0x Labs, the startup behind the 0x exchange protocol and a provider of decentralized exchange infrastructure, raises $15M Series A led by Pantera Capital

Context & Ripple Effects
0x Labs' path to this round runs through a different funding model entirely: in 2017 the project raised $24M as ZeroEx through an ICO for the 0x protocol, which let traders swap Ethereum ERC-20 tokens without centralized exchanges. This $15M Series A marks the pivot from community token sale to conventional venture equity, with Pantera Capital — an active crypto fund that also backs trading platforms like Figure Markets — leading the check.
The bet pays off on the timeline of the coverage: fourteen months later 0x Labs closes a $70M Series B led by Greylock with OpenSea and Coinbase participating, while rival Uniswap Labs pulls in a far larger $165M Series B — evidence that decentralized exchange infrastructure became one of DeFi's most heavily capitalized categories.
First-order effects
- 0x Labs gains $15M and a tier-one crypto investor to scale its exchange-infrastructure business beyond the protocol's original token-funded budget.
- Pantera Capital adds a foundational DEX layer position to a portfolio already weighted toward crypto trading venues.
Second-order effects
- Competing DEX players are forced into the same institutional fundraising race — Uniswap Labs' subsequent $165M Series B shows how quickly the bar for infrastructure capital rises once VCs validate the category.
- Aggregators and front-ends such as OpenSea and Coinbase gain a better-capitalized liquidity-routing partner, tightening integration relationships between consumer platforms and underlying swap protocols.
Third-order effects
- Protocol projects born as token sales are re-founding themselves as equity-backed startups, splitting governance and economics between token holders and new VC investors — a structural tension every major DEX now carries.
- If the pattern holds, DEX infrastructure consolidates around a handful of deeply funded protocol teams, with later entrants like Ellipsis Labs' Phoenix needing differentiated designs rather than just capital to compete.
The trend: Decentralized exchange infrastructure is graduating from community ICOs to nine-figure institutional venture rounds, with funds like Pantera and Greylock underwriting the swap layer of crypto markets.
