On-chain Bitcoin competition entries are on-chain Bitcoin transactions — and Muun Wallet is designed to make every Bitcoin user comfortable with both on-chain and Lightning payments from a single non-custodial interface. For Muun users, sending BTC on-chain requires no extra setup beyond what they already have: the on-chain address Muun generates is self-custodied, the key belongs to the holder, and a standard send to any on-chain destination places the transaction on the Bitcoin blockchain under the Muun address. Bitok Arena's analysis of Muun's model for on-chain competition covers what makes Muun different and what Muun users need to know before their first competitive entry.
A wallet that handles Lightning and on-chain from one place does not split the Bitcoin practice into two separate tools. It simplifies it. The address stays the holder's regardless of which layer is used — on-chain sends go out from that address as standard Bitcoin mainnet transactions, and the Lightning capability does not interfere with on-chain competition participation in any way.
The relevant property for on-chain competition is simple: Muun is a self-custodial wallet, and the on-chain Bitcoin address it generates is fully controlled by the holder. The Lightning capability is an additional feature that does not interfere with on-chain transactions. When BTC is sent from Muun to any on-chain destination, the transaction goes out as a standard Bitcoin mainnet send and is recorded on the blockchain under the Muun address.
What Makes Muun Different From Standard Wallets
Most Bitcoin wallets handle either on-chain payments or Lightning Network payments, with separate tools required to use both. Muun takes a different approach: it gives every user a single Bitcoin address that works for both payment types simultaneously. When a Lightning payment is received, Muun uses a submarine swap in the background to settle the transaction on-chain — funds arrive at the on-chain address regardless of how they were sent. This design is fully non-custodial. Muun generates the private key on the user's device and never transmits it to any server.
Bitok Arena reviewed Muun Wallet's technical architecture to characterize its self-custody properties and competition compatibility.
Custody model — non-custodial. Private key generated on device at setup. 12-word recovery phrase provided; Muun does not retain a copy. Recovery is independent of the Muun app and company.
Lightning / on-chain unification — Muun uses submarine swaps to settle Lightning receipts on-chain. One address, one balance, one app. The on-chain address receives BTC directly regardless of whether the originating payment was Lightning or on-chain.
On-chain send behavior — sends to standard Bitcoin addresses broadcast as standard Bitcoin mainnet transactions from the user's address. Indistinguishable from any other self-custody wallet send.
Competition compatibility — Muun addresses are standard bc1q format. They appear on competition leaderboards identically to any other self-custody wallet address. No special handling required.
The recovery phrase at setup gives independent access to funds regardless of whether the Muun app or company exists. The address is the holder's in the same way a hardware wallet address is theirs — the key is on their device, and only they can sign transactions from it. This is the property that matters for on-chain competition: the address belongs to the participant, the prize routes directly to it on-chain, and no intermediary is involved between the blockchain confirmation and the participant's wallet.
Sending From Muun to an On-Chain Destination
Open the Muun app and tap Send. Paste the on-chain destination address — Muun automatically detects that it is a standard Bitcoin address and processes it as an on-chain send. Enter the amount and confirm the transaction. Muun shows the network fee before confirmation; select a fee level appropriate for the timing requirements of the specific destination. Under normal network conditions, a medium fee setting confirms within 20 to 40 minutes. Every confirmed transaction from the Muun address accumulates to the on-chain record for that address.
Bitok Arena reviewed the Muun send workflow to identify any behavior specific to Muun that on-chain competition participants should account for.
Automatic payment type detection — Muun detects whether a pasted address is a Lightning invoice or standard Bitcoin address. Standard mainnet addresses (bc1, 1, or 3 prefix) are processed as on-chain sends automatically; no manual layer selection required.
Fee transparency — Muun displays the network fee before confirmation, with options for different fee levels. Higher fees confirm faster under congestion.
Multiple sends — Muun supports multiple sends from the same address during a round cycle. Each confirmed transaction adds to the on-chain record; no Muun-specific frequency limitation exists beyond standard confirmation requirements.
Receiving on-chain — incoming transactions (including prizes) appear in the Muun balance as standard on-chain receives. No withdrawal step required; the BTC is in the wallet immediately on confirmation.
To add to a position during a round, open Muun, tap Send again, and use the same destination address. Every confirmed transaction from the Muun address during the window accumulates to the cumulative total for that address on the on-chain record. Prizes paid to a top-position address arrive in the Muun wallet as a standard on-chain receive. The BTC appears in the balance, and the recovery phrase ensures access to it regardless of any app or service state.
Lightning vs the Base Layer
Muun's value proposition is handling both Lightning (for speed and everyday payment efficiency) and on-chain (for permanence and base-layer transactions) from one non-custodial interface. On-chain competition uses the base layer because that is where verifiable, irreversible results are recorded. A competition entry is a real Bitcoin mainnet transaction — permanent, public, and independently verifiable. The Lightning Network, while fast and efficient, does not produce the same permanent on-chain record that competition leaderboards derive their data from.
Lightning gives speed for everyday payments. The base layer gives permanence for competition records and prize payouts. Muun handles both from one wallet. On-chain competition uses the base layer because that is where the verifiable, irreversible result lives — permanently recorded on the Bitcoin blockchain, readable by anyone with a block explorer, and not subject to revision by any platform or intermediary.
Muun users have a complete Bitcoin stack in one non-custodial app — Lightning for everyday payment efficiency, on-chain for the base-layer transactions that competition participation requires. The on-chain address is the competition identity, the ranking address, and the prize destination. Bitok Arena's analysis of Muun for on-chain competition finds no compatibility issues, no special workflow requirements, and no limitations that distinguish Muun participation from any other non-custodial wallet. The wallet is compatible. The address belongs to the holder. The rest is a standard Bitcoin on-chain send.
Bitok Arena's review of Muun Wallet confirms it is fully non-custodial: private key generated on device at setup, never stored by Muun, with recovery independent of the app and company. Sends to standard Bitcoin addresses broadcast as standard Bitcoin mainnet transactions, indistinguishable from any other self-custody wallet; competition entries, position accumulation, and prize receipts all work identically. Muun's unified address model serves both Lightning and on-chain from a single address that belongs entirely to whoever holds the recovery phrase.
