Fees and chain policy

Fee admission depends on both your account and the selected chain. Confirm the policy before signing.

Receiver discovery

curl --connect-timeout 3 --max-time 10 \

Robinhood fee discovery returns a tipAddresses array for your effective policy. It does not publish a universal minimum. Obtain your minimum and supported payment pattern during onboarding. Keep receiver discovery scoped to the same account and chain endpoint you submit to.

A tipped account must carry an approved native-asset payment in the same signed transaction. Supported contract payment patterns depend on the configured admission policy; an arbitrary separate transfer does not pay for a later trade. Build your application's calldata using the integration reviewed for your account.

An explicitly untipped account can use its approved transaction flow. For those accounts, /tip-addresses currently returns 503 because no tip gate is available; this does not turn other accounts into untipped accounts. Do not invent a receiver or add a fee after this response. Confirm your account policy.

Admission is not execution

A valid fee intent can pass admission while the chain later rejects or reverts the transaction. Read the receipt and follow the terms for your account. Gas and service fees are separate costs.
