Lifetime Account
Sovereignty Guarantee.

A signed, tamper-proof record of every sale of an account that ever flowed through TITAN. Each row in the HMAC-SHA256 chain is signed against the previous one — altering a single entry afterwards breaks the whole chain.

On listing creation the seller's recovery email transfers to TITAN, the password is rotated by TITAN, and 2FA is re-enrolled to TITAN. The listing cannot go live until all three are done. At sale the buyer connects their own recovery + 2FA and the TITAN alias is removed. The seller reclaiming the account becomes mathematically impossible.

The system logs into the account itself and extracts attributes like rank, skins and agents — verified data, not seller claims. The auto-login can occasionally fail (Riot/Epic challenges); when it does, the listing drops into a manual verification queue and an operator fills the same schema by hand.

After the sale every key to the account (recovery, 2FA, optional phone) transfers to the buyer. Sigmamarkt keeps no handle on the account after delivery — the buyer uses it knowing it belongs only to them.

You can verify a provenance receipt publicly at sigmamarkt.com/verify/{receipt}. Chain integrity shows as a green badge — red if broken.

A sale that happened outside Sigmamarkt is marked as a 'gap of unverified history' in the chain. This gives the buyer transparency: part of the account's past took place off-platform.
