Arbitrum Bridge Tutorial (2024)

FAQs

How long does it take to bridge to Arbitrum? ›

After you submit the transaction through your web3 wallet you can expect your funds to arrive on the destination chain within roughly 15-30 minutes (depending on the chain congestion). Also make sure your wallet is set to the destination chain so you can see your funds when they arrive.

Risks of using the Arbitrum bridge

The use of a centralized sequencer in the initial stages can influence transaction ordering, and if there are no honest validators, then a malicious actor can steal funds by posting invalid blocks and state commitments.

Defiway bridge supports the cross-chain bridging of ETH between chains for the lowest cost, at the fastest speeds available. The Arbitrum to Ethereum fee varies depending on the network load and market conditions.

Why do I have to wait 8 days? This is how all optimistic rollups work. Optimistic rollups use something called fraud proofs in order to keep participants in the network honest. There is a "challenge period" for these proofs.

High degree of centralization: Arbitrum's security depends on its operators, which may lead to risks of centralization.

Arbitrum can reach 40,000 TPS, way faster than its main competitor, Optimism, which can only process 20,000 transactions per second. However, Polygon is the fastest L2, as it can handle 65,000 transactions per second. But all the same, charts and data point to the Arbitrum platform as the second L2 in terms of speed.

Yes, you can send ETH directly to Arbitrum using a bridge. You'll need to connect your Ethereum wallet to the bridge, select ETH as the token to transfer and complete the bridging process.

Transactions are executed off-chain, and assets are held in a smart contract on-chain. A primary benefit of Arbitrum is its super-fast transaction speeds (TPS). Ethereum averages around 30 TPS, compared to a staggering 40,000 TPS for Arbitrum transactions. Faster transactions equal lower fees.

Arbitrum Markets

The current price of Arbitrum is $0.67 per ARB. With a circulating supply of 3,339,278,542 ARB, it means that Arbitrum has a total market cap of $2,253,923,510.26. The amount of Arbitrum traded has risen by $9,557,425.98 in the last 24 hours, which is a 6.55% increase.

Is arbitrum faster than Polygon? ›

ARB vs MATIC: Transaction Speed

Arbitrum and Polygon both increase transaction speed from a few transactions per second to several thousand. However, while Arbitrum can take speeds to about 40,000 transactions per second (TPS), Polygon can process nearly 200% of Arbitrum's speed, at nearly 65,000 TPS.

After getting their receipt, The sequencer posts their transaction in a batch (usually within a few minutes, though the sequencer will wait a bit longer if the L1 is congested). Then, A validator includes their transaction in an RBlock (usually within the hour).

For example if a user is bridging from Ethereum to Polygon, the first transaction on Ethereum typically takes 10-20min. The transaction on Polygon happens much faster afterwards, typically within a few minutes.

The only delay that's felt by a user is in "withdrawing" — moving their funds from Arbitrum back to Ethereum; if users are withdrawing directly from Arbitrum to Ethereum, they must typically wait 1 week before receiving their funds on L1.
