zkEMBERS docs_

01Overview_#

zkEMBERS is a collection of 3,333 pixel identities on Solana. You mint one by burning $EMBERS, the project's pump.fun coin. Every $EMBERS trade pays a creator fee, and all of it goes to holders: the fees are converted into native, shielded Zcash and paid out per NFT to each holder's Zcash address.

02The collection_#

zkEMBERS are chunky 24×24 pixel busts on black, each one a single colour family, with the crown burning off and rising as embers: the burn that minted it.

Generative art_#

Nobody draws an individual zkEMBER, and nobody can choose one. Each image is generated deterministically from the NFT's asset address, a fresh keypair created at mint time. The same address always draws the same image, so the art can be re-rendered and checked by anyone, forever. Wallets and marketplaces load a 1000×1000 PNG from /api/nft/<asset>/image.

Traits_#

That is roughly 97,000 trait combinations for 3,333 pieces. Two pieces can share every trait and still differ: the burn pattern, embers and smoke are placed pixel by pixel from the address.

Token standard_#

Every zkEMBER is a Metaplex Core asset in one collection, the current Solana NFT standard supported by Phantom, Solflare, Backpack, Tensor and Magic Eden. One account per NFT, cheaper rent and lighter transactions than legacy Token Metadata.

03Minting_#

What it costs_#

One atomic transaction_#

A mint is a single Solana transaction. Its instructions either all succeed or all fail, so you can never burn without receiving the NFT, or the reverse.

compute budget        150k CU, priority fee
system::transfer      0.1 SOL  you → project wallet
token::burnChecked    100,000 $EMBERS  from your token account
core::createV2        new zkEMBER in the collection, owner = you

signers:  you (fee payer, token owner)
          the new asset keypair (server)
          collection authority (server)

Step by step_#

1. 1
   Connect
   Any Solana wallet through the connect dialog. The site checks you hold enough $EMBERS and SOL before building anything.
2. 2
   Prepare
   The server reserves the next free number, generates the asset keypair, builds the transaction above and signs it as the asset and as the collection authority.
3. 3
   Sign
   Your wallet shows one transaction. Signing adds your signature as fee payer and token owner. Nothing moves until it is broadcast.
4. 4
   Submit
   The server checks the transaction is byte-for-byte the one it prepared for that asset, then broadcasts and waits for confirmation.
5. 5
   Reveal
   Your zkEMBER appears in your wallet and on the site. Its art is drawn from the asset address.

Numbers & reservations_#

Numbers run from #0001 to #3333. Prepare reserves the lowest free number under a database lock, so two people can never get the same one. A reservation that is not confirmed within about three minutes (longer than a Solana blockhash lives) is checked on-chain: if the asset exists it is marked minted, otherwise the number is freed for the next minter. A wallet can hold at most two mints in flight.

When a mint fails_#

04Earning ZEC_#

Creator fees_#

$EMBERS carries a 2% creator fee, paid by pump.fun on every buy and sell, on the bonding curve and after graduation to the AMM. The fee accrues in a creator vault that only the launch wallet can collect. When the coin trades against ZEC, the fee is already ZEC on Solana (A7bd…XaS); a SOL-paired coin pays it in SOL.

The keeper_#

A keeper process runs a pass every 60 seconds. Each pass, in order:

1. 1
   Settle
   Poll open NEAR Intents swaps and payouts. Credit the pool with what actually landed; mark payouts paid with their Zcash transaction.
2. 2
   Collect
   Once at least 0.002 ZEC (or 0.02 SOL) has accrued, claim the creator fees, including fee buckets left on the curve or pool by newer trades. Only what the claim measurably added is credited.
3. 3
   Sweep
   Once 0.005 ZEC (or 0.05 SOL) is collected, send it through NEAR Intents into native ZEC held in the keeper's intents account: the pool.
4. 4
   Round
   Once the pool holds 0.01 ZEC, snapshot every zkEMBER and split the pool equally per NFT.
5. 5
   Pay
   Every holder with an address and at least 0.005 ZEC unpaid gets a withdrawal straight to their Zcash address.

NEAR Intents_#

The conversion uses NEAR Intents (1Click), a cross-chain settlement network. The keeper asks for a quote (1% slippage cap), sends the collected ZEC or SOL on Solana to a one-time deposit address, and solvers deliver native ZEC into the keeper's intents account. Payouts run the same way in reverse: ZEC moves from that account to a withdrawal intent that delivers it to the holder's address on the Zcash chain. No wrapped token, no bridge to babysit. If an intent is refunded, the amount returns and is retried.

Rounds_#

A round takes a snapshot of every live zkEMBER and its current owner from Helius (DAS). The pool is divided by the number of NFTs, and each owner is credited one share per NFT. Shares below 0.00001 ZEC roll into the next round instead of being lost.

per_nft      = pool / nfts_in_collection
your_share   = per_nft × nfts_you_hold

Payouts_#

Credits add up across rounds. When your unpaid total reaches 0.005 ZEC and you have a payout address, the keeper sends it in one withdrawal. Payouts are automatic; there is nothing to claim. You can track each one, with its Zcash transaction, on the Rewards page.

Worked example_#

An illustration, not a forecast. Yield depends entirely on trading volume.

ZEC at $1316.46 (live). Before 1% swap slippage cap and NEAR Intents fees.

05Payout addresses_#

Address types_#

Getting one_#

Install a Zcash wallet that supports shielded addresses (Zashi, YWallet and others), create a wallet, and copy its receiving address. Most modern Zcash wallets show a unified address (u1…) by default.

Setting it_#

1. 1
   Open Rewards
   Connect the Solana wallet that holds your zkEMBERS.
2. 2
   Paste the address
   The site checks its shape, then asks NEAR Intents (a dry-run withdrawal quote) whether it can deliver to it.
3. 3
   Sign a message
   Your wallet signs a text message naming your wallet, the address and a timestamp. This is not a transaction: no fee, nothing moves, and the signature expires after 10 minutes so it cannot be replayed.

zkEMBERS payout address
wallet: <your Solana wallet>
asset: ZEC
to: <your Zcash address>
issued: <timestamp>

You can change the address any time the same way. The newest one is used for every payout that has not been sent yet.

No address yet_#

Your shares still accrue every round. They wait under your Solana wallet until you set an address, and the next keeper pass then pays the whole balance. Rewards follow the wallet that held the NFT at each snapshot.

06Transparency_#

What is on-chain_#

Explorers_#

The home page activity feed lists mints, rounds, payouts and fee sweeps as they happen, each linking to its transaction: Solana on solscan.io, Zcash on mainnet.zcashexplorer.app. Every NFT page links its asset and its mint transaction.

07Security & trust_#

Keys we hold_#

As collection update authority the keeper could change collection metadata; it never transfers or burns assets, which only the owner can do in Metaplex Core.

Guarantees_#

1. 1
   Atomic mint
   Fee, burn and NFT are one transaction. Partial outcomes are impossible.
2. 2
   Exact relay
   The server only broadcasts the exact message it prepared for that asset; a modified transaction is rejected.
3. 3
   No custody
   The site never holds your NFTs or tokens. Your wallet signs every action that touches your assets.
4. 4
   Measured credits
   The keeper credits only what each fee claim measurably added, never more than pump.fun reports owed.
