console.log(addr, 'result = ',  res)
// 3PHictxPg9gCLbSuwnvDhPtm9xkAM32Xs4 result =  [ 'btc' ]

// an invalid ethereum like address
addr = '0x3PHictxPg9gCLbSuwnvDhPtm9xkAM32Xs4'
res = await CryptoDetector.detect(addr)
console.log(addr, 'result = ',  res)
// 0x3PHictxPg9gCLbSuwnvDhPtm9xkAM32Xs4 result =  null

// a valid ethereum compatible address
addr = '0xea674fdde714fd979de3edf0f56aa9716b898ec8'
