Namada

(Namada Apps) (Libraries)

Overview

Namada is a Proof-of-Stake L1 for multichain asset-agnostic data protection. Namada uses CometBFT consensus and enables multi-asset shielded transfers for any native or non-native asset. Namada features full IBC protocol support, a modern proof-of-stake system with cubic slashing, and a stake-weighted on-chain governance mechanism. Users of Namada's MASP (Multi-Asset Shielded Pool) are rewarded for their contributions to the shielded set in the form of native protocol tokens. A multi-asset shielded transfer wallet is provided in order to facilitate safe user interaction with the protocol.

Warning

Here lay dragons: this codebase is still experimental, try at your own risk!

💾 Installing

There is a single command to build and install Namada executables from source (the node, the client and the wallet). This command will also verify that a compatible version of CometBFT is available and if not, attempt to install it. Note that currently at least 16GB RAM is needed to build from source.

make install

After installation, the main namada executable will be available on path.

To find how to use it, check out the User Guide section of the docs.

For more detailed instructions and more install options, see the Install section of the User Guide.

⚙️ Development

# Build the provided validity predicate and transaction wasm modules
make build-wasm-scripts-docker

Before submitting a PR, please make sure to run the following

# Format the code
make fmt

# Lint the code
make clippy

🧾 Logging

To change the log level, set NAMADA_LOG environment variable to one of:

• error
• warn
• info
• debug
• trace

The default is set to info for all the modules, except for CometBFT ABCI, which has a lot of debug logging.

For more fine-grained logging levels settings, please refer to the tracing subscriber docs for more information.

To switch on logging in tests that use #[test] macro from test_log::test, use RUST_LOG with e.g. RUST_LOG=info cargo test -- --nocapture.
