This guide walks you through setting up your Aqua wallet for daily Lightning use, from installation to conducting real-world transactions. Whether you're new to Bitcoin or an experienced user, you'll learn how to leverage Aqua’s powerful features for efficient, secure, and hassle-free crypto management.
Understanding the Aqua Wallet
Aqua is a non-custodial mobile wallet designed for users who want frictionless access to both the Lightning and Liquid Networks. Available on iOS and Android, it simplifies advanced Bitcoin functionality without sacrificing security or control. Unlike traditional wallets that require manual channel management, Aqua handles everything in the background—making it one of the most user-friendly lightning-capable wallets on the market.
Key Features and Benefits
Aqua stands out by automating complex processes such as channel balancing and asset conversion. Instead of managing open channels or worrying about inbound liquidity, users simply send and receive payments. Behind the scenes, Aqua converts between Lightning and L-BTC automatically, ensuring smooth transaction flow.
- Seamless Layer 2 Integration: Conduct Lightning-fast transactions without holding Lightning Bitcoin directly.
- Self-Custody Security: You retain full control of your private keys and funds at all times.
- Multi-Network Support: Access Bitcoin mainnet, Lightning Network, and Liquid Network within a single interface.

Supported Networks and Currencies
Aqua supports a focused but powerful set of networks tailored for efficiency and privacy:
- Bitcoin Mainnet: For standard on-chain transactions.
- Lightning Network: Enables instant, low-fee micropayments.
- Liquid Network: Offers faster confirmations, enhanced privacy, and support for digital assets like L-BTC and USDT.
In terms of currencies:
- Native BTC (Bitcoin)
- L-BTC (1:1 pegged to BTC on the Liquid Network)
- USDT (Tether) issued on Ethereum and Tron, automatically bridged to Liquid
This design allows users to enjoy the benefits of stablecoins while leveraging Bitcoin’s security through Liquid’s federated sidechain model.
Security Measures
As a self-custodial wallet, Aqua ensures that only you have access to your funds. During setup, you’ll generate a 12-word recovery phrase—this is your sole means of recovering your wallet if your device is lost or damaged.
Critical security practices include:
- Writing down your seed phrase on paper and storing it offline
- Enabling biometric authentication (fingerprint or face ID)
- Setting a strong PIN code
While Aqua provides these protective layers, remember: no third party can recover your wallet if you lose your seed phrase. Responsibility rests entirely with you.
Step-by-Step Setup Guide
Download and Installation
Begin by downloading Aqua Wallet from official sources:
- iOS: App Store
- Android: Google Play Store
Search for “Aqua Wallet” and install the app. Avoid third-party download links to prevent counterfeit versions.
Once installed, open the app to begin the setup process.
Creating Your Wallet
On first launch, select "Create New Wallet". The app will generate your unique Bitcoin wallet in about 30 seconds.
After creation, you’ll be prompted to back up your 12-word recovery phrase. Tap “View Seed Phrase,” write it down carefully in order, and store it securely. Never share this phrase or store it digitally.
You’ll then return to the main dashboard, where you’ll see two account types:
- Savings Account: Stores native Bitcoin (on-chain)
- Spending Account: Holds L-BTC for fast Layer 2 transactions (Lightning & Liquid)

Configuring Lightning Transactions
Aqua simplifies Lightning usage by abstracting away technical complexities. Here's how it works:
- When receiving a Lightning payment, the incoming sats are automatically swapped into L-BTC and stored in your spending account.
- When sending via Lightning, your L-BTC is swapped back into Lightning funds during transmission.
To receive:
- Tap "Receive"
- Select "Lightning"
- Enter an amount (in BTC or USD)
- Generate an invoice or QR code to share
To send:
- Tap "Send"
- Choose "Lightning"
- Paste an invoice or scan a QR code
- Confirm the transaction
No need to monitor channels or liquidity—Aqua handles it all automatically.
Managing Daily Lightning Transactions
Generating Invoices for Payments
Need someone to pay you? Use the invoice feature:
- Open the app and tap Receive > Lightning
- Set the amount
- Share the generated QR code or BOLT11 invoice via messaging apps
This is ideal for freelancers, content creators, or anyone accepting small payments online.
Paying Invoices Quickly and Securely
Sending coffee money or repaying a friend? Just:
- Tap Send > Lightning
- Scan their QR code or paste their invoice
- Approve the swap from L-BTC
Transactions settle in seconds with minimal fees—even for international transfers.
Understanding Fees
While Lightning is known for ultra-low fees, Aqua applies a small service fee for each automatic swap between Lightning and L-BTC. This covers backend operational costs and ensures reliability.
Note: For very small transactions (e.g., under $1), fees may appear relatively high compared to pure Lightning wallets. However, this trade-off brings significant advantages:
- No channel management
- Always-ready outbound liquidity
- Enhanced security via L-BTC storage
For regular users prioritizing convenience and self-custody, Aqua offers excellent value.
