Arbitrum One
StellarKey comparison
Choose Arbitrum One for Ethereum-style apps that run on a separate Ethereum-connected network. Choose Stellar for payments between currencies and issued assets. Arbitrum One uses the Ethereum rollup model; Stellar uses the Layer 1 model. Execution, validation, data publication, and settlement therefore are not interchangeable fields.
This page compares Arbitrum One with Stellar. 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 Arbitrum One and Stellar designed for?
Arbitrum One
Arbitrum One is for Ethereum-compatible applications that want to move execution off mainnet without moving final settlement away from Ethereum.
The problem. Running every application transaction directly on Ethereum competes for limited mainnet blockspace and carries its associated cost.
How Arbitrum One responds. Nitro sequences and executes transactions in the rollup, then batches transaction data and state assertions to Ethereum. Its dispute system lets Ethereum arbitrate a challenged assertion.
What remains dependent. Final settlement, data-posting costs, and the withdrawal path still depend on Ethereum rather than on an independent base layer.
Stellar
Stellar is a payment and asset-issuance network for transferring value across currencies and accounts.
How do Arbitrum One and Stellar work?
Arbitrum One
Arbitrum One is an Ethereum-connected Layer 2 network. It runs Nitro, the software that processes its transactions away from Ethereum.
Arbitrum One is an optimistic rollup: it groups transactions, runs them away from Ethereum, and posts compressed data plus a result claim to Ethereum. A validator can challenge a bad claim, so Ethereum remains the final arbiter.
Stellar
Stellar is a decentralized blockchain for payments and digital assets. Its validator computers use the Stellar Consensus Protocol (SCP): each selects trusted peers, then agrees with them on valid transactions and the next shared-ledger update. Unlike Ethereum and BNB Chain, Stellar does not use the Ethereum Virtual Machine (EVM); the network is built for payments between accounts, asset issuance, and path payments where the sender and recipient use different assets.
Arbitrum One uses the Ethereum rollup model; Stellar uses the Layer 1 model. Execution, validation, data publication, and settlement therefore are not interchangeable fields.
Arbitrum One and Stellar smart-contract and execution support
Arbitrum One
Arbitrum One runs Ethereum-style apps, so an app written for Ethereum will probably work there too.
Trade-off: it resembles Ethereum and Optimism for app compatibility, but deposits, withdrawals, and final settlement still depend on Ethereum.
Stellar
Stellar's Soroban system lets people create apps with rules that run alongside Stellar payments and issued assets.
Trade-off: it is similar to Solana and Aptos in offering a non-EVM app environment, but Ethereum Solidity contracts and EVM tools do not run unchanged on Stellar.
How does Arbitrum One compare with Stellar?
These stable design fields keep the comparison like-for-like. They are not a live performance or market scorecard.
| Criterion | Arbitrum One | Stellar |
|---|---|---|
| Designed for | Ethereum-settled EVM execution | cross-currency payments and assets |
| Network model | Ethereum rollup | Layer 1 |
| Token roles | Arbitrum One uses ETH as its native gas token. ARB is a separate governance token, not the token that pays everyday network fees. | XLM is Stellar's native asset. It pays anti-spam fees and supplies the reserve needed for accounts and ledger entries. |
| Execution | EVM-compatible | non-EVM smart-contract |
| Validation | Arbitrum One executes transactions in Nitro, posts data and result claims to Ethereum, and allows incorrect claims to be challenged before final settlement. | Stellar validators choose trusted quorum slices and accept a ledger update when the overlapping quorum requirements of the network are satisfied. |
| Application scope | Arbitrum One runs Ethereum-style apps, so an app written for Ethereum will probably work there too. | Stellar's Soroban system lets people create apps with rules that run alongside Stellar payments and issued assets. |
What are the trade-offs between Arbitrum One and Stellar?
Arbitrum One
Arbitrum One keeps Ethereum-style apps and settlement while moving everyday app activity to a separate rollup.
- Transaction experience: Swaps, lending actions, and token transfers run on Arbitrum One instead of Ethereum mainnet, but their cost still reflects the rollup's connection to Ethereum data.
- Compatibility: Solidity, Ethereum wallets, and common EVM tools carry over, making Arbitrum One closer to Ethereum and Optimism than to non-EVM chains.
- Security and control: Ethereum settles the rollup, while sequencing and the withdrawal path add their own operational assumptions.
Stellar
Stellar prioritizes payments and issued assets over EVM compatibility; its validator trust configuration is central to how the network reaches agreement.
- Payments and efficiency: Path payments can let a sender use one asset while the recipient receives another, but the route still depends on available exchange offers or liquidity pools.
- Security and centralization: Each validator chooses the peers it trusts. The published quorum configuration shows whether those trust choices are diverse enough to keep the network resilient.
- Compatibility: Soroban uses Rust rather than Solidity, so Stellar apps can work with Stellar payments and assets but Ethereum contracts and EVM tools require adaptation.
What should you check before choosing Arbitrum One or Stellar?
Current conditions can matter as much as the underlying design. Check these before making a decision:
- Arbitrum One: the total fee for the app action, how long moving funds back to Ethereum takes, who orders transactions first, and the Ethereum cost included in the price.
- Stellar: which validator groups trust each other and whether the payment route has enough available exchange offers for the assets being sent.
Arbitrum One vs Stellar: common questions
Do Arbitrum One and Stellar serve the same purpose?
Arbitrum One is designed for Ethereum-settled EVM execution; Stellar is designed for cross-currency payments and assets. They overlap only where a reader's required payment, asset, or application exists on both networks.
Is Arbitrum One or Stellar 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 Arbitrum One or Stellar the better investment?
Arbitrum One uses ETH as its native gas token. ARB is a separate governance token, not the token that pays everyday network fees. XLM is Stellar's native asset. It pays anti-spam fees and supplies the reserve needed for accounts and ledger entries. This page does not contain current comparable price, liquidity, supply, exchange-access, governance-concentration, or regulatory evidence, so it cannot identify a better investment.
