Sig Zero Inc.: MozaikPay Extends USDC Operations onto Solana Network
By Rus · Chief of Staff · 19 Oct 2026
MozaikPay users can now move USDC between their Solana wallets and the app, with full control over keys remaining in their hands.
Users who hold USDC inside the MozaikPay app receive direct access to Solana deposits and withdrawals from within the same interface.
MozaikPay said on Oct. 12, 2026 that its self-custodial USDC wallet is live on Solana. Holders can deposit USDC from a Solana wallet into the app and withdraw it back to Solana. The transfers use Circle CCTP for the cross-chain portion.
Deposit and Withdrawal Process
Once the feature is active, a holder opens the app and selects the option to bring USDC from a Solana wallet. The same holder can later move those funds out of the app and back onto Solana. Both actions happen inside the MozaikPay interface without requiring external bridges.
After funds sit in the app, the holder can send USDC to any other MozaikPay user. The app treats the balances as digital dollars that power these transfers.
Self-Custodial Design
MozaikPay operates as a self-custodial wallet. The user alone holds the keys and controls the funds at every step. Sig Zero Inc., the company that developed the app, states it cannot access user funds or reverse any transactions.
The wallet runs on both iOS and Android. This setup keeps ownership with the individual rather than routing control through a third party.
Cross-Chain Mechanics
All cross-chain movements rely on Circle CCTP. The protocol handles the movement between networks while the app presents the options to the user. Holders therefore see a single flow for both deposit and withdrawal actions.
The announcement from Oct. 12, 2026 marks the moment these capabilities became available. No additional steps or external accounts are needed beyond a Solana wallet address and the MozaikPay app itself.
Practical Ownership Outcomes
A holder gains the practical ability to keep USDC in one place yet route it to Solana when needed. The same holder retains the option to bring those funds back into the app for sending to other users. All activity stays under the user’s key control.
Sig Zero Inc. positions the product as a payment app where the user manages balances and transfers directly. The Solana integration extends that control to another network without changing the custody model.
The update keeps the focus on what the holder can do inside the existing app rather than requiring new accounts or separate services.
