The iCoin hardware wallet is a cold storage device that securely holds private keys and signs digital currency transactions. It is the most secure way to construct a digital currency transaction. The iCoin hardware wallet has no network connectivity, so it can never directly connect to the internet or any blockchain.

Air Gap is a method of communicating information between two devices using cameras and QR codes. This allows one of the devices to remain ‘cold,’ with no network connectivity.

Hold the power button down for 3 seconds, then release. The gold iCoin logo should display on screen. If your wallet still does not power on, it may not be sufficiently charged. Remove the charger and USB-C cord provided in your wallet box, plug it into an active socket, and insert the USB-C cord into the base of the wallet. If your wallet is completely dead, it may take some time for an initial charge to occur. Once the wallet has been charging for some time (20 minutes,) quickly press and release the power button on the side of the wallet. A battery icon will display, followed by a percentage measurement of the battery’s current charge. Leave the wallet plugged in until the desired level of charge has been achieved, hold the power button down for 3 seconds, then release.

Your printer is shipped with thermal tape over the battery pins. Take off the back cover, remove the battery, and peel the thermal tape off the metal pins. Your printer may need to be charged. The charging cable is located next to the printer in the bundle box.

Recommended Thermal Paper: o Paper Width = 2.25 inches (58 mm) o Roll Length = 85 feet o Roll Diameter = 1 5/8 inches, or < = 50 mm o Paper thickness 0.06 – 0.08 mm

The Mobile App functions as the hardware wallet’s blockchain gateway, using Air Gap technology to relay and receive information to and from the hardware wallet. Since the iCoin hardware wallet has no network connectivity, it can never connect to a blockchain.

Your 24-word seed phrase is the root of all your private keys. Because iCoin uses the BIP 39 HD standard, your 24-word seed phrase generated on the iCoin hardware wallet can regenerate your keys on any wallet that supports the BIP 39 standard.

If you still have access to your iCoin Hardware Wallet and know your pin, you can go into your wallet’s settings and display or print your seed phrase. If you have lost your seed phrase and your hardware wallet, your funds will not be able to be recovered.

You have 4 attempts to enter your correct pin on the hardware wallet. After the 4th incorrect pin attempt the wallet will wipe its entire contents. If you have your 24-word seed phrase you can restore your wallet and accounts.

Restoring on the iCoin Wallet is very easy, as long as you have your 24-word seed phrase that was generated on the iCoin Wallet. Simply initialize the Wallet, create a 4-digit pin, then a name for your wallet. Next you will be asked if you would like to ‘Create new wallet’ or ‘Restore existing wallet.’ Select ‘Restore existing wallet.’ You will then have the option to scan the QR code of your seed phrase printed from your iCoin Printer, or manually type in the words using the Wallet’s touchscreen. Once your wallet is restored you can begin to recreate accounts, which can be seen under the iCoin Tutorial video ‘Create Accounts.’ The accounts you generate will be identical to the accounts previously generated. Automatic account regeneration is a feature on the iCoin roadmap. Since we now employ an optional Bluetooth connection between the iCoin Wallet & the iCoin Mobile App, this feature will be coming soon.

iCoin recommends transferring any funds from another wallet to a new address on the iCoin wallet, that way your private keys have never been on another device. iCoin’s wallet uses a specific hardened derivation path to generate keys. We do not check all derivation paths because the wallet is cold and not network connected. At this time we do not allow users to choose derivation paths. iCoin has enabled an optional Bluetooth connection between the iCoin Wallet and the iCoin Mobile App, making automatic account restoration a feature on the iCoin roadmap.

If network congestion is high, fees begin to rise. Transactions set with lower fees can be stuck in a pending state for some time, and may eventually be cancelled. On the transaction send page, use the fee slider to prioritize how much time you need for a transaction to process.

Pending Transactions can be viewed on an account’s page on the iCoin Mobile App under ‘Transaction History.’ Pending Transactions will be labeled ‘Pending,’ and will not be reflected in the Account’s Balance until the transaction is completed by the network.

If a User has pending sent transactions, the amount 'available' to send will be the User's account balance minus pending amounts.

Bitcoin transactions are constructed using an input, or multiple inputs. If a User has 1 input that equals 10.0 BTC, and this User wants to send 3.0 BTC to a bitcoin address, the entire input of 10.0 BTC is required to construct that transaction, and the User’s 7.0 BTC in change will be returned to the From address. Even though the User only wants to transfer 3.0 BTC, inputs cannot be broken down into smaller inputs. If the User tries to send another BTC transfer from that account while a previous transaction pends, the number of bitcoin ‘available' to spend will be 0.0 BTC. The User has no inputs to spend. Once the pending transfer clears, the User’s remaining 7.0 BTC will reflect as the account’s new BTC balance, and the User will have 7.0 BTC ‘available' to spend. Use the Fee Slider to adjust your transfer speed when constructing a transaction.

Stablecoins (ERC 20) & NFTs (ERC 721) tokens operate on the Ethereum network and require gas, or a fee, to transact on the network. Gas must be paid in native Ethereum (ETH), so your ERC address must be funded with native Ethereum. Simply send Ethereum to the address that has the Stablecoin or NFT you would like to transact.

Stored in a cool dark place, thermal paper can last a very long time. Keep your printed materials in secure locations.
