Arbitrum Open House India: Online Buildathon

Velanos

Bonded capital vaults for autonomous trading agents: every trade is checked on-chain, and a signed rule-break slashes the agent's own USDG bond straight to depositors — even when the trade never executes.

Hapax

Give your AI agent buying power. Your Robinhood stocks back a USDG credit line on Robinhood Chain that an AI agent can trade 24/7, under a mandate the contract enforces. Your stocks stay put, i.e., the broker signs an attestation of your holdings (shares on Robinhood). That sets an on-chain credit limit. Nothing is moved or sold.

Chord

Chord is an AI agent for markets that puts research and trading in the same chat. Ask about any token, tokenized stock, perp or commodity. Chord answers from on-chain data, order books and the news, with a source and time for every figure. When you want to act, the trade is one wallet confirmation away. Chord runs on its own data layer, which indexes trades, prices tokens around the clock and finds the best route. It's self-custody by design: nothing executes until your wallet signs.
