system_properties

Returns static chain configuration values such as token symbol, decimals, and SS58 address format. Use this to configure wallets, indexers, and explorers targeting Manta Atlantic.

Parameters

This method does not take parameters.

Returns

Field	Type	Description
result.ss58format	number	SS58 network identifier (77 for Manta Atlantic).
result.tokenSymbol	string or array	Symbol(s) of native tokens (MANTA).
result.tokenDecimals	number or array	Decimal precision (18).

Usage Examples

import { ApiPromise, WsProvider } from '@polkadot/api';

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

const props = await api.rpc.system.properties();
console.log(props.toHuman());

import json
import requests

resp = requests.post(
    "https://api-manta-atlantic-mainnet.n.dwellir.com/YOUR_API_KEY",
    headers={"Content-Type": "application/json"},
    data=json.dumps({
        "jsonrpc": "2.0",
        "method": "system_properties",
        "params": [],
        "id": 1
    }),
    timeout=10,
)
print(resp.json()["result"])

Operational Tips

• Use ss58format = 77 when encoding addresses; mismatched formats will yield different checksums.
• Update UI displays to use 18 decimals—1 MANTA = 10^18 planck.
• Some parachain runtimes return arrays for multi-token chains; handle both string and array forms defensively.
