No description provided.

Maybe can rename this field disabled_transfer_banner_config for more clarity.

[sarah-thong]

1. Please rename this field to unsupported_tokens
2. Please revise this description to List of tokens that are no longer supported
3. Please add a note stating that The token denoms listed here **MUST** match the token denoms listed under the Carbon [Tokens API](https://api.carbon.network/carbon/coin/v1/tokens?pagination.limit=10000)..

[sarah-thong]

1. Pls rename this field to temp_disabled_transfer_tokens
2. Please add a note that The token denoms listed in this object **MUST** match the token denoms listed under the Carbon [Tokens API](https://api.carbon.network/carbon/coin/v1/tokens?pagination.limit=10000).

[sarah-thong]

1. Pls rename this field to temp_disabled_bridges
2. Please add a note that Blockchain network listed here **MUST** match the valid chainName of the bridges listed under BridgeAll RPC call.<br /><br /> To view the values of BridgeAll RPC call, simply run yarn get-bridges [network]on the command line. Sample for mainnet:yarn get-bridges mainnet``

Think instead of assigning start and end to empty strings, would be good to make both fields optional, then you just need to make it an empty object.
i.e.

{
  "temporary_disabled_transfer_tokens": {
    "token_1": {}
  }
}

Please add a check for no_longer_supported_tokens to make sure that all the token denoms are valid. Please refer to this code snippet to see how to check if denoms are valid.

[sarah-thong]

1. I see Object.keys(temporary_disabled_transfer_tokens) is used twice, pls store this in a variable and apply where necessary.
   i.e.

const disabledTokenKeys = Object.keys(temporary_disabled_transfer_tokens)
if (disabledTokenKeys.length > 0) {
  disabledTokenKeys.forEach((key) => { ... })
}

2. Pls check that each denom key is valid. Please refer to this code snippet to see how to check if denoms are valid.

[sarah-thong]

Pls revise the message to ERROR: ${network}.json has an invalid end time (${end}) as it is before start time (${start}) for token denom ${key}.

• Don't we already have another field transfer_disabled_tokens to temporarily disable token transfers. Pls choose 1 and remove the other 1 for this PR.
