Trading fees on Arcus follow a maker/taker fee-tier model: the rate you pay depends on whether your order adds liquidity (maker) or removes it (taker), and on your tier, which is driven by trailing trading volume.
This page is conceptual. Your current tier and the live fee schedule are returned by GET /v1/feetiers; always read fees from the API rather than hard-coding them. You can also check your latest fee tier from the Arcus portfolio page.

​
The model

  • Maker orders rest on the book and provide liquidity; taker orders execute against resting liquidity and remove it. Makers are charged less than takers, and high-volume tiers can earn maker rebates.
  • Tiers are determined by your trailing trading volume over a rolling window. As your volume grows, you move into lower-fee tiers automatically.
  • Funding payments are not a fee — they are transfers between traders. See Funding.

​
Current state

  • Spot trading is free at launch.
  • Perp fee tiers publish closer to launch — set to be competitive with leading perp venues, with maker rebates for market makers and high-volume traders. Specific rates per tier are read from the API once live.
Because the exact schedule is still being finalized and will change over time, this page deliberately avoids quoting rates. GET /v1/feetiers is the source of truth, and your portfolio page shows your current tier.

Account costs beyond trading fees

  • Deposits/withdrawals: Arcus charges no fee of its own; USDG deposits and withdrawals carry zero fees. Third-party processing or conversion costs (for card/fiat or cross-chain routes) are shown upfront. See Onboarding & deposits.
