Creating and more signatures 2-of-3 transactions involve more steps:
Preliminary conditions
Before you continue, make sure you have the following:
- A private key for your Ethereum wallet.
- An Ethereum address that can sign transactions (« signing address »).
- Several signatures from different accounts or wallets that will be used to check these signatures.
Step by step instructions
Here is a step-by-step guide on creating a multi-security 2-OF-3:
1. Define the transaction
A 2-EF-3 multi-signature transaction can involve several signatories contributing with private keys to this transaction. Each signatory adds a unique message that will be used for verification.
2. Create a multi -signal wallet (optional)
Wallet, consider creating one:
. This will generate a new private key and a public address that can be used as more signatories.
.
3. Add signatures to transaction
Create a transaction using your signal address.
`JavaScript
Consist transaction = {
From: 'signatory1',
At: "signatory2",
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // replace with real data, for example, "0x1234567890ABCDEF"
};
Consist signatures = [
{
From: 'signatory3',
At: "signatory2", // must be different from the address "La" in the transaction
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // replace with real data, for example, "0x1234567890ABCDEF"
},
{
from: 'signatory1', // can be any of the signatories
At: signatory3, // must be different from the "La" address in the transaction
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // replace with real data, for example, "0x1234567890ABCDEF"
},
{
from: 'signatory2', // can be any of the signatories
to: signatory1, // must be different from the address "La" in the transaction
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // Replace with real data, for example, "0x1234567890ABCDEF"
}
];
4. Sign transaction
Create a new transaction using theEthereum-Gascommand and add the signatures from Step 3.
JavaScript
Const {eth} = requires ('ethereum-wallet');
Const tx = {
To: signatory1,
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // replace with real data, for example, "0x1234567890ABCDEF"
};
// sign the transaction
Const -semnature = eth.signtx (tx);
console.log (signature);
Multi-signed wallet configuration
If you have created a multi-sign wallet, use it to sign transactions. Here's an example:
JavaScript
const {sign} = requires ('ethereum-wallet');
CONST Signingaddress = '0x ... Your Signer1 address ...';
// ...
Const tx = {
From: Signingaddress,
To: Signer2,
Value: '10 Eter ',
Gas: 20000,
Gasprice: 20,
Data: '0x ... Your Ethereum data ...' // replace with real data, for example, "0x1234567890ABCDEF"
};
// sign the transaction
Const -signature = sign (tx);
console.log (signature);
