Explore the Namada Wallet, a secure and user-friendly tool for managing keys and addresses on the Namada network. Learn about its features, including asset-agnostic shielded transfers, low transaction fees, and compatibility with hardware wallets like Ledger.

What is Namada?

Namada is a proof-of-stake Layer 1 blockchain designed for interchain, asset-agnostic privacy. As the first fractal instance of Anoma, Namada focuses on enabling shielded transfers for various assets—both fungible and non-fungible—regardless of their originating platform, such as Ethereum or IBC-compatible chains. This means users can transfer assets like ETH, DAI, ATOM, or OSMO privately, with minimal transaction latency and near-zero fees.

To make these privacy-preserving transfers more accessible, Namada is vertically integrated and will soon feature user-friendly interfaces.

Unique Features of Namada

Asset-Agnostic Shielded Transfers

Namada facilitates the transfer of any fungible and non-fungible tokens with privacy akin to Zcash, including native and non-native tokens. This is achieved through the deployment of advanced zk-SNARKs technology.

Shared Shielded Set

A notable feature of Namada is its shared shielded set. This means that a shielded transfer involving an Ethereum NFT is indistinguishable from a transfer of ATOM or NAM. The MASP (Multi-Asset Shielded Pool), an upgraded version of Zcash’s Sapling circuit, allows all assets to share the same shielded set, ensuring that privacy guarantees are not fragmented and are independent of the transaction volume of a particular asset.

Fast ZKP Generation on Edge Devices

Namada’s vertical integration allows users to interact with the protocol and send shielded transfers via browser applications. This is facilitated by fast Zero-Knowledge Proof (ZKP) generation, even on edge devices.

Low Transaction Latency and Near-Zero Fees

Thanks to rapid proof generation and modern Byzantine Fault Tolerant (BFT) consensus, Namada supports transaction speeds comparable to Visa, with finality. Similar to Anoma, Namada scales through fractal instances.

IBC-Compatible and Trustless Ethereum Bridge

Namada is compatible with any fast-finality chain that supports IBC. For Ethereum interoperability, Namada employs a custom trustless Ethereum bridge designed for maximum safety, including flow controls for all bridge connections and treating faulty Ethereum transfers as slashable offenses. To ensure liveness across the Ethereum bridge and enhance user experience, incentivized relaying to Ethereum is incorporated.

Privacy as a Public Good

The Namada protocol incentivizes users holding shielded assets, contributing to the shared shielded set. The latest MASP circuit update includes the novel Convert Circuit, making the shielded set a non-exclusive, anti-rivalrous public good. The more people use shielded transfers, the better the privacy guarantees for each individual.

Introducing the Namada Wallet

The Namada wallet provides a user interface for storing and managing keys and addresses. Technically, keys are large integers with significance on an elliptic curve, and the wallet “remembers” these numbers for you. Keys are the building blocks for accounts on Namada, coming in pairs (secret and public keys) that derive the account address.

Keys come in the form of pairs (of secret and public key), and can be used to derive the account address (first 40 chars of the SHA256 hash of the public key).

Wallet Options on Namada

File System Wallet: The default storage location is .namada/{chain_id}/wallet.toml, where keys are securely encrypted. Users can change the base directory path or store unencrypted key pairs using specific flags. Passwords can be provided via stdin, environment variables, or a file.

Currently, the Namada client offers multiple ways to provide the password:

1. Stdin: The client will prompt you to enter the password.
2. Env variable: You can export an environment variable called NAMADA_WALLET_PASSWORD with the actual password as its value.
3. File: You can export an environment variable called NAMADA_WALLET_PASSWORD_FILE with the path to a file containing the password as its value.

Web Wallet: Available in most browser extension web stores once Namada is on mainnet.

Hardware Wallet: The Namada web wallet extension is compatible with Ledger hardware. Users can connect their Ledger devices to manage keys securely.

Connecting Your Ledger

1. Open the Namada web extension.
2. Click on the “Connect Ledger” button under settings.
3. Set an alias for the account controlled by Ledger.
4. Choose to connect via USB or HID.
5. Confirm the connection on your Ledger device.
6. The extension will display the account address controlled by Ledger.
7. Use Ledger to sign transactions.

Conclusion

The Namada wallet is a crucial tool within the Namada network, offering secure key and address management with various storage options and hardware wallet compatibility. As Namada advances, it continues to enable seamless interactions and empower users in multichain privacy and asset-agnostic transfers.
