Notes

Assets may appear on multiple chains with the same symbol but different addresses
The runtime field helps determine which wallet type is needed (EVM wallet vs Solana wallet)
Use the decimals field to properly format amounts when displaying to users or constructing quote requests
The m0Extension field identifies tokens that are part of the M protocol ecosystem
