The market for automated market maker exchanges is a huge industry in itself across different crypto networks. Almost all blockchain in some way holds exchanges for facilitating their user base. Like all other major blockchains, Binance smart chain too, has a number of exchanges on the platform certainly due to its higher transaction throughput and speed.

Kikswap's competitors on Binance smart chain includes, pantherswap, pancakeswap panda swap, jetswap and many others. 

Technical specification

A liquidity pool is a smart contract that holds reserves for two or more tokens and allows anyone to deposit or withdraw funds only according to very specific rules. 

One such rule is the constant product expression x * y = k. Where x and y are spares for the two tokens A and B. To withdraw a certain amount from Token A, you need to deposit a proportional amount from Token B to maintain a certain k value before the fee.

Multi-chain staking

Kikswap is the first multi chain staking protocol pegged to meme tokens. With multi chain technology on the network its community members will be able to stake any of meme tokens on kikswap's staking pools. It will be a de facto staking token for all meme currencies using a similar strategy. 

Each meme token will have a different set of validators and delegators on the network. Whilst having their respective staking pools, where users can stake KIK in return for rewards in form of meme currencies. 

• Staking pool 1
  Invest KIK to get reward in Shib
  APR ≈ 107,310%

• Staking pool 2
  Invest KIK o get reward in Doge
  APR ≈ 179,546%

• Staking pool 3
  Invest KIK to get rewards in KIK
  APR ≈ 110,244.30%

MAP Protocol's testnet, Makalu PoC-2 was officially launched on December 10, 2021. Makalu PoC-2 is equivalent to MAP testnet, in the sense that it upgraded the consensus mechanism on the basis of the original PoC-1. Makalu PoC-2 upgrades the consensus mechanism to POS, from the original POW, with high TPS performance standards. This allows it to utilize cross-chain transaction data (assets) and perform “on-chain upgrades” in a flexible manner, while greatly improving transaction processing speed.

Official Launch of MAP Protocol's Makalu Poc-2 Brings Much-Needed Upgrades

Makalu PoC-2 makes use of the IBFT algorithm to achieve message consensus between nodes and implement Validator registration and election functions in the form of on-chain contracts and supports. Makalu PoC-2 will also continue to support light client verification to verify on-chain transactions on the peer chain, while being compatible with and supporting EIP-1559. PoC-2 will continue to update multiple versions in the form of small version iterations.

MAP Protocol is considered the “Blockchain Assets Freeway,” as it is a cross-chain bridging protocol that aims to provide a secure end-to-end solution for any blockchain to move assets freely. To fulfill this role, MAP Protocol is built on three layers simultaneously.

The first layer, MAP Chain, known as the base layer, is a dedicated blockchain serving as the infrastructure freeway connecting all kinds of blockchains to break barriers.

Secondly, the asset layer provides an infrastructure freeway linking other blockchains (cross-chain support), allowing all kinds of assets to be mapped to MAP Chain in a non-custodial style via trustless smart contract. 

This is followed by the DeFi Application layer, allowing all kinds of applications, including but not limited to DEXs, games and NFTs that can be built with the cross-chain capabilities enabled by MAP Chain and MAP Assets. This also allows fast trades of NFT tokens in a cross-chain decentralized manner, while applications can be easily built using the underlying light client and assets vault.

Following the December testnet upgrade, the focus in the next stage will be on MAP's ecological construction, especially the high frequency of NFT and GameFi development that is changing the dynamics of the traditional gaming industry. This market has been always our key focus, and is expected to continue seeing explosive growth in the future. MAP Protocol is a cross-chain and will have its own independent ecology. For the future development of NFT and Gamefi, cross-chain will be an indispensable component that cannot be ignored.

MAP Protocol will deploy its applications on all the major chains, supporting cross-chain swaps. This will allow all the assets on MAP Chain to circulate freely across all chains. MAP Protocol also welcomes additional GameFi, NFT and Metaverse projects to publish assets on the MAP Chain and join the MAP ecosystem.

MAP Protocol is also compatible with EVM. All EVM chain assets and projects such as Ethereum can be issued to MAP, and MAP will be motivated through various means including ecological incentives.

To promote MAP Protocol's cross-chain technology, cooperation and partnerships opportunities with more public chains will be established. For the purpose of accessing more public chains, MAP will optimize protocols and provide support for cross-chain oracles, lending and other DApps.

HBSwap's mission is to empower people around the world with equal access to banking and participation in the global financial markets. We believe people in the under-developed nations should have equal financial market access as people living in the developing and developed nations. 

Today a user can access the HBSwap with a built-in web-browser wallet on a mobile phone or a notebook, without downloading any APP or software. Using one's email to receive an authentication code. Within minutes a user can begin sending, receiving and trading BTC, ETH, BNB and USDT.  Making investments using ETH or BNB in liquidity staking or participating in BTC and ETH collateralized lending, as a lender or a borrower.

HBSwap will enable Social Coin Offering (SCO), where everyone can easily mint, gift, sell and trade their own personal tokens with their family and friends. SCO will be conducted on HBSwap's Launchpad. Currently HBSwap's platform token HBS is available on the Launchpad for fixed price swap at USDT0.018. 

HBS is a multi-chain token, where you can send HBS (Ethereum) tokens to an Ethereum wallet, later deposit HBS (Ethereum) tokens into HBSwap wallet and switch to HBS (BSC) tokens to send to a BSC wallet. The HBS (Ethereum) and HBS (BSC) token switch is automatic simply by selecting the token type to send. HBSwap unlocks multi-chain liquidity between Ethereum and BSC networks. 

As part of the roadmap, HBS tokens can be traded on Uniswap and PancakeSwap, in addition to trading on HBSwap. Unlike MetaMask wallet, which provide users multiple single chain wallets, HBSwap wallet is a multi-chain wallet, were you can store BTC, ETH and BNB in one single wallet, without the need to change the network settings.

Built on the MASFi public chain, HBSwap is the world's fastest cross-chain DeFi platform with a next generation exchange. Users can trade cross-chain pairs, such as BTC/USDT and BNB/USDT, with token pairs generated on different public chains. Trading and transfer of BTC and ETH are completed in 1-3 seconds with gas or transfer fee of US$0.10 per transfer, which is waived during the initial launch period. For payment applications, HBSwap, by solving the slow speed and high gas fees of BTC and ETH, supports these tokens as a means of cross-border transfer and even for micropayment.

DeFi services including OTC or block trading of BTC and managed fund products with a period of 30 days to 6 months will be introduced. Various third party DeFi products and services will also be available on HBSwap connected via API, such as USD or Euro access, credit cards, fund products, financial games, NFTs, etc. HBSwap's smart contract wallet enables automated and transparent fee sharing arrangements with strategic business partners.
