What is OP Mainnet/Optimism?

Launched in 2021, Optimism was created to address the scaling challenges faced by Ethereum mainnet. Despite’s high security, the Ethereum network can be slow and expensive as it processes every transaction and stores every piece of data. OP Mainnet takes a different approach: it processes transactions off-chain at high speed, batches them together, and submits only the final proof back to Ethereum.​

The key lies in the “optimistic” part of the name: OP Mainnet assumes these batches are correct by default. But anyone can challenge a suspicious batch by submitting a fraud proof, basically saying “that transaction didn’t actually happen that way.” If the challenge is valid, the network reverts and the bad actor loses their stake.​

This design delivers the best of both worlds: users get fast, cheap transactions, while the entire network maintains Ethereum-grade security through the fraud proof system and final settlement on Ethereum itself.​

As Ethereum’s most battle-tested optimistic rollup, OP Mainnet now secures billions in assets while enabling transactions at 85–95% lower fees than Ethereum mainnet.

Furthermore, OP Mainnet is also the cornerstone of the Optimism Superchain: a revolutionary network of interconnected Layer 2s built on the open-source OP Stack that’s become Ethereum’s scaling standard. 33+ teams have adopted it to launch their own Layer 2s (Base, Unichain, Ink & more).

The Optimism Superchain unifies these chains through shared infrastructure — assets flow between networks without traditional bridges, and developers benefit from coordinated upgrades.​

Cross-Chain Access to OP Mainnet

Historically, accessing OP Mainnet’s ecosystem required bridging from Ethereum mainnet, a multi-step process involving gas fees on L1 and managing wrapped assets. For users on Bitcoin, Solana, or other non-EVM chains, the friction was even greater with mostly centralized custodial solutions.

Today, THORSwap eliminates these barriers entirely. Some examples of usecases include:

• Swap Bitcoin directly to $OP on OP Mainnet (pay gas, participate in governance, use for DeFi and more)
• Swap Solana to ETH on OP Mainnet for instant DeFi access at 90% lower fees
• Convert XRP into $USDC on OP Mainnet to provide liquidity on Velodrome or Uniswap
• Trade Dogecoin or Zcash using USDT/USDC without touching centralized exchanges

The potential is endless, all executed non-custodial through THORSwap’s cross-chain infrastructure, powered by NEAR Intents via SwapKit for fast, secure settlement.​

Superchain Ecosystem meets Cross-chain Innovation

THORSwap’s OP Mainnet integration is an exciting new gateway to the fastest-growing scaling ecosystem in crypto: the Optimism Superchain.​

By connecting OP Mainnet, and by extension, the entire Superchain ecosystem, with Bitcoin, Solana, XRP, Dogecoin, Zcash, TRON and beyond, THORSwap enables capital to flow where opportunities exist across every major blockchain network, in a self-custodial and permissionless manner.

Whether you’re a DeFi trader seeking optimal execution venues, a stacker of $BTC, $ZEC or $DOGE, or an institution requiring enterprise-grade stablecoin rebalancing cross-chain, OP Mainnet on THORSwap opens possibilities that didn’t exist before in a decentralized manner.
