Circuit PAPER TRADING

Fake money on real markets

Circuit PERMITS

Your agent never touches the keys

One passkey signature starts an agent for 30 days. Your wallet stays self-custodial, with its key in a hardware enclave. Stopping the agent deletes the permit.

What people said on X

i’m not a perps guy, so i had zero clue how to farm papertrade. but thanks to @0xfoobar I imported my wallet on launch night, went to bed, and the robots did everything for me. legend

gr3g · @gr3gor14n

read up on circuit, went on there, and had an agent guide me through depositing USDC, bridging to hypercore, and opening a delta neutral strategy to farm $PAPER. it did this all on its own btw

Foobar has been building a very cool system for onchain agentic trading, if you’ve wondered how AI can make you money onchain, or at least let you lose it in new unfathomable ways, it’s worth checking out.
