### Bob Wallet Release Candidate

Bob Wallet is one of the more important pieces of the Handshake ecosystem and a new release candidate was recently cut. If users could test and give feedback it would be greatly appreciated.

https://github.com/kyokan/bob-wallet/releases/tag/v0.2.9-rc.1

### New `hsd` Node RPC `getdnssecproof`

This RPC will build and optionally verify the DNSSEC proof that is required to claim a name. Useful for users that want to claim their name and test whether or not their DNSSEC proof is set up properly.

[Docs](https://hsd-dev.org/api-docs/#getdnssecproof)

### Bugfix: Allow Bids With Bids/Blinds of 0

Previously an assertion would prevent the wallet HTTP endpoints from creating bid outputs with values or blinds of value 0.

### New `hsd` HTTP Endpoint `GET /header`

Users can call `GET /header/:heightOrHash` to fetch a block header by height of by hash. This is useful for SPV nodes that do not index the full blocks.
