Pro tip: When withdrawing funds from an exchange to your Optimism account, be sure to choose the Optimism network to avoid the possibility of the funds being directed to a different account. You can receive ETH, OP and ERC20 tokens on your account, using a Ledger device to verify and approve transactions. That’s it, your Optimism account is added to your portfolio. Open the Ethereum (ETH) app on your device.Connect your device to the Ledger Live app and unlock it.Choose Optimism (ETH) from the drop-down list.In the left sidebar menu, go to Accounts.Now let’s add your Optimism account to Ledger Live. The Ethereum (ETH) app is installed on your Ledger device. In My Ledger, head over to App catalog and search for Ethereum (ETH). You can do that by clicking both buttons on your device simultaneously. Confirm that you allow My Ledger to access your device.In the Ledger Live app, navigate to My Ledger.Connect your Ledger device and unlock it.Install the Ethereum (ETH) app on your Ledger device Update the firmware on your Ledger Nano S / Nano S Plus / Nano X.Download and install the latest version of Ledger Live.Learn more about the Optimism project here. It is a virtual sandbox with a set of network consensus rules present in every Ethereum node in charge of executing smart contracts.You can manage, send, and receive ETH, OP and 100+ ERC20 tokens on the Optimism blockchain. That's because Optimism uses EVM (Ethereum Virtual Machine). However, if Ethereum receives a major consensus overhaul, re-executing L1 transactions would lead to divergent final states. Optimism's Ethereum Dependencyīoth Arbitrum and Optimism are optimistic rollup protocols because they rely on the majority of Ethereum validators to process transactions honestly. Likewise, because L2 transactions are not entirely executed on L1, its gas block limit is rendered irrelevant. In turn, this translates to higher network performance. By using multi-round FP, Arbitrum focuses on a singular point of transaction disagreement. In contrast, Arbitrum uses a fine-combing approach to FP verification. However, this exerts greater costs because on-chain L1 execution costs more gas, and the L2 fee is itself limited by the L1 gas block. This way, the FP verification is instant. Optimism's single-round fraud-proof (FP) relies on L1 to execute the entire L2 transaction. The most important difference is that Optimism rollup uses single-round fraud proofs, while Arbitrum uses multi-round fraud proofs. As often happens in the software field, Arbitrum team then tweaked its source code, which led to two different layer 2 scalability solutions. To begin with, it is important to understand that the Optimism team first created Rollups. What Are the Differences Between Arbitrum and Optimism? Cross-chain bridges: Allowing tokens to move between layer 1 and layer 2.Īlthough both Optimistic Rollups (ORs) and Arbitrum drastically lower ETH gas fees, there are key differences in how they verify proofs and how they handle future compatibility issues.Once again, this makes for a low-latency, high-throughput network. Instant finality: The transactions are finalized the moment the block is created, instead of undergoing a series of confirmations. ![]() In turn, this saves the computational resources of the network. ![]()
