StablePay SDK is updated to support Ethereum Classic Mainnet with chain ID 61, associated RPC and contract addresses. The existing ETC testnet configuration is renamed to "Mordor Testnet" for clarity.

Changes

Cohort / File(s)	Summary
Network Configuration Updates license.md	Adds Ethereum Classic Mainnet configuration (chain ID 61, RPC endpoint, Djed Contract address, and ECSD stablecoin address); renames ETC testnet configuration to "Mordor Testnet"

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10–15 minutes

• Verify that the Ethereum Classic Mainnet chain ID (61) and RPC endpoint are correct and operational
• Confirm contract addresses (Djed Contract and ECSD stablecoin) are accurate via provided verification sources (Blockscout, on-chain calls)
• Ensure testnet rename doesn't break any dependent configurations or documentation

Poem

🐰 Classic Ethereum now hops into place,
Mainnet joins the stable blockchain race,
Mordor stands guard on testnet side,
With verified contracts as our guide,
Config complete, the SDK takes stride! 🚀

⚠️ Potential issue | 🟡 Minor

Wrap the bare URL in markdown link syntax.

The RPC URL should be formatted as a markdown link or wrapped in backticks/angle brackets to comply with markdown standards.

Apply this diff to fix the markdown formatting:

-RPC: https://etc.rivet.link
+RPC: <https://etc.rivet.link>

Alternatively, use inline code formatting:

-RPC: https://etc.rivet.link
+RPC: `https://etc.rivet.link`

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In license.md around line 12, the bare RPC URL "https://etc.rivet.link" should
be formatted as a markdown link or inline code; replace the plain URL with
either a markdown link (e.g., link text pointing to the same URL), or wrap the
URL in backticks or angle brackets so it renders correctly in Markdown.
