Fees

QuiverDex fee#

A platform fee is the amount charged by the product for its service, where applicable. The interface must show the rate, charged asset, and whether it is taken from the input or output. The quote must clearly identify whether the displayed output already reflects that fee.

A future discount applies only to the costs explicitly covered by its terms. A reduced QuiverDex fee does not automatically remove pool fees or network costs.

Pool fees#

Liquidity sources may include their own trading fees in the quoted exchange result. Where these costs are already reflected in the output, label them Included in quote instead of subtracting them again. If a precise separate breakdown is unavailable, disclose that limitation rather than inventing one.

Estimated network cost#

Robinhood Chain uses ETH for gas. Its documented fee model contains execution and data-posting components, which standard fee estimation bundles into the transaction cost.^[1] The network estimate is separate from QuiverDex's platform fee.

An approval transaction may have an additional network cost. The review flow should explain whether the displayed estimate includes only the swap or also the preceding wallet actions. Actual execution cost can differ from an estimate.

Minimum received#

Minimum received is not a fee. It is the lowest net output the reviewed swap is permitted to accept, according to the implemented transaction protection. If this condition is not satisfied, the intended atomic swap should revert rather than silently deliver less. This behavior must be enforced by the actual contract.

The UI must show the same minimum as the transaction plan. Token decimal precision and integer rounding matter; do not recompute protection using imprecise floating-point arithmetic.

Illustrative calculation#

This example assumes an output-side fee. It is not QuiverDex's announced pricing.

The calculation is 998.50 × (1 − 0.005) = 993.5075. A network cost paid separately in ETH is not automatically deducted from this output amount again. The production quote and contract determine the final atomically rounded values.

Failed transactions#

Rejecting a request in the wallet before submission is different from a transaction being included on chain and failing. On-chain execution consumes computational resources; a reverted transaction can still incur network fees.^[2] Do not assume all costs are refunded simply because the swap did not complete.

If an earlier approval succeeded and a later swap fails, the approval and its cost are separate. Review outstanding allowances and the relevant receipts.

Before you confirm#

Check the expected net output, minimum received, applicable platform rate, pool-fee treatment, estimated network costs, and quote expiry. Refresh an expired quote rather than confirming outdated terms. Read Routing and Safety for related details.
