Fragmented Liquidity: Users struggle to find the best swap rates when liquidity is scattered across chains. This results in high slippage and suobtimal prices.
Cross-Chain Complexity: Manually swapping assets across chains involves, researching prices/liquidity on multiple chains, calculating splits for optimal routing, executing separate bridge and swaps transactions. The process is slow, painful and error-prone. And most of the time, the price and the liquidity is gone before the user finalizes the swap.

agent9000 is an intent based, cross-chain swap protocol that unifies fragmented liquidity across all networks on the OP-Stack. By combining agentic AI, algorithmic routing, and Optimism’s Superchain interoperability layer, it abstracts cross-chain complexity into a single chat message and a single transaction that takes less than 5 secs.

“gm! please swap 20 ETH to USDC”→ agent9k handles the rest (we also have a boomer interface but who needs that?)

agent9000 consists of 3 main components:

1. SuperSwapper: The SuperSwapper contract integrates several key components from Optimisim Superchain interop. It uses Superchain Token Bridge to enable cross-chain token transfer functionality, L2-to-L2 Cross Domain Messenger to enable cross-chain function calls, Uniswap to power token swapping on each chain and a failed swap recovery mechanism that ensures users can always recover their assets in case any of the cross-chain swaps fails due to new market conditions.
   SupperSwapper bridges tokens to the destination chain, sends a cross-chain message to initiate the swap on the destination, executes the swap through a crosschain-message and returns resulting tokens back to the user's address on the source chain. Failed swaps are recorded on each chain, users can withdraw failed swaps from any chain.
2. agent9000: a9k is an intent based AI agent built with Coinbase AgentKit. It chats with the user and translates user intents (e.g., “Swap 20 ETH to USDC”) into cross-chain swap transactions. On the background, it uses an Advanced Routing Engine to find the optimum split across all chains in the superchain network.
3. Routing Engine: Routing engine polls prices and liquidity from integrated DEXs and uses Equal Marginal Price Algorithm to dynamically split swaps across chains/DEXs to minimize slippage and maximize output.

1. Truly Native Cross-Chain Execution via Optimism Superchain
   a9k leverages Optimism’s native interoperability to execute swaps, bridging, and settlements at native speed and robustness.
   vs. Competitors:
   Projects like SquidRouter takes 30 minutes or more to execute a simple crosschain swap.

2. Chat-First, Intent-Driven UX
   agent9000 is one of the first cross-chain defi projects to use a conversational AI interface (powered by Coinbase Agent Kit). Users describe swaps in plain language (e.g., “Swap 20 ETH to USDC”), and the agent handles the rest—no manual chain/DEX selection or wallet switching. agent9000 abstracts all complexity into a single message.
   vs. Competitors:
   Projects like 1inch or LI.FI may need users to manually select chains, tokens, and approve multiple transactions.

3. Equal Marginal Price Algorithm
   A proprietary algorithm that mathematically guarantees optimal swap splits across chains and DEXs by ensuring marginal prices for the next unit traded is equal across all DEXes. agent9000 dynamically balances splits based on real-time liquidity across all OP Stack chains.
   vs. Competitors:
   Aggregators like THORChain or ParaSwap optimize for single-chain routes or basic multi-chain splits.

We built a full working prototype, not a toy, running on 4 different OP mainnet forks (Optimism, Base, Unichain, Mode) given that the OP superchain interop infra is only available on devnets.

Our time was limited so we needed to make some compromises:

• Focused on a single pair(ST9000<->SWETH) via Uniswap
• No MEV protection.
• No support for non-super tokens.
• Supports limited actions through chat, no complex queries yet

Why It Works
Proved core functionality: intent based chat interface → optimized cross-chain split → instant native-like cross-chain swaps with unified liquidity.

Next Steps
Expand tokens/dexes, dynamic slippage, MEV protection, auto-retries, cross-chain yield optimization, etc.
