ON-CHAIN INFRASTRUCTURE
On-Chain Programs
The backbone of the SOLANA DEADS ecosystem. Verified Solana programs powering staking rewards, the GraveMint multi-chain mint engine, the GraveMarket NFT marketplace, and more — with two retired programs kept on record below.

GraveMintMint Engine
GRVMNt7b2Pojom2fTF6HytLRm2hfQCN8iHm9wLvSFWVJ
The GraveMint mint engine is the on-chain Solana program powering the GraveMint launchpad. It manages collection registration, phased minting, IPFS metadata, asset and collection plugin management, and delegated mint authority via PDAs — supporting both new collections and prepared migrated collections.
Key Functions
Multi-Chain Reach
While this on-chain program is Solana-native, the GraveMint launchpad surfaces it alongside EVM mint engines on Ethereum, Polygon, Base, Abstract, ApeChain, and more — giving creators a single dashboard to deploy collections across Solana, EVM, Sui and the XRP Ledger.
GraveMarketMarketplace
GRAVENNCLF1daKeBAHCvbD2Pw12xLMY6GGM2e4LChwcd
The GraveMarket marketplace is the Solana-side on-chain program powering the GraveMarket NFT marketplace. It is the first marketplace program to natively support all major Solana NFT standards in a single contract — Core, Legacy Metaplex, programmable NFTs (pNFT), compressed NFTs (cNFT), and Token-2022 — with both SOL and SPL token-denominated trades.
Multi-Standard Support
Core
MPL-Core assets with full plugin support
Legacy
Original Metaplex NFTs (Token Metadata)
pNFT
Programmable NFTs with rule sets
cNFT
Compressed NFTs via state compression
Token-2022
Native SPL Token-2022 NFTs
SPL Currencies
Trade in SOL or any SPL / Token-2022 currency
Key Instructions
Multi-Chain Marketplace
This program covers the Solana side of GraveMarket. The product itself spans Solana plus every major EVM network (Ethereum, Polygon, Base, Arbitrum, Optimism, Abstract, ApeChain, Avalanche, BNB, Berachain, Cronos, Soneium) — with EVM trades handled via on-chain marketplace integrations on each network.
GraveSwapMPL-404 Engine
GRvpAqXy1CKTQJ9qEVMFnvUqu1pVgzHgRVwBGsRdsWap
The GraveSwap program is the on-chain MPL-404 swap protocol — Solana's answer to ERC-404. Each pool fixes a collection's swap rate against an SPL or Token-2022 mint, then handles both directions atomically: deposit an NFT to mint tokens, or pay tokens to draw a random NFT from the pool's escrow. Per-pool escrow PDAs, slot-hash randomness for fair picks, and ed25519-authorized creator actions.
Key Functions
How it surfaces
Pools are deployed and managed via the GraveMint launchpad. The collector and creator mobile apps surface the same swap UI. When a collection has an active pool, GraveMarket flags it with an MPL-404 badge and routes Buy/List actions away from NFTs that are currently held in the pool's escrow.
GraveStakeStaking Engine
GRv7q7Tff1yEEwvuuBin9xySF35pk7Vc4sVyJLM9wSTK
The GraveStake program is the on-chain no-code staking and rewards protocol. Any creator can launch a staking pool for an NFT collection — Legacy, pNFT, MPL Core, or compressed — or for a fungible token (SPL or Token-2022). Stakers keep custody on-chain while earning hybrid rewards, with lock-tier multipliers that pay more for longer commitment.
Key Functions
Deployments
A Solana Anchor program plus EVM staking-factory contracts deployed to 12 EVM mainnets at CREATE2-deterministic (identical) addresses.
EVM Staking Factory: 0x77F7455A1EcbdaA6a54317a9Ea7327c67cf3F87F
How it surfaces
Pools are launched and managed from the GraveStake creator dashboard at gravestake.io, each with its own branded stake page. Staking fees feed the same $DEADS buyback-and-Harvester flywheel as GraveMint and GraveMarket, recycling value back to holders across the ecosystem.
GraveDrawAuctions & Raffles
GRVegmwpsnJ3MQwvy7BbLcnmGQraRiXgERnGFGCPdrAw
The GraveDraw programs power on-chain NFT & token auctions and raffles across Solana and every major EVM network. Prizes are escrowed on-chain before a draw goes live; auctions run English ascending-bid with anti-snipe, and raffles pick up to 5 winners with provably-fair commit-reveal randomness that anyone can verify. Trustless throughout — the protocol never custodies funds or prizes.
Key Functions
Deployments
Solana Anchor program plus UUPS auction/raffle contracts deployed to 12 EVM mainnets at CREATE2-deterministic (identical) addresses.

