0x, a leading decentralized exchange (DEX) infrastructure provider, announced the general availability of its Cross-Chain API, a new developer solution that lets any application move value across 25+ blockchains in one single integration. Over $230M was bridged during a private beta that launched in late February, and now the Cross-Chain API is open to all developer teams, aggregating bridging and swap liquidity behind one API that 0x owns and maintains end to end.

Many teams hit the same wall with cross-chain. Multi-chain swaps are seen as a must-have feature but resourcing prevents build and maintaining the infrastructure, so they end up stitching together several providers or using patchwork third-party vendors and absorb every outage, edge case, and breaking change those vendors pass downstream. 0x Cross-Chain API replaces the sprawl with one provider responsible for routing, bridging, tracking, and execution.

"Cross-chain has been the hardest part of onchain to get right, and most teams are either rebuilding it from scratch or duct-taping vendors together and hoping nothing breaks," said Amir Bandeali, CEO at 0x. "We built and operate the entire stack ourselves, so a single integration gives you reliable multi-chain swaps that match the same-chain experience your users already trust. Whether you're settling a payment, moving a tokenized asset, or executing a trade, value can flow freely wherever it needs to go, and your engineers can focus on your core product."

One integration you don't have to maintain

Cross-Chain API is a unified product that handles routing, bridging, tracking, and execution. Because 0x owns and maintains the underlying technology, integrators get fewer dependencies, fewer edge cases, and fewer breaking changes, along with the ability to launch new routes without taking on additional maintenance. Purpose-built for the reliability and compliance requirements of institutional integrators.

This reliability shows up in the numbers. The Cross-Chain API runs at 99.97% uptime, with a median bridge time of 10s and median quote responses under 750ms. It aggregates 12+ bridges while continuously evaluating routes and selecting the best-performing options as network conditions change, with fallback paths built in to reduce reverts and user drop-off.

Built for how value actually moves today

Cross-chain execution is no longer a niche trading feature. It is becoming a default requirement across the most important narratives onchain:

• Payments: settle stablecoin and other token payments across chains in a single action, abstracting bridging away from the end user.
• Tokenization: move tokenized assets and real-world assets (RWAs) to wherever liquidity and demand live, without locking users into one network.
• Trading and treasury: route capital to the best opportunity across EVM networks and Solana, and rebalance treasuries across chains programmatically.
