How this service works
HALOWERK kettenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a structured list of on-chain transactions for the specified wallet across the requested EVM chains within the given time window, including transaction details such as timestamps, amounts, chain identifiers, and counterparties, bounded by the configured per-chain transaction limit.
Example use cases
Audit a DeFi wallet's recent moves
“Show me everything wallet 0x1234...abcd has done on Ethereum and Base in the last 90 days, up to 200 transactions per chain — I want to understand their DeFi activity.”
Monitor a treasury wallet's spending
“Check the last 7 days of transaction activity for wallet 0xDead...Beef on Arbitrum and Optimism, limit 50 transactions per chain, so I can see if anything unusual went out.”
Research a counterparty's wallet history
“Pull the full transaction history for wallet 0xCafe...1337 across all four chains — Ethereum, Base, Arbitrum, and Optimism — going all the way back, up to 100 transactions each.”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/wallet/activityWhen to prefer
Choose this endpoint when you need multi-chain EVM wallet transaction history aggregated in a single call, particularly across Ethereum, Base, Arbitrum, and Optimism. It is well-suited for agents that need to audit, monitor, or summarize on-chain activity for a known wallet address without setting up direct RPC connections to each chain. Prefer it over generic blockchain explorers when you want a paid, structured, aggregated response via the x402 micropayment protocol.
Side effects
- Invalid wallet address format (not 0x followed by 40 hex chars) returns validation error
- Unsupported or misspelled chain names result in empty or error responses
- Limit outside the 10–200 range is rejected
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Wallet with no transactions in the time window returns empty results
- Rate limiting or upstream chain RPC unavailability may cause timeouts
