# AMM: Automated Market Maker

Bancor is recognized for its foundational role in the DeFi space, having developed the first fully [decentralized AMM powered exchange](https://blog.bancor.network/rethinking-the-order-book-the-march-towards-automated-markets-150f1325fb8c). Bancor's debut [introduced](https://patents.google.com/patent/US11107049B2/en?q=\(Methods+for+Exchanging+and+Evaluating+Virtual+Currency\)\&oq=Methods+for+Exchanging+and+Evaluating+Virtual+Currency) the equations, mechanisms, and concepts that continue to serve as the bedrock on which decentralized exchange remains founded a decade later.

Bancor introduced a network of onchain liquidity pools to pair pools of tokens with one another. Users can trade against these pooled token pairs, with prices set algorithmically based on both the size of the user’s trade and the depth of the corresponding token pools.

This novel approach to market making proved to be a paradigm shift within the decentralized exchange (DEX) space. Traders now have guaranteed access to onchain liquidity with transparent, upfront pricing, doing away with the need for a counterparty. Token owners can also turn existing holdings into productive assets through liquidity provision to these DEX pools, earning returns from protocol swap fees imposed on trades that get routed through the platform.

This has turned pooled market-maker liquidity into a new asset class (“liquidity positions”), allowing for broader, more competitive involvement in market making.

Bancor's foundational [whitepaper](https://bancor.network/whitepaper), penned in 2017, lists Eyal Hertzog, Galia Benartzi, and Guy Benartzi as its architects. The name Bancor pays homage to John Maynard Keynes, who, in 1940, introduced the term to conceptualize a supranational currency.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.bancor.network/bancor-amm/amm-automated-market-maker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
