Pure-Equity Build-to-Rent
with 2/3 Sale Vote

HBTRE1 is a fractional share of Brazilian Build-to-Rent. No dividends during construction. Rent pro-rata once operational. Sale of the underlying requires an on-chain 2/3 supermajority — the Governor role is irreversibly locked so even the admin Safe can't bypass it.

Equity puro, voto puro — cada holder com sua parte, cada venda com seu voto.

How it works
Rent only when operating. Sale only by vote.
HBTRE1 strips the construction-phase yield entirely. Holders wait for habite-se, then receive rent pro-rata via snapshot epochs. The exit is decided on-chain by holders, not the operator.
Step 01
Subscribe
Buy HBTRE1
Subscribe at par from the Lobie-Haus-Btr Safe treasury. Reg S Cat 3. No U.S. persons in primary. Free transfers after.
Step 02
Wait
Construction Phase
Zero dividends while the building is constructed. Tokens remain freely transferable. depositRent() reverts. No fixed-income framing, no SPE cash obligation.
Step 03
Earn
Collect Rent
After habite-se, Lobie Safe deposits monthly BRLE rent. Snapshot epochs freeze your balance at that block; call claim(epochIds[]) to pull your pro-rata share.
Step 04
Vote
Decide on Sale
Any holder may propose a sale. Vote passes only at ≥2/3 of votes cast (50% quorum). Timelock delay. Winners claim-and-burn for pro-rata proceeds.
Lifecycle
Four phases. One-way. Enforced on-chain.
The contract enforces the phase machine strictly: rent can only flow during OPERATIONAL, sale can only execute via GOVERNOR_ROLE (the Timelock, after a 2/3 vote). No upgrades. No admin override.
Phase 0
Offering
Primary distribution
Tokens distributed to initial holders. Free transfers. No rent flows. Operator advances on funds-closed milestone.
Phase 1
Construction
Zero dividends
Building under construction. depositRent() reverts with WrongPhase. Tokens freely transferable. Operator advances on habite-se.
Phase 2
Operational
Rent pro-rata
Lobie Safe deposits monthly rent. Each deposit creates a snapshot epoch. Holders claim pro-rata by epochId. Transfers remain free.
Phase 3
Sold
Claim-and-burn
After 2/3 vote + Timelock + execution. totalSupplyAtSale is frozen. Holders burn tokens for pro-rata share of proceeds. Terminal state.
Governance
The 2/3 sale vote, end to end
Standard OpenZeppelin Governor with one critical override: proposals whose calldata targets initiateSale(uint256) on the Share require 2/3 supermajority. Every other proposal (pause, parameter change) passes at simple majority. Detection happens at propose-time and is publicly flagged via isSaleProposal[id].
01 · Deposit
Buyer/operator transfers BRLE sale proceeds to the Share contract via depositSaleProceeds(amount). A public event confirms funds are on-hand before voters vote.
02 · Propose
Any holder with ≥ 1% of supply calls governor.propose(share, 0, initiateSale(proceeds), description). Governor inspects calldata and flags isSaleProposal[id] = true.
03 · Vote
1-day voting delay, 7-day voting period. Quorum 50% of supply must cast. Then: forVotes × 3 ≥ (for + against) × 2 — i.e., ≥2/3 of decisive votes must be FOR.
04 · Queue
If succeeded, anyone calls governor.queue(). Timelock holds the transaction for 2 days, giving the ecosystem time to react before execution.
05 · Execute
After timelock delay, anyone calls governor.execute(). Timelock calls share.initiateSale() → phase moves to SOLD, totalSupplyAtSale freezes.
06 · Claim & Burn
Each holder calls claimSaleProceeds() — tokens burn, BRLE transfers out at pro-rata of the frozen supply. Idempotent, non-reentrant, pull-model.
Variant comparison
What's different from the Hybrid variant
Both variants tokenize Brazilian BTR on Base. The equity variant drops two features the hybrid has, and adds one the hybrid doesn't.
Hybrid · SALRIO
Debt + Equity
  • CDI proxy yield during construction
  • Batog 2018 dividend math
  • Operator Safe decides sale
  • Exclusion list for DEX pools
Equity · HBTRE1 (this page)
Pure Equity
  • No construction dividends
  • Snapshot epochs (ERC-20 Votes) — no Batog
  • 2/3 on-chain vote decides sale
  • Governor role irreversibly locked
Features
Minimal surface area. Maximum immutability.
Every feature exists to tighten the guarantee or reduce attack surface. No construction-yield plumbing, no exclusion list, no dividend-per-share counters. The contract does less — on purpose.
Phase Gate
Rent only during OPERATIONAL
The phase enum is enforced strictly: depositRent reverts in OFFERING, CONSTRUCTION, and SOLD. Pre-operational cash obligations simply cannot be created on the SPE. Cleaner legal.
Snapshot Epochs
Historical-balance pro-rata
Each depositRent pushes an epoch snapshotted at the prior block. Claim reads getPastVotes(holder, block) × amount / getPastTotalSupply(block). No Batog counters, no exclusion list, no settle-on-transfer.
2/3 Override
Sale-specific supermajority
Governor._voteSucceeded detects sale proposals by calldata selector. Applies 2/3 threshold on sale, simple majority everywhere else. Abstain votes count for quorum, not for the ratio.
Role Lock
Irreversible handoff
After granting GOVERNOR_ROLE to Timelock, the Safe calls lockGovernorRole(). The role's admin becomes itself — even DEFAULT_ADMIN can no longer grant or revoke it. The 2/3 vote is the only path.
Delegation Off
Auto-self-delegation
Explicit delegate() reverts. Balances auto-self-delegate on receive, so historical voting power always equals historical balance. Rent math and governance math align perfectly by construction.
Claim-and-Burn
Terminal redemption
After sale, holders call claimSaleProceeds() — tokens burn, BRLE transfers out. Frozen totalSupplyAtSale is the pro-rata divisor. Clean finality; no phantom supply on a settled asset.
