The Robinhood Chain network

Robinhood Chain is a blockchain for stock tokens, trading apps and lending markets. It processes transactions on its own network, then publishes transaction data to Ethereum. That arrangement is called a Layer 2.

Robinhood’s developer documentation identifies the software as Arbitrum Dedicated Blockchains, also known as Arbitrum Orbit. Users pay transaction fees in ETH. Data needed to reconstruct the chain is published on Ethereum as blobs or calldata.

Blocks arrive about ten times a second

A 5,000-block sample on 5 October 2026 measured an average interval of 0.101 seconds. The network stood at block 80,980,158, with a gas price of 0.02049 gwei at 17:59 UTC. These are dated readings; fees change with demand.

Robinhood orders transactions by arrival at its sequencer. Higher priority fees cannot move a transaction ahead in that queue. Developers can sponsor gas, batch calls and use session keys through ERC-4337 account abstraction.

Ethereum settlement takes longer

Robinhood’s finality guide separates the fast sequencer receipt from the later stages of settlement:

Two authorised actors can challenge the state

On 3 October 2026, L2Beat recorded two whitelisted challengers and a 6-day 8-hour challenge period. It also recorded immediate upgrade powers and an authorised transaction filter that can make specified transactions fail, including transactions forced through Ethereum.

L2Beat’s stage panel places the node-software availability requirement under review. The practical trust assumptions sit with the challengers, the upgrade controllers and the transaction filter. Ethereum publishes the data used for proofs.

Choose a bridge by its withdrawal process

Robinhood’s bridge guide describes canonical Ethereum deposits as taking about ten minutes and withdrawals as taking roughly seven days, followed by an Ethereum claim transaction. That withdrawal estimate includes a challenge period.

The same guide lists Relay and Across for transfers fulfilled by liquidity providers, LayerZero/Stargate and Chainlink CCIP for token transfers and messages, and LiFi/0x for swap-and-bridge routing. Each route has its own contracts, fees and settlement process.
