Arbitrum (ARB) is a scalable, secure and decentralised protocol for smart contracts. Learn more about Arbitrum, as well as how to buy ARB and where to store it.
Introduction to Arbitrum (ARB)
Developed by Ed Felten, Steven Goldfeder and Harry Kalodner (Offchain Labs), Arbitrum is a layer 2 solution that improves upon Ethereum’s (ETH) capabilities by drastically reducing fees and increasing transaction speeds.
Arbitrum achieves this by employing optimistic rollup technology, which executes transactions off-chain and reduces congestion on the Ethereum mainnet. This also means that Arbitrum can utilise Ethereum’s high levels of security.
The Arbitrum network uses ARB as its native governance token.

Where to buy Arbitrum
ARB was launched in early 2023. Upon launch, 11.62% of the token’s circulating supply was airdropped to early supporters, with 1.13% given to developers.
Since then, ARB has been listed on several different cryptocurrency exchanges and trading platforms, including eToro. On most of these platforms, you can purchase ARB directly using fiat currencies.
Alternatively, decentralised exchanges (DEXs) allow users to trade cryptocurrencies directly, meaning you could potentially purchase Arbitrum (ARB) with assets such as BTC or XRP.
Because of the strong early adoption, ARB can now be purchased on several cryptocurrency exchanges, both centralised and decentralised.
Tip: Arbitrum partnered with Immunefi to create a $2 million bug bounty solution, ensuring constant monitoring of any potential vulnerabilities.
How to keep and store Arbitrum
Once you have purchased Arbitrum, you must store it safely. Some cryptocurrency platforms will allow you to store it directly on the platform itself, while others will direct you to a cryptocurrency wallet. These are generally deemed to be “hot” — if they are connected to the Internet — or “cold” — if they act as a physical storage device.
For Arbitrum, there are lots of good, secure wallets to choose from:
- Rainbow: A brightly coloured, user-friendly Ethereum wallet that supports non-fungible tokens (NFTs), ARB and other Ethereum-based cryptoassets.
- Metamask: A popular browser extension wallet that can store Ethereum-based assets such as Arbitrum (ARB).
- Ledger: With various devices available, Ledger is a leader in the cold wallet space. Users can store a range of cryptocurrencies offline, including ARB.
Learn more about Arbitrum
It is important to note that Arbitrum did not start as a cryptocurrency token. Offchain Labs, the company behind Arbitrum, was founded by computer science professors from Princeton University with the intention of bringing smart contract scalability to Ethereum.
Because of their Solidity coding, decentralised apps (dApps) built on Ethereum can migrate directly to Arbitrum to boost performance and security. This aims to greatly lower gas fees and improve transaction speeds, offering developers a more usable platform.

Final thoughts on investing in Arbitrum
Offchain Labs has introduced a decentralised autonomous organisation (DAO) for the Arbitrum One and Arbitrum Nova networks, putting governance responsibility into the hands of token holders.
This move toward decentralisation has captured the attention of cryptocurrency investors, as the Arbitrum community is able to shape the protocol’s future. Those who hold ARB tokens have voting power proportional to their holdings, allowing them to directly influence decisions related to the network’s development and future direction.
However, like all investments, Arbitrum comes with certain risks. Potential investors should thoroughly evaluate their risk tolerance and financial position before investing in ARB.

FAQ
- Should you buy Arbitrum (ARB)?
-
The question of whether you should buy Arbitrum (ARB) depends on several factors, such as your investment goals, risk tolerance and market research. ARB presents potential growth due to its innovative technology, which aims to solve Ethereum’s scalability problems. However, cryptocurrencies can be incredibly volatile, so there is no guarantee that the price of ARB will increase, and even if it does, it may not stay at those levels.
- What is a DAO?
-
A DAO is a decentralised autonomous organisation, embodied in computer code and executed on a distributed blockchain. Its members manage it and govern it through a consensus protocol, making decisions and rules based on pre-programmed instructions.
The primary goal of a DAO is to enable total transparency and complete shareholder control, removing the need for a traditional, centralised authority.
- What is a layer 2 blockchain?
-
Layer 2 solutions, such as Arbitrum, are built on top of layer 1 blockchains. They are designed to improve transaction speeds and reduce associated costs, without modifying the main blockchain. These solutions offload some data and operations from the main chain to a secondary chain, thus, increasing the network’s overall transaction capacity.
