Read a C0 balance

1

Create a wagmi config

import { createConfig, http } from "@wagmi/core";
import { mainnet } from "@wagmi/core/chains";

const config = createConfig({
  chains: [mainnet],
  transports: { [mainnet.id]: http() },
});
2

Call readC0BalanceOf

import { readC0BalanceOf, addresses } from "@camino-treasury/sdk";

const balance = await readC0BalanceOf(config, {
  address: addresses[mainnet.id].c0,
  args: ["0xYourAddressHere"],
});

console.log(balance); // bigint, scaled to 6 decimals
3

Format the value

import { formatUnits } from "viem";

console.log(formatUnits(balance, 6)); // "123.456789"
C0 has 6 decimals. The raw bigint returned by readC0BalanceOf is the on-chain value scaled by 10^6.

What’s exported

@camino-treasury/sdk exposes the same surface from four entry points:
Import pathWhat you get
@camino-treasury/sdkEverything — flat re-export of data, actions, and claim (default for most users).
@camino-treasury/sdk/dataPer-chain addresses, the C0Addresses type, and raw ABIs.
@camino-treasury/sdk/actionsTyped read* / write* / simulate* / watch*Event helpers.
@camino-treasury/sdk/claimgetPeriods, claim, and the Period type for the yield-claim flow.
Use the subpaths when you want narrower imports or to make data-vs-action usage explicit. The flat root works for everything. See c0-token, swap-facility, and swap-adapter for the per-contract surface.
