feat: add AssetRegistry for multi-asset symbol-based token lookup#3
Conversation
Add AssetRegistry class (TS + Python) that maps (network, symbol) to token metadata, enabling B-form shorthand where developers specify assets: ["USDT", "USDC"] instead of manual addresses/decimals. - New AssetRegistry with built-in tokens for EVM (eip155:1/56/97) and TRON (mainnet/shasta/nile) networks - convertMoney utility for Money → smallest-unit conversion - Global singleton (globalAssetRegistry / global_asset_registry) - ResourceConfig and PaymentOption gain optional assets field - x402ResourceServer auto-expands B-form to D-form PaymentRequirements - 25 TS + 25 Python unit tests for registry and conversion
- Fix import ordering in __init__.py - Remove unused AssetInfo import in server_base.py - Collapse unnecessary multi-line expressions per ruff format
Internal test tokens no longer needed in the built-in registry.
