Trading volumes on popular decentralized exchange (DEX) aggregators have surged to new highs over the past few weeks.

Decentralized exchange aggregators provide a way for token traders and swappers to scan several DEX platforms to get the best swap rates at the time.

According to Dune analytics, popular DEX aggregators such as 1inch, 0x and ParaSwap have seen their volumes surging over the past month. The combined volume for those three hit a cumulative weekly all-time high of $6 billion last week, increasing by around 50% since the beginning of November.

1inch has the lead in terms of the current market share at 55% according to Dune, but 0x is catching up with 42% recorded for December so far. Last week, 1inch announced a Series B funding round led by Amber Group that raised $175 million.

According to 0xTracker, the DEX aggregator has processed $3 billion in volume over the past seven days.

0x provides an application programming interface that can be used by DeFi developers to integrate token swaps sourced from leading DEXs directly into smart contracts.

The 0x protocol also has a native DEX called Matcha, which has processed $4.7 billion in trade volume over the past 30 days as reported by its dashboard.

Dune’s DEX analytics reports that there has been $4 billion in trading volume on decentralized exchanges over the past 24 hours and $33 billion for the past week. The aggregator share of that volume is currently 20%.

Uniswap is the current DEX market leader by a long way with a 79% share, according to Dune. It has processed $26.2 billion in trading volume over the past week. SushiSwap, which was originally cloned from Uniswap, ranks in second place with a 9.8% share of the DEX market.
