# Beamswap v2

## AMM protocol

Similarly to v3, Beamswap v2 featured a decentralized exchange (DEX) and allowed users to supply liquidity and earn passive income from staking and yield farming. However, the transactions were powered by the [automated market maker (AMM) protocol](https://docs.beamswap.io/beamswap-v2/standard-and-stable-amm), both standard and stable.

In its current version, Beamswap v3 is primarily powered by the [concentrated liquidity market maker (CLMM) protocol](https://docs.beamswap.io/products-and-features/decentralized-exchange/beamswap-v3-clmm).

## SHARE token

The v2 version also featured the Beamswap-native [SHARE](https://docs.beamswap.io/beamswap-v2/beamshare-retired) token that complemented the primary platform asset, GLINT, in delivering staking and earning opportunities for users.

In Beamswap v3, SHARE is replaced by the [stGLINT](https://docs.beamswap.io/products-and-features/stglint) token.
