Arbitrum (ARB) is the governance token of the Arbitrum network, a Layer 2 scaling solution built on top of Ethereum. Users frequently swap ARB when moving between the Arbitrum Layer 2 environment and Ethereum mainnet, or when repositioning across DeFi protocols that operate on either network. Because ARB exists on both Arbitrum and Ethereum, selecting the correct network for your destination is one of the most important steps before confirming a swap.
Before swapping ARB, confirm which network your receiving wallet or platform expects — Arbitrum (Layer 2) or Ethereum mainnet — since sending to the wrong network can result in funds that are difficult or impossible to recover without technical steps. Fees and settlement behavior differ meaningfully between the two networks, so the network you choose affects more than just speed. No memo or destination tag is required for ARB on any supported network. The exchange widget on Zest displays the rate and network details before you confirm, giving you a chance to verify everything looks correct. Confirmation times can vary depending on network conditions, so allow for some flexibility after the transaction is broadcast.
