NFT Identity
Your on-chain identity
Every participant in DeadMKT holds a single trustee NFT. It is soulbound (non-transferable), it is your identity on the network -- it links your node to your on-chain escrow, tracks your participation, and anchors your membership.
Think of it as your membership card, except it's cryptographic, on-chain, and can't be faked -- or sold.
The three addresses (DMKT14)
One NFT, three roles:
- Trustee -- the keystore-derived address your node operates from (your "hot" key). It owns the NFT and signs everything: orders, settlements, heartbeats, and every withdrawal or exit.
- Sponsor -- the capital provider. Pays the membership fee at mint and is recorded immutably on-chain; the sponsor receives the membership refund when the NFT is eventually burned, no matter who signs the burn. If you fund yourself, sponsor = trustee.
- Payout -- where trading profits and exit proceeds are sent. This is not on-chain: it lives in your node's config (
payout_address) and is passed as the recipient on each withdrawal. Point it at a cold wallet.
The setup wizard asks for the payout address first, then the sponsor (default: your trustee address). See the operator playbook for the full security model.
The membership fee
Minting the NFT costs a membership fee (1,000 SUPRA at current parameters), paid by the sponsor into the protocol's operations treasury. The fee is what keeps the protocol running without any company behind it -- it funds the on-chain automation, randomness subscriptions, and infrastructure.
It is partially refundable: when the NFT is burned, the sponsor receives a time-decayed refund -- starting at 95% of the fee and decaying by 50 SUPRA per 30 days of membership, reaching zero after roughly 19 months. Your membership is a subscription paid by staying; leave early and most of the fee comes back.
Registration
After your NFT is minted, the wizard registers you as a trader on the escrow contract. This:
- Links your NFT to your escrow account
- Sets your withdrawal rules (holding period, rushed-withdrawal permission)
- Enables deposits, trading, and settlement
One identity per participant
Each trustee address has one NFT. Your trading history, settlement record, and escrow balances are all tied to it. If your NFT gets blocked (for commit violations, for example), your ability to trade is affected -- but never your ability to eventually exit: a blocked NFT is frozen only during the enforcement grace window, and every state has an exit path.
This is by design. Reputation is meaningful when identity is persistent -- and persistence is meaningful when the identity can't be bought or sold.
Leaving
Two layers of exit, both permissionless:
- Withdraw -- drain your escrow as SUPRA (holding-period path, or the faster penalized "rushed" path) while keeping your membership.
- Burn-exit -- retire the NFT itself with a single trustee-signed call. The entire escrow remainder converts to SUPRA at the fixed peg and goes to your payout address; the sponsor receives the time-decayed refund; the NFT is destroyed. Nothing is stranded, nothing needs permission.
If a member disappears for good, anyone can clean up after the abandonment windows pass -- with all proceeds forced to the original trustee and sponsor, never to the caller. See the playbook's exit section and janitor calls for the full rules.
No lock-ups beyond what you configured. No withdrawal fees. No "please contact support." Your money, your choice, always.
