Huallet

Huallet is the self-custodial wallet of Chihuahua Chain. Hold, send, stake, swap and vote on HUAHUA and the whole Cosmos ecosystem, with your keys encrypted on your phone. Your keys, your phone

• Create a wallet (12 or 24 words, with verification) or import a recovery phrase or private key
• Secrets encrypted with AES-256-GCM, key derived from your password (PBKDF2-SHA256, 600,000 iterations)
• Optional fingerprint or face unlock: the password is kept by the phone's secure hardware (Android Keystore) and released only after a biometric check
• Screenshots blocked, no cloud backup of wallet data, auto-lock
• The recovery phrase is shown only after your password or biometrics
• Ledger hardware wallets over Bluetooth (Nano X, Stax, Flex) or a USB (OTG) cable, with the Cosmos app: keys never leave the device

Everything Cosmos

• Portfolio across chains: available, staked, rewards, unbonding
• Staking: stake, unstake, redelegate, claim rewards
• Swap on HuahuaSwap, Chihuahua's native DEX, and on Osmosis with the best route from the Osmosis router
• IBC transfers, channels verified on-chain before sending
• Governance: proposals, live tally, vote
• Chihuahua, Cosmos Hub, Osmosis, Juno and Celestia built in; add any chain from the Cosmos chain registry

Pay and get paid

• Scan an address or payment request QR code (in-app scanner, no Google services)
• Tap to pay over NFC: the receiver's phone shares a payment request, the payer's phone reads it. Only the request goes over NFC, never keys or signatures
• Tap a QR code to show it full screen at full brightness

Every transaction is shown in full before you sign. No analytics, no ads, no trackers. Network connections:

• Public Cosmos RPC/REST endpoints of your chains
• CoinGecko for fiat prices: on by default, can be turned off in Settings. Only token IDs are sent, never your address
• raw.githubusercontent.com for Cosmos chain registry data (asset lists, the chains you add, IBC channels) and token icons; chains.cosmos.directory for the list of chains you can add
• sqs.osmosis.zone for Osmosis swap quotes and raw.githubusercontent.com for the Osmosis asset list, only on the Osmosis swap tab

The icons of the built-in tokens are bundled in the app.
