Coinbase published a notice on September 29 stating that 29 assets no longer count toward eligible collateral for perpetual futures on Coinbase International Exchange. The change concerns collateral — the assets an eligible trader can use to support open leveraged positions — and does not announce a spot-market delisting or any removal of tokens from customer ownership.

That makes the practical impact narrower than the headline may suggest. A holder who does not use Coinbase International Exchange perpetuals may see no direct change. A trader whose open positions relied on one of the named assets, however, could have less recognised collateral behind the same portfolio.

The 29 Affected Assets — and the Ones Left Out

The notice names AERO, ALGO, APT, ARB, ATOM, AVAX, BCH, BNB, BONK, CRV, DOT, FARTCOIN, FIL, ICP, INJ, JASMY, LTC, ONDO, PENGU, OP, PEPE, PUMP, SEI, SHIB, SUI, UNI, VET, XLM and ZORA.

SOL, XRP and LINK do not appear in the September 29 removal notice. They should not be described as part of this particular collateral change unless Coinbase publishes a separate update.

How Eligible Collateral Becomes Margin Capacity

Perpetual futures are leveraged derivatives contracts with no fixed expiry date, and on Coinbase International Exchange they are traded in portfolios that post collateral. The relevant figure is not a token's market value alone, but the portion of that value Coinbase recognises for margin. Under the exchange's cross-collateral rules, an asset's market value is adjusted through a collateral weight after a haircut. The haircut reflects the risk that the asset could lose value or be difficult to sell quickly during market stress.

Cross-collateral arrangements of this kind are a common feature of crypto derivatives venues: rather than requiring only cash or stablecoins, the exchange lets a range of digital assets support positions, with the venue itself setting which assets qualify and at what weight. That structure also explains how a single notice can change the margin picture for holders of many different tokens at once.

The distinction becomes clearer when a portfolio relies on an affected token to carry an open position. In a simplified example, $10,000 of an altcoin that previously counted at a hypothetical 80% collateral weight would have contributed $8,000 to margin. Once that asset is no longer eligible, its contribution becomes zero. The trader still owns the $10,000 balance — what changes is the asset's role inside the perpetuals risk system. The example is illustrative; Coinbase's actual collateral weights and account limits can differ by asset and portfolio.

Coinbase says collateral liquidations may occur automatically when a portfolio's current margin falls below its maintenance requirement. The proceeds are used to address the shortfall before the exchange resorts to closing positions.

Who Is Affected, and Who Is Not

The effect depends on where a token is held and whether it was supporting an open perpetual position. Coinbase International Exchange derivatives are available only to eligible clients in selected regions outside the United States. Per Coinbase's product guidance, users transfer USDC or eligible collateral into a dedicated perpetuals portfolio to access the product.

For perpetuals users holding an affected asset, available collateral and the maintenance-margin buffer may need review. For perpetuals users relying on other eligible assets, the rule may not alter their immediate collateral position, though cross-margin exposure remains relevant. For spot holders and self-custody users, the notice does not describe any change to token ownership or activity outside this specific collateral system.

Portfolio Adjustments Are Not Evidence of Spot Selling

Some affected traders may add USDC or another accepted asset, reduce their open exposure, or transfer balances between venues. Those are possible responses to a margin-rule change, especially for portfolios with little room above their maintenance requirement. They are not evidence of broad spot selling across the market.

The new rule applies to a defined collateral basket on one derivatives venue. Coinbase has not said why it removed the assets, how much collateral they represented beforehand, or whether the decision reflects a view on any token's future price. That distinction should shape how the announcement is read: an exchange can tighten the assets it recognises for risk management without changing whether a token is tradable, held elsewhere or used in another financial product.

What Affected Traders Can Check

• Where the token is held: a balance in a perpetuals portfolio can have a different effect from the same asset held outside it.
• Available collateral and maintenance margin: these figures show the buffer supporting current positions.
• The latest accepted-collateral list: replacing one token with another may not produce the same margin value, because weights and limits vary.
• Open-position size: position size, collateral value and unrealised profit or loss work together in the portfolio's risk calculation.

The Key Is Recognised Collateral

Coinbase's update does not settle the outlook for ARB, ONDO, AVAX or the other affected assets. It changes a specific function they previously served inside one leveraged trading system. For affected perpetuals users, the practical issue is recognised collateral rather than token ownership: a balance may remain in an account while no longer supporting open leveraged positions.

Because the collateral basket is maintained by the exchange, any further adjustments to eligibility would arrive through Coinbase's own notices, making its published collateral documentation the reference point for tracking this list from here.
