`
An example: `signMessage({nonce: 1234034, message: "Welcome to dapp!", address: true, application: true, chainId: true })`
This would generate the `fullMessage` to be signed and returned as the `signature`:
```typescript
APTOS
address: 0x000001
chain_id: 7
application: badsite.firebase.google.com
nonce: 1234034
message: Welcome to dapp!
```
### dApp Integration
dApps can make requests to the wallet from their website:
* `connect()`: prompts the user to allow connection from the dApp (*neccessary to make other requests*)
* `isConnected()`: returns if the dApp has established a connection with the wallet
* `account()`: gets the address of the account signed into the wallet
* `signAndSubmitTransaction(transaction)`: signs the given transaction and submits to chain
* `signTransaction(transaction)`: signs the given transaction and returns it to be submitted by the dApp
* `disconnect()`: Removes connection between dApp and wallet. Useful when the user wants to remove the connection.
// import transaction build from aptos sdk: https://github.com/aptos-labs/aptos-core/tree/main/ecosystem/typescript/sdk
import { BCS, TxnBuilderTypes } from 'aptos';
// Establish connection to the wallet
const result = await window.aptos.connect()
// OR
const result = await window.coin98.aptos.isConnected()
// Check connection status of wallet
const status = await window.aptos.isConnected()
// OR
const status = await window.coin98.aptos.isConnected()
// Gets the address of the account signed into the wallet
const accountAddress = await window.aptos.account()
// OR
const accountAddress = await window.coin98.aptos.account()
// Create a transaction
const transaction = {
arguments: [address, '717'],
function: '0x1::coin::transfer',
type: 'entry_function_payload',
type_arguments: ['0x1::aptos_coin::AptosCoin'],
};
// Send transaction to the extension to be signed and submitted to chain
const response = await window.aptos.signAndSubmitTransaction(transaction)
// OR
const response = await window.coin98.aptos.signAndSubmitTransaction(transaction)
// Send transaction to the extension to be signed and returns
const signedTransaction = await window.aptos.signTransaction(transaction)
// OR
const signedTransaction = await window.coin98.aptos.signTransaction(transaction)
// Disconnect dApp from the wallet
await window.aptos.disconnect(transaction)
// OR
await window.coin98.aptos.disconnect(transaction)
### Verify signature:
```javascript
const signMessage = async () => {
const result = await window.aptos.signMessage({
nonce: 3885,
message: 'Click to sign in and accept the BlueMove Terms of Service. This request will not cost any gas fees.',
address: true,
application: true,
chainId: true
})
setState(state => ({ ...state, message: result }))
}
const verifyMessage = () => {
const { message, account } = state
const sig = message.signature
const pub = account.publicKey
const fullMessage = message.fullMessage
const signature = Buffer.from(sig.substring(2), 'hex')
const pubKey = Buffer.from(pub.substring(2), 'hex')
const verify = Nacl.sign.detached.verify(Buffer.from(fullMessage), signature, pubKey)
alert(verify)
}
```
