About

Txwrapper library for axia relay and system chains; specifically AXIA, Kusama, Rococo, Westend, Statemint and Statemine.

Note: not all methods available apply to all supported chains. To check what methods are supported by a chain consult the pallets included in chain's runtime.

Get Started

yarn add @axia-core/txwrapper-axia

In a JS/TS file:

import {
  construct,
  methods,
} from '@axia-core/txwrapper-axia';

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.
