Query the chain

Web (CosmJS)

import { StargateClient } from '@cosmjs/stargate';

const RPC = 'https://rpc.testnet.safrochain.com:443';
const DENOM = 'usaf';

const client = await StargateClient.connect(RPC);
console.log(await client.getHeight(), await client.getChainId());

const address = 'addr_safro1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
console.log(await client.getBalance(address, DENOM));

const validators = await client.getValidators();
console.log(validators.slice(0, 3).map((v) => v.description?.moniker));

React Native

Same StargateClient APIs. Prefer polling REST on battery-sensitive screens instead of persistent WebSocket.

const bal = await client.getBalance(address, DENOM);

Flutter (CosmJS)

import { StargateClient } from '@cosmjs/stargate';

const client = await StargateClient.connect('https://rpc.testnet.safrochain.com:443');
const bal = await client.getBalance(address, 'usaf');
console.log(bal);
