[2601 Grant] SwaptoX Aggregator – Milestone 1

Project Name & Description

Project Name: SwaptoX Aggregator

Description:
SwaptoX is a decentralized swap aggregator designed to provide optimal swap routing across multiple liquidity sources, with strong support for long-tail tokens and precise pricing logic. The project has been live and production-deployed on Base for over four months, supporting 600+ tokens, and has undergone extensive real-world testing.

SwaptoX is built as general-purpose DeFi infrastructure, enabling wallets, DApps, bots, and future BTCFi applications to integrate swap functionality via SDKs and APIs, rather than relying on heavy router contracts or centralized services.


Team Background

SwaptoX is fully developed by a solo independent Web3 developer.

  • Over 1 year of continuous full-stack Web3 development

  • Built everything from scratch:

    • Smart contracts

    • Routing & pricing engine

    • UI / frontend

    • Token-to-USD pricing infrastructure

  • Over the past 6+ months, tens of thousands of swap simulations and real transactions have been executed and verified to ensure:

    • Routing correctness

    • Execution safety

    • Contract stability

This is not a prototype-stage project, but a battle-tested system already running in production.

Timeline

Month Milestone
Month 1 Milestone 1 – Rootstock deployment
Month 2 Milestone 2 – Swap Mini SDK
Month 3 Milestone 3 – Public API & Docs

Technical Specs

  • Architecture: Modular swap aggregator

  • Routing: 1–3 hop optimal path discovery

  • Pricing: Precise pricing engine, including fee-on-transfer token handling

  • Contracts: Custom-built (no dependency on heavy routers)

  • Frontend: Lightweight, responsive UI

  • Infrastructure: Independent token-to-USD pricing system (on-chain + off-chain mapping)


Value Proposition for Rootstock

Rootstock currently lacks a general-purpose, developer-friendly swap aggregation infrastructure.

SwaptoX provides Rootstock with:

  • A production-ready swap aggregator

  • SDKs that reduce development costs for ecosystem projects

  • APIs enabling BTCFi derivatives, bots, and advanced DeFi use cases

  • A long-term infrastructure component, not a short-lived DApp

This directly strengthens Rootstock’s BTCFi and DeFi composability with minimal upfront ecosystem cost.


Demo & project


Closing

SwaptoX is already a functioning, production-deployed swap aggregator that has proven its technical feasibility over months of real usage. With Rootstock’s support, SwaptoX can become a native BTCFi infrastructure component, enabling faster ecosystem growth and easier DeFi integration for future builders.

Hi @SwaptoX I have a few questions and would appreciate some additional clarity on your proposal:

  1. Which Rootstock-native tokens and liquidity pools are you envisioning supporting initially?
  2. Have you evaluated the existing DEXs that already support Rootstock swaps? If so, what would meaningfully differentiate your approach from what’s currently available?
  3. When you reference supporting 30+ tokens at initial deployment, which specific assets are you referring to?
  4. Which websites and dApps are you proposing to target with the mini-SDK, and what criteria are you using to select them?

Looking forward to your responses.

Hi @axia , thanks for the questions. I’m happy to clarify.

1. Initial tokens and liquidity pools on Rootstock

Based on my observation of the current Rootstock ecosystem, there is meaningful liquidity on WoodSwap and Sushi. Across these two DEXs, there are roughly ~30 active tokens, which would be the initial scope for SwaptoX integration.

Relevant references:

From a user perspective, swapping through an aggregator can theoretically produce better outputs than swapping directly on a single DEX, because a DEX routes only through its own liquidity, while an aggregator evaluates liquidity across the entire chain and multiple paths.


2. Existing swap solutions and differentiation

I also noticed CrowdSwap in the Rootstock ecosystem. However, it is unclear whether CrowdSwap functions as a true on-chain swap aggregator or primarily as a bridge-based solution.
Even on mature chains like Base, CrowdSwap only exposes around 20 tokens, which suggests its focus may not be deep on-chain liquidity aggregation.

In contrast, SwaptoX is purpose-built to optimize swap output. On Base, we currently support 600+ tokens, and the project originated from an arbitrage system, which shaped our routing logic.

Our swap process includes:

  • Collecting liquidity across all available pools

  • Sorting and filtering liquidity pairs

  • DFS-based search across all possible closed-loop paths

  • Batch price quotation to identify the best achievable output

This is why, in practice, swapping through SwaptoX can outperform direct swaps on individual DEXs.


3. “30+ tokens” at initial deployment

The “30+ tokens” refers specifically to the assets currently available through WoodSwap and Sushi on Rootstock, as listed in the pool links above. These would form the initial supported token set at launch.


4. Mini-SDK targets and use case

The Mini-SDK is designed for DEXs, dApps, and applications that already have user traffic but lack native swap logic.

For example:
If a dApp’s primary token is USDT, but a user only holds ETH, the typical flow today is to redirect the user to WoodSwap or Sushi to manually swap ETH → USDT.

By integrating the SwaptoX Mini-SDK, the dApp can enable this swap directly within its own interface, without sending users away, improving both UX and conversion.


Finally, if SwaptoX is integrated on Rootstock, we are committed to offering at least one year of free usage for Rootstock users, including Swap functionality, Mini-SDK, and API access.

@axia Test video: https://youtu.be/g7lfSBdg3Ws

I shared a simple comparison video: SwaptoX vs Uniswap and SwaptoX vs KyberSwap.
From this test, two observations can be made:

  1. In most cases, using a swap aggregator can produce better outputs than swapping directly on a single liquidity DEX. This is the fundamental reason why platforms benefit from having an aggregator layer.

  2. Based on observed results, the gap between SwaptoX’s arbitrage-based routing logic and a mature aggregator like KyberSwap is relatively small, which highlights SwaptoX’s cost-effectiveness as an infrastructure solution.
