What is a DEX aggregator?
A DEX aggregator is a tool that scans multiple decentralized exchanges and liquidity sources, then routes your trade for the best overall price with the least slippage. Instead of checking each DEX manually, you get one optimized quote. Sally aggregates across 12+ DEXes on Base and BNB Smart Chain.
A DEX aggregator is a router that shops every venue at once. Liquidity for a given token is scattered across many decentralized exchanges and pools, each quoting a slightly different price. Rather than make you check them one by one, an aggregator queries them together, compares the results, and may even split a single trade across several pools to squeeze out a better overall rate.
This matters most for larger trades and thinner tokens, where the difference between the best and worst route can be substantial. By finding deeper combined liquidity, an aggregator reduces price impact and slippage, so more of your money ends up as tokens rather than lost to a bad path. It does this while staying non-custodial — the trade still settles directly from your wallet through the underlying DEX contracts.
Sally is a DEX aggregator for Base and BNB Smart Chain, routing across 12+ exchanges including Uniswap V2, V3 and V4, Aerodrome and its Slipstream pools, and PancakeSwap. It surfaces the chosen route and the estimated price impact before you confirm, and because the same engine powers its embeddable widget, sites that integrate Sally pass that best-price routing on to their own users while earning referral fees on the volume.
