**Summary:**
> This pool contains a boosted / linear stable pool token bb-am-USD - Balancer’s AAVE boosted stable pool token & the stMATIC-bb-a-WMATIC pool token. These pools leverage the yield bearing versions of stable coins, USDC, USDT, DAI and stMATIC-WMATIC pairing in a 50/50 weighted pool. This will make a highly capital efficient route for LPs to keep exposure to stMATIC and stable coins while earning yield through AAVE. The protocol will be earning yield on the boosted portion of this pool, making the token pairing more efficient for both parties. This gauge would enter as a “core pool” under BIP-19, meaning protocol fees earned by this pool would be used to bribe for votes on it.

**Protocol Description:**
> bb-a-USD is a Balancer’s primary stable coin liquidity on polygon, leveraging AAVE’s boosted strategy. stMATIC-bb-a-WMATIC BPT is the Balancer [pool token](https://forum.balancer.fi/t/bip-234-enable-stmatic-bb-a-wmatic-gauge-polygon/4558) containing the respective tokens governance token.
**Motivation:**
> Balancer has been expanding into yield bearing tokens and with the release of AAVE v3 there is a migratory push to have assets earning passive yield while underlying trades are facilitate and optimized from both the trader and LP perspectives. This pool executes this by nesting various tokens specific to Polygon network.
