Your XBT.
Your keys.
Your phone.
Wren is a simple, self-custody wallet for XBT, the coin of the BLAKE2b fork chain. It is being built in the open for iPhone and Android.
What Wren is being built to do
Claim your XBT safely
Held BTC before the split at block 961,632? You may also hold XBT. Wren moves it with a hardware signer, so your BTC seed never touches a phone.
Always the right chain
Every signature is invalid on the BTC chain by design. Wren uses
its own xbt: payment links and refuses BTC servers.
Private by default
Tor is built in and on from the start. Use the project server or connect your own node.
XBT is not BTC. They are separate coins on separate chains.
Built in the open
Every line of Wren is public, so anyone can check the code that holds their money. Outside bitcoin developers review the plan before code is written, again when signing works, and a formal security review comes before any release.
