Ethereum wallet trade history API is live on Veltra

Ethereum wallet trade history is now available from Veltra. Query any 0x address and you get the wallet's complete ERC-20 buy and sell record across Uniswap and the major Ethereum DEXs — the same structured trade rows Veltra returns for every chain, over a single endpoint.

Support is live today. Add ?chain=eth to any Veltra Trade History API call and you get that Ethereum wallet's complete buy and sell history back — first trade to latest — from a single endpoint.

Why Ethereum

Ethereum wallets carry the longest histories in crypto. A DeFi user's address can span years of swaps, and reconstructing that from the chain yourself means parsing logs across thousands of blocks. Veltra hands you the finished trade history so you can go straight to PnL, analytics, or a backfill without building an indexer first.

What you can pull

• Complete Ethereum trade history — every buy and sell a wallet has ever made, not just the most recent few thousand.
• Structured trades — side, token, amount, DEX, and timestamp on every row, ready to use.
• Amounts denominated in ETH, the chain's native token.
• Stream the whole history on one call, or page through it with a cursor — your choice.

Make your first call

Authenticate with your API key and pass ?chain=eth to select Ethereum:

curl -N "https://veltrabot.com/v1/wallets/{address}/history?chain=eth" \
  -H "Authorization: Bearer YOUR_API_KEY"

Ethereum addresses are 0x…, so pass ?chain=eth explicitly — every EVM chain shares the same address format and cannot be inferred from the address alone. Amounts come back in ETH.

What you can build

Complete Ethereum history is the foundation for most serious wallet tooling:

• DeFi portfolio trackers that reconcile a wallet down to its first swap.
• Tax and accounting tools that need every disposal event.
• Wallet reputation and scoring for lending, airdrops, or risk.
• Research datasets on Ethereum trading behavior.

Pricing

Trade history is billed on volume at $0.01 / 1,000 trades pay-as-you-go, with monthly plans at a volume discount. Every trade counts toward your usage once — paging back over trades you already pulled never double-charges. Start with 100,000 trades free, no card required.
