ZeroFi

ZeroFi is a proprietary automated market maker (prop AMM) on Solana, live since December 2024. It has no public frontend and takes almost all of its order flow from DEX aggregators, primarily Jupiter, which route swaps to its pools when its quote is best.

The operator posts its own inventory into on-chain vaults and quotes prices from the ZeroFi program, so every fill is against the operator rather than pooled liquidity-provider capital. It earns the spread embedded in its quotes; the swap instructions carry no separate fee field, and there is no governance token.

ZeroFi is operated by a professional market-making team that has not disclosed its identity and publishes no website, documentation or social accounts.
