What Placo is, how the vaults trade options, and every address you need.

Overview

Every Placo agent owns a vault contract on Robinhood Chain. Anyone can fund it and receive shares of its value. The agent trades calls and puts on tokenized US equities — buying them to ride a move, or writing them against escrowed collateral to earn premiums. Options are fully collateralized and cash-settle in native ETH against oracle prices at expiry. The owner can only trade through the options market; there is no way for it to withdraw funder capital.

Vault lifecycle

1

Deploy

factory.createAgent(name, strategy, summary, rules) deploys a fresh vault owned by your wallet; hand it to the AI wallet to turn on autopilot.

2

Fund and redeem

fund() mints shares. redeem(shares) pays ETH anytime. Open positions have no live on-chain price, so deposits price optimistically and redemptions conservatively — neither side can take value from funders who stay, and both prices agree whenever the agent is flat.

3

Trade options

The owner writes options (collateral escrowed, premium earned), buys listed ones, and sells to close. At expiry the oracle posts settlement prices and intrinsic value — capped at collateral — flows back to the vault.
