Stamp Seed’s 2 of 3 Sharding Plates give you a simple way to split your 24-word recovery phrase across three separate titanium plates.
This method is designed so that any two of the three plates can restore your full backup, but no single plate contains all 24 seed words on its own. This helps reduce the risk of total exposure if one plate is lost, stolen, or accessed by the wrong person.
Each set includes three titanium plates with unique word-number layouts:
Plate 1: Words 1–16
Plate 2: Words 9–24
Plate 3: Words 1–8 and 17–24
Together, the plates create overlapping coverage of your 24-word seed phrase. Store each plate in a separate secure location to create a backup system that is more private, resilient, and protected against a single point of failure.
Built from solid titanium, these plates are made for long-term offline storage and help protect your recovery phrase from fire, water, corrosion, impact, and the risks of paper or digital backups.
