TOMB.ETH is a deflationary bonding-curve protocol deployed on Ethereum mainnet. Users do not buy or sell tokens: they bury ETH and exhume it. Price is determined entirely by a quadratic bonding curve, supply is hard-capped at 999,999 souls, and every transaction routes 1% to a permissionless reward pool called The Altar. A mandatory time-lock enforces patience: positions held fewer than 300 blocks incur a linearly decreasing penalty, which is burned—not redistributed—deepening the crypt on every impatient exit.
All protocol logic is immutably deployed on Ethereum mainnet. No proxy, no admin key, no upgrade path.
TOMB.ETH uses a quadratic bonding curve. The instantaneous price of one TOMB token at supply level S is:
The integral of the curve from supply S₀ to S₁ defines the ETH required to mint (or returned on burn) for that range:
| Supply (souls buried) | Price per TOMB | % of cap reached |
|---|---|---|
| 1 | 0.0000000000041 Ξ | 0.0001% |
| 100,000 | 0.00001000 Ξ | 10.0% |
| 350,000 | 0.00041 Ξ | 35.0% |
| 500,000 | 0.00103 Ξ | 50.0% |
| 700,000 | 0.00201 Ξ | 70.0% |
| 900,000 | 0.00333 Ξ | 90.0% |
| 999,999 | → ∞ (asymptotic) | 99.9999% |
The curve is monotonically increasing and unbounded in the limit. Deeper burial always raises the price of the next soul. Early participants benefit from lower entry cost; late entrants fund the earlier graves.
To acquire TOMB, a user buries ETH by calling the contract's bury() function.
The contract computes, via numerical integration over the bonding curve, how many TOMB tokens
the submitted ETH purchases at current supply.
| Component | Rate | Destination |
|---|---|---|
| ETH to curve reserve | 99% | Protocol ETH pool (the crypt) |
| Offering to The Altar | 1% | Altar rewards contract |
Once buried, the position is immediately time-locked for 300 Ethereum blocks (~1 hour at 12s/block). The TOMB balance is fully transferable; only the penalty-free exhumation requires the lock to expire.
To exit, a user exhumes TOMB by calling exhume(amount). The contract burns
the submitted TOMB and returns ETH calculated from the integral of the bonding curve at the
current supply, minus any applicable time-lock penalty and the 1% altar offering.
| Component | Condition | Rate | Destination |
|---|---|---|---|
| Altar offering | Always | 1% | Altar contract |
| Time-lock penalty | Block < 300 | 6 – 30% | Burned |
| Net ETH returned | — | 69 – 99% | Caller wallet |
The penalty is burned from the reserve—it reduces the total ETH backing the curve and therefore cannot be claimed by any party. This creates a deflationary pressure on the ETH/TOMB ratio for all remaining holders with every impatient exit.
Each bury() call records the block number at time of burial. When
exhume() is called, the elapsed blocks are computed and a penalty is
applied according to the following schedule:
| Blocks elapsed since burial | Approx. wall time | Penalty |
|---|---|---|
| 0 – 100 | ~0–20 min | 30% |
| 100 – 200 | ~20–40 min | 18% |
| 200 – 300 | ~40–60 min | 6% |
| 300+ | ~1h+ | 0% — free exhumation |
Penalty decreases linearly within each band. At exactly block 150 the penalty is approximately 12%. At block 250 approximately 3%. The transition at block 300 drops cleanly to 0%.
The Altar (0xa1b2c3d4e5f6789012345678901234567890abcd) is a separate,
immutable contract. It accumulates the 1% offering from every burial and
exhumation, permanently and without exception.
| Event | Contribution |
|---|---|
| Each burial (bury()) | 1% of ETH deposited |
| Each exhumation (exhume()) | 1% of gross ETH returned |
The Altar distributes accumulated ETH proportionally to TOMB holders who have staked their tokens into the Altar contract. Staking is optional; unstaked TOMB can still be exhumed at any time. The Altar rate (ETH per staked TOMB) compounds continuously as new offerings flow in.
The hard cap is 999,999 TOMB. The contract will revert any burial that would push supply past this number. The cap is the cursed number: one less than a million, unreachable by design.
| Parameter | Value |
|---|---|
| Maximum supply | 999,999 TOMB |
| Current supply (at launch) | 349,812 TOMB |
| Remaining souls | 650,187 TOMB |
| Curve fill | 35.0% |
| ETH in reserve | 143.44 Ξ |
| ETH in Altar pool | 1.434 Ξ |
As supply approaches 999,999 the quadratic curve drives price toward infinity. The final souls will never be affordable. That is the point. No whale can complete the burial. No one owns the last grave.

While the protocol is immutable and contains no admin keys, undiscovered vulnerabilities may exist in the bonding curve arithmetic, the time-lock logic, or the Altar distribution mechanism. No audit guarantee is provided.
All liquidity is internal to the bonding curve. There is no external AMM pool. Large exhumations will move price downward along the curve. In low-supply periods, slippage for large positions can be significant.
Penalties up to 30% apply to early exhumation and are permanently burned. There is no grace period, no override, and no appeal. The crypt does not negotiate.
TOMB.ETH may be classified as a security or financial instrument in certain jurisdictions. Users are solely responsible for compliance with applicable laws.
As supply approaches 999,999 the price per soul approaches infinity on the curve. No mechanism exists to expand the cap. Buyers near the ceiling face extreme price impact and may be unable to find counter-parties willing to absorb an exhumation at curve price.
