How to exchange files or data from wallet to wallet;

  • Step 1: Download your 4thTech Google Chrome or Mozilla Firefox wallet
  • Step 2: Create and backup your wallet. To create your wallet, set up your password.
  • Step 3: Log into the 4thTech web platform
  • Step 4: Top-up your wallet with gas money ( the 4thTech platform currently supports Ethereum, Polkadot Edgeware, Tolar HashNet and Solana)

Note:

💡 Use FOUR Staking to obtain up to a 50% discount on service fees. If you want to find out more about FOUR Staking, click the link.

There are 3 TIERS available:

  • tier 1 10k FOUR staked enables 10% discount
  • tier 2 20k FOUR staked enables 20% discount
  • tier 3 50k FOUR staked enables 50% discount

Disclaimer:

💡 The number of FOUR tokens in tiers 1-3 is variable due to market conditions and/or price fluctuations.

  • Step 5: In order to send data files to friends and colleagues you will need to know your wallet address and the receiver's wallet address. Your wallet address works like your phone number or email address. It is uniquely yours!

Note:

💡 For example, let’s say the Polkadot Edgeware network is your blockchain of choice. Your Polkadot Edgeware wallet account is used for sending or receiving any type of data files. It works similarly to email attachments, but with one main difference. Exchanging data files via blockchain is 100% secure and private.

Note:

💡 4thTech platform currently supports Ethereum, Polkadot Edgeware, Tolar HashNet and Solana.

  • Step 6: Tap on the Send data tab, fill in the request form, attach the file and press Send.

Note:

💡 4thTech currently supports up to 20Mb of data file size.

  • Step 7: If you send a file, you can follow the transaction in the blockchain explorer of the chosen network by pressing the transaction Explorer link. If you receive a file, you can check it in your Received data tab.

Note:

💡 Check the file authenticity by clicking on the submenu Details. If the Checksum Match is green, then the received file is authentic. Remember to download the received files to your computer as library storage is limited up to 7 days. After 7 days, files will be deleted.

How to exchange short messages from FOURwaL SOL address to FOURwaL SOL address?

Note:

💡 Due to the required fast transaction speed, short messaging is currently available only on the Solana blockchain

  • Step 1: Download and set up your wallet (i.e. FOURwaL) and log into the 4thTech web platform (opens new window).
  • Step 2: Exchange Solana wallet addresses with friends, coworkers or family members
  • Step 3: Fund your 4thTech Solana wallet with SOL tokens to provide gas
  • Step 4: Stake FOUR tokens to enable the chat function (available in web platform 3.0)

Note:

💡 Tier 3 FOUR STAKING will be required in web platform 3.0 to enable the short messaging service.

  • Step 5: Tap on the Instant messaging tab to connect with a friend, coworker or family member by pasting his/her Solana 4thTech wallet address and start chatting.

Note:

💡 Currently, only Solana TX cost is being charged in $SOL with a possibility of a small protocol service fee to be added in the future. With the 4thTech Web Platform 3.0 update coming in 2022, the right to FOURim access will be enabled with $FOUR token staking. Overall there are currently three cost variants to be considered in the messaging process:

  1. Initialization of a conversation between two wallets usually takes more time to be established as five accounts needs to be created (we are adding a progress window in future updates). Testing produced the following TX cost: 0,006845503 SOL “Hi 😄”

  2. When the conversation is established between two wallets, sending and receiving messages takes less time averaging between 1 and 5 seconds. Testing sending a short message produced the following TX cost: 0,000039503 SOL “ooo 😃”

Bridging ERC-20 FOUR from Ethereum to Binance Smart Chain BEP-20 FOUR using OmniBridge and xDai Chain

When sending ERC-20 FOUR to Binance Smart Chain, the cross-blockchain bridge is needed. The Bridge enables the cross-chain token bridging in both directions. The smart contract locks the ERC-20 FOUR sent from the Ethereum, while the equivalent amount of FOUR BEP-20 is minted on BSC. When the BEP-20 FOUR needs to be bridged back to ERC-20 FOUR, the smart contract puts in a BEP-20 FOUR burn request to the Bridge, and the ERC-20 FOUR are released from the reserves. This process ensures that the total and circulating token supply don’t change.

Ethereum ERC-20 FOUR to Solana SPL FOUR token Bridge Manual

The Solana Wormhole bridge enables ERC-20 FOUR to bridge to SPL FOUR available on the Solana blockchain. The Wormhole bridge uses decentralized cross-chain oracles (i.e. guardians) operated by a set of node operators that include top Solana validators and other ecosystem stakeholders whose incentives are strongly aligned with Solana and Serum (Solana.com, May 2021).

Ethereum ERC-20 FOUR to Polygon FOUR token Bridge Manual

The Polygon bridge enables ERC-20 FOUR to bridge to Polygon FOUR available on the Polygon blockchain. As FOUR token Multiverse is expanding, it is important to know how to use it. The first step is always the bridge. FOUR tokens have been integrated into the official Ethereum — Polygon cross-chain bridge, so ERC-20 FOUR token holders can now easily migrate between two universes.
