General plan / Construction
What is built, what is drawn.
No inflated claims. This sheet separates the yard that exists from the yard on paper — and says which is which.

Audited — not yet
Mainnet — pending
Phase I — the vault
Single vault contract: four levers, owner controls, on-chain policy revisions. Foundry test suite running. Deploy target: Robinhood Chain mainnet.
In testPhase II — the table
Read-only tools: this site's vault readout, the dry-run rule simulator. Ships with the contract — the table reads real state or shows nothing.
Drawn · ships with Phase IPhase III — owner controls in-browser
Seal, unseal and cancel from your own wallet on the table page. Self-custodied signatures only — keys never touch this server, because there is no server holding keys.
Drawn · ships with Phase IPhase IV — open source
Contract and SDK published under MIT. Anyone can deploy their own yard; every yard is readable on the table.
PendingAudit
No third-party audit yet. When one happens, this line changes — until then: do not route real funds through anything claiming to be RAILS.
Not yet auditedQuestions
Is RAILS live?
Not for real funds. The vault contract is in test; the $RAILS launch is pending via PONS. The table goes live with the contract — until then it shows awaiting states, never sample data dressed as real.
Do I need a wallet to use this site?
Reading never needs one. The table, the dry-run simulator, every sheet — all readable without connecting anything. A wallet is only asked for when an owner signs a real action (Phase III).
What can't the four levers stop?
Honest edges: a drawn route used within its limits still executes — the levers bound the agent, they do not judge strategy. Axle buckets are fixed clock windows, so a boundary can admit about twice a ceiling briefly. Queued loop calls do not expire on their own. And the owner key is the root of trust: whoever holds it can redraw everything.
What does it cost?
Deploying a yard costs standard Robinhood Chain gas. The contract is MIT-licensed with no protocol fee — the code is the product; $RAILS is the token of this project, not a toll on your vault.
Why "rails"?
Because a train does not choose its path — the interlocking does, physically, in advance. See the name →
Is this affiliated with Robinhood?
No. An independent work, not affiliated with Robinhood or any launch platform. Built on the public chain, that is all.
