Comisiones de Robinhood Chain explicadas: lo que deben saber los usuarios de criptomonedas sobre la nueva blockchain de Robinhood

New Layer 2 networks promise transactions for a pittance. In practice, however, costs often turn out to be higher than expected: bridges, slippage and hidden platform fees. Robinhood Chain is an Ethereum Layer 2 solution from the broker Robinhood, launched on 1 July 2026. Gas fees are paid in ETH, and there is a 90-day subsidy for Robinhood Wallet users. Let’s break down how the fees work, what lies behind the ‘fractional gas fees’, and what to check before using the network.

What is Robinhood Chain

What is Robinhood Chain? It is an Ethereum Layer-2 network based on the Arbitrum Orbit stack, launched on the mainnet on 1 July 2026. Its Chain ID is 4663. The network is fully EVM-compatible: Solidity smart contracts can be deployed without modification, and users can connect via MetaMask, Rabby or any EVM wallet.
 

The creator is Robinhood Markets (ticker: HOOD), a US brokerage firm with millions of users. The network’s focus is on tokenised assets: Stock Tokens for shares and ETFs, 24/7 trading, and DeFi protocols. Uniswap, 1inch and Lighter have been operating on-chain from day one.
 

The Robinhood Chain blockchain does not have a native token. Gas is paid in ETH – this is the network’s sole gas token. Any tokens with names such as ‘Robinhood Chain coin’ are unofficial meme coins with no connection to the platform.

How fees work: gas in ETH

Robinhood Chain fees consist of two components: the L2 execution fee – the cost of executing a transaction on Robinhood Chain – and the L1 data fee – the cost of publishing data on Ethereum.
 

But there is a key difference from other Arbitrum Orbit chains. The L1 data fee on the Robinhood Chain is set to zero. According to Bitquery data verified on September 4, 2026, gasUsedForL1: 0x0 in all transactions, there is no separate l1Fee field. In practice, the user pays only the L2 execution fee. Base fee works according to the EIP-1559 model: it grows when overloaded, falls to the floor when idle. The initial minimum level (floor) is set to 0.02 gwei, which is the starting value from which the base fee rises as the load increases.
 

In practice, the user pays only the L2 execution fee. The base fee operates according to the EIP-1559 model: it rises during periods of high congestion and falls to the floor during periods of low activity. The floor is fixed at 0.02 gwei. The base fee goes to the operator (Robinhood) rather than being burned – unlike on Ethereum.
 

Robinhood retains ~90% of net gas revenue after deducting the costs of publishing data on Ethereum and a 10% share for the Arbitrum ecosystem (8% goes to the Arbitrum DAO treasury, 2% to the developer fund). On 3 September 2026, Robinhood Chain paid Ethereum approximately $400 for publishing data for the entire day – whilst collecting $4.5 million in fees.

How much does a real transaction cost?

Measurements by 10 Coin Lab (5 September 2026, ETH approximately $2,477):

The base fee rose 25-fold in 11 days: from 0.020 to 0.511 gwei (according to Bitquery). The average transaction fee reached $0.38–$0.40 by early September. Peak spikes reached 7.13 gwei – 18 times higher than the median. Daily network fees: $3.75 million on 1 September, $6 million on 4 September – a record, surpassing Ethereum’s mainnet and Base combined.

Gas subsidy: who pays, and who doesn’t

The 90-day subsidy is valid until 29 September 2026. It covers only swaps within the Robinhood Wallet – the exchange of cryptocurrencies or Stock Tokens worth more than $0.50 (the threshold was originally $5, but was later reduced). Some ‘approve’ transactions are also covered by the subsidy.
 

What the subsidy does not cover:
 

• Transfers between wallets.
• Bridges.
• Activity from third-party wallets: MetaMask, Rabby, Bitget.
• Activity via the Robinhood Wallet’s built-in dapp browser.
   

Third-party wallets pay the full gas fee from day one. During the subsidy period, daily network fees amounted to ~$4,000 – Wallet users paid nothing; Robinhood absorbed the costs. After 29 September, a test will begin to see whether the volume is maintained once users start paying themselves. Analysts describe the current activity as a ‘borrowed moment’.

