Implement Stellar-to-Ethereum Cross-Chain Bridge Contract

[akargi]

Overview

Design and implement a Soroban smart contract that enables secure asset bridging between Stellar and Ethereum blockchains through wrapped token mechanics and multi-validator attestation.

Description

Cross-chain interoperability is critical for InterChangableTrade ecosystem expansion. This contract enables users to lock native Stellar assets and receive equivalent wrapped tokens on Ethereum (and vice versa) through a decentralized bridge infrastructure using Soroban's native capabilities.

Requirements

• Wrapped token contract on Stellar for Ethereum-originated assets
• Asset locking mechanism with validator attestation
• Token minting upon successful lock verification
• Token burning and asset unlock mechanics
• Multi-signature validator consensus (m-of-n threshold)
• Cross-chain event emission and indexing
• Bridge liquidity reserve management
• Fee collection and distribution
• Emergency pause and recovery mechanisms
• Chain-specific configuration parameters

Direction

The implementation should:

• Use Soroban SDK for smart contract development
• Implement secure validator attestation pattern
• Maintain 1:1 asset collateralization
• Support multiple asset types (native XLM, Stellar assets, Ethereum tokens)
• Enable transparent fee structure
• Provide emergency withdrawal mechanisms
• Maintain immutable bridge event history

Acceptance Criteria

• Soroban contract deploys successfully with Stellar CLI
• Wrapped token contract created with standardized interface
• Asset lock triggers validator attestation collection
• Wrapped tokens mLet me check the repository structure:
