1inch Developer Portals Introduces Orderbook API for Efficient Limit Orders

**1inch Aqua is preparing to launch its first implementation on Ethereum mainnet within two weeks.** The project, called AquaZero, was built on the 1inch Aqua protocol and won a main prize at ETHGlobal. It's being incubated by 1inch. **Key features:** - Shared liquidity model - Live deployment scheduled for mainnet in 2 weeks - First proof-of-concept for Aqua protocol Aqua is a liquidity protocol designed to improve capital efficiency by allowing liquidity providers to keep funds in their accounts while sharing them across multiple strategies simultaneously. The mainnet launch represents a significant milestone for the protocol, moving from concept to live implementation.

**Tokenized SpaceX equity** saw $3.86B in trading volume during June 2026, with the majority of activity concentrated on decentralized platforms. **Key metrics:** - 78.5% of June's EVM trading volume processed through 1inch - SPCXon and SPCXx tokens available for trading - Gasless swaps with MEV protection via intent-based architecture **Market context:** Binance holds over 60% market share for SpaceX perpetual futures ($SPCXUSDT), making it their second-largest traded product after Bitcoin. The platform recorded $5.6B in 24-hour volume as of June 13, with cumulative volume exceeding $9.0B across pre-IPO and post-listing phases. The tokenized equity market continues to gain traction as traditional financial instruments migrate to blockchain infrastructure.

**The Problem:** Large tokenized real-world asset (RWA) and stock trades remain visible in public mempools, making them vulnerable to front-running and sandwich attacks that extract value from traders. **1inch's Solution:** - Routes RWA swaps through **intent-based execution** - Orders filled by resolvers **off the public mempool** - No exposed orders means **no MEV extraction** **Infrastructure Advantage:** 1inch operates non-custodial routing for **27M+ connected wallets**, handling regulated assets without custodial requirements—infrastructure tested at scale before tokenized RWAs needed it.

**1inch has appointed Holly Atkinson as Chief Product and Technology Officer.** Atkinson will lead product strategy for the protocol's core routing infrastructure and oversee the launch of Aqua, a shared liquidity product. **Key responsibilities:** - Managing product strategy across 1inch's routing infrastructure - Leading the development and launch of Aqua - Leveraging her experience in full-stack engineering and blockchain architecture Atkinson brings expertise spanning full-stack engineering, blockchain architecture, and executive leadership to the role. The protocol maintains its focus on delivering optimal rates, deep liquidity, and robust DeFi infrastructure.

**1inch Business has launched a unified API** that packages tokenized real-world assets (RWAs) and tokenized stock routing into a single integration point for wallets, fintechs, and protocols. **The problem it solves:** - Building RWA infrastructure from scratch typically requires months of development - Teams must handle compliance filters, pricing feeds, and liquidity access separately - RWA liquidity remains fragmented across multiple platforms **What's included:** - Pre-built compliance and routing infrastructure - Aggregated execution across fragmented RWA liquidity sources - Integration with existing RWA providers like [Ondo Finance](https://ondofinance.com) and xStocks **Why it matters:** The API removes technical barriers that have prevented RWAs from becoming widely usable in DeFi. Instead of building complex infrastructure, projects can now integrate tokenized assets through a single endpoint. For teams looking to add RWA trading capabilities, this reduces implementation time from months to a single API integration.
