API

Network

Currently, there are 3 networks compatible with dio-wallet :


Decimal	Network
1	dioxide main chain network
2	dioxide test chain network
3	dioxide development chain network

RPC

dioxide.request (args：RequestArguments)

Use the request function to submit an RPC request to the wallet and obtain an asynchronous response.

interface RequestArguments {
  method: string;
  params?: unknown\[\] | {\[key: string\]: any};
}
dioxide.request(args: RequestArguments): Promise<unknown>;

The ProviderRpcError will be returned when an RPC call encounters an exception. Please utilize it to retrieve error details.

dioxide.request({
    method: "...",
    params: {...},
})
.then(response => {
    // The result varies by RPC method.
    return response
})
.catch(ex => console.error("ProviderRpcError error",ex))

WalletConnect

WalletConnect is an open-source protocol for connecting DApps to wallets. When invoking this API, it prompts the appearance of a popup window in the wallet, you are required to finish the connection manually within the wallet.

method:


method	params	mandatory	response
request_connect_address	params	optional	string[]

params


name	type	mandatory	description
symbol	string	Yes	only symbol of DApp

Params are optional when the current DApp is an official Dioxide DApp, such as CoreDApp and Testnet Gadgets.
However, if you're an unofficial DApp connecting to the wallet, you must include params.symbol. Dio-wallet will validate the DApp's authenticity on the chain based on the provided symbol.
When Dio-Wallet is in the developer mode, we don't verify the validity of params.symbol. Check here to open developer mode in Dio-Wallet.

Sample:

dioxide.request({
  method: "request\_connect\_address",
  // optional
  params: {
    symbol: "your\_dapp\_symbol"
  }
})
// complete address connection
.then((accounts: string\[\]) => {
    return accounts\[0\]
})
// cancel address connection(eg: close the connection window)
.catch (ex: ProviderRpcError => {
    console.error(ex.code, ex.message, ex.data)
})

Get the wallet address in use within the DApp

When successfully connected to the DApp, a wallet address will be returned. Otherwise, an empty array will be returned.


name	param	response
connected_address	-	string[]

Sample:

const accounts: string\[\] = await dioxide.request({
  method: "connected_address",
})
console.log(accounts\[0\])

Get the blockchain network the DApp is connected to


name	param	response
network	-	NetworkItem

Sample:

interface NetworkItem {
    name: string;
    id: number
}

const network: NetworkItem = await dioxide.request({
  method: "network",
})

console.log(network.id, network.name)

Get the balance of the address in use

Please ensure the address is in use in the DApp. Otherwise, calling this API will result in an Unauthorized (code: 4100) error.


name	param	response
balance	-	string

The decimal precision of DIO is 8. The precision of results obtained through RPC requires manual processing. For instance, "100000000:DIO" represents 1 DIO. We recommend using a library like bignumber.js for accurate floating-point conversion or high-precision calculations when working with balances.

Sample:

const balance:string = await dioxide.request({
  method: "balance",
})

console.log(balance) // output xxxx:DIO

Get the profile details of the address in use (profile)


name	param	response
profile	-	Profile

interface Profile {
  address: string
  avatar: string
  alias: string
}
const profile: Profile = await dioxide.request({
  method: "profile",
})

console.log(profile)

Get the lock screen status of the current wallet


name	param	response
is_locked	-	true(locked) / false(unlocked)

Sample:

const locked: boolean = await dioxide.request({
  method: "is_locked",
})
console.log(locked) // output: true or false

Sign and send transactions


name	param	mandatory	response
send_transaction	params	Y	string

params


name	type	mandatory	description
func	string	Y	contract function name
args	json	N	contract parameter. The specific value varies with the function
delegatee	string	N	proxy address

DApp built-in wallet sending DIO

params.args：


name	type	mandatory	description
Amount	string	Y	transfer amount(1 is 1DIO)
To	string	Y	target address (receiver)

try {
  const txHash: string = await dioxide.request({
      method: 'send_transaction',
      params: {
          func: 'core.coin.transfer',
          args: {
              Amount: “100”, // transfer 100 DIO
              To:'was7fdnfrqh42c7f68pv9s8efmf8y0hv4y6m3h0sgj3ypdfyv09379wh2g:ed25519'
          },
        }
    })
}
catch(ex) {
  if (ex.code === 4001) {
    console.error("User Reject")
    return
  }
  console.error("unexpected error:",ex)
}

Create a token

To create a token, access ‘Tokens' in Core Dapps to facilitate this process.

