0x Opens Cross-Chain API to All Developers with 12 Bridge Partners on Day One
0x Protocol (a DEX aggregator API that has routed $180 billion in swap quantity since 2017) opened its Cross-Chain API to normal availability Wednesday. Twelve bridge suppliers are stay from day one, accessible by a single API name.
The associate record consists of Circle, Chainlink, USDT0, Relay Protocol, LayerZero, Optimism, Throughout Protocol, Mayan, Stargate Finance, NEAR Protocol, Fuel.zip and Squid Router. The API delivers routes with a median bridge time of 10 seconds and a quote response beneath 750 milliseconds, per 0x’s product web page. The corporate stories 99.97% uptime on the underlying infrastructure.
For builders, the pitch is consolidation. A pockets or app already on 0x’s Swap API can activate cross-chain routing with out including distributors or writing bridge-specific error dealing with. 0x displays routes in actual time and switches suppliers when one degrades.
The Aggressive Framing
Cross-chain swaps are a contested market. 1inch launched its Fusion+ cross-chain order-flow product in 2024. LayerZero, Wormhole and Throughout every run native bridging stacks with direct developer APIs. These protocols typically require the developer to decide on and keep a particular bridge. 0x is positioning its API because the layer that removes that call.
Throughout Protocol, which makes use of an optimistic oracle to underwrite quick bridge fills, processed greater than $15 billion in bridge quantity in 2025. LayerZero powers OFT-standard token transfers; Stargate is its major consumer-facing software. Each protocols at the moment are listed as companions within the 0x Cross-Chain API — that means 0x is aggregating opponents reasonably than changing them outright.
From Non-public Beta to GA
The Cross-Chain API entered non-public beta on February 25, 2026, with a subset of bridge companions. Wednesday’s announcement removes the invite gate and expands the associate set to 12. 0x has powered swap infrastructure for Coinbase Developer Platform, MetaMask, Phantom, Robinhood Pockets and Belief Pockets, in line with the corporate’s weblog. Cumulative swap quantity has crossed $180 billion throughout 211 million transactions since 2017.
The corporate has not disclosed what number of non-public beta prospects went stay with cross-chain routing, or what mixture quantity the beta produced. That information could be the clearest measure of whether or not the 12-partner launch converts into actual transaction circulation.
Token Disconnect
$ZRX, the governance and charge token for 0x Protocol, trades at $0.0934, a market cap of roughly $79 million at rank #322, per CoinGecko. The token is down about 5% on the day and 96% from its January 2018 all-time excessive of $2.50.
The Cross-Chain API doesn’t route charges on-chain by $ZRX beneath 0x’s present mannequin; the corporate prices integrators on the API degree. That construction means the GA launch doesn’t immediately have an effect on $ZRX tokenomics, even because it expands 0x’s addressable developer market.
