Offchain Labs Launches 15-Minute Withdrawals For Arbitrum Orbit Chains

Arbitrum Orbit users can now withdraw their assets to the Ethereum mainnet in just 15 minutes.

On Oct. 24, Offchain Labs, the team behind Arbitrum, launched Fast Withdrawals for Orbit chains, offering 15-minute withdrawal finality for users. The service is also available to rollup-as-a-service (RaaS) providers leveraging Arbitrum’s infrastructure.

The feature eliminates the seven-day waiting period typically associated with optimistic rollups, such as the Arbitrum One network and Arbitrum Orbit chains. Arbitrum Orbit is a tech stack allowing developers to launch bespoke Layer 2 or Layer 3 networks that settle transactions on Arbitrum One or Ethereum.

“This is a game-changer for how people interact with blockchains, making transactions faster and more seamless, and bringing the experience closer to what people expect from traditional financial systems,” said Steven Goldfeder, CEO and co-founder of Offchain Labs.

Arbitrum Orbit is gaining popularity as a tech stack for networks hosting gamefi applications. Four of the top 10 Ethereum scaling solutions by daily throughput leverage Arbitrum Orbit, including Xai, PlayBlock, PoP Apex, and ApeChain, according to L2beat.

Fast Withdrawals

Fast Withdrawal transactions are processed by a committee of validators. Should the validators unanimously agree on the transaction’s validity, the state changes associated with the transaction are immediately confirmed.

By contrast, optimistic rollups impose a seven-day delay on withdrawals to the Ethereum mainnet, allowing validators or users to identify and challenge fraudulent transactions.

Several Orbit chains have already committed to integrating support for Fast Withdrawals in the coming months, including ApeChain, Cheese, Nova, Sanko, and Xai. Prominent RaaS providers including Alchemy, Ankr, Caldera, and Gelato have also pledged to support the feature.

Offchain Labs emphasized the benefit Fast Withdrawals can unlock for throughput-intensive dApps, including web3 games and socialfi applications.

Stylus upgrade

The launch of Fast Withdrawals comes after Offchain Labs shipped Stylus, an upgrade to Arbitrum’s core Nitro stack, on Sept. 3.

Stylus allows developers to create applications using WebAssembly-compatible languages, including Rust, C, and C++. Previously, Arbitrum chains only supported Solidity, Ethereum's native programming language.

Stylus is supported by the Arbitrum One and Arbitrum Nova Layer 2 networks, in addition to the Orbit stack.

Arbitrum One is a general-purpose Layer 2 solution, while Arbitrum Nova is optimized for applications requiring a high volume of low-cost transactions, such as gaming and social protocols. Arbitrum One is the largest Layer 2 network with a total value locked (TVL) of $13.85 billion, according to L2beat.
