4 Ways to Make On-Chain Transfers Without Internet

One challenge that still exists is the reliance on the internet to make on-chain transfers. In this article, we’ll explore various methods that enable individuals to perform on-chain transactions without the need for an internet connection.

These methods offer practical solutions for scenarios where internet access is limited or unavailable.

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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:

  1. 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.
  2. Transaction Creation: Using the Blockstream software, you create your transaction offline, including the recipient’s address and the transaction amount.
  3. 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.
  4. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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:

  1. 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.
  2. Offline Wallets: Users on the mesh network can utilize offline wallets to create and sign transactions without an internet connection.
  3. 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.
  4. Blockchain Broadcasting: The nodes with internet access can then broadcast the transactions to the blockchain, ensuring they are recorded on-chain.


In a world where Internet access is not ubiquitous, the ability to make on-chain cryptocurrency transfers without relying on the Internet is invaluable. Various methods, including SMS-based transactions, satellite technology, QR codes, and mesh networks, offer practical solutions for users seeking to engage with cryptocurrencies offline.

These methods enhance the accessibility and resilience of cryptocurrency transactions, making them suitable for a broader range of use cases, from remote areas with limited connectivity to disaster-stricken regions with disrupted internet access.
