Nym Technologies used Devcon 8 in India to unveil a mixnet SDK that lets wallets and decentralized applications route browser traffic through its 5-hop mixnet, aiming to strip network metadata such as IP addresses and timing patterns before it leaves the user's device.
The announcement, dated November 5, 2026, packages work Nym has already been deploying in wallet integrations for a broader developer audience.
What the SDK includes
An SDK is a set of prebuilt components developers can add to their own applications rather than building from scratch. Nym's kit is built on open-source Rust components, with a headline crate called nym-smolmix that can stand in for the standard network sockets an app uses to communicate with the internet.
The SDK supports HTTP(S) and gRPC traffic, covering standard web requests made by most dapps as well as a common protocol for app-to-server communication. Users do not need to install a separate VPN, because the privacy layer lives inside the wallet or dapp itself.
Nym says its mixnet runs on more than 700 independent node operators, spreading trust across a large group rather than a single company.
Existing wallet integrations
The SDK is less a debut than a promotion. Under a Zcash Community Grant in September 2026, Nym completed wallet integrations that are now live in production versions of two Zcash wallets, Zingo and Zkool. Edge Wallet followed with a native integration announced in March 2026.
Exploratory work goes back further: Nym began testing compatibility with WalletConnect, the connection standard many users rely on to link wallets with dapps, starting in 2023.
The Devcon stage was a deliberate choice. Nym is emphasizing that the SDK can support Ethereum-based wallets and is positioning itself within the Ethereum community's ongoing debate about protecting users at the network level.
Why metadata matters
Network metadata is the quieter privacy problem. Even if a transaction is shielded, the request that broadcasts it carries an IP address and a timestamp.
Nym CEO Harry Halpin has argued that the mixnet's protections complement on-chain shielding rather than replace it. He pointed to Zcash's zk-proofs and Ethereum RPC protections as the on-chain half, with the mixnet covering the network half. Zero-knowledge proofs can obscure transaction contents, but they cannot stop a server from logging who connected to it.
Practical questions remain
For wallet developers, adding network-level privacy previously meant asking users to install and configure something extra. The production deployments in Zingo, Zkool and Edge are proof that the mixnet runs in shipping software rather than only in a demo, giving Ethereum wallet teams something concrete to evaluate.
The open questions are practical ones. Routing traffic through five hops could introduce tradeoffs that wallet teams will need to weigh against the privacy gains, and the community discussion so far has centered on technical applications rather than adoption figures.
