How this service works
BitBooth Tx Explain: pay 0.005 USDC, hand in a Base-family EVM transaction hash, get back a human-readable narrative of what the tx did plus the structured signals it was derived from — 4-byte selector decode of tx.input (transfer / approve / transferFrom) and ERC-20 Transfer event log decode from the receipt. Reverted txs are surfaced explicitly so a counterparty can't pass off a reverted payment as a success.
Output
A JSON response containing a human-readable narrative description of what the transaction did, a decoded 4-byte function selector identifying the called method (e.g. transfer, approve, transferFrom), decoded ERC-20 Transfer event logs from the transaction receipt, and an explicit revert flag indicating whether the transaction succeeded or failed on-chain.
Example use cases
Verify payment before releasing goods
“Before I ship this order, can you check Base transaction 0xabc123...def456 and confirm the USDC transfer actually succeeded and wasn't reverted?”
Debug a failed DeFi interaction
“My wallet shows this transaction went through but my balance didn't change — can you decode 0x7f8e...1234 on Base and tell me what function was called and whether it reverted?”
Audit ERC-20 approve in transaction
“Can you analyze Base transaction 0x9c2d...5678 and tell me exactly what token approval was granted — which spender, how much, and whether the approve call succeeded?”
Technical details
Endpoint
POSThttps://app.heinrichstech.com/v1/cdp/tx-explainWhen to prefer
Choose this endpoint when you need to verify whether a specific Base-network EVM transaction succeeded or reverted, especially for payment verification workflows where a counterparty might present a reverted tx as a valid payment. Also ideal for agents that need to explain on-chain ERC-20 activity (transfers, approvals, transferFrom calls) to non-technical users. Prefer over raw RPC calls when you want both a narrative explanation and structured decoded signals without writing your own ABI decoding logic. Best suited for Base and Base Sepolia; not for Ethereum mainnet or other L1/L2 chains.
Side effects
- Transaction hash not found on Base or Base Sepolia — returns error indicating unknown hash
- Transaction is on an unsupported EVM chain (non-Base family) — returns chain not supported error
- Malformed transaction hash input — returns validation error
- Transaction has no ERC-20 Transfer events (e.g. pure ETH transfer) — returns narrative with empty log fields
- Payment of 0.005 USDC not received — returns 402 payment required
- Network timeout fetching RPC data — returns retriable error
