Smart traders

The wallets that made repeated, verifiable profit over the last 1, 3 or 7 UTC days (today included): bots, launch wallets and lucky one-offs removed by named rules, then ranked by a luck-corrected score. Rebuilt every 10 minutes on the Solana side (computedAt); the request never computes, so it answers in milliseconds, and 503 for a few minutes after a deploy until the first build.

How a wallet gets on the board:

• Profit you can stand behind. Realized PnL at average cost over the whole window (a position bought on day 1 and sold on day 3 counts), from swaps in pools quoted in SOL, USDC or USDT only. A position with more than 10 % of its amount traded through pools quoted in another token is left out (unpricedTokens), and so is one returning over 1,000× its cost or selling more than the token's deepest pool could pay (suspectTokens).
• A person, not a machine. Removed by name (checked.flags): cadence (over 500 swaps on a day), sniper (over 150 tokens on a day), burst (8+ transactions inside a minute, in more minutes than the wallet has active days), sameslot (sells within 2 s of buying, 5+ and 5 %+ of its sells), arb (transactions that buy and sell one token), scalp (median hold under 60 s: gone before anyone could follow), launch (most closed positions first bought within 2 s of that pool's first swap: creator and bundle wallets).
• One operator, one row. Wallets that made their first buy of the same 3+ tokens within 2 s of each other are one operator: the best score stays and carries siblings; a follower 30 s behind is not grouped.
• Not luck. At least 5 tokens bought and sold, 10 swaps, $2,000 of volume, $1,000 realized and a 30 % win rate.
• Score = realized × (0.35 + 0.65 × win rate shrunk toward 50 % with 20 phantom positions) × (0.5 + 0.5 × profitable days / active days) × (0.5 when one token made over 80 % of the profit, 0.75 over 60 %) × exp(−hours since the last trade / 48). rules repeats every threshold in words.

Candidates are the top 250 wallets by realized PnL in the window, so sort=roi and sort=winrate reorder that verified set rather than search every wallet; roi only ranks wallets that put at least $1,000 to work. from is where the window really starts: never before coverageSince. Unrealized PnL (unrealizedPnlUsd, held amount marked at most at the deepest pool's liquidity) is shown, not ranked. Past profit over a few days is not a forecast.

Chord's own Solana tape, read-only. No key needed.

• What it reads. The swap events of 11 venues: PumpSwap, the pump.fun bonding curve, Meteora DBC, Meteora DAMM v2, Meteora DLMM, Meteora pools (dynamic AMM v1), Raydium CLMM, Raydium CPMM, Raydium AMM v4, Raydium LaunchLab and Orca Whirlpool. Each swap is checked against the pool vaults' balance changes in the same transaction.
• What it does not read. Prop AMMs (SolFi, HumidiFi and the like) and order books. SOL/USDC and other major pairs therefore show far less volume than the whole market; the numbers are accurate for pump.fun, Meteora and Raydium style tokens. Transfers are not seen either: wallet PnL is average cost inside the window.
• History. Live since 2026-10-03 12:01 UTC, plus a backfill of the days before. coverageSince on /chains/solana/overview says from when totals are complete: quote that field, not a date.
• Addresses are base58 and case-sensitive. Never lower-case a mint or a wallet: a lower-cased mint is a different string, refused with 400 BAD_ADDRESS when it stops being base58 (an L becomes l) and answered 404 TOKEN_NOT_FOUND otherwise. Solana has no numeric chain id here: the path segment is the literal solana.
• Units. Token amounts are whole tokens (decimals already applied), quoteAmount is whole units of the pool's quote (SOL, USDC, USDT or the other token), prices and *Usd fields are US dollars. Timestamps, updatedAt included, are Unix seconds.
• Names are untrusted. symbol, name and image are whatever the token's creator wrote; many mints share a symbol and there are no wash or impostor flags. Identify a token by its mint.
• Errors. 400 BAD_* for a bad parameter; 400 UNSUPPORTED_CHAIN if Solana is not public on the deployment and the request has no X-API-Key; 503 CHAIN_DATA_UNAVAILABLE when the Solana store cannot be read in time and 503 CHAIN_NOT_ENABLED when the lane is off: retry later, never read either as "no trades".
