Arbitrum Rollup can scale any Ethereum contract. It's the ideal scaling solution for many DeFi apps and any application which is open to public participation. Arbitrum Rollup contracts enjoy the fully trustless security of the underlying blockchain, all while simultaneously increasing the dapp's capacity and greatly reducing costs.
| Security | Privacy | Public Participation | Validation | Cost | Finality | Censorship Resistant | |
|---|---|---|---|---|---|---|---|
| Rollup | Trustless | | Permissionless | Low | Same as L1 | | |
| Sidechains | AnyTrust | | | Permissioned | Lowest | Instant | |
| Channels | Trustless | | All participants validate | Lowest | Instant | | |
| L1 Ethereum | Trustless | | Permissionless | High | Minutes | |
Arbitrum supercharges dapps by breaking out beyond the underlying blockchain's computational and storage limits
Arbitrum runs at a fraction of the cost of native L1 contracts. Arbitrum has low fixed on-chain costs for storage and computation, no matter how many resources you use.
No new coding paradigms or programming languages to learn here. The Arbitrum toolchain automatically converts your existing Solidity contracts to Arbitrum contracts. Arbitrum works with web3,ethers, and go-ethereum so you don’t have to rewrite your front-end either.
Seamlessly and securely transfer tokens between Arbitrum and the L1 blockchain. That's right -- your existing tokens are fully supported by Arbitrum. Right out of the box.
Unlike other projects that don't give the same security as the underlying blockchain, Arbitrum guarantees correctness and is as fully trustless and secure as the blockchain it's built on.
If you're looking for private smart contracts, you've come to the right place. Arbitrum channels and sidechains offer strong privacy modes guaranteeing that nobody other than the participants of an Arbitrum channel or the validators of a sidechain can see the application's code or its internal state. Only public actions such as payments are visible to the world.
