Base wallet trade history API is live on Veltra
Get any Base wallet's complete onchain trade history via API — every DEX buy and sell on Coinbase's L2, first trade to latest, in one call.

Veltra now covers Base, Coinbase's Ethereum L2. Look up any Base wallet and you get its full onchain trade history — every buy and sell across Base's DEXs — returned as structured rows through the same endpoint you already use for Solana and Ethereum.
Support is live today. Add ?chain=base to any Veltra Trade History API call and you get that Base wallet's complete buy and sell history back — first trade to latest — from a single endpoint.
Why Base
Base has become one of the busiest venues in crypto for low-fee onchain trading and new token launches. That volume is exactly what makes complete history hard to assemble and valuable to have: fast-moving wallets accumulate long trade records, and Veltra returns all of it rather than a recent slice.
What you can pull
- Complete Base 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=base to select Base:
curl -N "https://veltrabot.com/v1/wallets/{address}/history?chain=base" \
-H "Authorization: Bearer YOUR_API_KEY"Base uses 0x… addresses like every EVM chain, so select it with ?chain=base. Amounts come back in ETH, Base’s gas token.
What you can build
Base wallets power a new wave of onchain apps that need full trade context:
- Copy-trading and signal bots tracking active Base traders.
- Portfolio and PnL dashboards for Base-native users.
- Token and wallet analytics across Base DEXs.
- Backtests built from real Base trade flow.
