Need utility function for validating address

Agreed.

We use the following code if that may help :

export const isICONAddress = function (address) {
  return /^(hx|cx)?[0-9a-f]{40}$/i.test(address)
}
export const isICONAddressContract = function (address) {
  return /^(cx)?[0-9a-f]{40}$/i.test(address)
}
export const isICONAddressEOA = function (address) {
  return /^(hx)?[0-9a-f]{40}$/i.test(address)
}

Actually I just noticed there are already methods for that implemented in the SDK :

• Validator.isAddress
• Validator.isEoaAddress
• Validator.isScoreAddress
