Common questions
What happens to my stamps if I cancel?
Your existing stamps stay verifiable forever — they live on MegaETH, not on our servers. Cancelling just stops you from creating new ones at the paid tier limits.
Do unused stamps roll over to next month?
Free tier — no rollover. Paid tiers — up to 50% of unused stamps roll over for one month, capped at 2x your monthly limit.
What if TruthStamp shuts down?
Your stamps survive. They live on MegaETH and Arweave, both of which work without us. We've also open-sourced our verifier — so anyone can verify your proofs forever, even if our website is gone. Read our permanence promise →
Can I pay with crypto?
Yes. We accept USDC, ETH, and MegaETH's native USDM stablecoin. Crypto payments come with a 10% discount for the first year.
Is there an annual discount?
Yes — 20% off when you pay yearly. Toggle the billing switch above to see annual pricing.
