DEXs & DeFi
Fast reads, reliable writes, and simulation for swap and liquidity flows.
What is HOODSTACK?
Robinhood Chain is a fully EVM Layer 2 — your Solidity, your tooling, your habits all carry over. What doesn't carry over is production infrastructure. HOODSTACK is that layer: managed nodes, ERC-4337 gas sponsorship, a transaction engine, and indexed data, built for one chain and tuned for it.
Read the overview →ENDPOINTS
Endpoints that hold up under load.
The public RPC is fine for a demo and rate-limited everywhere else. HOODSTACK gives you dedicated HTTPS and WebSocket endpoints on mainnet and testnet, with archive access when you need history — no nodes to babysit, no 3am pages.
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.
EXECUTION
Fewer failed transactions, by design.
Simulate before you send so reverts never reach the chain. Batch several actions into one operation. Use session keys for flows that shouldn't ask for a signature every step. Nonce handling, retries, and replacement are ours to worry about.
DATA
Skip the indexer you were about to build.
Blocks, logs, token metadata, transfers, and balances through a REST and WebSocket API. Subscribe to the events you care about and get a webhook instead of writing another polling loop.
OPERATE
See every request you send.
Keys, quotas, per-method usage, error breakdowns, and alerts in one console. Know what broke and when, before your users tell you.
QUICKSTART
Change the endpoint. That's the migration.
Robinhood Chain is fully EVM-compatible, so Hardhat, Foundry, ethers.js, viem, and Wagmi all work unchanged. Point them at HOODSTACK and keep writing the app.
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()); // 4663Same RPC, same tooling — only the endpoint changes.
Full quickstart →COST
Cheaper in the places that actually cost you.
Nobody discounts a chain's gas, and we won't pretend to. What we cut is everything around it — the gas your users can't pay, the transactions that revert, the operations you sent one at a time.
Sponsored gas
Cover fees for your users so onboarding doesn't stall at "buy ETH first".
Batched operations
Bundle several actions into one user operation instead of paying overhead on each.
Simulate first
Catch reverts off-chain. A transaction that never sends never burns gas.
Spend policies
Set caps per user, per action, per day, so sponsorship stays predictable.
Gas on Robinhood Chain is paid in ETH. Sponsorship moves who pays it, not what the network charges.
Numbers we'll publish once we can prove them.
