Introduction to the Ecosystem
Are you ready to build critical infrastructure for the next generation of DeFi on Stellar As liquidity management becomes increasingly complex across decentralized exchanges we need sophisticated execution layers that can bridge advanced algorithms with on-chain operations.
At Lobster Protocol were developing a comprehensive liquidity optimization solution funded by the Stellar Community Fund. Our data-driven approach analyzes DEX pools in real-time identifying optimal strategies for liquidity providers. Weve already built successful solutions across Arbitrum and BNB Chain and now were bringing our expertise to Stellars growing ecosystem.
This is your opportunity to build the smart contract infrastructure that will transform how liquidity flows through Stellar DEXs. Youll create the critical execution layer that connects our proven optimization algorithms with on-chain operations directly impacting capital efficiency across the ecosystem.
Why Lobster
The Stellar ecosystem presents a unique opportunity with its built-in DEX native multi-asset support and efficient consensus mechanism. Unlike EVM chains Stellar offers native order books and path payments enabling sophisticated liquidity strategies without the overhead of complex smart contracts.
Our solution leverages these Stellar-specific advantages while adding an intelligent optimization layer through Soroban smart contracts. By combining Stellars native efficiency with advanced algorithms were creating infrastructure that couldnt exist on other chains.
Build Soroban Smart Contracts:
Develop WASM-compiled smart contracts using Rust and the Soroban SDK. Implement secure validation for liquidity operations including XLM and token deposits/withdrawals. Create contracts that interface with Stellars native DEX and handle path payments efficiently. Ensure proper integration with Stellars account and trustline system.
Develop Stellar Integration Layer:
Build the infrastructure to connect our off-chain algorithms with Soroban contracts via Horizon API and Soroban RPC. Implement transaction building and signing mechanisms that respect Stellars sequence number requirements. Handle Stellar-specific operations like trustline management and path payment optimization.
Optimize for Stellars Architecture:
Design contracts that minimize storage costs on Stellars ledger. Implement efficient data structures considering Stellars fee model. Ensure contracts work seamlessly with Stellars native multi-asset support and built-in DEX functionality. Optimize for Stellars 5-second block time.
Deploy to Stellar Network:
Handle deployment through Stellars testnet (Futurenet for Soroban) with comprehensive testing. Execute mainnet deployment following Stellar Foundation recommendations. Configure proper network settings and monitor contract performance using Stellar-specific tools.
