ABIs are fetched automatically where explorers provide verified metadata.
Ethereum Mainnet • United States
Contract Interact for protocol security teams
Read and write any smart contract method with ABI auto-detection, saved presets, and transaction simulation across supported networks. Focus on smart contract security, counterparty risk, and operational safeguards for treasuries and protocols. Provide regulators and auditors with verifiable data on asset flows, ownership, and upgrade governance. US remains the largest source of institutional crypto volume and venture-backed launches.
- Upload or fetch ABIs directly from explorers and interact through a human-readable UI.
- Raw calldata preview with decoded parameter types prevents signing mistakes.
- Session presets for frequently used contracts, including multi-sig safe transactions.
- Proactively identifying malicious approvals and upgrade patterns is tedious.

Unique insights
- Ethereum Mainnet: Base fees typically 15–40 gwei outside of NFT drops; priority fees ~1–2 gwei. Pair this with contract interact to continuous monitoring of allowance and upgrade activity with time-stamped notes..
- United States: FinCEN MSB registration, OFAC screening, and SEC/CFTC case law influence product decisions. Align risk & security analysts workflows with fewer false positives in alerting systems..
- For protocol security teams, emphasize Integrated signer selection for injected wallets, WalletConnect, and hardware devices. and track Completion of audit evidence requests without remediation findings. weekly.
Why teams rely on this tool
Core capabilities
Upload or fetch ABIs directly from explorers and interact through a human-readable UI. Raw calldata preview with decoded parameter types prevents signing mistakes. Session presets for frequently used contracts, including multi-sig safe transactions.
Audience fit
Proactively identifying malicious approvals and upgrade patterns is tedious. Fewer false positives in alerting systems.
Ethereum Mainnet focus
Uniswap, Lido, EigenLayer, and Aave drive high-value flow and require precise gas timing. Continuous monitoring of allowance and upgrade activity with time-stamped notes.
Operational playbook
- 1Load verified ABI by contract address or upload JSON manually.
- 2Simulate function call, review decoded inputs, and estimate gas.
- 3Sign the transaction with your preferred wallet and log the execution results.
Use cases
Continuous monitoring of allowance and upgrade activity with time-stamped notes. Teams must evidence internal controls and retain comprehensive activity logs for potential subpoenas.
Automated transaction decoding for SAR/STR preparation. Teams must evidence internal controls and retain comprehensive activity logs for potential subpoenas.
Cross-referencing CEX proof-of-reserve feeds with on-chain holdings. Teams must evidence internal controls and retain comprehensive activity logs for potential subpoenas.
Proof points
- Supports contract interaction on all networks within the ChainUnified RPC allowlist.
- Built-in argument validation reduces revert risk.
- Shared presets for team accounts keep governance aligned.

Frequently asked questions
Can I interact with proxy contracts?
Yes. Enter the implementation address or use the automatic proxy resolver to fetch the correct ABI before writing.
How are sensitive transaction parameters stored?
Parameters remain client-side. Saved presets store metadata without private keys or secrets, ensuring your signer retains control.
Do you provide calldata decoding for executed transactions?
Completed calls can be exported to the TX Decoder tool for plain-language summaries, making governance recaps easier.
