@mistcash/config

The config package provides shared constants, contract ABIs, token metadata, and TypeScript types used across the SDK.

Installation

pnpm add @mistcash/config

Contract Addresses

`CHAMBER_ADDR_MAINNET`

The mainnet Chamber contract address on Starknet.

import { CHAMBER_ADDR_MAINNET } from "@mistcash/config";

console.log(CHAMBER_ADDR_MAINNET);
// "0x06f8dcc500131b6be6b33f4534ec6d33df33e61083ec2b051555d52e75654444"

ABIs

`CHAMBER_ABI`

The full ABI for the Chamber smart contract, used to create typed contract instances.

import { CHAMBER_ABI } from "@mistcash/config";
import { Contract } from "starknet";

const chamber = new Contract(CHAMBER_ABI, CHAMBER_ADDR_MAINNET, provider);

`ERC20_ABI`

Standard ERC20 ABI for interacting with token contracts.

import { ERC20_ABI } from "@mistcash/config";
import { Contract } from "starknet";

const token = new Contract(ERC20_ABI, tokenAddress, provider);
const balance = await token.balance_of(address);

Supported Tokens

`tokensData`

Array of all supported tokens with their metadata.

import { tokensData } from "@mistcash/config";

for (const token of tokensData) {
  console.log(token.name, token.address, token.decimals);
}

Each token object has the following shape:

interface Token {
  name: string;      // Human-readable name (e.g., "Ether")
  symbol: string;    // Symbol (e.g., "ETH")
  address: string;   // Starknet contract address
  decimals: number;  // Token decimals (e.g., 18)
  image?: string;    // Optional icon URL
}

Available tokens:

Name	Symbol	Decimals
Ether	ETH	18
Stark	STRK	18
USD Coin	USDC	6
Tether	USDT	6
Survivor	SURVIVOR	18

`tokensMap`

Lookup tokens by contract address.

import { tokensMap } from "@mistcash/config";

const eth = tokensMap["0x049d36570d4e46f48e99674bd3fcc84644ddd6b96f7c741b1562b82f9e004dc7"];
console.log(eth.symbol); // "ETH"

`tokenNamesMap`

Lookup tokens by name.

import { tokenNamesMap } from "@mistcash/config";

const usdc = tokenNamesMap["USDC"];
console.log(usdc.address);

Types

`ChamberTypedContract`

TypeScript type for the typed Chamber contract instance. Use this for type-safe contract interactions.

import type { ChamberTypedContract } from "@mistcash/config";

function doSomething(chamber: ChamberTypedContract) {
  // Full type safety for all contract methods
  const root = await chamber.merkle_root();
}

`Token`

Interface for token metadata.

import type { Token } from "@mistcash/config";

function renderToken(token: Token) {
  return `${token.symbol}: ${token.address}`;
}
