What is 1inch Business Portal
1inch Business Portal is a SaaS Web3 infrastructure platform offering subscription-based access to the broader 1inch ecosystem, built on top of 1inch’s battle-tested and widely adopted swap and execution technology, and designed for developers and businesses building and scaling on-chain applications.
From early-stage startups to enterprises and institutions, 1inch Business Portal provides subscription-based access to the broader 1inch ecosystem, offering a scalable Web3 infrastructure platform built for high-throughput usage, production reliability, and long-term integrations. It supports mission-critical use cases across wallets, fintechs, trading platforms, and infrastructure providers operating under real-world load.
Product Areas
The 1inch Business Portal provides access to a set of core product areas across the broader 1inch ecosystem, enabling developers and businesses to build, operate, and scale on-chain applications using a unified Web3 infrastructure platform.
Swap Execution, DEX Liquidity Aggregation & Orderbook
Includes classic (pro-mode) swaps, intent-based swaps (Fusion), cross-chain swaps (Fusion+), orderbook functionality, and support for real-world assets (RWAs). This product area is designed for aggregating liquidity across decentralized exchanges (DEXs) and executing on-chain trades through both direct, transaction-based swaps and orderbook-driven trading workflows, alongside intent-driven execution models.
Market & Trading Data
Includes spot pricing, orderbook data, token metadata, token details, and market charts. These capabilities support pricing, discovery, analytics, and user-facing trading interfaces.
Portfolio & Account Data
Includes balance information and portfolio composition across supported networks. This product area enables portfolio tracking, asset monitoring, and account-level insights.
Transactions & On-Chain Activity
Includes transaction execution via a gateway, historical transaction data, and execution traces. These capabilities support monitoring, analytics, auditing, and operational workflows.
Network & Infrastructure Data
Includes gas price estimation, Web3 RPC access, and domain resolution. This product area provides production-ready blockchain connectivity for scalable and reliable on-chain interactions.
