Tendies Cup is a skill-based trading league where nobody risks capital. Every entrant gets a virtual $100,000 and trades real assets at live Chainlink prices. Best book at the close takes a posted prize, paid on-chain. Nothing inside a cup is a real position: the only real transactions are the entry and the payout. Every number on this page is read live from our own public endpoints and from the chain, so you can check each one yourself.
Every entry burn and every fill in a cup, as JSON or CSV: wallet, name, side, quantity, the mark, and the round id or block it was read at. Call the feed with that round id and you get the same number. Anyone can recompute the whole leaderboard from this file.
Open the audit feedOne public wallet funds every posted pot and every payout leaves it. Check the balance before a cup opens and the transfers after it settles. Our results page reads those transfers from the chain, so a winner shows as paid without us marking anything.
Prize wallet on BlockscoutTap any row to see that entrant's open positions with weights and returns, or that they are sitting in cash. Untraded books are ranked but never paid. Nothing is hidden until settlement.
Live leaderboardSettled cups keep their final table forever, each winner linked to the transaction that paid them. Marks are frozen at the close, so a finished book never moves again.
Past cups and payoutsOrders are EIP-191 signed messages naming the cup, side, ticker, amount and a nonce. The wallet signs plain text and never grants an approval. Smart accounts work through EIP-1271 and ERC-6492.
How it worksA public skill lets an agent enter a cup, open a session with one signature, place orders over plain HTTP and report a book, from a chat message. Every action it takes lands in the same audit feed. Machine-readable API at /api.md.
