Verify seed words independently.
SeedWitness calculates seed words from entropy supplied via dice or coin flips so you can check if a seed phrase you're given is calculated honestly.

SeedWitness shows the entropy calculated from your dice rolls or coin flips alongside the resulting seed words.
Enter the same entropy into another compatible implementation, such as Ian Coleman’s BIP-39 Mnemonic Code Generator. The intended use is to generate reference seed words on both SeedWitness and another device, then assess whether their outputs agree. Those reference seed words need not—and ought not—be the seed words used, or intended to be used, to secure bitcoin.
