you have some data in local storage like egld ballance and nonce, but it's best to refresh it using the API

with the signature you can login someone on you dApp. For example if you have a backend in your application and you want to verify that the one who makes the actions on your dApp is the owner of the wallet, you have to verify his signature there

i'm using the component WebWalletLoginButton from DappUI library

cc @constantintovisi @Stan_Sava i've updated to dapp-core 1.2.7 and erdjs 10.2.5 and now it doesn't work on live domain neither on localhost????

for me just "asd" or nothing

@elrondnetwork/erdjs": "9.0.3"

for me it isn't working for about 2-3 weeks, when i first tried it...

i just tried without any token now, the same. The callback url has no signature, only address

just like this: Elrond Web wallet

const transactionStatus = transactionServices.useTrackTransactionStatus({ transactionId: transactionSessionId, })

it's based on nonce number, if you send many transactions at the same time, you have to increment the nonce manually for each transaction, if not, only one transaction will work on one round

func CheckSignature(address string, sig string) bool { _, decodedAddress, _ := bech32.Decode(address) decodedBytes, err := bech32.ConvertBits(decodedAddress, byte(5), byte(8), !true) if err != nil { log.Fatal().Err(err).Msg("Address decode error: ") } token := "asd" prefix := "\x17Elrond Signed Message:\n" message := address + token + "{}" data := []byte(prefix + strconv.Itoa(len(message)) + message) hash := sha3.NewLegacyKeccak256() hash.Write(data) hashedMessage := hash.Sum(nil) decodedSig, _ := hex.DecodeString(sig) verified := ed25519.Verify(decodedBytes, hashedMessage, decodedSig) return verified } here it's my example GO code for validation on backend
