white paper

VaultDeFi is a unique multi-token project with flexible and interchangeable commodities. These assets have been uniquely designed to reward holders with proprietary double compounding interest, highlighted with our innovative “delete bag” function that burns a percentage of the current supply with all transactions creating a direct benefit to the current market supply developing a larger market share for all investors. Having hyper-deflationary rewarding assets are revolutionary in the DeFi space and will be beneficial to all investors, especially the latest Vault token that rewards in an XSurge wrapped central market commodities with variants and intermediary vehicles.

VaultDeFi’s distinctive reflections system allows Digital Asset investors to diversify their portfolios even while only holding a single token. The SafeVault token includes a dividend of BUSD.

SafeVault.buyTokens(uint256,address) (#1152-1166) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,to,block.timestamp.add(30)) (#1157-1162)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.


Combination 2: Unchecked transfer + 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.

solc-0.8.5 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
