Signing of the transaction Using Metamask at React Using Using PurletConnect
Because your DAPP is becoming more complex, it is necessary to integrate On poplar soolation is Metamask, ap. In this article, we will give examine How to sign transactions at React Using PurletConnect.
first steps from Portonnect
To use Walletconnect, you need to install
- React-Native-Walletconnect
(React Native Library)
- Metamask portfolio (download and install it prior [Metamask website] (
After infrastructure, import and initiate the element of the react:
Jsx
Import {Connect} with "React-Native";
Import Walletconnect With "@react-native-native-native";
Const ConnectedApp = ({signedx}) => {
return (
);
};
signing transactions with metamask
To sign a transaction, you must:
4
`Jsx
Import {Connect} with "React-Native";
Import Walletconnect With "@react-native-native-native";
Const ConnectedApp = ({signedx}) => {
Const [wallet, setwallette] = Usestate (null);
Useeffect (() => {
if (signedtx) {
Setwallet (Waletconnect.createprovider (
Portfonnect.et,
"You-Metamask-Credentals", // Reples your Metamas certifications
)));
}
}, [signedtx]);
return (
{wallet && (
)}}
);
};
In this example, we are “Talletconnect.createprovider” to the crate a supplier’s for the Etherum network. That’s the provide of Metamask certifications as the supplier’s opting.
Service of signed transactions
When the user signs the transaction, you can it the SIGNEDTX object to perform varius action in blockchain:
* Send a transaction : call signedtx.send () to send a signed transaction.
* Download the dedeals of the transaction
: Usesignedtx.GetransactionDetals () to download transaction details (e.g. hash, block numbers).
* Check that transaction has been confirmed : Usesignedtx.istransactiononchain () to check that way that transacted or confirmed.
Here is an example of the code to start:
`Jsx
const signedtransaction = async () => {
Const signedtx = areres for exportedprovider?;
to try {
// Send a signed transaction
Wait for signedtx.send ();
console.log ("transaction'sent");
} catch (error) {
console.error (error);
}
};
SIGNEDRANSACTION ();
security considerations
When using Metamask, you hold always keep the security of the certifications. The Make of Sure:
- Store Metamask’s certifications safifyly.
- Share the necessary certifications to users.
- Regional Metamas certifications regularly to remain.
By following thees and examples, you can integrate the portfonnec with the name of the name of the DAPP React in integrate to Remember to safely the signed transactions and theem responsibly.
