# FOUR TOKEN | ecosystem native multi-chain asset


Logo

A multi-chain non-dilutive asset, a technical component that enables 4thTech tokenization with staking and transaction discounts.

# Smart Contract

FOUR's smart contract design implements:

  • the ERC-20 interface that can be used with any Ethereum native blockchain wallet (ERC-20 standard allows FOUR to integrate with most of EVM compatible Layer 2's or Side Chain's and various DeFi application platforms);
  • embedded TTS interface (i.e. token teleportation-service), that enables wallet accounts to use FOUR natively as gas;
  • MTO (i.e. multiple-transfer option), settlement service that conserves blockchain network transactions and bundles signed multiple transactions together and settles them on the blockchain as one transaction.

# Economy

The 4thTech economy utilises FOUR as a unit of value on the web platform that enables token holders with the right to access applications and earn services discounts by staking FOUR in the ecosystem.

# Utility

4thTech token (i.e. FOUR) is the ecosystem native utility token, used as the primary means to enable services, incentivize participants. It represents a unit of value with the right to stake and access to services discounts while enabling ecosystem tokenization.

# History

Developed and deployed in 2018, FOUR acted as one of the technical components needed for the 4thTech ecosystem tokenization on Ethereum network, combining three technical utility features:

  • embedded TTS interface (i.e. token teleportation-service);
  • MTO (i.e. multiple-transfer option);
  • GAS feature. Due to Ethereum gas prices increase, the ERC-20 FOUR had to evolve to become a multiverse asset occupying the space of multi-chains, while being used as the primary means to enable 4thTech services, services discounts, incentivize participants and provide a default mechanism to store and exchange value.

# A multi-blockchain asset

Cross-chain interoperability of ERC-20 FOUR with other blockchains essentially increases the decentralisation of liquidity and unlocks a universe of possibilities for further development. The users instantly benefit from lower fees and the native DeFi economy of the bridged blockchain. With an unchanged total and circulating token supply, the FOUR ERC-20 exists on its native Ethereum blockchain, while a wrapped synthetic version exists on the bridged blockchains.

# A multiverse asset on Binance Smart Chain

logo BSC

Cross-chain interoperability of FOUR tokens opens a multiverse of new possibilities. We are looking at new innovative data exchange tokenization models, instant data exchange transactions with 1000x lower TX fees and much more. At the same time, FOUR ERC-20 exists on its native Ethereum blockchain, while a wrapped synthetic BEP-20 FOUR exists on the Binance Smart chain.

  1. What is Binance Smart Chain?

    Binance Smart Chain or short BSC is the second blockchain launched by Binance. Binance originally launched the Binance Chain to facilitate Binance Coin (i.e BNB) and transactions on their decentralized Binance exchange (i.e. Binance DEX). Focusing on reliability, transaction speeds and trade efficiency, the original Binance Chain does not support smart contracts. To enable smart contracts and programmable compatibility the Binance Smart Chain was released. The BSC also features compatibility with the Ethereum Virtual Machine. Both chains are completely independent and exist in parallel serving specific functions.

  2. What is the BEP-20?

    The BEP-20 is a Binance Smart Chain token standard specifically designed for decentralized finance (i.e. Defi) and decentralized applications on the BSC.

  3. FOUR as BEP-20 wrapped token

    The FOUR tokens were originally deployed as ERC-20 on the Ethereum chain. On the Binance Smart Chain, the FOUR tokens appear as wrapped equivalents, a synthetic version of the original asset.

    According to Binance Academy, a wrapped token is a cryptocurrency token pegged to the value of another crypto. Itโ€™s called a wrapped token because the original asset is put in a wrapper, a kind of digital vault that allows the wrapped version to be created on another blockchain. The benefit of the wrapped tokens is the ability to circumvent the limitation of the non-native blockchain assets. A wrapped BEP-20 FOUR (i.e. Binance Smart Chain token standard) is a tokenized pegged version of the ERC-20 FOUR (i.e. Ethereum token standard) on the Binance Smart Chain.

  4. How does it work?

    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 donโ€™t change.

Cross-chain interoperability of FOUR tokens opens a multiverse of new possibilities. The bridging of ERC-20 FOUR to SPL FOUR token will increase project recognition, liquidity and unlock a universe of possibilities such as:

  • extreme transaction speeds with 1000x lower TX fees;
  • access to the Solana DeFi economy;
  • new innovative tokenization models;
  • instant information exchange.
  1. Solana Blockchain

    Solana is the next generation censorship-resistant blockchain with extreme transaction speeds and low cost, therefore perfect for DeFi and other high-speed blockchain applications. Solana leverages Proof of History and several other breakthrough innovations to allow the network to scale at the rate of Mooreโ€™s Law (Solana.com, May 2021).

