Welcome to the Argos Protocol V1, an innovative platform designed to revolutionize cross-chain swaps by integrating Uniswap V4 and Across Protocol technologies. Argos Protocol embodies a seamless, efficient, and secure method for transferring assets across different blockchain networks.

Uniswap V4, a cornerstone of Argos Protocol, is a cutting-edge Automated Market Maker (AMM) protocol. Key aspects include:

• Non-custodial, Non-upgradeable, Permissionless: Built on the Ethereum Virtual Machine (EVM), it offers robust security and user autonomy.
• Advanced Features: Incorporates architectural enhancements over previous versions (V1, V2, and the concentrated liquidity model in V3).
• Innovative Capabilities: Includes hooks, singleton, flash accounting, and native ETH support for an optimized trading experience.

Across Protocol complements Argos by providing a trust-minimized bridge. Its features are:

• Secure Asset Transfer: Utilizes a network of relayers and an Optimistic Oracle for secure, efficient transfers between Ethereum and its Layer 2s.
• UBA Fee Model: Balances liquidity across chains, enhancing the efficiency of cross-chain interactions.

Argos Protocol V1 leverages Uniswap V4 and Across Protocol to facilitate efficient cross-chain swaps:

1. Initiation: User starts a swap on Chain A in a Uniswap V4 pool integrated with Argos's Cross-Chain Swap Hook.
2. Bridge Transfer: The beforeSwap hook on Chain A initiates a bridge transfer to Chain B via Across Protocol.
3. Relayer Interaction: Across Protocol relayers provide equivalent tokens on Chain B.
4. Execution and Completion: Swaps are executed on Chain B, followed by afterSwap actions on both chains.
5. Optimistic Oracle Verification: Ensures the validity of the swap and relayer reimbursement.

While Argos Protocol V1 marks a significant milestone, we are actively addressing these challenges:

• Balance Delta Handling: Ensuring zero balance delta at the end of transactions on each chain.
• Gas Costs: Optimizing transactions to reduce gas fees associated with cross-chain transfers.
• Liquidity Pool Balance: Maintaining equilibrium in liquidity pools to prevent slippage and other issues.
