Trader Joe (now LFJ) pioneered the Liquidity Book AMM design and remains the leading Avalanche DEX with multi-chain reach (BNB, Arbitrum added). Rebranded to LFJ with expanded product suite.
What LFJ is
Trader Joe rebranded to LFJ in 2024 to reflect its multi-chain focus. Liquidity Book (V2) is a novel take on concentrated liquidity — discrete price bins instead of continuous ranges.
Verdict
LFJ (Trader Joe) remains Avalanche's dominant DEX with growing multi-chain reach. Liquidity Book design is genuinely innovative among AMMs.
