An Ether reserve,
built to compound.

Sapheth accumulates ETH, puts it to work through staking, and grows the amount of Ether behind each share — cleanly, without excessive leverage.

01 — The thesis

Finance is no longer digitizing.
It settles on-chain.

Asset tokenization, the programmable dollar, autonomous agents: three distinct currents converging on a single settlement layer. And that layer, today, is Ethereum.

~65 %
of tokenized real-world assets are issued on Ethereum
>50 %
of the global stablecoin supply circulates on Ethereum
~30,000 B$
in stablecoin volume settled on Ethereum in 2025

2030 projection — McKinsey, BCG, Citi and Standard Chartered estimate 2,000 to 16,000 B$ of tokenized assets by 2030 ; Ethereum is its center of gravity today.

The tokenization of real-world assets

Bonds, funds and real estate are becoming on-chain securities. Major institutions project between 2,000 and 16,000 B$ of tokenized assets by 2030 — and Ethereum is its center of gravity.

The programmable dollar

Stablecoins already settle, in annual flow, more than Visa and Mastercard combined. More than half of the global supply circulates on Ethereum, now governed by federal law.

The economy of machines

AI agents pay, negotiate and coordinate on-chain, in programmable money. Ethereum positions itself explicitly as the settlement layer of this nascent economy.

BlackRock, JPMorgan, Franklin Templeton, Siemens: the largest financial institutions are already building on these rails — not out of ideological conviction, but because this is where everything already settles.

02 — The project

An Ether treasury,
listed and productive.

Sapheth is an investment vehicle that holds a reserve of ETH, entrusts it to institutional custodians, and puts it to work through staking — the native income the Ethereum network pays to those who secure it.

Ξ

The reserve

Ether, and nothing else. Held with qualified custodians, segregated and insured. The withdrawal keys never leave custody — only validation is delegated to regulated operators.

Staking

The reserve produces a native yield of about 2.8 % per year, paid by the protocol itself. A rent independent of the markets, which funds the structure without ever selling the asset.

ETH per share

The measure that matters. The goal is not to multiply the shares, but to increase the amount of Ether behind each of them — cycle after cycle, without diluting shareholders.

03 — The mechanics

A flywheel that accumulates ETH in every share.

The network pays a rent (staking). That rent pays the coupons on the financing. The financing buys additional ETH. And each share contains a little more than before — without a single new share being created.

And the shareholder, meanwhile ?

Nothing. They don't stake, don't reinvest, don't click anywhere. The loop turns for them.

  • The number of shares doesn't change. The loop is funded by income from the network and from coupon-bearing securities — never by creating new shares.
  • The content of each share grows. The ETH acquired on each turn is spread across the same shares: yesterday's share holds more Ether today.
  • The loop is conditional. It only turns if the prudence rules are met — otherwise it stops, and the reserve waits.

Illustrative counter — it shows the principle, not a yield.

04 — The safeguards

Built to last,
not to run away.

The sector has shown what excess leverage leads to. Sapheth takes the opposite path : a deliberately de-leveraged structure, where each tier is bounded by a simple, verifiable rule.

De-leveraged by design

The ETH reserve is worth four to four and a half times the coupon-bearing securities issued (target ratio 4–4.5×). Leverage stays moderate (~1.3×) and cannot run away: it's a rule of structure, not a promise.

Over-covered coupons

Staking income covers the coupons to be served about one and a half times over. The yield could fall by a third without putting the coverage in default.

Never a forced sale

In a bear market, the reserve stays intact for the rebound. No margin call, no liquidation: staking keeps paying while the cycle passes.

Institutional custody

Qualified custodians, regulated and diversified staking operators, segregated and insured assets. Real, identified counterparties — not anonymous code.
