According to Whale Alert (blockchain transaction tracker), 700 million XRP was placed back into escrow within 24 hours after Ripple unlocked 1 billion XRP.
Blockchain tracking account Whale Alert reported that 700 million XRP was re-locked into escrow in the past 24 hours after Ripple unlocked 1 billion XRP. Escrow (funds locked under preset release conditions) is a mechanism Ripple has long used to manage XRP supply by releasing tokens on a schedule and re-locking any portion not used. The reported transactions indicate that a large share of the unlocked XRP was returned to escrow rather than left in circulating supply.
