Mortgage markets, onchain

Mortgage Yield,
Onchain.

StableYield turns every trade on Pons into a reserve of US mortgage credit — and pays the yield of that reserve back to the people who hold it.

Hold mortgage yield
in seconds.

One token, bought on Pons like any other. Every trade feeds a reserve; the reserve holds US mortgage credit on Robinhood Chain; the yield comes back to holders. No account, no minimum, no intermediary between you and the chain.

Protocol

Real estate debt,
made liquid.

Three steps, all of them on chain. The fee is Pons' own creator-fee mechanism; the reserve is a wallet you can read; the mandate is written here and nowhere else.

01

Buy

$SYLD trades on a Pons bonding curve, quoted in ETH, then on Uniswap v4 after graduation. Every swap carries Pons' 1% curve fee and a 2% creator fee.

02

Reserve

The creator fee accrues in Pons' escrow to one address: the Reserve. Its mandate is tokenized US mortgage credit on Robinhood Chain — agency MBS first. Until such an asset trades with real depth, the ETH is held, not spent.

03

Earn

What the reserve earns — coupons, distributions, NAV — is paid to $SYLD holders pro rata. Distributions start the day the reserve holds a yielding asset, and not before.

Why mortgages

The largest credit market in the world is not on chain.

Mortgage credit is senior, collateralised by real property, and priced every week. Agency MBS hold roughly a quarter of the US aggregate bond market. None of it trades on Robinhood Chain today — the tokenized bond funds on the chain are deployed, and empty.

StableYield is built for the day that changes: the reserve is funded now, the mandate is public now, and the page below reads those funds every minute so you see the market appear before we say it did.

Rule

The reserve buys the highest tier that trades with real depth — more than fifty holders and a thousand transfers, read from the explorer, not announced. Until then it holds ETH. It never holds $SYLD.

Token

$SYLD is launched through Pons' public factory like every other token on the chain: fixed supply, nothing held back, the curve locked. The only thing that makes it StableYield is where its creator fee goes.

Where a trade goes
SWAPA buy or sell of $SYLD on the Pons curve, later on Uniswap v4.
1% + 2%1% is Pons' curve fee. 2% is the creator fee, set at launch, a tax on top — not a share.
ESCROWPons' fee escrow credits the 2% to the Reserve address, in ETH. Pulled by claim(), never pushed.
RESERVEHeld as ETH; converted into mortgage credit the day it trades on the chain.
HOLDERSReserve income is paid to $SYLD holders pro rata. Nothing is paid before it is earned.
Supply

1,000,000,000

Fixed by the factory's config. No mint function, no team allocation, no presale.

Graduation

4.2 ETH

The curve graduates into a Uniswap v4 pool built by Pons, liquidity locked. The 2% then continues as a hook fee.
