import {
construct,
methods,
} from '@substrate/txwrapper-polkadot';
const unsigned = methods.balance.transfer(
{
dest: 'FoQJpPyadYccjavVdTWxpxU7rUEaYhfLCPwXgkfD6Zat9QP',
value: 100,
},
{
// Additional information needed to construct the transaction offline.
}
);
const signingPayload = construct.signingPayload(unsigned, { registry });
// On your offline device, sign the payload.
const signature = myOfflineSigning(signingPayload);
// `tx` is ready to be broadcasted.
const tx = construct.signedTx(unsigned, signature, { metadataRpc, registry });
Have a look at the examples to see how you can perform the whole lifecycle of a transaction, from generation to signing to broadcast.
