From connected devices to contributor earnings.

CoinSurf connects applications to a residential proxy network through a Go SDK. Device activity becomes accounted bandwidth, account earnings, and payout records. We built the SDK and network services together with the workflows that let contributors manage their participation.

The contributor journey

A device connection is only the beginning.

The SDK makes bandwidth sharing available inside mobile and desktop applications. The surrounding product makes that activity understandable: which devices are connected, how much they have earned, and what happens after a payout request.

CoinSurf’s Go SDK supports iOS, Android, macOS, Windows, and Linux. Go also runs the proxy engine and traffic accounting. The control plane links device activity to contributor accounts, while the dashboard exposes device management, earnings, and transaction history.

The workflow

Connect, contribute, account, and pay.

Each stage produces information the next stage needs. A contributor can follow the result from a connected device to a recorded withdrawal.

Add a participating device
Integrate the SDK into an application or use a CoinSurf client. Device management keeps those installations associated with the contributor’s account.
Carry network traffic
Connected devices provide residential exit capacity. The network supports location selection, sticky sessions, and session lifetime controls.
Record contributed bandwidth
Traffic accounting associates network usage with devices and accounts. The dashboard presents current balance, daily earnings, and earnings over time.
Request and track a payout
Contributors configure a payment destination, request a withdrawal, and follow its status in transaction history. Payout options include PayPal and crypto wallets.

What we built

The account keeps participation visible.

Devices

See the installations behind the balance

Device management and connected-client views expose the network’s contributors. Country and application-version filters help inspect the active client base.

Earnings

Separate earned funds from withdrawals

Balance and earnings views describe accumulated value. Transaction history records withdrawal requests and their status, giving contributors a way to follow a payout after submitting it.

Referrals

Track another source of earnings

Referral records show referred participants and the earnings associated with them. The programme sits alongside bandwidth income in the same contributor account.

In operation

A shared implementation across mobile and desktop.

The Go SDK and server proxy engine support the same bandwidth-sharing service across five operating systems. The network implementation includes QUIC, TCP, HTTP, and SOCKS5, with authentication and encryption for connections.

Publishers can integrate the SDK into their products; contributor applications can expose device, earnings, and payout workflows through the API. Enterprise integrations also include the dedicated support and SLA arrangements described in the project.

Engineering stack

Technology behind the platform.

CoinSurf uses Go for its SDK, proxy connections, and traffic accounting. The control plane manages the service through a Django API, with separate storage for account data and analytics.
