feat(smart-contracts): BatchConversionContract 0.2.0 mainnet artifact

[yomarion]

Description of the changes

Main addition:

1. BatchConversionContract artifact for 0.2.0 (merged in fix(smart-contracts): address stranded balance issues for ERC20 #1741 and chore: audit finding "Fee Address Is Using transfer" #1739 )

The code changes only affect local commands:

• yarn hardhat deploy-contracts-through-deployer:

1. Improved error handling for lack of funds, and absence of ADMIN_PRIVATE_KEY
2. Don't try to configure contracts that could not be deployed (still do for previously deployed contracts)

• yarn hardhat verify-contract-from-deployer

1. Improved error handling with useful verbosity

Greptile Summary

This PR adds the BatchConversionPayments 0.2.0 mainnet artifact and improves error handling in the CREATE2 deployment and verification scripts. The artifact addition and most script changes are straightforward; the main correctness fixes address previously noted bugs (typo in status string, return vs continue in the deploy loop, signer guard, and optional chaining on error objects).

• Artifact: New 0.2.0.json ABI and mainnet deployment address registered in index.ts; the default exported version remains 0.1.0 for backwards compatibility.
• deploy.ts / xdeployer.ts: deployOneWithCreate2 now returns a typed {deployed, address} object; the loop in deployWithCreate2FromList correctly uses continue to skip setup only for failed contracts; xdeploy gains an early throw when ADMIN_PRIVATE_KEY is absent and a friendly message for insufficient-funds failures.
• compute-one-address.ts / verify.ts: Better diagnostic logging on error paths and verification progress.

Confidence Score: 4/5

Safe to merge after addressing or accepting the WEB3_PROVIDER_URL logging concern; the artifact addition and deploy loop fixes are correct.

The artifact addition and loop-control fixes are solid. One concrete finding remains: a new console.warn logs WEB3_PROVIDER_URL verbatim, which can expose embedded API keys (e.g., Infura/Alchemy project secrets) in CI/CD logs. Whether that risk is acceptable in a deployer-only script is a judgment call, but it is a real credential-exposure path introduced by this PR.

packages/smart-contracts/scripts-create2/compute-one-address.ts — the new console.warn on error logs the full WEB3_PROVIDER_URL, including any embedded API key.

Important Files Changed

Filename	Overview
packages/smart-contracts/scripts-create2/compute-one-address.ts	Added a console.warn on error that logs WEB3_PROVIDER_URL, potentially exposing embedded API keys in CI logs
packages/smart-contracts/scripts-create2/deploy.ts	Return type of deployOneWithCreate2 changed from string to {deployed, address}; deployWithCreate2FromList now uses continue instead of return on failure, preserving the loop for subsequent contracts
packages/smart-contracts/scripts-create2/xdeployer.ts	Added early guard for missing signer, friendly error for insufficient funds, and address log before deployment attempt
packages/smart-contracts/scripts-create2/verify.ts	Network assertion moved outside the loop and debug logging added for better visibility during verification runs
packages/smart-contracts/src/lib/artifacts/BatchConversionPayments/index.ts	New 0.2.0 entry added with mainnet address; default version remains 0.1.0 for backwards compatibility
packages/smart-contracts/src/lib/artifacts/BatchConversionPayments/0.2.0.json	New ABI artifact for BatchConversionPayments 0.2.0; ABI matches expected interface with batch payment functions and admin setters
packages/smart-contracts/README.md	Minor wording improvement to section heading

looks good!

Approved 👍 pending the small comment below 👇 🚧

I traced the SDK path: v0.2.0 is registered, and payment + approval both use the same version option.

Main note: this is opt-in. Default is still v0.1.0, so RF needs to pass version: '0.2.0' to use the new mainnet contract.

Small ops note: manual setup reruns also need the v0.2.0 address passed explicitly, otherwise the fallback points at v0.1.0.

I agree with Greptile’s warning here:

compute-one-address.ts — the catch block emits a misleading "Unknown error" warning for intentional validation failures, which could slow down debugging of deployment issues.

I checked the code too: the catch also wraps known config/validation errors like missing salt, missing deployer address, or invalid initcode as “Unknown error.”
