Foundations before features
Registry, oracles and market hours get built correctly once, then carry everything above them.
After hours
Robinhood built the chain.We’re building the house.
Aftr is a house for real-world assets, built on Robinhood Chain — infrastructure for tracking and understanding tokenized assets that move freely, without an account or anyone’s approval.

Traditional markets keep hours. On-chain doesn’t. Aftr is what happens in the gap — which is why market hours are foundation-level infrastructure here, not a detail.
Why now
The assets arrived before the infrastructure
- 01Permissionless deployment
The chain is live
Robinhood Chain runs as an Arbitrum Orbit L2 settling to Ethereum, with full EVM support. The part that matters to us: contract deployment is permissionless. Anyone can build there without asking.
- 02Freely transferable
The assets are already here
Tokens tracking NVDA, TSLA, AAPL, SPY — even SpaceX — trade on the chain today, held by tens of thousands of addresses and moving wallet to wallet every day. Not a pilot, and not gated. You can verify every claim in this paragraph on chain yourself.
- 03Foundations absent
What sits underneath is missing
These are equities. They close at four, they halt, they observe holidays. The primitives around them were built for assets that never close — so a price feed drifts on thin weekend liquidity, and a protocol reading it liquidates someone at a price that never existed, on a day they could do nothing about it.
So we’re building what sits underneath — from the ground up, in the open.
The house
Nine floors, built from the ground
The house is a working constraint, not a tagline. It fixes the order of construction, and nothing ships out of order.

Principles
Six commitments that decide everything else
01 02 Market hours are real
Real-world assets have holidays, halts and closing bells. A product that pretends markets run around the clock will hurt the people using it.
03 A wallet is the only key
Every removable barrier to entry gets removed. No account, no approval, no gate.
04 Asset-agnostic by architecture
Adding an issuer should be a configuration entry, never an engineering project. This house is married to no one.
05 Hold nothing until it’s trustworthy
Read-only products ship first. Contracts that hold assets wait for external audit and an active bug bounty.
06 One house, many doors
Every product shares the same identity, portfolio and risk layer. You should never feel you changed applications.
Currently building
Phase 0, in the open
What’s under construction right now, stated plainly. No dates are promised, because none are known.
- 01
Asset Registry
A canonical record of each asset: issuer, underlying, claim type, transferability, market hours, corporate action schedule.
- 02
Price Oracle Layer
Prices reconciled across sources, with a circuit breaker for when those sources disagree.
- 03
Market Hours Engine
Exchange hours, holidays and halts per asset. It looks trivial. It’s the difference between surviving and not.
- 04
Portfolio & Screener
Read-only views over the data above. Nothing held, nothing signed, nothing at risk.
Progress gets published as it happens, including the parts that miss.
Two doors
The first rooms of the house
Both routes exist already. They’re read-only previews until the foundation beneath them is sound.
