TeddyDoge is a community-driven organization built to solve what might be called the “One-stop full-featured decentralized exchange.” Teddyswap progress is intended to create a broader range of network effects.

Thus far, the core products, which will be described in more detail here, include swap, aggregate transactions,liquidity,Farm,15 mainstream chain transactions, 15 mainstream cross-chain,15 mainstream chain chart system,Token and liquidity multi-scheme locking,TeddyWallet and derivatives.

Teddyswap’s products are configured in a way that allows the entire platform to maintain decentralized governance of TEDDY token holders, while continuing to innovate on the collective foundations by design. Whereas major structural changes are voted on by the community, the day-to-day operations, rebalancing of pools and ratios, business strategy, and overall development is ultimately decided on by our Teddyswap team.

Pragma version^0.8.0 (#2) allows old versions
solc-0.8.10 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.

Low level call in Address.sendValue(address,uint256) (#79-82):
- (success) = to.call{value: amount}() (#80)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#96-110):
- (success,returndata) = target.call{value: weiValue}(data) (#97)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable IPancakeSwapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#172) is too similar to IPancakeSwapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#173)
