# Settle a queued vault deposit

> Curator-only endpoint that settles a pending deposit request by signing a mint approval at a quoted share price (USD per share). Takes the request id and the user's deposit-action hash, mints the corresponding shares, and returns the settlement result. Requires the curator mint-and-burn permission.
