Bandwidth Supply

What is Bandwidth Sharing?

Bandwidth sharing means letting a proxy network route other people's internet traffic through your connection, usually by running a small client on a phone, computer or server, in exchange for payment for the traffic carried. To the destination site, that traffic appears to come from your IP address, which is what the network actually sells.

The client does not wait for incoming connections. It dials out to the provider and holds that connection open; the provider's customers connect to a gateway, the gateway picks an available device, and the request travels down the standing connection to it. The device opens the connection to the destination and passes bytes in both directions. Because nothing has to reach the device from outside, this works on phones and home lines behind NAT or carrier-grade NAT. Cisco Talos, writing in August 2021, defined the category plainly: "Proxyware platforms enable users to sell the use of their unused internet bandwidth, typically by running a client application."

What customers pay for is the address, not the speed. A connection is classified by the network that announces its IP, and carrier and home-broadband addresses are the ones customers ask for. At PROXIES.SX that classification happens on the server by ASN: mobile carrier addresses are the highest tier, residential the middle and datacenter the base, and the type a device reports about itself is ignored. Only residential and mobile IPs can be listed for customer traffic. Rates are set per partner, may be fixed or a share of collected revenue, and the live rate is the earningsPerGB value returned when a device registers; there is no universal public percentage.

The risks sit with the connection owner, because your IP becomes the visible source of someone else's requests. Trend Micro's February 2023 research classed these apps as "riskware applications that we call proxyware", reported traffic through exit nodes that included SQL injection probing, bulk account registration and scraping of government sites, and concluded "we don't recommend participating in such schemes". Expect possible abuse complaints, and security software that may flag the client. Read your ISP's or mobile carrier's acceptable-use policy before you start: Xfinity's, checked on 27 September 2026, lists "proxy services and servers" among the equipment and servers its customers may not run.

PROXIES.SX sets conditions before any device carries traffic: bandwidth may only be shared from devices whose owners have given informed consent, the partner agreement is signed in your own legal name, listed traffic needs your own account-linked API key, and suppliers declare where their supply comes from. Those declarations are not independently verified. Registration alone does not guarantee listing, traffic or earnings. You can stop at any time without notice, and earnings already recorded stay on your account and are paid as usual. The canonical terms are published at agents.proxies.sx/peer/skill.md, which overrides any other page, this one included.

Where you meet it

You meet bandwidth sharing in app-store listings that promise money for an idle connection, in guides about what to do with an old phone, and on security blogs describing the same software turning up on machines whose owners never installed it. The questions worth asking are the same everywhere: whose IP carries the traffic, who consented, what the device can see, and how you stop.

Common questions

How does bandwidth sharing work?

A client on your device opens an outbound connection to the provider and keeps it open. When a customer of the proxy network makes a request, the provider sends it down that connection, your device connects to the destination, and the response flows back the same way. The destination sees your IP address, not the customer's.

How much can you earn from bandwidth sharing?

Nobody can tell you honestly in advance. Earnings depend on eligible traffic your device actually serves, its IP type and your terms. At PROXIES.SX the rate is set per partner and returned as earningsPerGB when you register, devices below the minimum speed are not routed customers, and registration does not guarantee traffic or earnings.

Does bandwidth sharing slow down my internet?

It uses your upload and download capacity while it carries traffic, and on a metered mobile plan those bytes count against your allowance. A PROXIES.SX device serves one customer session at a time, which bounds the load, but anything running over the same line shares its capacity with that session.

Related terms

Proxyware
Proxyware is software that turns a device into an exit point for a proxy network, relaying other people's traffic through that device's internet connection. The term comes from security research, where it covers legitimate bandwidth-sharing clients the owner chose to install and the same clients planted on machines without the owner's knowledge.
Exit Node
An exit node is the device whose IP address a proxied request finally leaves from, so the destination site sees and logs that device's address instead of the customer's. In residential and mobile proxy networks the exit is usually a phone, computer or router running bandwidth-sharing software; in Tor the same term names a circuit's last relay.
Peer Relay
A peer relay is the server that bandwidth-sharing devices connect out to, and through which customer traffic is handed down to those devices. Because each device dials the relay and keeps the connection open, it needs no public address and no open port, which is how phones and home lines behind NAT or CGNAT can act as proxy exits.
Residential Proxy
A residential proxy routes requests through an IP address that an internet service provider assigned to a home connection, so traffic appears to come from a consumer household. Lookups return the ISP's ASN and a residential classification. Pools are usually large and rotating, drawn either from real consumer devices or from ISP-registered ranges.
Informed Consent
Informed consent, in bandwidth sharing, means the device owner understands that their connection will carry other people's internet traffic, what that involves and how to stop, and agrees before any traffic flows. It separates a bandwidth-sharing app a person chose to run from proxyware placed on their device without their knowledge.
Proxyjacking
Proxyjacking is installing proxyware on a machine you have broken into, so that its bandwidth and IP address can be sold through a proxy network for the attacker's benefit. Sysdig's Threat Research Team defined the term in April 2023, comparing it to cryptojacking: the attacker profits from stolen network access instead of stolen processor time.
Bandwidth-Sharing SDK
A bandwidth-sharing SDK is a library an app developer embeds so the app can relay proxy traffic through its users' connections, with the developer paid for the traffic carried. Google Play allows proxy services for third parties only in apps where that is the primary, user-facing core purpose, and holds developers responsible for the SDKs they ship.
USDC on Solana
USDC on Solana is Circle's dollar stablecoin issued as a token on the Solana blockchain, identified by the mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. A Solana wallet can hold it alongside native SOL, but they are different assets, so a payout setting has to name the currency and the network.
