# Engain Features

**Engain Boost**

With Engain Boost, users can receive a higher APR on their liquidity pools or farms. The APR ranges from an additional 25% up to an extra 200%, depending on the user's premium tier. All users must do is hold $ENGI tokens in their wallets or have them in a liquidity pool to earn additional interest with Engain Boost. The boost can be applied once a week to one liquidity pool. It lasts for 24 hours. Suppose the user only has one liquidity pool or the value of the boosted liquidity pool exceeds 10% of the portfolio's worth. In that case, the booster is limited to 10% of the user's portfolio worth.

Engain Boost can be applied to any single token farm or liquidity pool. This will include stablecoins, which usually have a lower APR and can still be boosted by an additional 200% APR (for the Titan premium tier only). The increased interest rate will be paid out in $ENGI tokens from the Liquidity Mining reserves.

**Protocol-owned liquidity**

Engain supports the protocol-owned liquidity approach to provide liquidity to tokens on decentralized exchanges.

Protocol-owned liquidity refers to a liquidity pool that is owned and controlled by a decentralized protocol, such as a blockchain-based platform or a decentralized finance (DeFi) application. Here are some of the benefits of protocol-owned liquidity:

1. Greater liquidity: By owning and managing the liquidity pool themselves, protocols can ensure that there is always sufficient liquidity available for users to trade, borrow or lend assets. This can help to reduce slippage and ensure that transactions can be executed quickly and efficiently.
2. Lower costs: Protocol-owned liquidity can be more cost-effective than relying on third-party liquidity providers. This is because the protocol can avoid paying fees and commissions to external market makers or liquidity providers.
3. More control: By owning and managing the liquidity pool, protocols have greater control over how the liquidity is allocated and distributed. This can help to ensure that the pool is being used most efficiently and effectively as possible, and can help to minimize risks associated with external parties.
4. Increased security: Protocol-owned liquidity can also provide greater security and protection against various risks such as hacks, exit scams, or other types of fraud. This is because the protocol can implement robust security measures and protocols to ensure that the liquidity pool is secure and protected at all times.
5. Improved decentralization: Protocol-owned liquidity can also help to improve the overall decentralization of the DeFi ecosystem.

**Engain ID - SSI (Self-Sovereign Identity)**

With Engain ID, users will connect all the DeFi services with a button, bringing more trust and simplicity to the entire blockchain ecosystem.

Bridges allow the transfer of data and liquidity across blockchains and provide a single, decentralized standard for bridging assets. With Bridges, users can maximize their overall crypto experience without limiting themselves to a single chain or protocol.

Self-Sovereign Identity (SSI) technology allows users to control who has access to their identifying information. Each entry point must request permission to access a user's information, and users can revoke or grant permissions with a swipe of their finger. SSI works across all sources.

Everyone has a unique set of identifying characteristics. This information could include birth dates, citizenship, email addresses, or wallets they use. In the physical world, these are represented as cards and certificates held by the identity holder in a secure place and presented when the person needs to prove their identity.

The Engain identity system allows you to use your digital wallet and authenticate your identity using the credentials you have been issued. You no longer have to hand over control of your personal information to dozens of databases every time you want to gain access to new goods and services, risking having your identity stolen by hackers.
