Build a call
Pick a preset, or Function call to encode any function from a contract's ABI (ERC-20, Morpho, Aave, Permit2 built-in — or paste your own). Fill any argument from an on-chain read with the “ƒ” button.

Batch
⚠ Connect a Ledger or wallet to simulate or run this batch.
Run works only after the one-time on-device Delegate (Delegate / Revoke need a Ledger). Set final tx → Wallet to preview token changes in MetaMask/Rabby before signing.

7702 status
Your EOA's EIP-7702 delegation on every supported chain. ✓ Delegated = pointed at Simple7702Account (batching enabled here); Foreign = delegated to another contract; Plain = not delegated.
Revoke approvals
Source: . Scans your ERC-20, NFT (ApprovalForAll),
and Permit2 approvals on the active chain — untick anything you
want to keep, then build one atomic batch of revokes
into the Build page.
⚠ Connect a Ledger or wallet to scan and revoke.
Capture from a dApp (WalletConnect)
Connect a dApp here instead of to your wallet. Its transactions are
captured into the batch (not broadcast), so you
can send them as one atomic executeBatch. dApps that speak
EIP-5792 hand over the whole batch cleanly; legacy
dApps fire one tx at a time and will show each as "rejected" after it's
captured (expected — that's record mode). Signature requests are
forwarded to your browser wallet.
