BlueWallet is a Bitcoin-only open-source mobile wallet with one of the most complete feature sets available on a phone. It supports on-chain Bitcoin transactions and the Lightning Network in the same interface, provides manual fee control down to sat/vByte, and is built by a team with a long track record in the Bitcoin-only development space. For Bitok Arena participants who want the transaction control of a desktop wallet in a mobile form factor, BlueWallet is the best available option.
BlueWallet is Bitcoin-only by design — there is no ETH, no multi-chain support, and no token marketplace. This is not a limitation for Bitok Arena participants; it is the correct scope. The wallet does one thing: manages Bitcoin on the most battle-tested network available. The fee control, address management, and transaction detail it provides reflect that single-minded focus.
Setup: Install, Secure, and Configure
Download BlueWallet from the official source — App Store for iOS, Google Play for Android, or bluewallet.io directly. Verify the developer listing (BlueWallet Services s.r.o.) before installing. Create a new wallet within the app and select Bitcoin (not Lightning) for an on-chain competition wallet. BlueWallet generates a 12-word seed phrase. Write it down in order on paper, verify it using the in-app confirmation step, and store it offline. The same seed phrase security practices that apply to every non-custodial wallet apply here.
BlueWallet defaults to Native SegWit for new Bitcoin wallets. Verify this: tap the wallet name to open settings and confirm the wallet type shows as HD SegWit (P2WPKH). The receive address will begin with "bc1q". If a legacy address type was selected at setup, create a new wallet with the correct type — the address format matters for fee efficiency in competition entries.
This fee control is the feature that distinguishes BlueWallet from simpler mobile wallets. For time-sensitive round entries, knowing the exact sat/vByte rate can determine whether a transaction confirms in the next block or the next few.
Fund and Send to Bitok Arena
Open the wallet, tap Receive, and copy the bc1q address. Provide this to an exchange for the withdrawal. Once the Bitcoin network confirms the incoming transaction, the balance appears in BlueWallet. To send to Bitok Arena: tap Send, paste the master wallet address from the leaderboard, verify it character by character, enter the amount, set the fee using the custom rate option, and confirm.
BlueWallet displays the transaction as pending while it awaits network confirmation. After three confirmations, your address appears on the Bitok Arena leaderboard. The same address can receive prize winnings directly if you finish in the top three — no additional steps, no claim process. The prize is an incoming on-chain transaction to the same address you competed from.
BlueWallet provides Electrum-level fee control in the wallet most appropriate for mobile-first participants. The Bitcoin-only scope, open-source codebase, and detailed transaction management make it the choice for participants who want maximum transparency about every transaction they send. The leaderboard sees the same thing it sees from any other wallet: a confirmed Bitcoin transaction from a bc1q address. What BlueWallet adds is confidence that the fee was right and the address was verified.
One practical note for BlueWallet users: the app supports connecting to a personal Electrum server or a public server for broadcasting transactions. The default public server works correctly for most participants. For those who run a personal Bitcoin node, connecting BlueWallet to it provides additional privacy — the transaction is broadcast from your own node rather than a third-party server.
Bitcoin-only, open-source, manual fee control, Native SegWit default. BlueWallet is the mobile wallet for participants who want desktop-level transaction precision in their pocket. The competition requires a confirmed transaction with the right fee. BlueWallet gives you every tool to ensure that is exactly what you send.
