system_properties

Description

Returns static chain properties such as the SS58 address prefix, token symbol(s), and decimal precision. Clients and wallets use this information to format addresses and balances correctly for BNC and other registered assets.

Parameters

This method does not take parameters.

Returns

Field	Type	Description
ss58Format	number	SS58 prefix for address encoding
tokenSymbol	array	List of native token symbols
tokenDecimals	array	Decimal precision for each token symbol
currencyTypes	object	(Optional) Mapping of additional asset identifiers

Request Example

{
  "jsonrpc": "2.0",
  "method": "system_properties",
  "params": [],
  "id": 1
}

Response Example

{
  "jsonrpc": "2.0",
  "result": {
    "ss58Format": 6,
    "tokenSymbol": ["BNC"],
    "tokenDecimals": [12]
  },
  "id": 1
}

Code Examples

JavaScript (polkadot.js)

const provider = new WsProvider('wss://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY');
const api = await ApiPromise.create({ provider });

const properties = api.registry.getChainProperties();
console.log(properties?.toHuman());

Python (py-substrate-interface)

from substrateinterface import SubstrateInterface

substrate = SubstrateInterface(
    url="wss://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY"
)

props = substrate.properties
print("SS58 prefix:", props.ss58_format)
print("Symbols:", props.token_symbol)
print("Decimals:", props.token_decimals)

Rust (subxt)

use subxt::{config::substrate::SubstrateConfig, OnlineClient};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let api = OnlineClient::<SubstrateConfig>::from_url("wss://api-bifrost-polkadot.n.dwellir.com/YOUR_API_KEY").await?;
    let props = api.rpc().system_properties().await?;
    println!("Properties: {:?}", props);
    Ok(())
}

Notes

• Bifrost uses SS58 prefix 6. Attempting to decode accounts with prefix 0 (Polkadot) or 2 (Kusama) will fail.
• Additional derivatives may expose extra symbols through runtime metadata; consult the Asset Registry pallet when listing vToken symbols.
