ToolPack
An open-source, privacy-first toolkit for Robinhood Chain that runs entirely in your browser.
ToolPack is a collection of on-chain utilities for Robinhood Chain. Send tokens to a whole list of wallets, deploy an ERC-20, audit your approvals, decode a transaction, generate a merkle airdrop, and more, all from a single site.
Everything runs in your browser: you connect your own wallet, the app talks directly to the chain's RPC, and you pay and sign every transaction yourself. There is no account to create and no server in between.
Principles
These four properties hold for every tool on the site.
- Static frontend, no database. The app never stores your addresses, balances, keys, or lists on a server, because there is no server-side logic to store them on.
- Browser talks only to required public services. Reads go to the Robinhood Chain RPC and writes go to your wallet. Some tools also use Blockscout or openchain.xyz; the optional GitHub star count uses api.github.com; and Reown/WalletConnect handles wallet discovery and relay transport when wallet integration is enabled. See Privacy by design for the details.
- You pay and you sign. The app never holds funds and never has custody. Every transaction is built in your browser and sent to your own wallet for approval. You pay the gas; the app adds nothing.
- Open source, MIT licensed. The entire codebase is public. You can read it, audit it, fork it, or self-host it.
Tools

Read
| Tool | What it does |
|---|---|
| Batch Balance Checker | Check native and token balances for hundreds of addresses. |
| Transaction Decoder | Turn a tx hash or raw calldata into a human-readable action. |
| Network Tracker | Live gas, blocks, and RPC health for Robinhood Chain. |
Offline
The computations in these tools run locally. Wallet-enabled app infrastructure can still make wallet-discovery or relay requests, and the signing half of Sign & Verify uses your wallet.
| Tool | What it does |
|---|---|
| Merkle Tree Generator | Build airdrop merkle roots and proofs, fully offline. |
| Sign & Verify | Sign messages and verify signatures. |
| Unit & Hex Converter | wei, gwei, ether, hex, keccak256, and checksums. |
