Arbitrum vs NEAR Protocol: Layer 2 Rollup vs Sharded Layer 1
Arbitrum is an Ethereum Layer-2 optimistic rollup that scales smart contracts offchain while settling batches directly to Ethereum. NEAR Protocol is an independent Layer-1 proof-of-stake blockchain that uses dynamic sharding to run transactions in parallel.
The structural difference dictates how contracts execute and settle. Arbitrum relies on Ethereum for security and settles gas fees in ETH, offering full EVM compatibility along with its Stylus environment for Rust, C, and C++. NEAR Protocol runs an independent validator network where gas is paid in NEAR, executing contracts written in Rust or JavaScript via WebAssembly. By mid-2026, Arbitrum secured over $12.3 billion in value with a 7-day dispute window for native exits. In contrast, NEAR provides 1.2-second finality with 600-millisecond block times, handling cross-chain intents across more than 35 external blockchains without native EVM support.
Quick verdict
The core distinction is network architecture and settlement layer. Arbitrum anchors directly to Ethereum security, giving teams full EVM compatibility and access to Ethereum liquidity with gas paid in ETH. NEAR operates an independent proof-of-stake Layer 1 with rapid 1.2-second finality and cross-chain execution rails spanning dozens of networks.
Choose Arbitrum if you build or trade within the Ethereum ecosystem, require native EVM or Solidity support, and prefer paying gas in ETH while taking advantage of sub-second block times and dedicated Orbit appchains.
Choose NEAR Protocol if you need fast Layer-1 finality without waiting for rollup dispute windows, write contracts in JavaScript or Rust, or want native cross-chain routing across non-EVM chains like Bitcoin and Solana.

FAQ
Is Arbitrum EVM compatible compared to NEAR Protocol?
Arbitrum is fully EVM compatible and runs existing Solidity contracts alongside Rust via Stylus. NEAR Protocol is not natively EVM compatible at its base Layer 1, executing contracts compiled to WebAssembly using Rust or JavaScript.
What token pays for transaction gas on each network?
Arbitrum transactions settle gas fees in ETH, the native currency of Ethereum Layer 1. NEAR Protocol settles transaction gas using its own native token, NEAR.
How does settlement time compare between Arbitrum and NEAR?
NEAR reaches Layer-1 finality in 1.2 seconds across its sharded proof-of-stake validators. Arbitrum processes transactions in roughly 0.25 seconds on its offchain sequencer, but native bridge withdrawals back to Ethereum require a 7-day fraud-proof dispute window.
Which network has more total value secured?
Arbitrum secured over $12.3 billion in ecosystem value by mid-2026. NEAR Protocol held approximately $230 million in network total value locked as of October 2026.
