How a smart contract works

A smart contract is a program deployed to a blockchain. It can hold tokens, including stablecoins, and it follows its code exactly: when a function is called and the stated conditions are met, it executes, and the result is recorded for everyone to see.

Two properties make it useful and limit it.

It is deterministic and transparent. Everyone can see the rules and the result, and nobody can quietly change the outcome of a completed step.

It only knows what is onchain. A contract cannot see whether an inspection passed, a mortgage was approved, or a tenant moved out. Those facts have to be supplied by someone, such as a party to the deal, an agent, or an external data service known as an oracle, and the contract is only as reliable as that input.

So the useful question for any real estate use is which part of the process is a rule about money or records that can be automated, and which part depends on facts, judgement, or the legal system.

Five examples

1. Escrowed deposit. A buyer places an earnest money deposit, in a stablecoin, into a contract. The contract releases it to the seller when both parties, or a designated escrow agent, confirm closing conditions are met, or returns it to the buyer if a contingency fails by a deadline. The contract automates holding and releasing funds; the agent or parties still decide whether conditions were met.

2. Rent distribution to token holders. A property held by an entity whose shares are tokens collects rent. The manager deposits net income into a contract, which distributes it to current token holders in proportion to their holdings. This removes manual payment runs and ensures distributions match the ownership record at a set time.

3. Transfer restrictions on property tokens. A permissioned token only allows transfers to wallets verified as eligible investors and blocks transfers during lock-up periods. This keeps a tokenized offering consistent with the securities rules it was issued under.

4. Recurring lease payments. A tenant authorises a contract to collect a fixed stablecoin amount on a schedule, with late fees applied by rule and a record of every payment. Eviction, repairs, and disputes remain governed by the lease and local tenancy law.

5. Construction milestone payments. Funds for a project sit in a contract and are released in stages when an inspector or project manager confirms a milestone. Everyone can see what has been paid and what remains.

What smart contracts do not replace

The legal agreement. A purchase contract, lease, or operating agreement defines rights and remedies. The code should implement that agreement, and the agreement should say what happens if the code fails or produces the wrong result.

The land registry. In most jurisdictions, legal title to land is recorded in a government registry. A token or contract can represent an interest in an entity or a claim, but it does not transfer title to the land itself unless the jurisdiction's law recognises that record. Several governments have piloted blockchain-based registries, which is different from a private contract claiming to transfer title.

Due diligence. Title searches, inspections, surveys, and financing approvals still happen off-chain.

Dispute resolution. If a party claims a condition was confirmed wrongly, courts or arbitrators decide, and the contract needs a lawful mechanism, such as an authorised administrator, to follow their decision.

Security. Bugs in contract code can lock or lose funds. Audited, simple contracts with limited scope are far safer than complex custom ones.