  2. What is the SPL token?

    According to Solana, the SPL Token program is the token standard of the Solana blockchain. Similar to ERC20 tokens on the Ethereum network, SPL Tokens are designed for DeFi applications. There is already a cross-chain bridge called Wormhole that allows users to lock ERC20 tokens in an Ethereum smart contract and mint corresponding SPL Tokens on Solana.

  3. FOUR as SPL wrapped token

    The FOUR tokens were originally deployed as ERC-20 on the Ethereum network. While the FOUR ERC-20 exists on its native Ethereum blockchain, a wrapped synthetic equivalent version of the original asset SPL FOUR exists on the Solana blockchain.

  4. How does it work?

    When sending ERC-20 FOUR to the Solana blockchain, 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 Ethereum, while the equivalent amount of SPL FOUR is minted on Solana. When the SPL FOUR needs to be bridged back to ERC-20 FOUR, the smart contract puts in an SPL 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 doesnโ€™t change.

  5. Ethereum ERC-20 to Solana SPL token bridge

    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).

  8. Solana blockchain brings new possibilities

    The SPL FOUR brings various advantages to the 4thTech ecosystem and its users. For example, the Serum DEX FOUR/SOL market will bring new liquidity and enable lower fee trading, while users will benefit from countless Serum DEX features and its on-chain order book, which is the first of its kind. The bridging of FOUR to Solana blockchain is just a first step to the multiverse multi-chain 4thTech interoperability. The close to real-time Solana transaction speeds enable 4thTech to innovate further. A solution is currently being developed that will offer new communication possibilities that were not possible before.

# A multiverse asset on Polygon Blockchain

logo SPL

Cross-chain interoperability of FOUR tokens opens a multiverse of new possibilities. The bridging of ERC-20 FOUR to POLYGON FOUR token will increase project recognition, liquidity and unlock a universe of possibilities such as:

  • higher transaction speeds with lower TX fees;
  • access to the Polygon DeFi economy;
  • new innovative tokenization models.
  1. Polygon Blockchain

    Also known as Matic Network, Polygon improves the functionality of the Ethereum blockchain by extremely increasing its network scalability and transaction speed. Polygon uses its own Proof-of-Stake (PoS) blockchain and Commit Chain connectivity to help scale the Ethereum network, and seeks to solve inefficiencies that may hinder widespread adoption of blockchain technology. source (opens new window)

    According to Polygon, Polygon is an Ethereum Layer 2 protocol and a framework for building and connecting Ethereum-compatible blockchain networks. Aggregating scalable solutions on Ethereum supporting a multi-chain Ethereum ecosystem. Currently, it enables 500+ DApps to scale their performance, while combining the best of Ethereum and sovereign blockchains into a full-fledged multi-chain system. source (opens new window)

    As explained by Decrypt source (opens new window), Polygon uses a variety of technologies to achieve this expanded vision, these include;

    • POS Chain: Polygonโ€™s main chain is an Ethereum sidechain known as the Matic POS Chain, which adds a proof-of-stake (POS) security layer to blockchains launched on Polygon.
    • Plasma Chains: Polygon makes use of a scaling technology known as Plasma to move assets between the root chain and child chains via Plasma bridges.
    • ZK-rollups: An alternative scaling solution used to bundle a large number of transfers off-chain into a single transaction, using zero-knowledge proofs for the final public record on the Ethereum main chain.
    • Optimistic rollups: A solution that runs on top of Ethereum to facilitate near-instant transactions through the use of โ€œfraud proofsโ€.
  2. POLYGON PoS FOUR token

    According to Polygon, the ERC-20 Polygon token program is the same token standard as on Ethereum. Cross-chain bridge allows users to lock Ethereum ERC-20 tokens in an Ethereum smart contract and mint corresponding POLYGON ERC-20 tokens on Polygon.

  3. Ethereum /Polygon Cross-Chain Bridge

    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.

The exchange (i.e., swap) of the FOUR token is available on the designated exchanges and de-fi protocols and it is not a public offering of equity or debt and, consequently, does not fall under securities or any prospectus regulation. The FOUR tokens are not securities as defined under applicable laws. Therefore, the FOUR tokens have not been registered with any competent regulator. The exchange (i.e., swap) of the FOUR tokens is unregulated. Changes to legislation in the most relevant jurisdictions in the world are closely monitored. Appropriate actions will be undertaken to act accordingly if regulatory changes impact the four-token exchange and operations.
