ZODL has begun launching its proprietary wallet servers, isolating user IPs from wallet requests through OHTTP.

BlockBeats news, November 9 - Zcash mobile wallet Zodl's official account posted that ZODL has begun gradually rolling out its self-operated wallet infrastructure to prevent user IP addresses from being linked to wallet requests. ZODL stated that previously, Zcash wallets needed to connect to light wallet servers to sync the blockchain and forward transactions, and the server operators could see the IP addresses of connecting parties and request-related information; even if the transactions themselves were shielded, metadata such as IP addresses and connection times could still expose user activity.

ZODL stated that it has partnered with Cloudflare and Fastly to integrate the IETF standard Oblivious HTTP (OHTTP). Wallets no longer connect directly to ZODL servers, but instead send requests through independent relays operated by Fastly or Cloudflare: the relays can see user IPs but cannot see the still-encrypted wallet request contents; ZODL processes the requests but cannot see users' original IPs. ZODL stated that no single party possesses both pieces of information simultaneously, and its infrastructure is designed so that ZODL itself cannot directly link wallet requests to user IPs.

ZODL also stated that previously, Zodl relied on light wallet servers maintained by community operators, which remain an important part of the Zcash ecosystem; after self-operation, it can directly handle server issues, scale with business growth, and develop new features and integrations more independently. ZODL views this as the first step of the third pillar "Run" in its "Save, Spend, Run" vision, and stated that it will subsequently make more infrastructure available for users to operate themselves without relying on ZODL or other providers. The infrastructure will be gradually rolled out over the coming week, with monitoring of Android and iOS performance, and F-Droid and Github versions are planned for release later this week. Users only need to update to Zodl 3.20.0 with no other action required beyond downloading the update, and can also view or switch connected servers in advanced settings.
