# Introduction

MAYAChain is a decentralised cross-chain liquidity protocol that allows users to add liquidity or swap over that liquidity. It does not peg or wrap assets. Swaps are processed as easily as making a single on-chain transaction.

MAYAChain works by observing transactions to its vaults across all the chains it supports. When the majority of nodes observe funds flowing into the system, they agree on the user's intent (usually expressed through a [memo](https://gitlab.com/mayachain/docs/one-stop-shop/-/blob/main/.gitbook/assets/memos/README.md) within a transaction) and take the appropriate action.

For wallets/interfaces to interact with MAYAChain, they need to:

1. Connect to MAYAChain to obtain information from one or more endpoints.
2. Construct transactions with the correct memos.
3. Send the transactions to MAYAChain Inbound Vaults.

[Front-end](#front-end-development-guides) guides have been developed for fast and simple implementation.

## Front-end Development Guides <a href="#front-end-development-guides" id="front-end-development-guides"></a>

### Native Swaps Guide

Frontend developers can use MAYAChain to access decentralised layer1 swaps between BTC, ETH, DASH, KUJI and more.

### Native Savings Guide

MAYAChain offers a Savings product, which earns yield from Swap fees. Deposit Layer1 Assets to earn in-kind yield. No lockups, penalties, impermanent loss, minimums, maximums or KYC.

{% endcontent-ref %}

### Aggregators

Aggregators can deploy contracts that use custom `swapIn` and `swapOut` cross-chain aggregation to perform swaps before and after MAYAChain.

Eg, swap from an asset on Sushiswap, then MAYAChain, to an asset on Fin in one transaction.

### Libraries

Several libraries exist to allow for rapid integration. xchainjs has seen the most development is recommended.

Eg, swap from layer 1 ETH to BTC and back.

### Analytics

Analysts can build on Midgard or Flipside to access cross-chain metrics and analytics.

Eg, gather information on cross-chain liquidity
