white paper

SafeBank is the initial cryptocurrency banking feature that we’re implementing for investors who want powerful tools that give them more finite control over their investment. It’s a new Dapp from SafeBitcoin. Our long term goal is to bring greater fundamental value to the SafeBTC token and ultimately shift the global mindset of potential investors in a direction that is centered on expansive passive income potential while giving them more control over their investment.
While we continue to push for the goal of making SafeBitcoin one of the top cryptocurrencies in the world, we strive for introducing even more value through fundamentals. This is why the SafeBank branch of our ecosystem combines the immediate passive income of yield reflection from standard tokenomics with the long term high yield passive income of farming a new token with its own DeFi rewards.
SafeBank is just the beginning of a larger roadmap. Future development will include SafeBank Lending, a SafeBitcoin mobile wallet, a specialized SafeBitcoin exchange app, and a SafeBitcoin Visa Card. All of these pieces encapsulate the essence of our vision to build a powerful ecosystem where investors safely and productively control their own passive income.
We want SafeBank to be like a bank but with greater benefits that can only be possible with cryptocurrency for investors but more importantly, we want it to be a better “bank” than run-of-the-mill fiat banks. Fiat based banks around the world enforce long lock periods for money that is put into their savings accounts or CDs. While these do yield some interest, their annual percentage yield is often negligible.
Comparatively, SafeBank brings similar yielded interest in the form of “farming” by staking SafeBTC LP but with exponentially higher APY. When any amount of SafeBTC LP is staked for the farming of SafeBank tokens, a significantly higher and stable APY is applied but without enforcing unnecessarily long locked durations. This means that investors can choose their own staking period and ultimately keep full control of their passive income.
In addition to receiving SafeBank tokens as the SafeBTC LP farming rewards, each transaction of the SafeBank token on BEP-20 or ERC-20 will reward holders with a percentage of a stable USD coin as part of its own tokenomics model.
The passive income potential of the SafeBitcoin ecosystem comes from three main sources: SafeBTC tokenomics, SafeBTC LP (farming SafeBank tokens), and SafeBank tokenomics. We’re serious about building a powerful ecosystem where investors think “passive earning”, “cryptocurrency banking”, and “high yield farming” when they hear or see the SafeBTC, SafeBitcoin, or SafeBank brand names.

Token is either risky or in presale. For presale 30+ is a fine score.

SafeBank.swapAndSendDividends(uint256) (#1981-2001) sends eth to arbitrary user
Dangerous calls:
- (sent,data) = diviTracker.call{value: newBalance}() (#1994)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (#1225-1249):
External calls:
- (sent,data) = user.call{value: _withdrawableDividend}() (#1232)
- success = IERC20(DividendToken).transfer(user,_withdrawableDividend) (#1236)
External calls sending eth:
- (sent,data) = user.call{value: _withdrawableDividend}() (#1232)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (#1241)
Apply the check-effects-interactions pattern.

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.

SafeBank.swapAndLiquify(uint256) (#1821-1902) performs a multiplication on the result of a division:
-wallet3feePortion = otherHalf.div(totalFees).mul(wallet3Fee) (#1846)
Consider ordering multiplication before division.

Reentrancy in SafeBank.updateDividendTracker(address) (#1575-1589):
External calls:
- newDividendTracker.excludeFromDividends(address(newDividendTracker)) (#1582)
- newDividendTracker.excludeFromDividends(address(this)) (#1583)
- newDividendTracker.excludeFromDividends(address(uniswapV2Router)) (#1584)
State variables written after the call(s):
- dividendTracker = newDividendTracker (#1588)
Apply the check-effects-interactions pattern.

SafeBank._transfer(address,address,uint256).lastProcessedIndex (#1811) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

SafeBank.addLiquidity(uint256,uint256) (#1963-1978) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAddress,block.timestamp) (#1969-1976)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#1168) shadows:
- ERC20._symbol (#637) (state variable)
Rename the local variables that shadow another component.

SafeBank.updateFees(uint256,uint256,uint256,uint256,uint256) (#1555-1562) should emit an event for:
- liquidityFee = _liquidityFee (#1557)
- wallet1Fee = _wallet1Fee (#1558)
- wallet2Fee = _wallet2Fee (#1559)
- wallet3Fee = _wallet3Fee (#1560)
- totalFees = tokenRewardsFee.add(liquidityFee).add(wallet1Fee).add(wallet2Fee).add(wallet3Fee) (#1561)
Emit an event for critical parameter changes.

SafeBankDividendTracker.updateTokenForDividend(address).newAddress (#2035) lacks a zero-check on :
- DividendToken = newAddress (#2036)
Check that the address is not zero.

Variable 'SafeBank.swapAndLiquify(uint256).sent (#1859)' in SafeBank.swapAndLiquify(uint256) (#1821-1902) potentially used before declaration: (sent,data) = wallet2Address.call{value: wallet2feeBalance}() (#1874)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

Avoid relying on block.timestamp.
