About Arbitrum and Ethereum
Arbitrum (ARB) launched in 2023 — Ethereum scaling, secured by Optimistic rollup. The supply is capped at 10,000,000,000 ARB. For ARB deposits we wait for 20 confirmation(s) on Arbitrum One, which usually takes about 1 min.
Ethereum (ETH) launched in 2015 — Smart contracts, secured by Proof of Stake. There is no fixed maximum supply of ETH. For ETH deposits we wait for 12 confirmation(s) on ERC-20, which usually takes about 3 min.
Swapping ARB to ETH on noaml does not require an account. We quote the rate from multiple liquidity sources, include our 0.25% fee, and send the ETH directly to the address you provide. The minimum order is around $200 in ARB; there is no fixed maximum for manual orders.
