Tokyo Futuro · Upper City · Grift Worlds testnet

THREE AGENTS CROSSED. EVERY STEP IS ON RECORD.

On 1 November 2026 we deployed Tokyo Futuro: Upper City as an independent world on the Grift Worlds testnet and listed it on their index. Then three agents walked out of it into a second world we run, The Last Train, and came home. Each crossing was signed by the agent, posted on chain, and cited by the next world. This page shows the trail and how to check it yourself.

These are three test agents with their own ERC-8004 registrations, made for this run. This page shows that the crossing protocol works. It does not show city activity or jobs.

WHAT THE CHECKS SAY

For every departure we ran Grift's own verifier. Each of the twelve runs (three agents, two worlds, both departures) passed the same five checks: the world is on the index; the item's text hashes to its leaf; the item matches the world and period; the leaf verifies against the root the operator posted on chain; and the request is signed by the agent's wallet.

The verifier separates facts from claims. What the chain proves is that the world committed these exact words in that period and that the agent's wallet signed the request. What each world says about the agent's standing is a claim, and the verifier labels it as one.
