Modveon Launches El Salvador’s Sivar App for Dollar Transfers on Base Network

How Does Sivar Ensure User Control Over Funds?

El Salvador’s government-backed digital payments platform Modveon has introduced the Sivar app, enabling users to send and receive U. S. dollars via the Base blockchain. The app leverages self-custodial wallet technology, giving individuals full control over their funds without relying on third-party custodians. Launched this week, Sivar aims to streamline cross-border transfers for Salvadorans both domestically and abroad, particularly targeting remittance flows that are vital to the national economy. The initiative reflects El Salvador’s ongoing effort to integrate blockchain solutions into everyday financial services following its adoption of Bitcoin as legal tender.

The Sivar app distinguishes itself by charging a flat $2 fee for cross-border processing, which is applied separately from any costs associated with funding the wallet or withdrawing cash. This transparent fee structure is designed to reduce the complexity and hidden charges often found in traditional remittance services. By operating on the Base network—a secure, low-cost Ethereum layer-2 solution—Sivar ensures fast settlement times and minimal transaction expenses. Users can hold, send, and receive dollars in digital form while maintaining ownership of their private keys, enhancing security and autonomy. The government has positioned the app as a tool to expand financial inclusion, especially for unbanked populations reliant on informal money transfer channels.

What Are the Implications for Remittance Costs in El Salvador?

Sivar employs self-custodial wallets, meaning users alone hold the cryptographic keys needed to access their funds. Unlike custodial services where a company manages assets on behalf of users, Sivar does not store or control user private keys. This design minimizes counterparty risk and aligns with principles of decentralized finance. The app interface allows users to manage their keys securely through biometric authentication or encrypted backups. Government officials emphasize that this approach builds trust by putting financial sovereignty directly into users’ hands.

With remittances accounting for nearly a quarter of El Salvador’s GDP, reducing transfer fees has significant economic potential. The $2 cross-border fee on Sivar is notably lower than average charges from traditional providers, which often exceed 5% per transaction. By cutting costs, the app could increase the net value of funds received by families, boosting local spending and savings. Analysts suggest that widespread adoption might pressure other services to lower their fees, creating broader market benefits. However, success will depend on user uptake, network reliability, and public education about self-custody risks.

How does the Sivar app differ from other digital wallets in El Salvador? Unlike custodial wallets offered by banks or fintech firms, Sivar gives users complete control of their private keys, ensuring no third party can access or freeze funds. It operates on the Base blockchain for low-cost, transparent dollar transfers.
