Since 2017, 0x has built technology that enables on-chain value flow in an increasingly fragmented ecosystem, from the first onchain orderbook to today’s leading trading APIs. Established in San Francisco, we power 500+ companies including fintechs, institutions, exchanges, and wallets, and give you control over tech and compliance, unlike API wrappers that explicitly waive responsibility for the underlying technology.



One integration with 0x lets your business settle value on and across blockchain networks, wired directly into the infrastructure layer that routes payments, tokenized stocks, cryptocurrencies, subscriptions, and more. While other providers wrap and repackage APIs from multiple vendors, causing worse execution, less revenue, and limited support, 0x connects you directly with the value flow, giving you maximum control over routing, compliance, monetization, and support.
Proudly headquartered in the United States, 0x lets you ship onchain products and services within a regulatory posture required for global business. We keep you at the frontier of onchain settlement, with a holistic service that covers more than just the APIs and routing logic.
Integrate 0x on your terms for direct control over every aspect of the implementation from asset support to commercials, with the full digital asset ecosystem under one provider for same-chain and cross-chain transactions. Going direct instead of through a third-party API wrapper ensures better execution, greater transparency, more revenue levers, and a single point of contact if anything breaks.
There are many benefits to a direct integration of 0x. As your technology provider, we work closely with your team to understand your specific priorities and pain points, so we can exceed expectations across the board.
Immutable Settler contracts, not upgradeable facet-based proxies. Nothing can change the code your users approve.
Standing approvals go only to Permit2, and every order is a fresh EIP-712 signature. Unlike other providers, we moved away from upgradeable contracts in 2023 due to security concerns around token allowances.
~72% best adjusted price with low reverts, and better performance than any third-party API wrapper, ranked #1 on third-party benchmarks.
NBBO-style routing aggregates 373+ venues, plus no-slippage RFQ and proprietary AMMs. The price that's quoted is the price that executes.
99.92% uptime, 4.4% revert rate, <150ms median quote latency, and a holistic approach that accounts for downtime outside the 0x stack.
Performance is measured continuously and shared openly, so your team can hold the service to numbers instead of marketing claims.
US compliance posture, non-custodial, with CipherOwl screening, emergency suspensions, and implementation-specific controls.
A clean regulatory perimeter with wallet screening at quote time and controls your compliance team can audit, customize, and pause.
Fee economics you can customize and control.
Set your own fee model and capture revenue directly instead of leaving it for your current provider. The economics are yours to configure, based on your compliance needs and service offerings.
