Distributed Signature Generation
The full signing example is here.
Let's create NetworkSigner for signing. Note the EphAuth is used to avoid user interaction when generating the signatures.
const authModule = new EphAuth(accountsFromBrowserWallet[0], ephSK!);
// Create a new signer instance
const sdk = new NetworkSigner(wpClient, threshold, partiesNumber, authModule);
Use the NetworkSigner.authenticateAndSign method to generate a signature.
let signMessage = JSON.stringify({
userOperation: {
sender: '0x8d4cb2540d993fe34c646299f1ab4af3012ff34c',
nonce: '0x7',
initCode: '',
callData:
'0000189a...',
callGasLimit: '123130',
verificationGasLimit: '153427',
preVerificationGas: '66768',
maxFeePerGas: '',
maxPriorityFeePerGas: '',
paymasterAndData: ''
},
entryPointVersion: 'v0.6.0',
entryPointAddress: '0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789',
chainId: 80002
});
let resp = await sdk.authenticateAndSign(selectedKeyId, signMessage);
The SignResponse contains the signature sign
and the recovery ID recid
.
