haha extension recovery phrase wallet setup guide and main features
Haha wallet setup guide and user features
Download the official application exclusively from the Apple App Store or Google Play Store. After installation, select “Create a new vault.” Write down the 12 or 24-word recovery phrase on paper only–never store it digitally. This phrase is your sole fallback for asset recovery; losing it means permanent loss of access.
Enable biometric authentication (Face ID or fingerprint) immediately within the security settings. For daily transactions, configure a PIN code of 6 to 8 digits. Activate the “Transaction Signing” toggle to require manual approval for each transfer, preventing accidental or unauthorized outflows.
The interface supports multi-chain asset management, including Bitcoin, Ethereum, Solana, and BNB Smart Chain. Use the built-in swap function to exchange tokens across networks without leaving the app. The swap engine aggregates liquidity from 12 decentralized exchanges, displaying estimated slippage and fees before you confirm.
Integrated dApp browsing allows direct interaction with protocols like Uniswap, Aave, and OpenSea. Approve smart contracts individually per session, and revoke permissions through the “Connected Sites” dashboard. For recurring payments, the recurring send function supports daily, weekly, or monthly schedules with fixed or dynamic amounts.
Data privacy is enforced via client-side encryption; your keys never pass through external servers. For advanced users, the “Watch-Only” mode lets you monitor addresses without exposing private keys. All network fees are displayed in USD or the native token, with an option to set custom gas limits for Ethereum-based chains.
Haha Wallet Setup Guide and Main Features
Initiate the installation by downloading the official client directly from the repository’s release page on GitHub. Verify the SHA-256 checksum against the published hash to eliminate counterfeit versions. On the first launch, the application prompts you to generate a new vault; reject cloud-based recovery options for maximum sovereignty.
Secure your 12-word mnemonic on acid-free paper using a steel stamp. Store this plate in a fireproof safe; never photograph or type it.
Select the PRNG seed mode under the “Advanced” tab: use the hardware RNG option if your device supports Intel RDSEED, else fall back to system entropy but add 256 rounds of PBKDF2 manually.
Set a wallet-level passphrase (not the password) of at least 40 characters mixing Unicode symbols. This generates a completely distinct key tree–even if the mnemonic is exposed, coins remain locked without the passphrase.
For hardware security module integration, compile the package with the --enable-hsm flag. Connect a YubiKey 5 Series via USB and map the slot to the signing protocol. The client supports Ed25519, secp256k1, and post-quantum Falcon-512 keys simultaneously, selectable per transaction.
The core engine employs a UTXO model with atomic swap support across 12 chains natively. To initiate a cross-chain transfer, load the “CoinSwap” panel, input the destination address, and choose the liquidity pool with the tightest spread (indicated by a green marker). The system automatically splits large utxos into chunks of 0.01–0.05 BTC equivalents to optimize fee rates.
Batch transactions: Consolidate up to 200 inputs in a single output using the “Sweep Dust” function under the “Coins” menu. The algorithm selects inputs with a fee-to-value ratio below 0.5%.
CoinJoin rounds: Access the mixer via the “Privacy” tab; each round requires 5 participants minimum. Configure 3–10 hops, wit h a default delay of randomized 60–240 seconds between rounds to break timing correlation.
The “Watch-Only” mode imports xpub keys without private material. Enter the extended public key in Base58 format, then filter addresses by derivation path: m/84'/0'/0' for native SegWit, m/49'/0'/0' for nested SegWit. The index scans up to depth 50,000 automatically; adjust the gap limit under “Settings > Rescan” for legacy wallets.
For recurring payments, deploy the “CronTx” plugin from the built-in module store. Define trigger conditions in JSON: {"schedule": "0 0 * * MON", "max_fee": 0.0001, "outputs": [{"address": "bc1q...", "value": 0.005}]}. The service broadcasts only when the mempool median fee drops below your threshold.
