Risk warning

Trading cryptocurrencies involves significant risk and can result in your capital loss. You should not invest more than you can afford to lose and you should ensure that you fully understand the risks involved. Before trading, please take into consideration your level of experience, and purchase objectives, and seek independent financial advice if necessary. It is your responsibility to ascertain whether you are permitted to use cryptocurrencies based on the legal requirements in your country of residence. Purchasing crypto assets are not covered by the Financial Ombudsman Service or subject to protection under the Financial Services Compensation Scheme. Please read the security information.


Cryptocurrencies are extremely volatile. Bitcoin went from a penny to $32, then it crashed 94% to $2. Then it went from $2 to $270 then crashed 81%. Then it went from $51 to $1200 then crashed 86%. Then it went from $164 to $20,000, then crashed 84%. Then it went from $3,150 to $14,000 and crashed 72%. And that's the most liquid, oldest cryptocurrency in the world. Nearly every crypto currency drops 85% to 95% at some point. Some get back up and make new all time highs.

Disclaimer - Website/dAPP

The rex.io website and the app.rex.io dApp have been voluntarily created by the crypto community to allow an easier interaction with the "REX" Smart Contracts.

No guarantee is given for the functionality and availability of the rex.io website or the app.rex.io web3 dApp. Please find the full disclaimer and the Privacy Policy at the bottom of this page.

Disclaimer - "REX" Smart Contracts

"REX" is the name of a public and fully decentralized software running on a blockchain, that consists of a set of smart contracts, as described in its technical description, the whitepaper.

The software is immutable and will continue running on the blockchain, as long as the blockchain exists. The software does not have an owner or admin. The software is not more than immutable compiled bytecode sitting on the BSC network, that can do nothing on its own but sit there. People can run the code if they want to, or not.


The source code of the software was written by "Thomas Rex", who chose to remain anonymous. The source code has been fully published so that everyone can read, understand, analyze and test it themselves. There is no such thing as 100% certainty that the blockchain and smart contracts will work flawlessly forever. In order to achieve the highest possible probability that the software works exactly according to the white paper, it has been independently audited by three market-leading auditing firms. Everyone may use the software at will, taking into account the above risk warning.


"REX" is not a legal entity, a company, enterprise, institution or other organization.

Consequently, there are no managers, no employees and no authorized representatives. Accordingly, any person who does anything related to “REX”, such as talking about, discussing, promoting, creating videos, posts or other content about REX, does not represent “REX” but rather expresses their own personal ideas and views.


For anyone using blockchain technology, cryptocurrencies and Smart Contracts, make sure to fully understand what you are doing and the associated risks -

Please read and understand and stick to the security information.

DeFi / KYC

REX is a Decentralized Finance ("DeFi") protocol.

REX users are able to interact with the Smart Contracts when they bought BNB tokens (to pay for the network's transaction fees) and BUSD tokens (to participate in the daily auctions) before, mostly using Centralized Exchanges (linke Binance), who take care of the on-ramping and off-ramping and any KYC processes. The usage of the REX smart contracts does not require an additional KYC process.


In the U.S., the U.S. Department of Treasury’s Financial Crimes Enforcement Network (FinCEN) enforces the Bank Secrecy Act (BSA) - the primary AML law in the U.S. The BSA requires that any money services business (MSB), a person or an entity that provides money transmission services or engages in the transfer of funds (e.g., a “money transmitter”), implement and maintain a modern risk-based AML program. In a 2019 guidance, FinCEN made clear that many cryptocurrency businesses are MSBs. Persons that by any means accept and transmit currency, funds or other “value that substitutes for currency” from one person to another location or person fall within the federal definition of “money transmitter”. According to FinCEN, virtual currency “has an equivalent value as currency, or acts as a substitute for real currency”. Since a money transmitter is a type of MSB, cryptocurrency exchanges, brokers, custodians, ATMs and a myriad of others are required to build AML compliance programs. Registering with FinCEN, maintaining written policies and procedures, filing suspicious activity reports (SARs), utilizing a blockchain intelligence solution to monitor transactions, screening wallets as well as mitigating the risk of fraud and financial crime are some of those requirements.


