Method 1: SMS-Based Transactions
One of the most accessible ways to perform on-chain transfers without Internet access is through SMS-based transactions. This method utilizes Short Message Service (SMS) technology to broadcast transactions to the blockchain. Here’s how it works:
- Wallet Setup: You’ll need a cryptocurrency wallet that supports SMS-based transactions. Services like CoinText and Coinapult offer such wallets. Create an account and link your phone number to it.
- Transaction Initiation: To initiate a transaction, you send a specific SMS command to the wallet service. This command typically includes the recipient’s wallet address, the amount you wish to send, and a secure PIN or verification code.
- Confirmation: After receiving your SMS, the wallet service processes the transaction and sends you a confirmation SMS. You’ll need to enter your PIN or verification code to confirm the transaction.
- Blockchain Recording: The wallet service then broadcasts the transaction to the blockchain, where it is recorded on-chain.
For example, you can use Samourai’s wallet and make BTC transactions without the internet.

Method 2: Satellite Transactions
For users in remote areas or during internet outages, satellite transactions offer a reliable and secure way to make on-chain transfers. Companies like Blockstream provide satellite-based services that enable users to interact with the Bitcoin blockchain via satellite signals. Here’s a brief overview:
- Hardware Setup: You’ll need a satellite receiver, a small dish, and a computer with the necessary software installed. Blockstream provides detailed instructions for setting up the hardware.
- Transaction Creation: Using the Blockstream software, you create your transaction offline, including the recipient’s address and the transaction amount.
- Broadcast via Satellite: When you’re ready to send the transaction, the satellite receiver broadcasts it to Blockstream’s network of satellites, which then relay the transaction to the Bitcoin network.
- Confirmation: Once the transaction is received by the Bitcoin network, it is confirmed and recorded on the blockchain.

Method 3: QR Codes and Offline Wallets
QR codes and offline wallets provide another offline option for making on-chain transfers. This method allows users to prepare transactions offline and then broadcast them when they regain internet access. Here’s how it works:
- Wallet Setup: Start by creating an offline wallet or using a paper wallet generator. These wallets are generated and stored completely offline, minimizing security risks.
- Transaction Preparation: With your offline wallet, prepare the transaction details, including the recipient’s address and the transaction amount. The transaction data is typically represented as a QR code.
- QR Code Storage: Save the QR code containing the transaction data on a physical medium like paper or a USB drive. Keep this medium secure.
- Broadcast the Transaction: When you have internet access, use a wallet software that allows you to scan the QR code and broadcast the transaction to the blockchain.

Method 4: Mesh Networks
Mesh networks offer a decentralized approach to enable on-chain transactions without relying on traditional Internet infrastructure. In a mesh network, users connect directly to nearby devices, creating a network that can transmit data without internet access. Here’s how it can work:
- Mesh Network Setup: In areas with limited or no internet access, communities can set up local mesh networks using readily available hardware like smartphones, routers, or specialized mesh network devices.
- Offline Wallets: Users on the mesh network can utilize offline wallets to create and sign transactions without an internet connection.
- Local Nodes: Some mesh networks may have nodes equipped with internet connectivity. Users can relay their offline transactions to these nodes for broadcasting to the blockchain.
- Blockchain Broadcasting: The nodes with internet access can then broadcast the transactions to the blockchain, ensuring they are recorded on-chain.
