Conversation
Introduces definePermissions() which takes a contract ABI and generates ScopedAction[] with auto-computed selectors and calldataOffsets. Provides full autocomplete for function names and parameter names, and enforces correct value types per ABI parameter. Co-Authored-By: Claude Opus 4.6 <[email protected]>

Shows universal-action policy generation across deposit (3 constrained params), borrow (4 of 5 params, skipping referralCode), repay, and liquidationCall (all 5 params including bool). Co-Authored-By: Claude Opus 4.6 <[email protected]>
Shows the complete lifecycle: definePermissions → getSessionDetails → signEnableSession → enableSession on-chain → execute with session signer. Co-Authored-By: Claude Opus 4.6 <[email protected]>

Description
Adds
definePermissions(), a typesafe helper that lets developers define session key permissions using contract ABIs instead of raw hex selectors and manual calldata offsets. Given an ABI (as const), it provides full autocomplete for function names and parameter names, auto-computes selectors andcalldataOffsetvalues, and enforces correct value types per ABI parameter (e.g.Addressfor address params,bigintfor uint). ReturnsScopedAction[]that spreads directly intoSession.actions.Includes an example showing a complex multi-contract setup combining param constraints (universal-action), spending limits, time frames, usage limits, and value limits across ERC-20 and Uniswap router functions.
