SDK Technical Feasibility

Muwp Stellar MultiToken CrossChain SDK

Purpose: The Muwp SDK simplifies cross-chain interactions for Stellar developers by enabling seamless multi-token swaps and integrations with Stellar's ecosystem. This SDK is tailored to address challenges in building interoperable applications while keeping Stellar and XLM at the core of operations.

Technical Strategy

1. SDK Core Development

• Objective: Provide developers with essential tools to integrate multi-token swaps and cross-chain functionality into their Stellar-based applications.
• Key Features:
  • Multi-Token Routing System: Optimal pathfinding for token swaps across DEXes and liquidity pools.
  • API Endpoints: Simplified methods for asset management, swap execution, and cross-chain integrations.
  • Seamless Interoperability: Supports cross-chain swaps with tokens external to Stellar, converting them efficiently into XLM.

2. Smart Contract Integration with Soroban

Soroban smart contracts manage advanced routing logic, swap execution, and liquidity optimization.

#[contract]
pub trait SwapContract {
    fn execute_swap(&self, env: Env, from_token: Symbol, to_token: Symbol, amount: BigInt);
}

pub struct SwapImpl;

#[contractimpl]
impl SwapContract for SwapImpl {
    fn execute_swap(&self, env: Env, from_token: Symbol, to_token: Symbol, amount: BigInt) {
        let price_feed_contract: PriceFeedContractClient = env.get_contract("price_feed_address");
        let from_price = price_feed_contract.get_price(env.clone(), from_token);
        let to_price = price_feed_contract.get_price(env.clone(), to_token);

        // Calculate optimal swap route
        // Execute swap on Stellar's DEX
    }
}

• Price Feeds: Fetch real-time token prices for accurate routing.
• Routing Logic: Calculate the best swap route and execute it using Stellar's DEX or external bridges.
• Optimization: Automate decision-making for the most cost-effective and efficient swaps.

3. Cross-Contract Calls

Enable the SDK to interact with liquidity and price-fetching contracts seamlessly.

#[contract]
pub trait LiquidityContract {
    fn add_liquidity(&self, env: Env, token_a: Symbol, token_b: Symbol, amount_a: BigInt, amount_b: BigInt);
}

pub struct LiquidityImpl;

#[contractimpl]
impl LiquidityContract for LiquidityImpl {
    fn add_liquidity(&self, env: Env, token_a: Symbol, token_b: Symbol, amount_a: BigInt, amount_b: BigInt) {
        // Logic to add liquidity
    }
}

---

4. Integration with DEXes and Bridges

• DEX Integration: Interact with Stellar-native DEXes like StellarX and StellarTerm.
• Bridge Support: Integrate with services like Allbridge for non-Stellar tokens.

Integration Strategy:

1. Horizon API — Query account details, submit transactions, and monitor swaps.
2. Soroban Contracts — Automate routing and liquidity checks.
3. External APIs — Connect with platforms like Changelly for external token swaps.