FCFS sequencer: why the priority fee doesn’t help

Robinhood Chain crypto uses a First-Come, First-Served (FCFS) sequencer. Transactions are ordered strictly by time of arrival, not by fee. There is no public mempool – transactions go straight into the sequencer’s private queue and only become visible once they are in a block.
 

Increasing the priority fee does not move a transaction further up the queue. Gas determines whether you will be included in a block, not where you will end up within it. Traditional MEV via fee-bidding is absent: there is no priority gas auction, and no front-running via the mempool.
 

However: the sequencer is centralised – a single operator, Robinhood. Blocks are produced approximately every 100 ms. Theoretical risks: network downtime in the event of a sequencer failure; transaction censorship based on sanctions lists. Partial censorship resistance is only achievable via a fork-off to Ethereum.

Hidden costs: bridges, slippage, withdrawals

Gas may cost $0.02, but the actual costs are higher. Full formula: funding + bridge + gas + trading commission + slippage + price impact + withdrawal + return bridge.

Bridges. Canonical Ethereum → Robinhood Chain bridge: 10 minutes, Ethereum gas fee ($0.03 at 1 gwei). Aggregator bridges (Relay, Across, Jumper) take a percentage of the amount – from 0.85%.
 

Withdrawal. Standard withdrawal to Ethereum – 7 days (challenge period) + L1 gas for the claim transaction. Fast withdrawal via intents bridges – takes seconds, but at a percentage of the amount.
 

Slippage. Gas costs $0.05, but slippage on memecoins with thin liquidity is 2–4 per cent. Execution costs more than the gas.
 

Approve + swap. The first transaction with a new token involves two operations, not one. The gas cost is small, but it’s double.
 

Wallet fee. Robinhood Wallet charges 0.80% for same-chain swaps and 0.73% for cross-chain swaps – on top of network gas fees.
 

ETH minimum. You need ETH specifically on the Robinhood Chain (Chain ID 4663). ETH on Ethereum or another L2 won’t work – you’ll need to bridge it first.

Robinhood Chain vs other networks

On 5 September, the gas cost per unit on Robinhood Chain was higher than on Ethereum (0.405 vs 0.055 gwei), 20 times higher than on Arbitrum One and 70 times higher than on Base. However, Base and Arbitrum add an L1 data fee on top of the L2 gas, whereas Robinhood Chain does not. The absolute cost of a transaction is still in cents.

Risks: what to check before using

Sequencer centralisation. A single operator. A failure brings the network to a standstill. In the first few weeks after launch, the network experienced congestion and a high proportion of rejected transactions, particularly during periods of peak activity surrounding launches on Pons.
 

Stock Tokens are not shares. They are debt instruments issued by Robinhood Assets (Jersey) Ltd. There are no ownership rights. They are not available in the US. Robinhood has announced plans to add 1:1 redemption and voting rights, but has not specified a timeline.
 

Concentration of activity. Bitquery: the gas price rose 25-fold over 11 days; a significant proportion of the load comes from a small number of highly active wallets.
 

7-day withdrawal. The canonical bridge locks funds for a week.

Dexsport: a blockchain without intermediaries

Dexsport is a decentralised betting platform with no KYC, supporting 94 cryptocurrencies across 28 networks. Fast payouts via smart contracts, a shared liquidity pool. The philosophy is similar to Robinhood Chain: to remove barriers between the user and the product. Robinhood reduces fees for on-chain activity; Dexsport eliminates intermediaries in betting. Both use blockchain to cut out unnecessary links.

Conclusion

Robinhood Chain is not ‘just another cheap L2’. Fees in ETH with a zero-cost L1 component and an FCFS sequencer represent a unique model. However, the centralised sequencer, volume dependence on meme coins, a 7-day withdrawal period and the concentration of activity in a few wallets are real limitations. 29 September – a test of resilience. Projects such as Dexsport demonstrate that blockchain transparency and speed are transforming not only exchanges but also related industries – betting, gaming and DeFi.
