OPINCUR (CIO)
Token Contract Migration
MONOLITH LABS LTD announces the migration of the OPINCUR (CIO) token on Solana to a new contract address. The migration is technical: it adds on-chain token metadata. Total supply, decimals and token economics stay the same.

From the date of this announcement, the new contract is the only official CIO token. The legacy contract is no longer supported.
Reason for migration
The legacy CIO token was created in 2022, when Solana projects registered token names and logos in the Solana Labs token-list repository on GitHub. That registry has since been deprecated in favor of on-chain Metaplex Token Metadata, which modern wallets, explorers and DEX aggregators use.
Because the mint authority of the legacy contract had already been revoked, on-chain metadata could not be added to it. We therefore issued a new token with on-chain metadata and migrated the full supply at a 1:1 ratio.

Holder action
At the time of migration, all CIO tokens were held in wallets controlled by MONOLITH LABS LTD, and no public trading or liquidity existed for the legacy token.
Verification
Always verify the contract address through official OPINCUR channels. Any token claiming to be CIO under a different address is not affiliated with MONOLITH LABS LTD.
