Ethereum → Solana (Wormhole Direct)\n   - Time: ~15 minutes\n   - Cost: ~$10\n   - Receive: wETH (wrapped)\n```\n\n## Contract Addresses\n\n### Stargate\n| Chain | Router |\n|-------|--------|\n| Ethereum | 0x8731d54E9D02c286767d56ac03e8037C07e01e98 |\n| Arbitrum | 0x53Bf833A5d6c4ddA888F69c22C88C9f356a41614 |\n| Optimism | 0xB0D502E938ed5f4df2E681fE6E419ff29631d62b |\n| Polygon | 0x45A01E4e04F14f7A4a6702c74187c5F6222033cd |\n\n### Wormhole\n| Chain | Token Bridge |\n|-------|--------------|\n| Ethereum | 0x3ee18B2214AFF97000D974cf647E7C347E8fa585 |\n| Solana | wormDTUJ6AWPNvk59vGQbDvGJmqbDTdgWgAqcLBCgUb |\n\n## Best Practices\n\n1. **Start Small**: Test with small amounts first\n2. **Verify Contracts**: Always verify bridge contract addresses\n3. **Check Liquidity**: Ensure sufficient liquidity for your amount\n4. **Monitor Status**: Track your bridge transaction\n5. **Understand Risks**: Know the security model of each bridge\n\n## Security Warnings\n\n- **Bridge hacks represent ~40% of all DeFi exploits**\n- Never bridge more than you can afford to lose\n- Verify destination address carefully\n- Be aware of wrapped vs native tokens\n- Some bridges have withdrawal delays\n- Check for any bridge pauses or maintenance\n\n## Common Issues\n\n### Transaction Stuck\n1. Check bridge status page\n2. Verify source transaction confirmed\n3. Wait for finality on both chains\n4. Contact bridge support if > 1 hour\n\n### Wrong Token Received\n- Some bridges use wrapped tokens\n- May need to unwrap manually\n- Check token contract address\n\n### High Slippage\n- Large amounts may exceed pool liquidity\n- Split into smaller transfers\n- Wait for liquidity to rebalance\n\n## Example Queries\n\n1. \"Bridge 1000 USDC from Ethereum to Arbitrum\"\n2. \"Compare bridge options for ETH to Polygon\"\n3. \"What's the cheapest way to bridge to Solana?\"\n4. \"Check status of my Stargate bridge transaction\"\n5. \"Is it safe to use Wormhole for large transfers?\"\n\n## Context Variables\n\n- `{{source_chain}}`: Origin blockchain\n- `{{dest_chain}}`: Destination blockchain\n- `{{token}}`: Token to bridge\n- `{{amount}}`: Amount to bridge\n- `{{bridge}}`: Preferred bridge protocol\n",{"name":5,"tags":47,"author":52,"scripts":53,"version":71,"triggers":72,"composable":54,"parameters":89,"description":7,"persist_state":54,"prerequisites":104},[19,39,48,49,50,51,41],"layerzero","wormhole","stargate","multichain","XSpoonAi Team",{"enabled":54,"definitions":55,"working_directory":70},true,[56,62,66],{"file":57,"name":58,"type":59,"timeout":60,"description":61},"bridge_quote.py","bridge_quote","python",30,"Get bridge quote from multiple protocols",{"file":63,"name":64,"type":59,"timeout":60,"description":65},"bridge_routes.py","bridge_routes","Find optimal bridging routes",{"file":67,"name":68,"type":59,"timeout":60,"description":69},"bridge_status.py","bridge_status","Check bridge transaction status",".\u002Fscripts","1.0.0",[73,79,86],{"type":74,"keywords":75,"priority":78},"keyword",[19,39,48,49,50,51,76,41,77],"transfer","omnichain",90,{"type":36,"patterns":80,"priority":85},[81,82,83,84],"(?i)(bridge|transfer) .*(from|to) .*(ethereum|polygon|arbitrum|optimism|base|solana|bsc)","(?i)(move|send) .*across chains?","(?i)cross.?chain .*(transfer|swap|bridge)","(?i)(layerzero|wormhole|stargate) .*(bridge|transfer)",85,{"type":37,"priority":87,"intent_category":88},95,"cross_chain_bridge",[90,94,97,99,102],{"name":91,"type":92,"required":43,"description":93},"source_chain","string","Source blockchain (ethereum, polygon, arbitrum, etc.)",{"name":95,"type":92,"required":43,"description":96},"dest_chain","Destination blockchain",{"name":31,"type":92,"required":43,"description":98},"Token to bridge (ETH, USDC, etc.)",{"name":100,"type":92,"required":43,"description":101},"amount","Amount to bridge",{"name":19,"type":92,"default":38,"required":43,"description":103},"Bridge protocol to use (stargate, wormhole, layerzero, auto)",{"skills":105,"env_vars":106},[],[107],"RPC_URL","main","3df1d0d67b30ff15236561f8c0f9f06d33f42dfd","skills\u002Fai-crypto\u002Fxspoonai-official-cross-chain-bridge",17,"https:\u002F\u002Fgithub.com\u002Fjiayaoqijia\u002Fcryptoskill","https:\u002F\u002Fgithub.com\u002Fjiayaoqijia","https:\u002F\u002Feth2030.com","Hardcore infra.
