# Non-EVM Chain Support

This document outlines the architecture for supporting non-EVM chains (Solana, Cosmos) in ASLE.

## Architecture Overview

### Bridge Adapters

The system uses a bridge adapter pattern to support different blockchain architectures:

1. **EVM Chains**: Uses Chainlink CCIP
2. **Solana**: Uses Wormhole bridge
3. **Cosmos**: Uses IBC (Inter-Blockchain Communication)

### Components

#### 1. Bridge Adapter (`bridge-adapter.ts`)
- Base interface for all bridge adapters
- Factory pattern for creating adapters
- Handles cross-chain messaging

#### 2. Solana Adapter (`solana-adapter.ts`)
- Integrates with Solana programs
- Uses Wormhole for bridging to/from EVM chains
- Handles Solana-specific operations (pools, liquidity)

#### 3. Cosmos Adapter (`cosmos-adapter.ts`)
- Integrates with Cosmos SDK
- Uses IBC for cross-chain communication
- Handles Cosmos-specific operations

#### 4. Cross-Chain Manager (`cross-chain-manager.ts`)
- Orchestrates cross-chain operations
- Manages adapter instances
- Handles message routing

## Implementation Status

### Solana
- [x] Bridge adapter structure
- [x] Wormhole integration interface
- [ ] Solana program deployment
- [ ] Full liquidity pool implementation
- [ ] Testing on devnet

### Cosmos

## Next Steps

1. **Solana Program Development**
   - Create ASLE Solana program
   - Implement liquidity pool logic
   - Integrate with Wormhole

2. **Cosmos SDK Module**
   - Create ASLE Cosmos module
   - Implement IBC handlers
   - Integrate with existing Cosmos chains

3. **Testing**
   - Unit tests for adapters
   - Integration tests with testnets
   - End-to-end cross-chain tests

4. **Documentation**
   - API documentation
   - Deployment guides
   - User guides
