TailWins copies trades from wallets you choose, on Solana, Robinhood Chain, Base, Ethereum and BNB Chain. It is not a broker, exchange, investment adviser, or fiduciary. Using it can result in the loss of some or all of the money you commit. If you are not comfortable with that, do not trade.
Positions can and do go to zero. Copying another trader does not reduce this risk — you may buy at worse prices, at different times, or after the edge is gone, and the trader you follow can lose too. Only commit money you can afford to lose entirely.
All trader statistics, profit curves, win rates, and the TailWins Skill Score are historical, on-chain data about third-party wallets. They describe what already happened. The skill score measures past edge on resolved markets and tests it against luck, but a past edge — even a statistically proven one — is not a forecast, a recommendation, or a promise of any future outcome.
Where TailWins states what copying returned, the figure comes from a simulation over real market data, run July 2026: 174,732 trades by 300 Polymarket International accounts with verified positive lifetime P&L. For each trade, the copier's fill was taken from the actual market tape — the first same-side trade by a different account within a 60-second reaction window (fills existed for ~60% of trades; the rest were treated as missed, not imputed) — and settled against the market's real resolution, net of the venue's published taker fees. Copying cost roughly 0.8–1.0¢ per $1 share versus the copied trader's own fill. Net results were positive only for traders ranked in the top quartile by the skill score, measured on a held-out, later time period (+1.4¢ per $1 share overall). Measurement windows were short — 4 to 61 days depending on category — and none of this predicts future results.
The Solana figures come from 191,834 on-chain fills by 1,554 wallets, priced in a single currency and clustered by token — one result per token per wallet, never one per trade, because a wallet that traded one token a thousand times has told you about one token.
Does the ranking predict? Wallets were ranked on trades that closed before a cut-off date and scored on trades that closed after it, at six different cut-offs. The top tenth beat the bottom tenth at all six. The order carries real information.
Does the top of it make money? No, on the evidence we have. The top tenth’s median result was negative at every one of those six cut-offs, and its average across them was not distinguishable from zero. Across all wallets, the typical round trip lost about 10% after costs, and roughly a quarter of tokens produced a positive median result.
We also tested nineteen ways of exiting a copied position — fixed holding times, take-profits, stop-losses, trailing stops. None of them was profitable, and every longer holding period was worse than every shorter one. These assets decay.
We publish this because it is what we found, including the parts that do not help us. It is historical measurement of third-party wallets and does not predict what any wallet will do next.
TailWins is free to use. There is no subscription and no monthly fee. We take 0.89% of each trade placed through the service, taken on-chain at the moment the trade executes, and nothing else — no deposit fee, no withdrawal fee, no inactivity fee. Network fees charged by the blockchain itself are separate and are not ours.
Trades on other networks cost more. On Robinhood Chain, Base, Ethereum and BNB Chain the route is built by LI.FI, an aggregator that takes roughly 0.25% of the trade on top of our fee. That is theirs, not ours, and we do not receive it — but you pay it, so an EVM trade costs about 1.05% against 0.89% on Solana.
Moving money between networks costs about 1.5%. If a copy needs to happen on a network your funds are not on, we bridge what it needs and trade. Measured on real routes, a transfer loses roughly 1.5% to 2.8% depending on size — mostly fixed costs, so smaller transfers lose a larger share. We move a working balance rather than a per-trade amount for exactly that reason, and we never take a fee on the transfer itself. You can bring funds back to Solana at any time from Deposit / Withdraw.
Nothing on TailWins is financial, investment, legal, or tax advice, and no content is personalized to you. Rankings and scores are informational only. You are solely responsible for your own decisions. Consider seeking independent professional advice.
When you enable live trading, Auto-Mirror places real orders on the account you connect, automatically, according to the settings you choose. You are responsible for every trade it places. It can misfire, place trades you didn't anticipate, or fail to place trades you wanted, including because of market moves, slippage limits, downtime, or errors. Set conservative caps and monitor it.
Your wallets. Two are created for you and both belong to you: a Solana one, and — because Solana and Ethereum-style chains use different key types and cannot share an address — one for Robinhood Chain, Base, Ethereum and BNB Chain. You can export either into Phantom, MetaMask or any compatible wallet at any time. We do not hold your keys; they stay inside the wallet provider's secure enclave, where neither we nor the provider can extract them. What you grant us is a signer on those wallets, which is what lets our server place trades, and move funds between networks for them, while you are asleep.
Be clear about what that signer can do: it can sign any transaction from the wallet, including transfers out. That is not incidental — it is how the Withdraw button works. We sign only what you asked for: the copy rules you configured, trades you place yourself, stop losses you set, and withdrawals to the address you enter. You can revoke the signer at any time, which immediately stops all of it and leaves the wallet entirely yours. Because a signer is powerful, fund this wallet only with what you intend to trade.
Prediction markets. A legacy Polymarket integration still exists for accounts that connected one. TailWins never holds your USDC; the software uses the credentials you connected and only ever places Polymarket orders — never withdrawals or transfers. Credentials are encrypted at rest and can be deleted at any time, which immediately stops all activity.
Meme coins are the riskiest thing on this site and the risks are not the same as a prediction market's:
TailWins is an independent product. It is not affiliated with, endorsed by, sponsored by, or connected to Polymarket or its operators. Polymarket has its own terms, restrictions, and eligibility rules, which may change; your use of Polymarket is governed by Polymarket, not by TailWins.
Prediction markets are restricted or prohibited in some jurisdictions and for some persons. You are responsible for determining whether your use of Polymarket and of TailWins is lawful where you are, and for complying with all applicable laws. Do not use these services if they are not permitted for you.
Software, networks, blockchains, and third-party services can fail, be delayed, be attacked, or behave unexpectedly. This can cause missed trades, duplicate trades, wrong sizing, or losses. We work to reduce these risks but cannot eliminate them, and we do not guarantee availability, accuracy, or performance.
