HOODSTACK

GASLESS

Gas Sponsorship

ERC-4337 bundler and paymaster so users can transact before they hold ETH.

GASLESS

Your users shouldn't need ETH to start.

Robinhood Chain ships with first-class ERC-4337 support, and HOODSTACK gives you the bundler and paymaster to use it. Sponsor gas for specific actions, cap spend per user or per day, and let people transact before they have ever bridged a cent.

The problem

New users stall at the first on-chain action when they have no ETH for gas.

How HOODSTACK helps

Sponsor specific actions, set spend caps per user or per day, and keep onboarding moving without pretending the network fee itself is free.

Snippet

client.ts
import { createPublicClient, http, defineChain } from "viem";

const robinhood = defineChain({
  id: 4663,
  name: "Robinhood Chain",
  nativeCurrency: { name: "Ether", symbol: "ETH", decimals: 18 },
  rpcUrls: {
    default: { http: ["https://rpc.mainnet.chain.robinhood.com"] },
  },
  blockExplorers: {
    default: { name: "Blockscout", url: "https://robinhoodchain.blockscout.com" },
  },
});

const client = createPublicClient({
  chain: robinhood,
  transport: http(),
});

console.log(await client.getBlockNumber());
console.log(await client.getChainId()); // 4663
