Rentday documentation

How the vault works, where each figure comes from, and how to check it yourself.

What Rentday is

Rentday is a vault on Robinhood Chain. You deposit USDG and receive vRENT, an ERC-4626 share of the vault. An operating company owns a small set of let apartments in US cities. Each month it pays the buildings' bills out of the rent it collects and transfers what is left to the vault as USDG.

That transfer raises the price of every vRENT. Nothing is paid into your wallet in the meantime: the gain sits in the share price, and you take it when you cash out, in one transaction with no exit fee. Appraisals and price feeds play no part. The price rises when USDG reaches the vault without new vRENT being issued, which under normal operation happens once a month, on rent day.

On the 1st of each month the operator publishes the Roll: a CSV file with one line per apartment (paid, late or vacant), every cost, and the resulting price. The file's SHA-256 hash is written on chain, so you can confirm that the file you are reading is the one that was committed. The vault and the Roll registry are live on Robinhood Chain; their addresses are on Chain and addresses. Until the first real Roll publishes, the site shows six sample Rolls built from illustrative data and labels each one as a sample.

Where to start

If you are new, read the first three pages in order. The rest are reference.

  • How it works: the monthly loop from rent collection to a higher share price, and what you own.
  • Share price: how the price is calculated, what moves it, and why a bad month stalls it without lowering it.
  • Deposit and cash out: approvals, the minimum, the cap and pause, and what the owner key can and cannot do.
  • Fees: the seven cost lines, their rates, and the rules for where fees come from.
  • Risks: what can go wrong, stated as plainly as what goes right.
  • Reading a Roll: each section of the monthly file and the sums you can check by hand.
  • Verifying a Roll: how to match a Roll file to the hash on chain, and what a match proves.
  • Roll format: the exact byte layout of the file that gets hashed.
  • The $RENT token: the community token and the 1% trading fee it sends to the vault.
  • Chain and addresses: network settings, contract addresses and decimals.
  • Contracts: RentdayVault and RollRegistry, function by function.
  • Operator guide: the monthly close as a runbook, plus the one-time launch steps.
  • Run locally: build and serve the site, run the tests, and a map of the source files.
  • Security: what the tests cover, the checks the site makes, and the known limitations.
  • Disclosures: what vRENT is, what is not guaranteed, and the terms still to be published.
