Muun Wallet is a self-custody Bitcoin wallet that handles both on-chain transactions and Lightning payments through a single interface. It is one of the few wallets designed to abstract away the difference between the two layers — a user can receive a Lightning invoice and a Bitcoin mainnet payment to the same wallet without managing channels or understanding the technical distinction. For most Bitcoin use cases, that abstraction is a genuine usability improvement. For Bitok Arena competition, it creates a specific confusion to understand: the address you use to enter must be an on-chain Bitcoin mainnet address, and the way Muun sends those on-chain transactions has an implication for how Bitok Arena records the competing identity.
Muun Wallet's architecture uses submarine swaps — sending a Lightning payment executes an on-chain transaction that the recipient's node converts into a channel payment. Muun's receive address is therefore a standard on-chain Bitcoin address, and BTC sent there arrives as a standard mainnet transaction. That on-chain receive address is the Muun feature relevant to Bitok Arena. The Lightning interface is not.
The Bitok Arena-relevant part of Muun Wallet is the on-chain Bitcoin receive address — the address displayed in Muun's Receive section that starts with bc1q or bc1p. Sending BTC from that Muun address to the Bitok Arena master wallet creates a standard Bitcoin mainnet transaction that the leaderboard reads and records under the sending address. The Lightning interface in Muun is not relevant to Bitok Arena entries because Bitok Arena does not accept Lightning payments — it reads from the Bitcoin mainnet blockchain, and Lightning payments do not produce the on-chain transaction format that the leaderboard recognizes.
How Muun Wallet Handles Bitcoin and Lightning
Muun's design philosophy is to present a single wallet that works for both Bitcoin mainnet and Lightning without requiring the user to manage channels or understand the technical distinction between layers. When a Muun user wants to pay a Lightning invoice, Muun executes a submarine swap — a trustless exchange protocol where an on-chain payment from the Muun address is exchanged for a Lightning channel payment that settles the invoice. The result from the user's perspective is that they enter a Lightning invoice and BTC leaves their wallet; the underlying mechanism is an on-chain transaction that Muun's infrastructure converts to a Lightning payment.
Muun Wallet's components and their relevance to Bitok Arena:
On-chain receive address — a bc1q or bc1p mainnet address that receives standard on-chain BTC; this is the address to send from when entering Bitok Arena; the leaderboard records it as the competing identity.
Lightning receive (BOLT11) — Muun generates Lightning invoices settled via submarine swaps; Lightning receipts reach the wallet balance but do not produce the on-chain TXID format that Bitok Arena's leaderboard reads.
Sending interface — accepts both bc1q addresses and Lightning invoices (lnbc) as destinations; for Bitok Arena entries, always use the Bitok Arena master wallet's bc1q address, not a Lightning invoice.
Fee structure — network fee shown before broadcast; review it before confirming the Bitok Arena entry to ensure the net amount sent matches the intended competition commitment.
The distinction between Muun's on-chain and Lightning interfaces matters for the Bitok Arena TXID that the leaderboard uses to record the entry. A standard on-chain Bitcoin mainnet transaction from Muun to the master wallet produces a TXID that appears on the Bitcoin blockchain and is recognized by Bitok Arena's leaderboard system after the required confirmation count. A Lightning payment through Muun's submarine swap infrastructure also produces on-chain transactions as part of the swap mechanism, but those transactions are routed through Muun's own infrastructure addresses — not directly from the user's address to the master wallet — which means the leaderboard address attribution may not match the user's personal Muun address.
The Right Muun Send for Bitok Arena
The correct way to send a Bitok Arena entry from Muun Wallet is to open the Send interface, paste the Bitok Arena master wallet's bc1q address as the destination, enter the competition entry amount, review the fee, and confirm. Muun recognizes the bc1q destination as a Bitcoin mainnet address and routes the transaction directly on-chain from the Muun wallet's address to the master wallet. The resulting transaction has a TXID that appears on the Bitcoin blockchain under the Muun wallet's on-chain address as the sender — and that address is what appears on the Bitok Arena leaderboard as the competing identity.
What makes a Muun send produce a correct Bitok Arena leaderboard entry versus an unrecognized one:
Address format determines routing — pasting the Bitok Arena master wallet bc1q address causes Muun to auto-detect Bitcoin mainnet and route on-chain; entering a Lightning invoice (lnbc...) instead routes through Muun's swap infrastructure under a different address, which does not produce a leaderboard entry under the competitor's own address.
BTC amount vs currency display — Muun accepts input in BTC or local currency; when entering in local currency, the BTC equivalent displayed before confirmation is the amount that actually broadcasts; currency conversion rounding can reduce the committed amount below the intended entry size if not reviewed before confirming.
A TXID check on any block explorer after broadcast verifies the master wallet appears as recipient — confirming the entry routed to Bitcoin mainnet correctly.
Muun Wallet's prize receipt works correctly as well. After a winning Bitok Arena round, the prize is sent as a standard Bitcoin mainnet transaction to the address that competed. If the competing address was Muun's on-chain bc1q address, the prize arrives in the Muun wallet's Bitcoin balance as an incoming on-chain transaction. Muun displays it in the transaction history alongside any other incoming BTC. The prize does not require a separate withdrawal action — it arrives the same way any on-chain Bitcoin payment arrives at a Muun address.
When to Use Muun vs Other Wallets for Bitok Arena
Muun Wallet's strength is its unified Bitcoin and Lightning interface — ideal for users who regularly make both types of payments and want a single wallet that handles both without manual channel management. For Bitok Arena competition specifically, the relevant feature is the on-chain send capability, which Muun provides cleanly. Users who compete in Bitok Arena exclusively and do not need Lightning payments would find a dedicated Bitcoin mainnet wallet like BlueWallet or Sparrow equally functional with potentially more transparent fee control. For users who already use Muun for Lightning payments and want to add Bitok Arena competition without managing a separate wallet, Muun's on-chain send handles it without switching apps.
Muun Wallet is a capable self-custody Bitcoin wallet for Bitok Arena entries when used correctly — meaning on-chain send to the bc1q master wallet address, not a Lightning invoice. The Lightning side of Muun is irrelevant to the competition. The on-chain Bitcoin side is what produces the transaction that the Bitok Arena leaderboard reads, records, and counts toward the competing address's position.
The fundamental rule that applies to Muun and to every other wallet in the Bitok Arena context is the same: the competing address must be a Bitcoin mainnet address whose private keys you hold, and the entry transaction must be a standard Bitcoin mainnet transfer to the master wallet's bc1q address. Muun satisfies both conditions when its on-chain send interface is used. The Lightning features of Muun — while useful for other Bitcoin payments — are simply irrelevant to a competition that runs entirely on the Bitcoin mainnet blockchain.
Muun's Lightning features are excellent for Lightning payments — and completely irrelevant to Bitok Arena, which reads from the Bitcoin mainnet blockchain. Use Muun's on-chain Send interface, paste the Bitok Arena master wallet bc1q address, confirm the transaction, and your competing address appears on the leaderboard after the required on-chain confirmations. Enter today's round and let Muun's on-chain side do what Bitok Arena needs.
