Returns recent signed, attested on-chain Polymarket trades for a specific proxy-wallet address on the Polygon network

How this service works

Recent ON-CHAIN Polymarket trades of one wallet (path param: 0x… proxy-wallet address), EACH wrapped in its own ed25519-SIGNED attestation (kind "onchain-activity"). Honest scope: Polymarket-whale on-chain activity — real Polygon transactions of prediction-market wallets — NOT general ERC-20/DEX crypto intel. Every attested row has a real tx_hash (Kalshi's anonymous prints have no on-chain identity and are excluded by construction). Signed facts per trade: tx_hash + block_time (no block number is stored, none is claimed — derive it from the tx receipt), wallet, condition_id, side, price; size_usd is included but labeled a MODELED USD notional in data_basis. Attestations are minted ONCE per tx_hash and reused (byte-stable signature per transaction), and verify FREE offline at GET /verify against the same published key as every Predge envelope. 15 min delay. Query param: limit (1-50, default 20). 404 (not charged) for a wallet with no on-chain Polymarket trades in the Predge dataset.

Output

A list of up to 50 attested on-chain Polymarket trades for the specified wallet, each wrapped in an ed25519-signed attestation. Each record includes tx_hash, block_time, wallet address, condition_id (market identifier), side (YES/NO), price, and a modeled size_usd notional. Signatures are byte-stable per tx_hash and can be verified offline via GET /verify. Returns 404 (no charge) if the wallet has no Polymarket on-chain trades in the Predge dataset. Data has approximately 15-minute latency from Polygon.
