Optimism
SolanaKey comparison
Choose Optimism for Ethereum-style apps on an OP Stack network. Choose Solana for fast-moving apps outside Ethereum's toolset. Optimism uses the Ethereum rollup model; Solana uses the Layer 1 model. Execution, validation, data publication, and settlement therefore are not interchangeable fields.
This page compares Optimism with Solana. It looks at what each chain is for, how it works, what its token does, and which apps it can run. Live fees, speed, trading depth, safety, and future value can change, so this page does not rank them.
What are Optimism and Solana designed for?
Optimism
Optimism is for Ethereum-compatible applications that need a separate execution layer while retaining Ethereum settlement.
The problem. Putting every application transaction on Ethereum mainnet makes applications compete for the same constrained blockspace and its related cost.
How Optimism responds. The OP Stack separates execution, consensus, data availability, and settlement. Optimism processes activity at Layer 2 while Ethereum finalizes the resulting transactions.
What remains dependent. Sequencing, data publication, proof handling, and withdrawal timing remain part of the comparison because the chain settles on Ethereum.
Solana
Solana is a high-throughput Layer 1 for applications, with SOL used for fees and staking.
How do Optimism and Solana work?
Optimism
It uses an EVM-compatible optimistic-rollup model whose settlement and data publication depend on Ethereum.
Solana
Its non-EVM runtime combines proof-of-stake validation with proof-of-history-based time ordering.
Optimism uses the Ethereum rollup model; Solana uses the Layer 1 model. Execution, validation, data publication, and settlement therefore are not interchangeable fields.
Optimism and Solana smart-contract and execution support
Optimism
Optimism runs Ethereum-style apps away from Ethereum mainnet, then sends their results back to Ethereum for final settlement.
Trade-off: it is close to Ethereum and Arbitrum for app compatibility, but bridges, withdrawals, and the rollup's connection to Ethereum still matter.

Solana
Solana runs on-chain programs, usually written in Rust, with program code kept separate from the accounts that hold changing data.
Trade-off: it is similar to Aptos as a non-EVM app platform, but Ethereum contracts and EVM tools need to be rewritten for Solana's account model.

How does Optimism compare with Solana?
These stable design fields keep the comparison like-for-like. They are not a live performance or market scorecard.
| Criterion | Optimism | Solana |
|---|---|---|
| Designed for | EVM execution and OP Stack rollups | high-throughput non-EVM apps |
| Network model | Ethereum rollup | Layer 1 |
| Token roles | Optimism uses ETH for transaction fees. OP is its governance token, so it is not the token a user needs to pay ordinary network fees. | SOL is Solana's native token. It pays fees, secures the network through staking, and funds account storage requirements. |
| Execution | EVM-compatible | non-EVM smart-contract |
| Validation | OP Mainnet executes transactions on the rollup, publishes compressed batches and state commitments to Ethereum, and reaches finality through Ethereum. | Proof-of-stake validators vote on blocks while proof of history supplies the ordered timing information used by the protocol. |
| Application scope | Optimism runs Ethereum-style apps away from Ethereum mainnet, then sends their results back to Ethereum for final settlement. | Solana runs on-chain programs, usually written in Rust, with program code kept separate from the accounts that hold changing data. |
What are the trade-offs between Optimism and Solana?
Optimism
Optimism gives Ethereum-style apps a separate execution layer while keeping final settlement on Ethereum.
- Transaction experience: Everyday app actions run on the rollup rather than Ethereum mainnet, but data publication, sequencing, and withdrawal design still shape the user experience.
- Compatibility: Solidity, Ethereum wallets, and common EVM tools make Optimism close to Ethereum and Arbitrum for application use.
- Security and control: Ethereum settlement is the foundation, while the selected OP Stack chain and its sequencer model remain material differences between deployments.
Solana
Solana is built for application activity and token accounts with a runtime that differs sharply from Ethereum's EVM.
- Efficiency: Its program and account model is designed for frequent app actions, but a published maximum transaction figure is not the same as an application's observed throughput.
- Compatibility: Rust and Anchor tooling differ from Solidity and the EVM, so Ethereum contracts and wallet integrations need dedicated Solana work.
- Security and access: Proof-of-stake validators secure the network; compare validator operation, current prioritization costs, and the exact app workflow rather than relying on a headline speed claim.
What should you check before choosing Optimism or Solana?
Current conditions can matter as much as the underlying design. Check these before making a decision:
- Optimism: which OP Stack network the app uses, who orders its transactions first, and the total fee including Ethereum data costs.
- Solana: how many transactions the actual app processes, the wallet fee shown before sending, and any extra payment for faster processing.
Optimism vs Solana: common questions
Do Optimism and Solana serve the same purpose?
Optimism is designed for EVM execution and OP Stack rollups; Solana is designed for high-throughput non-EVM apps. They overlap only where a reader's required payment, asset, or application exists on both networks.
Is Optimism or Solana faster and cheaper?
The stable design fields on this page cannot establish a current winner. Compare the same wallet action, asset route, confirmation target, and observation window on both networks, then separate the network fee from bridge, swap, spread, or liquidity costs.
Is Optimism or Solana the better investment?
Optimism uses ETH for transaction fees. OP is its governance token, so it is not the token a user needs to pay ordinary network fees. SOL is Solana's native token. It pays fees, secures the network through staking, and funds account storage requirements. This page does not contain current comparable price, liquidity, supply, exchange-access, governance-concentration, or regulatory evidence, so it cannot identify a better investment.
