Introduction: reading smart wallet transactions in Dune requires creative feats and work off the platform. In this article we explain how to decode EntryPoint v7 Account Abstraction calldata, extract PackedUserOps and return clean data for visualization, as well as show how Q2BSTUDIO can help with custom software solutions, custom applications, artificial intelligence and cybersecurity.
Technical context: EntryPoint v7 is part of the Account Abstraction paradigm that groups user operations into compact structures called PackedUserOps. Dune facilitates the collection of logs and calldata but does not always offer complete ABI functions to decode packed structures and complex dynamic arrays. That is why it is common to combine queries in Dune with off-chain processing to obtain complete results ready for visualization.
Step 1 extract calldata in Dune: in Dune you can write SQL queries that extract topics and data from events or transactions that call EntryPoint. Extract the calldata or input column from the transaction records and save the hex string. Use string functions available in Dune to trim offsets or identify prefixes that indicate PackedUserOps, but note that full decoding of packed structures often fails within Dune due to ABI limitations.
Step 2 prepare off-chain decoding: transfer the extracted hex strings to an off-chain process to decode them with standard libraries such as ethers or web3.py. Load the EntryPoint v7 ABI and use decodeFunctionData or decode to obtain the PackedUserOps array. PackedUserOps include fields such as sender, nonce, initCode, callData, callGas, verificationGas, preVerificationGas, maxFeePerGas, paymaster and signatures. Being packed, some fields require bit-level parsing and length concatenation before applying ABI decode.
Practical decoding details: in practice it is advisable to iterate over each PackedUserOp and reconstruct the offsets of each dynamic field to then apply ABI decode to each segment. Verify lengths using hex prefixes and validate addresses and nonces. If there is additional compression or bit-level packing, implement the appropriate masks and shifts before converting to integer types and addresses. Document the EntryPoint v7 schema and maintain unit tests for each PackedUserOp variation that appears on the network being analyzed.
Step 3 normalize and store results: once the decoded fields are obtained, generate rows in tabular format with clean columns such as timestamp, tx_hash, sender, nonce, call_type, gas_limits, max_fee, paymaster and signature. Store that data in a database or in cloud storage such as AWS S3, Amazon RDS, BigQuery or Azure Blob Storage / Azure SQL. Connect that data source to the BI layer or to Dune if you have ingestion mechanisms, or to Power BI for interactive dashboards. The recommended flow is to extract in Dune, decode off chain, then load the clean table to cloud services aws and azure or to a database that Dune or business intelligence tools can query.
Visualization and monitoring: with normalized data you can create dashboards that show PackedUserOps volume, call types, paymaster usage, fees paid and signature patterns. Use business intelligence service tools and power bi to explore and create alerts. For continuous integrations, deploy pipelines that automate extraction from Dune, decoding with scripts or lambdas and loading to your chosen data warehouse.
Limitations and recommendations: Dune is excellent for exploration and SQL queries on on-chain data but does not replace a specialized ABI decoding engine when it comes to packed Account Abstraction structures. Maintain a reproducible off-chain environment, record ABI and EntryPoint v7 versions and apply integrity tests on decoded rows before integrating them into public dashboards.
