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#

FieldTypeDescription
result.ss58formatnumberSS58 network identifier (77 for Manta Atlantic).
result.tokenSymbolstring or arraySymbol(s) of native tokens (MANTA).
result.tokenDecimalsnumber or arrayDecimal precision (18).

Response Snapshot#

{
  "jsonrpc": "2.0",
  "result": {
    "ss58format": 77,
    "tokenDecimals": 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.
