Contrary to other AMM protocols, Bancor uses its protocol token, BNT, as the counterpart asset in every pool. Using an elastic BNT supply, the v2.1 protocol co-invests in pools alongside LPs to support single-sided AMM exposure and to cover the cost of impermanent loss with swap fees earned from its co-investments.