Retired Programs
These two programs are closed on mainnet and are listed here for the record. Their work was consolidated into GraveStake — which now runs the harvest and every staking and rewards mechanism they provided, open to any collection rather than just Solana Deads. The 1.11% $DEADS transfer fee they were built around is still live.
Solana Deads HarvesterFee Router
DEADS3ucNHjN8iz3Cw65joYxgVdguNsjytHRqCs7QvzA
The Solana Deads Harvester (also known as solanadeads-fee-router) was the standalone fee-router program for the $DEADS ecosystem. That program has been closed on mainnet.
The flywheel it served is unchanged: the 1.11% $DEADS transfer fee is still live on the Token-2022 mint. The withheld-fee authority now belongs to a PDA owned by the GraveStake program, and GraveStake's permissionless harvest crank performs the sweep and distribution the Harvester used to do.

Security & Verification
Retired program — the account stays on-chain, and the explorer reports it as closed.
CryptKeeperRewards Program
DEADZS7SrZMW5aGgXzgUis59iaQfjgdmnXMQuJJo7uAu
The CryptKeeper was the on-chain rewards distribution program behind the first generation of SOLANA DEADS staking. It handled NFT soft-staking, token hard-staking, and the distribution of rewards to holders. The program has been closed on mainnet.
Staking and rewards now run on the GraveStake program. The record below describes what CryptKeeper did while it was operating.
Dual Reward Systems
Manual Allocations
Admin-controlled rewards for special events, airdrops, and bonuses — used for community rewards and promotional distributions.
- Airdrop distributions
- Community bonuses
- Special event rewards
Streaming Rewards
Continuous accrual based on NFT/token holdings using a global index system. Rewards accumulated automatically over time.
- NFT soft-staking (no custody)
- Token hard-staking (locked)
- Real-time reward accrual
NFT Soft-Staking
NFTs stayed in the holder's wallet - no custody required. The program verified ownership on-chain at claim time.
No Lock-up
Stakers kept full control of their NFTs
Verified Ownership
On-chain verification at claim time
Rarity Weights
Rarity-based reward multipliers (planned, never shipped)
Token Hard-Staking
$DEADS tokens were locked in the program vault to earn streaming rewards, held in custody by the program.
Stake Tokens
$DEADS was locked in the program vault to start earning rewards
Earn Rewards
Rewards accrued continuously based on stake proportion
Claim Anytime
Accumulated rewards could be claimed without unstaking
Unstake
Tokens could be withdrawn anytime (proportional rewards forfeited)
Technical Features (While Active)
None of this went away with the program. Reward distribution, pooling, claim safety and the rest of this stack were consolidated into GraveStake — and are now open to every collection, not just Solana Deads.
Global Index System
Distributed rewards efficiently using cumulative index tracking
Collection Pools
Kept separate pools for different NFT collections and token staking
Circuit Breaker
Emergency controls that could pause operations if needed
Delegated Wallets
Supported linking multiple wallets to one account
Rate Limiting
Protected against claim spam and abuse
Analytics Tracking
Tracked on-chain metrics for pool performance and user engagement
Marketplace Detection
Identified NFTs listed on marketplaces for fair reward distribution
Leaderboards
Ranked top stakers and claimers on-chain
User Stats
Tracked all reward activity per user
Safety & Security (While Active)
Retired program — the account stays on-chain, and the explorer reports it as closed.
