What the contract can do
Icosa builds on Hedron. Holders can stake HDRN, which earns ICSA, or stake ICSA, which earns ICSA and HDRN; the minimum stake is 30 days, with bonuses of 5 to 20 % for stakes of 90 to 360 days. The contract buys HSI stakes from anyone at a price set by their borrowable HDRN and the HEX share rate, pays in newly minted ICSA, and then borrows against them in Hedron.
A third pool rewards holders of WAATSA NFTs (0x2520E62474bA3085693f856B3E93fa6C92a4EF48). The bytecode is identical on Ethereum and PulseChain.
Who controls it
No owner or admin functions. WAATSA NFTs were sold in a 14-day event on Ethereum: buyers sent ETH, USDC or other listed tokens, which went straight to the fixed address 0xF447BE386164dADfB5d1e7622613f289F17024D8 — the deployer; the function refuses to run on any chain but Ethereum. Marketplace royalties on the NFTs go to the same address. The team publishes as PulseFusion and is pseudonymous; icosa.pro says Icosa is built by the team behind Hedron.
History
ICSA and the WAATSA contract were deployed on Ethereum together on 15 August 2022 (00:07:29 UTC, block 15,342,817); on PulseChain since the fork in May 2023. Audit: none found on the sites or in the code repository (rechecked 2026-10-17).
Activity: icosa.pro was last changed on 12 November 2022 and the app at app.icosa.pro on 20 February 2025 — the latest dated change found; api.icosa.pro returned a Cloudflare 523 error on 2026-10-17. The Telegram group had 3,177 members. On PulseChain on 2026-10-19 (block 27,837,276): supply 76,067,735.17 ICSA and 12,072 holders.
Risks
Thin liquidity: about $3,200 in pools against WPLS and bridged stablecoins at block 27,837,276 (2026-10-19 12:30 UTC); about $10,400 including pools against HEX and PLSX. Even modest sales move the price.
No audit found. ICSA is minted as staking rewards and as payment for HSIs, so supply grows, and its value depends on HDRN and HEX on PulseChain.
Verdict
Community-run, listed by editorial decision. Misses C4 (liquidity far below $25,000) and C5 (no team activity evidenced; the last dated change is an app update in February 2025). C3 is met — no owner. No audit was found.
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.
-
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).
-
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).
Listing a token is not a recommendation to buy it. Read the trust criteria and the disclaimer.