You can also create a token using the API by configuring the parameters below to define the token's characteristics:

params.args：


name	type	mandatory	description
Symbol	string	Y	Token name（3-8 capital letters - #）
Flags	uint	Y	"1" represents an immutable minter, "0" represents a mutable minter
InitSupply	uint	Y	Initial quantity (default to 0 during creation)
Minter	uint	Y	The cid (contractid) for the token contract can be initialized with a value of 1.
Deposit	string	Y	pre-deposited DIO during initialization (the precision of DIO must be included. If the precision of DIO decimal is 8 digits, the pre stored 1 DIO must be represented as 100000000)
Decimals	uint	Y	Token precision

For example:

const txHash: string = await dioxide.request({
  method: 'send_transaction',
  params: {
      func: 'core.delegation.create_token',
      args:{
          "Flags":1,
          "Minter": 1,
          // pre store 2345 DIO,expression is String(2345 * 10**8)
          "Deposit":"234500000000",
          // 5-digit decimal precision，Initial circulation is 100， Initial expression is String(100 * 10**5)
          "InitSupply": 0,
          "Symbol":"TOKEN1"
          "Decimals": 8
      },
    }
})

const txHash: string = await dioxide.request({
  method: 'send_transaction',
  params: {
      func: 'Asset.TokenManager.mint',
      // If Symbol is ATH and decimal precision is 5, then 3 ATH will be issued additionally, which is expressed as Amount: 3 * 10 * * 5
      args: {
        "amount":"300000",
        "token\_id": "token\_id"
      }
})

        // transfer 200 DIO
        Amount: '200' 
    },
    // If the target address is Token/DApp, delegatee is a required parameter and the value is the current address to be transferred out
    // the connection address of the current wallet must have the management permission of the current address to be transferred out
    delegatee: “TOKEN:token”,
  },
});
console.log("tranasction hash", hash);

Event

JS-API provides a set of built-in event processes, from which you can monitor if the address in use changes.

connected_address_changed

The address in use has changed, triggered by the event of switching the active address in

Dio-wallet.

dioxide.on('connected\_address\_changed', (accounts: string\[\]) => {
// Handle the new accounts, or lack thereof.
// "accounts" will always be an array,
});

network_changed

The blockchain network the DApp is connected to has changed. For example, switching the test network to the development network or the main network in Dio-wallet.

interface NetworkItem {
    name: string;
    id: number
}

dioxide.on('network_changed', (chain: ChainItem) => {
    // Handle the new chain.
    // Correctly handling chain changes can be complicated.
    // We recommend reloading the page
    // unless you have good reason not to.
    window.location.reload();
});

disconnect

DApp is disconnected from the Network. For example, lost connection between wallet and remote service.

dioxide.on('disconnect', handler: (error: ProviderRpcError) => void);

lock_status_changed

The status of Lock screen has changed. For example, the wallet locks the screen.

dioxide.on("lock\_status\_changed", (locked: boolean) => {});

Errors

The error messages returned by an RPC request:

interface ProviderRpcError extends Error {
    message: string;
    code: number;
    data?: unknown;
}

for example:

dioxide.request({
    method: "request\_connect\_address",
    params: {
        logo: "https://scan.dioxide.network/img/logo.png",
    },
})
.then((accounts: string\[\]) => {
    return accounts
})
.catch (ex: ProviderRpcError => {
    console.error(ex.code, ex.message, ex.data)
})
