nhussein11 · nhussein11 · commit 2a1a659b7644 · 2025-12-17T18:30:41.000-03:00
- Changed RPC URL from 'https://testnet-passet-hub-eth-rpc.polkadot.io' to 'https://services.polkadothub-rpc.com/testnet' across multiple files. - Updated chain ID from 420420422 to 420420417 in relevant configurations and documentation. - Adjusted deployment outputs and examples to reflect the new network settings. - Removed outdated faucet GIF and updated references in documentation for clarity.
