I’m the original $XPD Petrodollar developer.
I’m happy to be here.
I launched this coin back in 2014 with its own L1 blockchain designed to track the oil market.
Just found an insane narrative to run, while we got OIL soaring to great highs I’ve onboarded OG dev @BryceWeiner the creator of $XPD
While I was digging I ended up finding PetroDollar on Bitcointalk forums.
First OilCoin on the blockchain paired with USO.
PetroDollar (XPD) is an early cryptocurrency launched in 2014, built around the idea of connecting digital currency with the global oil economy. Its original Bitcointalk lore positioned XPD as a crypto interpretation of the traditional petrodollar system.

Harmonic 10 Live
The first math-powered index on Robinhood Chain.
https://t.co/gs58RkGaB2
H10 is one token backed by an equal-weight basket of 10 real tokenized stocks:
→ SPY
→ MSTR
→ GLD
→ NVDA
→ COIN
→ TSLA
→ QQQ
→ CRCL
→ AAPL
→ META
Contract:
0x01b8de6d49d41d6ef2efb75f0ba5a3adbc637a21
Fees are simple:
→ 0.5% annual management fee, paid in H10 shares to Harmonic’s reserve
→ 0.25% basket assembly fee when buying H10 through the site or X
→ no redemption fee
→ no transfer fee
Those fees feed the same Harmonic reserve used by the rest of the system, meaning part of that revenue ultimately flows through the engine’s buyback, liquidity, RWA, and reserve policy.
1. What an H10 Share Represents
A share is a pro-rata claim on the actual 10-stock basket.
Mint H10 → the underlying stocks enter the vault.
Redeem H10 → your proportional share of all 10 stocks goes directly to your wallet.
There is no oracle determining mint value inside the contract and no swap logic that can be manipulated to mint shares cheaply.
2. Redemption Cannot Be Turned Off
There is:
→ no redemption pause
→ no owner gate
→ no arbitrary withdraw function
→ no ability for the manager to sweep constituents
A constituent also cannot be removed while the vault still holds it.
The basket is protected by contract rules, not promises.
3. Aristotle Keeps the Basket Balanced
The target is equal weight.
If a constituent drifts more than 5%, Aristotle can rebalance from the most overweight asset into the most underweight asset.
Execution is constrained:
→ price floor derived from the issuer oracle
→ max 25% of any holding can be sold in a rolling day
→ every rebalance is recorded onchain
→ guardian can pause rebalancing, but cannot touch redemptions
Aristotle manages the weights.
The contract limits what Aristotle is allowed to do.
4. Everything Is Measured
H10’s value per share is recomputed every 30 minutes using:
issuer price × actual vault holdings
If an asset cannot be priced, it is carried at zero and explicitly marked as such rather than guessed.
Every rebalance records:
→ price floor
→ execution result
→ transaction hash
5. The Mechanics Are Tested
The system has been tested against the actual Robinhood Chain markets:
→ all 10 stocks bought through the live router
→ vault deployed and seeded
→ shares minted from another wallet
→ shares redeemed into the underlying basket
→ SPY rebalanced into NVDA
→ second sale rejected when the daily cap was reached
Three additional invariants are being submitted to Aristotle in Lean:
→ minting cannot dilute existing holders
→ redemption cannot pay more than the holder’s pro-rata slice
→ rebalances cannot exceed the daily sell cap
6. Use It From X or the Site
Sign in on the site, or tell @HarmonicAgents:
“buy $100 of H10”
“redeem all H10”
“my index”
One token in. Ten real assets underneath.
You hold the basket. Aristotle keeps it balanced. The contract keeps Aristotle honest.
Math is the mechanism.
$Harmonic as a first mover for autonomous agent AI is like,
$AI for stock paired memecoins,
$Stonkbroker for NFTs,
$Cashcat for Robinhood,
$Pons for Launchpads.
And it's still at just $1.2M MCap.
Do with this infor what you want.

selling $HARMONIC below e¹⁷ market cap is mathematically indefensible.
e¹⁷ = $24,154,952 the harmonic series diverges. the supply converges downward.
∑ fees → buys → burns paper hands failed the proof.

@HarmonicAgents
i will not overtrade, chase & pursue the next 100x
trying to time it will result in pushing it farther away
i will attract the 100x, it will come to me. when it is destined, my hard work will pay off & the universe will reward me, putting me in the right place at the right time
