Multi-chain DEX aggregator
Non-custodial · no native token

Every order, split for the best executable price.

Fibrous is a multi-chain DEX aggregator. It scans the liquidity on Starknet, Base, HyperEVM or Monad, splits each order across venues and routes, and settles it in one transaction from your own wallet.

How routing works
Five components, one transaction

What happens between your quote and your fill

As you type an amount, the interface reads fresh onchain snapshots and the Path Solver evaluates candidate paths in real time. The Swap button turns active only when the trade is ready.

  1. 01

    Blockchain indexer

    Keeps onchain pool and token data up to date.

    Pools and tokens
  2. 02

    Graph API

    Makes that data clean and ready for routing.

    Routable market data
  3. 03

    Path Solver

    Determines the route and price, splitting the order where that pays.

    89% direct · 11% via cbBTC

    API & SDK

    Return a quote and ready-to-execute calldata in one request.

    /v2/routeAndCalldata
  5. 05

    Aggregation Router

    Executes the selected route onchain in a single transaction.

    1 transaction
When you press Swap

Fibrous refreshes the quote on the latest block, estimates gas and applies a short validity window.

If the minimum isn’t met

The transaction is cancelled, so it does not execute at an outdated price.

Approvals

You sign an approval first. Where EIP-7702 or ERC-4337 smart accounts are enabled, it can go in the same transaction.

Fibrous routing for AI agents

FibX is a CLI and an MCP server that let AI agents quote, swap and transfer on Base, HyperEVM and Monad, and use Aave V3 on Base, through Fibrous routing. You press Simulate and Swap; the agent doesn’t.

An agent’s request becomes a Fibrous route. A local signing policy the user owns is enforced before every signature. Route shown as an example.

Introducing FibX: Best DeFi Execution for AI Agents

AI is getting exponentially more capable. Agents from Claude to OpenAI, and from Cursor to custom LLM workflows, can reason, plan, and make decisions at a level that was unimaginable just two years ago. But intelligence without execution is just theory. Until now, connecting an AI agent to real DeFi operations meant building custom integrations, managing complex wallet infrastructure, and writing brittle onchain scripts by hand. This changes today. We are excited to announce FibX, a CLI-based

Fibrous on Monad: Unifying Liquidity for Peak Performance

Monad combines high speed and parallel execution with EVM compatibility, creating a new building block for performant applications. But speed alone does not guarantee a good trading experience. In the early stages of any chain, liquidity is scattered across multiple protocols, pool depth varies, and the same asset can show different prices from venue to venue. No matter how fast the chain is, trading execution quality still depends on liquidity. Enter Fibrous. We provide the layer that complete
