Tendermint KMS
Tendermint KMS is a Key Management Service (KMS) that allows separating key management from Tendermint nodes. In addition it provides other advantages such as:
- Improved security and risk management policies
- Unified API and support for various HSM (hardware security modules)
- Double signing protection (software or hardware based)
It is recommended that the KMS service runs in a separate physical hosts.
You will need the following prerequisites:
✅ Rust (stable; 1.56+): https://rustup.rs/
✅ C compiler: e.g. gcc, clang
✅ pkg-config
✅ libusb (1.0+). Install instructions for common platforms
✅ Debian/Ubuntu
apt install libusb-1.0-0-dev
✅ RedHat/CentOS
yum install libusb1-devel
✅ macOS (Homebrew)
brew install libusb

We are ready to install KMS. There are 2 ways to do this: compile from source or install with Rusts cargo-install. We’ll use the first option.
The following example adds
--features=ledger
to enable Ledger support. tmkms
can be compiled directly from the git repository source code, using the following commands:gh repo clone iqlusioninc/tmkms && cd tmkms
[...]
cargo build --release --features=ledger
If successful, it will produce the
tmkms
executable located at: ./target/release/tmkms
.A KMS can be configured using the following HSMs
