Pool MigrationOrchard → Ironwood
Ironwood is the newest shielded pool. When it activated, Orchard closed to deposits — old Orchard notes must be spent across the turnstile to become Ironwood notes, and every crossing shows up in the pool value balances. This page follows that migration, straight from the chain.

▍How big is a typical crossing?
One point per transaction that moved value into Ironwood, from any source pool. Read it as: this share of crossings were this size or smaller.
Half of all crossings moved 1.62 ZEC or less, yet the average is 66.5 ZEC. 3% of transactions are dust under 0.01 ZEC — wallets sweeping change — while the largest 1% of transactions carry 64% of all migrated value. A typical migration is not a typical migrated coin: most coins cross in a few very large transactions.

Each Ironwood inflow is attributed to the pool that supplied the value inside the same transaction. These are cumulative inflows, not a balance: outflows are not subtracted, so the total sits above the live Ironwood balance by whatever has since left.
