9-249: Consider refactoring repetitive code for better maintainability.Many repeated patterns (e.g., fromRequestId calls, delegate additions, declares, etc.) can be extracted into reusable helper functions. This will reduce code duplication and improve readability and maintainability.

24-32: Validate environment variables prior to usage.
Currently, private keys are assumed present in the environment. An explicit check (and user-friendly error message) would prevent undefined behavior or cryptic errors if the environment variables are missing or incorrect.
Also applies to: 34-44

43-43: New run script is clear and consistent.
The newly introduced “npm run delegate” command aligns well with the other scripts. Great addition!

13-13: Delegate script addition looks good.
The script name and command logically match the new file. No further concerns for now.

4-5: Add documentation for delegate keysThe newly added delegate private keys lack documentation explaining their purpose and usage in the context of delegate declarative payments.
Consider adding explanatory comments:

6-7:⚠️ Potential issueCritical Security Risk: Using identical private keys across roles
Using the same private key value (
0x4025da...) for different roles (payee, payer, and their delegates) is a significant security risk, even in example code. This practice could mislead users into following the same pattern in production.Each role should have a unique private key to demonstrate proper security practices:
-PAYEE_DELEGATE_PRIVATE_KEY='0x4025da5692759add08f98f4b056c41c71916a671cedc7584a80d73adc7fb43c0' -PAYER_DELEGATE_PRIVATE_KEY='0x4025da5692759add08f98f4b056c41c71916a671cedc7584a80d73adc7fb43c0' +PAYEE_DELEGATE_PRIVATE_KEY='0x9245da5692759add08f98f4b056c41c71916a671cedc7584a80d73adc7fb43c2' +PAYER_DELEGATE_PRIVATE_KEY='0x7365da5692759add08f98f4b056c41c71916a671cedc7584a80d73adc7fb43c3'🧰 Tools

2-3: Enhance security warning messageWhile the warning is helpful, consider making it more explicit about the security implications:
-# WARNING: These are example keys. DO NOT use them to store real funds! -# Generate unique private keys for each role using a secure method +# WARNING: SECURITY RISK +# These are example private keys - DO NOT use them in production or to store real funds! +# Each role (payee, payer, and their delegates) must use unique private keys +# Generate secure private keys using tools like: +# - eth-account: Account.create() +# - web3.js: web3.eth.accounts.create()
