[1IP-79] Trading Terminal, Limit Orders, and Solana Integration for the Alternative Modular Interface of 1inch

Author: Denis

Simple Summary:

Hello everyone! This is the team behind the alternative 1inch interface. We’re back with a new initiative: building on top of the existing interface, we aim to develop a full-featured trading terminal with limit order support, enhanced swap flow UX, and Solana integration.

We are requesting 12 months and $288,000 in funding to complete this work.

Abstract:

Our goal is not just to add new features, but to take a major step forward in the development of the alternative 1inch interface. We plan to implement:

• support for limit orders,

• a user-friendly trading terminal with charts, order books, and trade history,

• an improved swap flow where all actions (approve, permit, wrap) are unified into a single clear sequence,

• Solana integration,

• interface deployment on IPFS with ENS access,

• phishing protection and technical documentation.

We believe these improvements will make the interface even more user-friendly, secure, and in demand — both for users and developers.

Motivation:

From the beginning, our goal has been to build the best Web3 interface — focusing on simplicity, openness, speed, and independence. Currently, the interface supports Fusion and Fusion+ swaps, and this alone has made us competitive. But traders need more than just fast swaps — they need tools: orders, charts, history, control. And we want to give them that.

We also want to highlight an issue we’ve encountered: in the past six months, we’ve discovered over five phishing sites using our code. This is alarming. We've already taken a major step by implementing the DevPortal Proxy, which not only optimizes requests but also helps detect unauthorized copies of the interface and analyze suspicious activity. It's not just a proxy server — it's a full-fledged monitoring and anti-phishing system.

To improve stability and manageability, the proxy infrastructure was migrated to Kubernetes. This gives us flexibility in deployment and scaling, and allows us to relocate proxy services to any region quickly. This approach significantly increases the system’s reliability and resilience against external threats.

Additionally, as our team grew, we realized the importance of comprehensive documentation — not only for ourselves, but also for future auditors who need to understand the project architecture. As part of this grant, we aim to document key parts of the codebase.

Specification:

We currently have over 50 tasks queued for improving code, architecture, and security. For this proposal, we will focus on the following areas:

• Implementing a limit order module based on 1inch DevPortal and onchain sources.

• Developing a trading terminal:

  • integrating price charts (currently researching the optimal solution),

  • displaying order books,

  • trade history and user order history.

• Building a complete activity history in the Account View section.

• Sending and receiving funds directly in the interface.

• Updating the swap UX — combining all steps into a clear, visual flow.

• Extending the embeddable widget system (currently a basic swap widget is implemented; we want to expand this and deliver the full trading terminal as a widget).

• Adding support for the Solana network — tokens, routing, compatibility.

• Deploying the interface on IPFS with ENS (we’ve already secured the 1inch-community.eth name, test version available at https://1inch-community.eth.limo).

• Automating publishing and updates via CI/CD to IPFS.

• Further improving the phishing protection system.

• Preparing architectural and technical documentation.

• Direct integration of hardware wallets (Ledger and Trezor — technical research is underway).

Below I would like to demonstrate an early draft of the trading terminal:

Rationale:

We’ve come a long way — from a basic swap interface (1IP-50) to a modular solution with Fusion+ support and phishing protection (1IP-66). Everything we do is open, transparent, and flexible. Now it’s time to expand the functionality and provide traders with advanced tools. This will enable integration into DApps, wallets, and trading platforms. We aim not just to catch up — but to lead.

We also highly value community input in this project’s development. If you have suggestions, ideas, or comments — we would love to hear them in the forum thread. Your feedback helps guide us in the right direction and make the interface better for everyone.

Considerations:

Security:

• All interaction with 1inch Dev Portal occurs only through https and an authorized proxy, which ensures a secure channel.

• The proxy infrastructure is protected using WAF, CORS, and a monitoring system.

• The architecture is built on Kubernetes, ensuring rapid response to threats and scalability.

Infrastructure and Distribution:

• Production deployment on IPFS with ENS.

• Automatic CI/CD publishing for new builds.

• Phishing monitoring system.

Documentation and Support:

• Code documentation for better internal understanding and external auditing.

• Continued modularization and embeddability improvements.

Budget and Team:

• Total budget: $288,000 for 12 months.

• If approved, 288,000 USDC will be transferred to the Operations Multi-Sig (0x45e84e10e8E85c583C002A40007D10629EF80fAF) and then paid out to 0x568D3086f5377e59BF2Ef77bd1051486b581b214 as follows:

  • An initial payment of 24,000 USDC as an advance.

  • The remaining 264,000 USDC to be streamed over the next 11 months.

Team:

• Lead developer — author of 1IP-50 and 1IP-66,

• Frontend developer with 10+ years of experience,

• UI/UX designer who has been helping us deliver the best user experience,

• QA engineer and former QA core team member at 1inch with deep DeFi testing experience.

Funding will cover:

• Developer services, including:

  • Solana integration and system modernization,

  • Infrastructure maintenance and extension (CI/CD, proxy, servers),

  • Documentation preparation, publication, and maintenance.

• QA services:

  • Swap and limit order flow testing,

  • Widget system testing,

  • Desktop app testing.

• Design services:

  • UI/UX improvements and architecture updates,

  • Design for the limit order interface,

  • UI/UX enhancements for Solana support.

• Security, testing, and update releases.

• Domain costs.

• Other services required for monitoring and security.

• A small reserve for future team expansion.

1IP-66 Work Report:

Here we would like to share the results of the work completed under 1IP-66.

Fully Completed:

• Fusion+ functionality implemented, including related refactoring for cross-chain flow.

• Private proxy server-based phishing protection system deployed.

• Account View implemented.

• CI/CD modernization completed — automatic publishing of all project libraries to GitHub Packages.

• Major infrastructure upgrade: proxy wrapped in Kubernetes for flexibility and scalability, with global load balancing for improved performance.

Not Fully Completed:

• Permit2: the frontend implementation is done, but due to issues on the 1inch DevPortal side, it’s temporarily disabled. We’ve reported the issue to the 1inch team and are waiting for a fix. As soon as it’s resolved, we’ll re-enable, test, and release Permit2 functionality.

• We weren’t able to fully implement automatic code signing for the macOS desktop app, due to communication issues with Apple support. We’re currently resolving this, and will resume once we gain the necessary developer rights.

• Initial load performance: to protect users from phishing, we implemented an interface verification system, which increased initial load time. This is a temporary issue — we plan to fix it soon by introducing bypass mechanisms without compromising user safety.
