The live vault — Arca Frontier

Contract	Address

The basket — real Robinhood stock tokens

Five names, picked by on-chain liquidity checks (two-way Uniswap v4 depth against USDG within ~1% of oracle) so the agent can rebalance every leg permissionlessly.

The proven loop — rehearsal receipts (testnet)

Ahead of mainnet, the same contract suite ran the full loop on RHC testnet (chain 46630) with real testnet stock tokens. The receipts stay public:

Operation	What happened	Transaction
Mint	deposited the basket → minted 1 index token, fully backed	0x4f8a9a…2f90df ↗
Rebalance	agent rotated weights through its policy gate; fully backed before and after	0xa02e4d…e4debc ↗
Redeem	burned 0.5 index token → all stocks returned in-kind, one tx	0xb5efff…0ba98f ↗

Verify it yourself

With Foundry's cast against any RHC mainnet RPC:

# is one token still fully backed by the basket?
cast call 0x04f4F5b8572d0b925557BE9F42C92B9Edce9F628 "isFullyBacked()(bool)" --rpc-url https://rpc.mainnet.chain.robinhood.com

# portfolio value (USD, 18 decimals) and supply
cast call 0x04f4F5b8572d0b925557BE9F42C92B9Edce9F628 "nav()(uint256)"         --rpc-url https://rpc.mainnet.chain.robinhood.com
cast call 0x04f4F5b8572d0b925557BE9F42C92B9Edce9F628 "totalSupply()(uint256)" --rpc-url https://rpc.mainnet.chain.robinhood.com

# what the vault actually holds (e.g. NVDA)
cast call 0xd0601CE157Db5bdC3162BbaC2a2C8aF5320D9EEC \
  "balanceOf(address)(uint256)" 0x04f4F5b8572d0b925557BE9F42C92B9Edce9F628 \
