Saber
Solana Ecosystem · Deep
The first major stableswap AMM on Solana, using a Curve-style invariant for efficient swaps between same-peg assets such as stablecoins and wrapped token variants. Saber reached peak TVL of over $4B in 2021, becoming the largest protocol on Solana by TVL at that time. The protocol pioneered the stableswap model on Solana but declined significantly by 2023 as liquidity migrated to newer platforms.
