Description

Add methods to get EVM and Cosmos token balances.

  chains: [1, 43114, 8453]
})

[jmdev3]

Code looks good but the solution don't follow code conventions of the sdk

The idea is for cosmos and emv handlers to expose same method getTokenBalances, please move this service functions inside the handler of each chain

left to return empty array

[genaroibc]

After the try-catch block, it returns cosmosBalances, which is an empty array by default:

const cosmosBalances: CosmosBalance[] = [];
