Saber is a decentralized exchange that enables permissionless trading of pegged assets on Solana.
Saber is a decentralized exchange that is an unauthorized fork of Curve on Solana. Saber leverages the stableswap AMM algorithm which is a combination of the constant product (popularized by Uniswap) and constant sum formula. Trading occurs on a constant sum curve when the pool is relatively balanced and switches to a constant product curve when imbalanced. This allows for lower slippage and impermanent loss but is only applicable to similarly priced assets like stablecoins. The protocol charges a fee on every trade within a pool.
Saber makes money through protocol fees that are currently set at less than 1% for swaps.
You earn swap fees for providing liquidity on Saber. Each pool also provides incentives in the form of native protocol tokens and the SBR token, which is used for governance purposes. Currently, there is not mechanism to accrue value back to SBR holders.