Network nodes default to eight outgoing connections over Tor v3. Force IPv4-only peers by appending -addnode=192.0.2.1 in the config file. Monitor peer latency via the terminal CLI command cli getpeerinfo | jq '.[] | addr, pingtime'; disconnect any node with ping above 500 ms to reduce block propagation delay. Enable “Block Filter” (BIP 157/158) to lighten bandwidth–only 1.2 MB per day for full verification instead of downloading entire blocks.
Step-by-Step Initial Account Registration Process
Begin by downloading the official application from the verified developer’s page on your device’s app store. Verify the publisher name matches the project’s documented core team. Ignore third-party links found in search results.
Open the software and tap “Create New Profile.” You will be prompted to choose between a standard seed phrase backup and an advanced social recovery option. For maximum security, always select the seed phrase method, then write down the 12 or 24-word sequence on paper–never store it digitally.
After confirming your backup, the interface will require you to re-enter the phrase in the correct order as a verification step. This process ensures you have recorded it correctly before proceeding.
Set a strong local PIN code (minimum 6 digits). This code encrypts the data stored on your device. Unlike the recovery phrase, this PIN cannot reset your keys if lost.
Next, configure your security preferences:
Option
Action
Impact
Auto-lock timer
Set to 1 minute
Protects idle application
Biometric lock
Enable (Face ID / Fingerprint)
Adds layer of physical access control
Transaction signing
Require PIN for each action
Prevents accidental transfers
Finally, review the “Trusted Contacts” section. Add one or two recovery contacts only if you opt for social recovery. For a standard setup, skip this step entirely to reduce attack surface.
Your account is now active. The software will generate your public address automatically. Do not share your recovery phrase with any support agent or website. All subsequent functions–receiving funds, viewing balances, and signing–are now accessible from the main screen.
How to Generate and Secure Your Seed Phrase
Generate your seed phrase exclusively on a device that has never been connected to the internet. A brand-new, factory-reset computer or a dedicated hardware security module is the only acceptable environment. Download the official software directly from the project’s GitHub repository, verify the checksum, and run it offline. The software will present 12 or 24 random words; do not alter or select them yourself.
Write the sequence down using a hard pencil on acid-free, fireproof paper. Do not use a printer, screenshot, or any digital storage medium. Photocopies degrade and phone cameras expose the phrase to cloud backups. Store the paper in a fireproof safe rated for at least 60 minutes of direct flame. A secondary copy in a separate geographic location (e.g., a bank safety deposit box) is mandatory for disaster recovery.
Never enter your seed phrase into any website, app, or software outside the original generation tool. Phishing sites replicate legitimate interfaces. Verify the domain with a DNS lookup tool before typing a single letter. If an application requests your seed phrase for “backup” or “restore” purposes, immediately close it and scan for malware. Legitimate software should never ask for an existing seed phrase unless you are performing a fresh recovery on a known, offline device.
Divide your 24-word list into three 8-word segments. Encrypt each segment separately using a different algorithm (e.g., AES-256 for one, ChaCha20 for another). Store each encrypted segment on a separate medium: a steel plate, a laminated card, and a USB drive with hardware encryption. Without all three segments and their respective decryption keys, an attacker cannot reconstruct the full phrase. This obfuscation thwarts single-point-of-failure theft.
Implement a passphrase (25th word) for additional entropy. This extra string–a random mix of uppercase, lowercase, digits, and symbols–must be at least 30 characters long. Never store it alongside the seed phrase. Memorize it or entrust it to a single executor in a sealed envelope. Without this passphrase, the seed phrase alone cannot derive the private keys, even if compromised physically.
Test your recovery process by importing the seed phrase into a temporary offline environment. Attempt to sign a transaction or derive an address. Confirm that the generated public addresses match your recorded ones. Perform this test annually or after any hardware failure. A single mistyped word from a faulty backup renders all assets inaccessible. Use the BIP39 standard to verify word indices against a local lookup table.
Destroy all original generation logs, temporary files, and browser caches immediately after the phrase is written down. Overwrite the disk with random data three times or physically destroy it if you generated on a dedicated machine. Treat the seed phrase as radioactive material: if a human eye sees it, assume it is burned. Any exposure to cameras, mirrors, or reflective surfaces during generation necessitates repeating the entire process on a new device.
