Description

@Delgado74

Hi team,

I’d like to propose the inclusion of a new tutorial focused on Phoenix Wallet, developed by ACINQ.

🔎 Why Phoenix?
Phoenix is one of the easiest self-custodial Lightning wallets available today. It offers a clean interface, strong connectivity, and does not require users to manage channels manually. It’s ideal for onboarding users into sovereign Bitcoin Lightning use without technical complexity.

✅ Key Advantages:

Full self-custody with automatic channel management

Simple backup: just the 12-word seed phrase — no need to worry about channel backups

Stable and reliable in mobile and low-connectivity environments

Clear interface and user-friendly experience

⚠️ Important aspects the tutorial will explain:

Lightning fee model: Each Lightning payment incurs a fee of 4 sats + 0.4 %, which may affect users making frequent or small payments.

Fees when receiving for the first time: The first Lightning payment triggers a channel opening (splicing), which incurs an on-chain fee deducted from the received amount.

Channel splicing explained: Phoenix uses splicing to increase channel capacity without closing and reopening channels, keeping everything seamless and automatic.

No separate “on-chain wallet” view: Unlike other Lightning nodes or wallets, Phoenix does not show a separate on-chain balance. All funds are held within Lightning channels, and while users can withdraw to an on-chain address if needed, this is not recommended as a regular practice, and this point will be clearly addressed in the tutorial.

Why Phoenix is useful in Cuba: It allows users to retain full control of their funds without relying on custodians or complex infrastructure. Even while operating over Lightning, users maintain their private keys until they choose to move funds to an on-chain cold wallet if desired.

📚 Goal of the tutorial:
To provide a clear, step-by-step guide for Cuban and Latin American users who want to:

Use Lightning in a simple and secure way with full self-custody

Retain full control of their BTC

Understand how Phoenix works: fees, receiving, sending, backup, and how to interact with the on-chain network when necessary

Looking forward to hearing your thoughts and to see if this proposal aligns with the project goals. If approved, I’ll be happy to start drafting the tutorial.

Thanks!
