Sigmamarkt · Manifesto
What is Sigmamarkt?
Not another marketplace.
Gaming account marketplaces have one ancient wound: the seller pulls the account back after the money clears. Sigmamarkt makes that structurally impossible.
Why Sigmamarkt
G2G, LZT, Eldorado, GamerMarkt — they all copied the same model: seller hands email + password, buyer logs in, you hope the seller doesn't file a recovery form six months later. That hope translates into millions of dollars of lost accounts every year.
Sigmamarkt requires a Hand-off Ceremony the moment a listing opens. The seller relinquishes the account to us; we relinquish it to the buyer. Double-listing becomes impossible because the account is no longer in the seller's hands.
This platform makes one promise to everyone who trades — from a casual buyer looking for a smurf, to a power seller flushing a seasonal account: when the money is yours and the account is yours, nobody can pull it back.
Our three values
- 01
Transparency
Commission rates visible on every page. Dispute rules are public. Enforcement decisions land in an audit log — no silent bans.
- 02
Security-first
All account credentials are encrypted with envelope encryption; the master key lives in an external KMS. Decryption happens only at transaction time, through an audited channel.
- 03
Quiet premium
No bonus points, no shouting banners, no fake counters. Calm like a magazine, precise like a finance terminal. Honest marketing — if we don't have it, we don't write it.
Structural guarantee
Hand-off Ceremony + Provenance Chain
Two mechanisms doing together something competitors cannot: making it impossible for a seller to pull the account back.
Hand-off Ceremony
When a listing opens, the seller hands Sigmamarkt temporary, auditable access. Email recovery + 2FA + linked phone numbers all transfer. When the listing closes, all of it transfers to the new owner. The same account cannot be listed in two places — the seller no longer controls it.
Provenance Chain
Every sale produces an HMAC-signed receipt linked to the previous one. The buyer stays anonymous; the seller stays visible. If the account is ever re-sold, the old seller cannot deny the history — the chain carries proof.
