Always identify a contract by chain ID plus address. The same address can identify different contracts on the two chains.

Machine-readable record and source

• Full deployment JSON: both chains, all wiring and deployment blocks.

• Deployment verification.

• Signed deployment source: 22a2783baf3a4321a05245f71f9015c18db18499; evidence commit: 291fe1903ee32f96f76818e87ba053710ab7df49.

Repository access may be required. The public integration guide includes the user-facing ABI subset and addresses, so the Mezo UI does not depend on a private repository at runtime.

August pilot — existing holders only

Open the pilot. These are not V2 addresses. The two vaults both use the symbol dMUSD but have different tokens, balances and requests. Do not combine them by symbol or move users automatically.
