This proposal registers the Phala Network (PHA) token and enables cross-chain transfers to Ethereum via Hyperbridge.

Steps

1. Register Token Metadata
   Call assetRegistry.registerTokenMetadata to add PHA locally
   (Decimals: 18, aligned with ERC-20)
2. Enable Hyperbridge Support
   Call TokenGateway.CreateErc6160Asset to register PHA for cross-chain bridging

Outcome
• PHA is available as a local asset
• PHA can be bridged between the local chain and Ethereum via Hyperbridge
