Isolate
Each run is a sealed session with a throwaway wallet, an in-memory chain fork and no account. Close the tab and it's gone.

Agents need a safe place to be wrong
A2I2 Sandbox is an isolated lab for AI agent experiments on Robinhood Chain. Run strategies against a simulated fork, enforce guardrails before any transaction, and keep every byte of your data on your machine.
What the sandbox does
Four walls around every experiment
Agents get room to act, but they can't reach real funds, real keys or your data.
Simulate
Synthetic tokenized-stock and ETH markets on seeded price paths, so any experiment replays block for block.
Guard
Every intent passes the policy before it executes: trade caps, allowlists, cooldowns, concentration limits and a drawdown kill switch.
Observe
A full decision trace shows what the agent wanted, what the policy allowed, what executed and what it cost in gas.
Privacy model
Nothing leaves the box unless you send it
The sandbox makes one kind of network request: a read of the testnet head, and only when you click for it. Everything else, including agent traffic, is simulated, intercepted and logged in a ledger you can inspect.
- No accounts
- Nothing to sign up for, nothing tied to you.
- No server
- The simulation runs entirely in your browser tab.
- Egress intercepted
- Agent network calls are caught and checked. None of them are actually sent.
- Redacted by default
- Wallet addresses and strategy state are stripped from traces and payloads.
Sealed sessionHow it works
Three steps, one tab
- 01
Pick an agent
DCA, momentum, mean reversion, a rebalancer, or a red-team agent that tries to break the rules.
- 02
Set the guardrails
Choose what the agent may touch, how much it can risk, and where its data may go.
- 03
Run, step, replay
Watch decisions at block speed, pause on any tick, and replay the same seed to compare policies.
