Walkthrough

Adds Tron network configuration files to the SDK's currency module. Introduces the Nile testnet configuration with chainId and testnet flag, alongside Tron mainnet configuration with testnet flag and TRC20 token currency mappings (USDT-TRC20 and USDC).

Greptile Overview

Greptile Summary

Added comprehensive support for Tron blockchain to the currency package, enabling the system to handle Tron mainnet and Nile testnet chains.

• Created TronChains class following the established pattern from EvmChains and NearChains, extending ChainsAbstract with Tron-specific chain operations
• Defined Tron mainnet with USDT (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) and USDC (TEkxiTehnzSmSe2XqrBj4w32RUN966rdz8) TRC20 token addresses
• Created Nile testnet configuration as a placeholder for test token definitions
• Added TronChainName type definition and included Tron chains in VMChainName to indicate that payment proxy contracts can be deployed on Tron
• Properly integrated both Tron chains into the declarative chains system and exported TronChains for use throughout the application
• Fixed typo in comment ("Virtual machine" instead of "Virtual machin")

The implementation follows the existing architectural patterns and is consistent with how other blockchain networks are integrated into the system.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation follows established patterns from existing chain integrations (EVM, NEAR), uses consistent type definitions, and adds new functionality without modifying existing code. All changes are purely additive and well-structured.
• No files require special attention
