Coldbrook · self-custody wallet

Your keys,
already in your pocket.

Coldbrook routes, signs, and settles from the phone you already carry. No exchange holds your units between taps — the wallet does, and only you hold the keys.

Coldbrook · four networks

Four networks, one wallet.

Move where the units already are. No bridging tab, no separate app for the network that happens to be cheaper today.

Coldbrook · how it works

Three steps between a tap and a settled send.

Walk the line. Every stop shows what the wallet is doing with your send at that moment, not what a server somewhere claims it did.

  1. Route
  2. Sign
  3. Settle

Every send picks its own network

Coldbrook checks the fee and the wait on all four networks and proposes the one that fits — you can always override it.
