Note

Modernizes docs examples by switching bigint literals to viem parseUnits/parseEther, computing start times at runtime, adding ERC-20 transfer calldata/targets for redemption, and reducing sample ETH values.

• Guides:
  • Replace bigint literals with parseUnits/parseEther and compute startDate/startTime via Math.floor(Date.now()/1000) across delegation and ERC-7715 examples.
  • Update redemption flows to use concrete ERC‑20 transfer calls:
    • Set createExecution target to USDC tokenAddress and pass callData for transfer of 1 USDC via a new config.ts.
    • Add explicit tokenAddress and callData in both smart account and EOA paths.
  • Adjust sample ETH transfer values from parseEther("1") to parseEther("0.001") in smart account user operation examples.
• Reference:
  • Align API examples to viem helpers for amounts (parseUnits/parseEther) and dynamic timestamps; add necessary imports and comments about seconds.
  • Update createExecution example value to parseEther("0.01").
  • Revise multi-token period enforcer example to use parsed amounts and remove hardcoded caveats values, keeping multiTokenPeriod config only.
