What is on-chain copy trading?
On-chain copy trading is a copy-trading model where the “leader” whose trades you mirror is identified by a public wallet address on a blockchain, and every action that wallet takes — open, close, resize, leverage change — is recorded immutably on-chain. A copy-execution layer (offered by a frontend like ARX) watches the leader's wallet, then submits proportionally sized orders from your wallet whenever the leader trades. Capital stays in your own wallet; the leader's wallet stays in their own wallet; no platform takes custody of either.
How does on-chain copy trading differ from CEX copy trading?
Three structural differences. Verifiability: A CEX shows you the leader's headline PnL from its internal books, which no third party can audit. On-chain leaderboards expose every fill, every fee, every funding payment to public inspection. Custody: CEX copy trading routes your capital through the exchange's omnibus account; on-chain copy trading never moves your USDC out of your wallet until a trade fires. Multi-account risk: CEX leaders can run hedged setups across two accounts and display only the winner; on-chain leaders cannot, because any wallet they control is publicly identifiable and analyzable.
How do you pick wallets to copy on-chain?
Four criteria matter. (1) Track record over 90+ days net of fees and funding — anything shorter is noise. (2) Maximum drawdown under 25% — higher drawdowns are psychologically uncopyable, you close at the bottom. (3) Position concentration — PnL spread across multiple assets and many trades, not dominated by one hero trade. (4) Time-in-market across regimes — the wallet should have traded in both trending and ranging conditions, not just bull-market accidental winners. The full picking framework covers the math.
Does on-chain transparency stop wash trading and sybils?
No. Transparency means anyone can verify the historical activity, but it does not prevent a sophisticated actor from creating a clean-looking wallet via wash trading, sybil cohorts, or piggybacking a single lucky run. The defense is methodology: stick to wallets with multi-month track records, drawdown discipline, and reasonable trade frequency (a few hundred trades is the discretionary shape; tens of thousands is a market-making bot). On-chain transparency makes verification possible; it does not do the verification for you.
What are the costs of on-chain copy trading?
Three cost components. (1) Trading fees on every copied trade — these are paid at the protocol level (on Hyperliquid: 0.035% taker, 0.010% maker, with maker rebates) and are the same regardless of whether the trade was self-initiated or copied. (2) Slippage from latency — your fill executes seconds after the leader's, so on a fast-moving alt you may incur 10–50 bps of slippage versus the leader's entry. (3) Funding — same as any open position, paid hourly on Hyperliquid. Frontends like ARX may add an optional service fee on top, separately disclosed.
