What the contract can do
Hedron lets HEX stakers mint HDRN against their stakes: once per day served, 1 HDRN per billion stake shares, so the amount falls as the HEX share rate rises. A stake can also be wrapped into a HEX Stake Instance (HSI) — an NFT issued by the HSI manager 0x8BD3d1472A656e312E94fB1BbdD599B8C51D18e3 — which can be traded, and HDRN can be borrowed against it; a loan left unpaid for 90 days can be liquidated at auction.
For the first 100 days after launch, minting earned a bonus that started at 10× and fell by 1× every 10 days; a second bonus depends on how much HDRN is borrowed compared with minted. Anyone can burn their own HDRN (proofOfBenevolence). The bytecode is identical on Ethereum and PulseChain.
Who controls it
No owner or admin functions. Every bonus paid to a minter is minted a second time to a source address fixed in the code, 0x9d73Ced2e36C89E5d167151809eeE218a189f801 — an ordinary wallet. On 2026-10-19 (block 27,837,276) it held 45,190,717,529,979.70 HDRN on PulseChain, about 26 % of the supply.
Marketplace royalties on HSI NFTs go to another fixed address, 0xF447BE386164dADfB5d1e7622613f289F17024D8, which also deployed the contracts; the HSI contract’s owner() returns it only for NFT marketplaces and grants no rights. The team publishes as PulseFusion and is pseudonymous; no person is publicly sourced. hedron.pro states that Hedron has no relation to HEX’s founder or development team.
History
HDRN and the HSI manager were deployed on Ethereum together on 20 February 2022 (05:01:14 UTC, block 14,240,942); on PulseChain since the fork in May 2023. Audit: CertiK, requested 20 December 2021 and delivered 17 February 2022 — 15 findings: none critical, three major (two acknowledged, one resolved), three medium and three minor (all resolved) and six informational; CertiK lists the team as not KYC-verified.
Activity: hedron.pro was last changed in 2022 and its code repository was last pushed in March 2022; the metadata server named in the contract, api.hedron.pro, returned a Cloudflare 523 error on 2026-10-17. The Telegram group had 3,707 members. On PulseChain on 2026-10-19 (block 27,837,276): supply 174,200,014,014,097.94 HDRN, 3,731 HSI NFTs, 41,615 holders.
Risks
Thin liquidity: about $2,500 in pools against WPLS and bridged stablecoins at block 27,837,276 (2026-10-19 12:30 UTC); about $8,300 including pools against HEX, PLSX and INC. Even modest sales move the price.
Concentration and dilution: about a quarter of the supply sits in the source wallet, and new HDRN is minted whenever HEX stakers mint. With the metadata server offline, marketplaces may not display HSI NFTs.
Verdict
Community-run, listed by editorial decision. Misses C4 (liquidity far below $25,000) and C5 (no team activity evidenced). C3 is met because the contracts have no owner; the source-address copies are an allocation fixed and documented in the code.
Where to use it
Interfaces that call these contracts, checked on 2026-10-19 — official ones first. A listing is not an endorsement: open apps from a bookmark, check the domain before you connect a wallet and read the risk line. Domains to avoid and what to do when an app is down: Interfaces.
-
hedron.pro
hedron.pro
OfficialPulseChainEthereum
Create and end HEX stakes as HSIs (HEX Stake Instances) and turn them into NFTs, mint and claim HDRN, take and repay HDRN loans against HSIs.
Risk: Unmaintained since November 2022: the liquidation-auction list depends on a retired data service, the built-in Uniswap page no longer exists, and only browser wallets connect. It offers unlimited HEX approvals.
-
Icosa × Hedron app
app.icosa.pro
OfficialPulseChainEthereum
HEX staking (optionally as an HSI), HDRN minting, HDRN and ICSA staking, selling HSIs to Icosa and redeeming WAATSA NFTs.
Risk: The auctions page is effectively broken because its data source is down. It offers unlimited approvals and approval of all your NFTs to the ICSA contract — prefer approvals per transaction.
-
PulseX app
app.pulsex.com
Official PulseX appPulseChain
Swaps, PLS ↔ WPLS wrapping, liquidity on PulseX v1, v2 and the eDAI/eUSDC/eUSDT stable pool, INC farms (deposit, withdraw, harvest, emergency withdraw) and the buy-and-burn page.
The same version also runs as an IPFS mirror and a self-host build.
Risk: Copycat PLSX and INC tokens exist — add tokens to your wallet by address only. The burn page’s conversion can be triggered only by whitelisted callers.
-
PulseScan — Read and Write contract
scan.pulsechain.com
Official PulseChain appPulseChain
Read contract, Write contract and Write proxy for every verified contract once you connect a wallet. It is the fallback when an app is down, and the only interface for some functions: the Maximus Mystery Box and escrow, MAXI’s own stake end, and the Hedron/Icosa liquidation auctions.
The same version also runs as an IPFS mirror and a self-host build.
Risk: Raw calls with no safety net: wrong units or a mistyped address cannot be undone. There is no Write tab for unverified contracts — eWBTC, “HEX from Ethereum”, the four Diamond Hands reward-distribution contracts and the ProveX escrow (verified on Sourcify only).
-
perpetuals.maximus.cash
perpetuals.maximus.cash
Official Maximus DAO appPulseChainEthereum
Mint or reload BASE, TRIO, LUCKY and DECI with HEX in the reload window, redeem them for HEX after a stake ends, start or end a pool’s HEX stake and mint its HDRN (anyone may trigger these), and stake in the Diamond Hands Club.
Risk: The four Diamond Hands reward-distribution contracts are not verified on PulseScan, Etherscan or Ethereum Blockscout. BASE’s stake on PulseChain ends on HEX day 2,533 (9 November 2026): someone has to end it before the reload window opens.
-
Poly Maximus
poly.maximus.cash
Official Maximus DAO appEthereum
Pools HDRN into POLY, a separate product that is not a listed token.
Risk: No licence; it spends HDRN on a product this site does not review.
-
appHEX
apphex.win
Third partyPulseChainEthereum
HEX stakes and transfers, HDRN minting, INC farm deposits and swaps through the PulseX contracts.
Risk: Closed source. Optional tips to the developer; a fee hook in the code is inactive today but could be switched on in a later release. It promotes the developer’s own wallet extension, which was not reviewed.
-
OpenSea — HEX Stake Instance collection
opensea.io
Third partyEthereum
Trading HSI NFTs on Ethereum.
Risk: Listings show stale details because the project’s metadata service is down — check the stake on-chain before buying an HSI. No official source links a PulseChain marketplace for HSIs.
-
Piteas
app.piteas.io
Third partyPulseChain
DEX aggregator: routes swaps through PulseX and other exchanges via its own router.
Risk: The executor contract is not verified; the router’s owner — a single key — can pause it and change the executor. The fee is built into the quote (about 0.12 % on average, per its docs). Router audited by SolidProof (2023).
-
Coast app (0xCoast)
app.0xcoast.com
Third partyPulseChainEthereum
Account-based app: buying and selling, HEX staking, HDRN minting and its own CST stablecoin.
Risk: Needs an account; its terms describe renting software and private keys, and selling sends your tokens to an address the operator controls (custodial). Closed source.
-
Stake HEX Today
stakehex.today
Third partyEthereumread-only
Shows HEX stakes and HSIs — no transactions.
Risk: Ethereum only; parts of its data sources are gone.
Listing a token is not a recommendation to buy it. Read the trust criteria and the disclaimer.
