# Technological Basis of Engain

### What options are available on the Engain platform?

* It is possible to hold funds in non-custodial wallets and smart contracts. This will work like Metamask and Trust Wallet but be more convenient, prettier, and safer. Engain must simplify the approach of multiple seemingly identical assets (wrapped coins, forks, and other things) so it will be easier to work with casual users without deep knowledge.
* With the integrated swap functionality, users can be confident in receiving the best exchange rates. This is particularly beneficial for users who are new to the DeFi space, enabling them to purchase tokens not yet available on larger exchanges (Binance, KuCoin, etc.) through the user-friendly Engain interface.

Engain will offer an integrated **cross-chain bridge** that will allow users to input tokens on one chain and receive the output in tokens from another chain.&#x20;

During the early stages of Engain's development, third-party bridges will be formed and used to automate the types of transactions mentioned above. We intend to launch our MVP within the Arbitrum layer for smooth integration into Ethereum so we can harness the power of the community right away. However, as the Engain platform grows, custom bridges and coin reserves will be built that will be owned by Engain, allowing users to make cross-chain trades instantly.

For such a task, we will use the possibilities of the Cosmos SDK. We want to build the infrastructure on our own to have an efficient basis after the MVP for a true multi-chain project. Tokens are to be swapped between the chains via the Cosmos SDK, which can exchange tokens using a third-party token to pay lower transaction fees. [Cosmos IBC](https://docs.cosmos.network/v0.45/ibc/overview.html). This technology enables you to interact with other projects for more than just swaps.

Following the example used, the inserted coins will be sent to the Engain reserve wallet on Ethereum. To swap them into CAKE instantly and credit the user, USDT from the coin reserve on BSC will be used. Depending on the past trading behaviors of the entire Engain community, the coin reserves on each blockchain have the flexibility to increase or decrease in size for maximum efficiency.

Coins will be sent in batches using the official bridges in the background to save gas and transaction fees for users. For automatic cross-chain trades, the standard 0.1% fee (or reduced fee for Engain premium tiers) will be applied. On-chain trades can be free of charge.

An endless source of liquidity on the platform is provided by the Automated Market Maker (AMM) matching machine. Put down the amount of money you want to invest, and Engain will give you the best offer bundles so you can go ahead with it.

The map itself conveys the idea that it is possible to connect to dozens of liquidity providers and search for the best exchange rate at the time, resulting in the best solution and proposal for each user at all times.

* Dashboard / monthly P\&L. Every user on the platform will have the daily/monthly/by deal P\&L, where all the numbers and metrics are shown. So, it’s a modernized version of the personal accountant. Also, the general dashboard is powered by Engain’s AMM and shows the personal funds analytics within one platform, so you can forget about Excel.
* Flash loans to operate with high-APY deals even without any budget. Show the performance with an interest fee within 1 transaction and go through it if you have more than enough assets to cover the deal.
* Borrow/lend/liquidity pools/staking and more **profitable deals**, where you can easily make the money. As it is supposed to propose aggregation and connection to multiple pools with assets Engain can provide a lot of great options for users with arrangements according to the risk and the time of using the desired tool. Thus users can operate with borrowing and lending of assets, various liquidity pools with staking and Insurance option for safety in one case and additional profit in another case.
* Insurance protection is a way of unique approach for users that can provide an income and a way of covering the potential dangers that seem to be dangerous for them without interaction and decision of any other party around.
* Unique options: NFT boost pools, group token pools, etc. It is obvious, how cool it is to be the first who will have benefits by testing things, that are pretty new on the market, so there is a created Engain’s UOP (unique option pools) making this possible.
