Docs - Create comprehensive Supported Chains & Currencies documentation

[MantisClone]

Problem

The Supported Chains & Currencies page lacks comprehensive information about what chains and currencies are supported by Request Network. Multiple use case pages link to this resource, but it needs expansion.

Proposed Solution

Create comprehensive documentation at /resources/supported-chains-and-currencies covering:

• All 9 supported EVM chains with details
• 150+ supported currencies/tokens per chain
• Token addresses and contract details
• Network-specific considerations
• Testnet availability
• Conversion payment support per chain
• Cross-chain payment capabilities

Considerations

• Research actual supported chains/currencies from request-api codebase (/request-api/src/currencies/)
• Verify with EasyInvoice currency/chain selectors for accuracy
• Present data in scannable format (tables, grouped lists)
• Include both mainnet and testnet information
• Link from multiple Use Case pages (already in place)
• Keep updated as new chains/currencies are added

Note

Recently updated from 10 chains to 9 chains (Fantom deprecated via Alchemy).
