An audited zcashd wallet alternative: zecd Application Security Assessment by Zellic
Zecd is Zcash wallet server supporting Ironwood, with opt-in transparent (t-address) support - exposed through bitcoind's RPC dialect for developer ease of use. It uses the same method names, response shapes, auth, and error codes as Bitcoin Core, so that many existing Bitcoin RPC clients can use Zcash with little or no changes.
Documentation for zecd is available on the project website: zecd.org
- Stateless: all funds are recoverable from a seed phrase.
- Transparent, Ironwood, Orchard, and Sapling support. (including T-to-T)
- Connects directly to Zebra or Zakura with no indexer required.
- Large gap limits are supported (millions of unfunded transparent addresses).
- Built for dev and LLM productivity, speaking the familiar Bitcoind RPC
- Proven in production on Overpay.com since January 2026, open sourced in June.
This project is intentionally not backwards-compatible with zcashd. Instead it is compatible with
other librustzcash-powered wallets. To migrate funds from zcashd to zecd, the only supported path
is to send everything on-chain to addresses generated by zecd's getnewaddress.
It is not recommended to ever share seed phrases between apps. However by design, if something goes badly wrong with zecd, its seed phrases can be entered into any other librustzcash wallet to access funds.
zecd is a light client, for quick scalability. It syncs compact blocks in the background and never speaks P2P or indexes the chain itself. It connects to a self-hosted Zcash full node - a local zebra or Zakura over JSON-RPC.
All zecd funds are recoverable from the seed phrase - shielded funds unconditionally, transparent funds within the configured gap limit (see Transparent support). Importing private keys per-address is not supported; all addresses derive from the wallet seed.
