About RMTX
Listings
Website
RMTX is the Crosschain Token (ETH, POLY, BSC) that provided 10% holder reflections with an additional 1% automated buy back and burn. RMTX is the inaugural token of Rematic Tokens and rewards investors in three ways. First, 10% of all buys, sells, and transfers (not across chains, that free) are distributed to holders. Second, the automated buyback and burn makes RMTX a deflationary token, thus raising the value to all holders over time. Third, and most importantly, as the premier token of Rematic Tokens, a portion of all profits obtained from business generated revenue will be distributed in the form of dividend payments and/or additional RMTX token burns.
The vision of Rematic Tokens LLC (RTL) is to bring a trusted, professional, and business level execution of product development and services to the cryptocurrency, commercial, and public/federal space for its clients and communities. RTL is a legal entity established in the state of Virginia, operating globally. In addition to providing services to other tokens and their communities, it acts on behalf of $RMTX investor interests and serves as the operational arm for the $RMTX community. $RMTX token serves as a funding mechanism and is the inaugural token of Rematic Tokens LLC.
Rematic Tokens LLC product development will be funded by $RMTX, built and managed by RTL, and owned by $RMTX holders. 100% fair, 100% transparent. For more details on utilities, visit the website.

Rematic.buyTokens(uint256) (#1778-1792) sends eth to arbitrary user
Dangerous calls:

Rematic.addLiquidity(uint256,uint256) (#1814-1828) sends eth to arbitrary user
Dangerous calls:

Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.
Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.
