The Bancor Vortex, launched early last year, collects a protocol-wide administration fee from liquidity providers. In version 2, the vortex collected fees in various tokens, which were then exchanged for BNT. The BNT was then used to buy and burn vBNT, ultimately reducing the circulating supply of BNT.
