# StableSwap pools: low slippage near balance and risk away from it

StableSwap concentrates exchange liquidity near an intended balance between related assets. Its invariant behaves more like constant sum near balance and moves toward constant-product behavior as inventory becomes uneven. The amplification parameter controls that shape; it cannot make a failing asset worth its intended reference value.

## Key facts

- **Near balance:** The curve is relatively flat near its intended balance. ([StableSwap whitepaper](https://docs.curve.finance/assets/files/whitepaper_stableswap-fc0bb370db9fe3a91afdde8662e78206.pdf))
- **Amplification:** Lower amplification moves the design closer to constant product. ([StableSwap whitepaper](https://docs.curve.finance/assets/files/whitepaper_stableswap-fc0bb370db9fe3a91afdde8662e78206.pdf))
- **Imbalance:** The curve changes behavior as one asset becomes scarce. ([StableSwap whitepaper](https://docs.curve.finance/assets/files/whitepaper_stableswap-fc0bb370db9fe3a91afdde8662e78206.pdf))

## Separate a useful curve from a price guarantee

Imagine a pool designed for two assets normally exchanging near one-to-one. Small trades around balanced inventory can receive rates close to that ratio. If users consistently sell A to receive B, the pool accumulates A and loses B. The next quote reflects that changing inventory.

If A’s external value deteriorates, a mechanically quoted exchange does not repair its backing. LPs can end up holding more of the less desirable asset.

## Amplification is a modeling choice

The original paper’s amplification analogy describes the shape and concentration of liquidity. It is not a statement that the LP personally borrowed a stated multiple of their deposit. Actual implementations also have fees, asset scaling and version-specific controls.

## Use the whitepaper for mechanics

The cited 2019 paper includes historical simulations and return figures. They are not current yields and are not adopted as forecasts here. A practical pool assessment also needs the exact asset contracts, current balances and contract version; the words stable pool do not identify those dependencies.

## Questions

### Does low slippage make a stable pool risk-free?

No. The invariant can improve execution around its intended balance while depositors remain exposed to asset and implementation failures.
