Optimism (OP)

What is Optimism?

Here are five key points about the Optimism blockchain:

Layer 2 for Ethereum: Optimism is built on top of Ethereum, designed to improve scalability and lower costs.

Optimistic rollups: Transactions are bundled off-chain and posted to Ethereum as a single batch, reducing congestion and fees.

EVM compatible: Developers can deploy existing Ethereum smart contracts and dApps to Optimism with little to no modification.

Security anchored to Ethereum: By submitting data to Ethereum, Optimism inherits its robust security model.

Native tokens: Transactions are paid in ETH on Optimism, while the OP token is used for governance in the Optimism DAO.

Optimism on Wraith Wallet

Wraith Wallet supports Optimism with:

Buy ETH (on Optimism) and OP via debit/credit cards.

Store ETH, OP, and ERC-20 tokens securely.

Send and receive ETH, OP, and ERC-20 tokens.

Swap ETH and ERC-20 tokens directly within the wallet.

What are Optimism ERC-20 tokens?

ERC-20 tokens are issued via smart contracts on Ethereum.

Optimism supports their transfer and use through bridging from Ethereum to Optimism.

This enables access to Ethereum’s full dApp ecosystem with much lower fees.

How to get ETH on Optimism

You can acquire Optimism ETH through Wraith Wallet by:

Buying ETH (Optimism) directly in the app.

Receiving ETH at your unique Optimism address.

Swapping ERC-20 tokens for ETH (requires ETH to cover gas fees).

⚠️ Important: Send only ETH bridged to Optimism to your Optimism address.

Transaction fees on Optimism

Transactions on Optimism are paid in ETH.

Fees are typically lower than Ethereum mainnet due to rollup compression.

Costs remain stable and predictable, even during periods of high activity.

Checking your Optimism (OP) balance

Wraith Wallet connects directly to the Optimism network to display balances.

To verify on-chain, tap the three dots and select View address on OP Etherscan.

OP Etherscan is Wraith Wallet’s default Optimism block explorer.
