How to upgrade Redspot？#

Redspot is just a normal npm package, and the upgrade method is the same as other npm packages.

  • npm upgrade：upgrade all dependencies.
  • npm upgrade redspot： Only upgrade Redspot.

If you are using yarn, you can execute the following command to upgrade all dependencies to the stable version.

yarn upgrade-interactive --latest

If you want to use the latest beta version, it is recommended to manually change the version number in package.json and then reinstall the dependencies.

{  "name": "erc20",  "version": "0.1.0",  "private": true,  "dependencies": {    "@redspot/chai": "^0.10.2-1",    "@redspot/gas-reporter": "^0.10.2-1",    "@redspot/patract": "^0.10.2-1",    "@types/chai": "^4.2.14",    "@types/mocha": "^8.0.3",    "chai": "^4.2.0",    "redspot": "^0.10.2-1",    "typescript": "^4.0.2"  },  "scripts": {    "build": "npx redspot compile",    "test": "npx redspot test"  }}

Note When upgrading, it is best to upgrade all plug-ins to the latest version at the same time to avoid dependency problems.

How to specify the version of @polkadot/api and @polkadot/api-contract?#

Redspot internally relies on @polkadot/api and @polkadot/api-contract. If you need to upgrade separately, you can add resolutions in package.json.

/// package.json..."resolutions": {  "@polkadot/api": "4.6.3",  "@polkadot/api-contract": "4.6.3",},...

In this way, you can force the specified version. See package.json for details. However, the compatibility of the upgraded @polkadot/api and @polkadot/contract cannot be guaranteed.

How to access the instance of @polkadot/api in redspot?#

You can access it by network.api.

How to specify the types and RPC of chain in redspot.config.ts?#

Part of the chain can be automatically configured via @redspot/known-types (RPC calls are not supported). It can also be configured manually through redspot.config.ts.

// redspot.config.tsimport { RedspotUserConfig } from 'redspot/types';
export default { ...  network: {    mainnet: {      ...      account: [process.env.ACCOUNT]      types: {        ...      },      rpc: {        europa: {          forwardToHeight: {            description: '',            params: [              {                name: 'height',                type: 'u32'              }            ],            type: 'Bytes'          },        }        ...      }      ...    }  }} as RedspotUserConfig;

What should I do if I cannot call the contract when using erc20-trait?**#

Because erc20-trait has a namespace, you must also add namespace when calling. The example is as follows

// erc20contractFactory.deploy("new", "1000000")// erc20-traitcontractFactory.deploy("baseErc20,new", "1000000")// erc20contract.query.balanceOf(someaddress)// erc20-traitcontract.query["baseErc20,balanceOf"](someaddress)// erc20contract.tx.transfer(receiver.address, 7))// erc20-traitcontract.tx["baseErc20,transfer"](receiver.address, 7))

How to ensure the security of the online private key and avoid uploading to Github?#

You can use environment variables to configure account, as shown in the example below.

// redspot.config.tsimport { RedspotUserConfig } from 'redspot/types';
export default { ...  network: {    mainnet: {      ...      account: [process.env.ACCOUNT]      ...    }  }} as RedspotUserConfig;

Run script

REDSPOT_NETWORK=mainnet ACCOUNT="//Alice" npx redspot run ./scripts/deploy.ts

You can also use tools for example dotenv. In addition, the redspot-explorer plug-in supports signatures using polkadot extensions in the browser.