The "REX" Software is not covered by the Bank Secrecy Act, because

  1. "REX" is not a business, person or entity. No person or group has emitted the tokens. Only users themselves may mint their own tokens at will.
  2. "REX" does not provide money transmission services: It's a cryptocurrency that has a "transfer" function implemented, like any other cryptocurrency - think of it like a Dollar Note providing a transfer function "being handed over". This does not make REX "providing a service".
  3. "REX" does not engage in the transfer of funds.
  4. "REX" is not an exchange, a broker or a custodian.
  5. The "REX" software does nothing itself, so there shall be no expectation of efforts of others, a promoter or other third party.


"REX" is not more than immutable compiled bytecode sitting on the BSC network, that can do nothing on its own but sit there. People can run the code if they want to, or not.

The Howey test

The howey test (https://www.google.com/search?q=Howey+test) defines what U.S. federal securities laws apply to, which the SEC administers.

You must have no expectation of any benefit whatsoever from any BUSD sent to the REX contracts. You must have no expectation of profit from the efforts of others. You must have no reliance on the effort of others. REX is just a piece of inert code at a contract address on the BSC network. It can do absolutely nothing on its own. Every REX that ever exists is caused to exist by a user creating it himself per the rules of the code that he chooses to run that lives at a BSC contract address, and people might refer to as REX, mining his own BSC block or paying a BSC miner to do it for him. Only you can mint your own REX when you run the "endStake" function's code, as it requires your private key. Only you can run the "createStake" function's code to stake your REX, as it requires your private key. Staked REX are actually "burnt" or "destroyed". Only you can mint your own REX when you run the "endStake" function's code, as it requires your private key. The users themselves perform all the work. This is the same way that all BTC are caused to exist, people run code and "coins" are created when the network's rules are met. Wherever possible you agree there is no investment of money. Wherever possible you agree there is no common enterprise.

Liquidity Pool

Just like traditional finance, "decentralized finance" requires liquidity. But rather than that liquidity coming from institutions, DeFi users create liquidity pools, which are crowdsourced token pools that are locked in a smart contract that facilitates trades between the assets on a decentralized exchange (DEX). The REX software has automatically created an automated market maker (AMM), which allow the automatic and permissionless trade of digital assets through liquidity pools. The LP tokens received from adding liquidity to the pool are "burnt" - so the REX Smart Contracts do not hold custody of those tokens ever.


Blockchains, smart contracts, and cryptocurrencies are cutting edge technologies and there is a risk of total failure, however small.

Software is hard. Computers are hard. Distributed software on distributed computers is harder. It's a miracle this stuff works at all.

Strong cryptography seems unlikely to be broken, but if it is, everything will probably be broken.


Bitcoin Miners run computations and mint their own BTC reward if their computation matches what the network consensus code requires. REX stakers run computations and mint their own REX reward if their computation matches what the network consensus code requires. In either network you can run your own code on your own machine, or pay someone else to run the code your choose for you to mint your reward. In Bitcoin the code lives in the node, in REX the code lives in the node at a contract address. Paying a fee is paying someone to run your code.


REX is not an airdrop or a fork.

An airdrop requires someone else control the coins and give them to you.

A fork requires that some code exist and be forked.

If you've read down this far, congratulations. You will notice the theme of all of the above text is that you should have absolutely no expectations of any sort regarding anything, and if anything goes wrong, you shouldn't look for redress anywhere, and you should receive none. When you send BUSD to the contract, you don't get the BUSD back. The only way to possibly get BUSD back via "BigPayDays" is precisely explained in the whitepaper and in the published code itself, but there is no guarantee at all. Software is hard. Blockchain software is harder. We're lucky any of this stuff works at all.
