HEXROCK
Certified by Guinness. Paid for in crypto.
The largest cut diamond on Earth. 555.55 carats, 55 facets, bought at Sotheby’s in cryptocurrency by the man who built HEX. He was right about that too.
The Lore
Six years of ridicule from people who never opened the contract. Six years of HEX doing exactly what it said it would, on schedule, without a single pause. The critics moved on to the next thing. The code is still running.
Richard Heart wrote the first certificate of deposit into a blockchain and shipped it on 2 December 2019. Commit your coins for a fixed term, earn from a fixed issuance schedule. Stake longer or larger and you earn more. End early and your penalty goes to everyone who stayed. No bank sets the rate, and nobody gets a better deal than you do.
Read the deployed bytecode. No owner. No mint function. No pause switch. No proxy to upgrade through. No company, no custodian, nobody to beg for your coins back. He gave up every power over it on day one, which is the one thing the people copying him still refuse to do.
Called a scam every week for four years, always by people describing the marketing and never the code. In 2023 the SEC sued over HEX, PulseChain and PulseX. In February 2025 a federal judge threw the case out for lack of jurisdiction, and that April the SEC walked away from it entirely. HEX did not pause for a single block.
Then he bought The Enigma: 555.55 carats, 55 facets, the largest cut diamond on Earth by Guinness record, taken at Sotheby’s in February 2022 for $4.3 million paid in cryptocurrency, and renamed The HEX.com Diamond. Nobody else in this industry has done anything close. HEXROCK is that rock, on PulseChain and Solana.

Official Contract Addresses
HEXROCK on PulseChain lives next to HEX and is the one that will earn HEX. HEXROCK on Solana is the Pay RH edition, whose creator fees go to Richard Heart. They share a name and nothing else, with separate supplies and no bridge between them. Verify the address character by character before you buy. These two are the only HEXROCK contracts; anything else is not ours.
Pay RH
HEXROCK on Solana, launched on pump.fun through UsePaid. The creator fees from every trade go to Richard Heart (@RichardHeartWin on X). The man who gave the world HEX and PulseChain for free gets something back.
Richard Heart is not involved in, has not endorsed, and has not asked for this. Whether he ever claims the fees is entirely up to him. This is a separate token from HEXROCK on PulseChain, with its own supply and no bridge between them. Verify the address in the contracts section before you buy; anything else calling itself HEXROCK on Solana is not ours.
Stake HEXROCK on PulseChain. Earn real HEX. Not a wrapper, not an IOU, not a points program. The actual HEX contract that has been running since day one.
Not live, and nothing here is a commitment to a rate, a date, or a return of any kind. It depends on HEXROCK graduating off the bonding curve into a PulseX pool first, because that pool is what produces the fees. When it ships, the vault address will be published on this page.
