Thematica groups the 27 Robinhood Stock Tokens into themes, shows how each theme did against the S&P 500, and buys a whole theme for USDG in one transaction. It has no contract of its own and holds nothing: the stocks go to your wallet.

The themes

Fixed lists, equal weight. A stock can sit in more than one theme.

Returns

For each member, the price move over the last 5, 21, 63, 126 and 252 sessions from daily closes, with today's price taken live from Chainlink. A theme's return is the plain average of its members. The S&P 500 line is the SPY Stock Token measured the same way.

Daily closes come from Yahoo Finance through the site's endpoint, cached for six hours. A stock with too short a history for a window shows a dash and is left out of that window's average.

Your own basket

Pick up to eight Stock Tokens and give each a relative weight. The panel shows the basket's return by period against the S&P 500 and what each member did.

Buying

• One USDG approval to Uniswap's SwapRouter02, then one multicall with an exactInput per member.
• Every leg has a minimum out set from Chainlink: 0.5%, 1% (default) or 2% below the fair amount. If one leg can't meet it, the whole transaction reverts.
• COIN, MSTR and SPY route USDG to WETH to the stock; the rest trade against USDG directly.
• You pay pool fees and gas. Thematica takes nothing. There is no rebalancing: the stocks are yours to hold or sell.

The token

$THMA launches on pons. The themes, the builder and buying work the same with or without it.

Limits

• Past returns are history, not a forecast. Not financial advice.
• Thin pools can be far from Chainlink; then the buy waits for you to widen the limit or try later.
• Price history is for the listed stock; the on-chain token tracks it through its pool.
