What is 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.

Circle describes USDC as "a regulated digital currency you can redeem 1:1 for US dollars" and lists Solana among the blockchains where it is issued natively. On Solana it is a token rather than the chain's own currency: balances live in token accounts tied to the USDC mint, and wallet apps usually create that account when you add the token or first receive it. Network fees on Solana are paid in SOL, so a wallet holding only USDC may still need a little SOL to send it onward.

The same asset exists on many blockchains, and the network matters as much as the currency. A Solana address is a base58 string of 32 to 44 characters; an Ethereum-style address starts with 0x. Funds sent on one network to an address that only exists on another are at best difficult to recover. Check both the token and the network before saving an address anywhere, and never share a seed phrase or private key with anyone, including a payer.

The PROXIES.SX farmer account has separate payout settings for native SOL on Solana, native BTC on Bitcoin mainnet and USDC on Solana. Its contract warns that "a SOL address does not mean a transfer is USDC" and that "saving a wallet or submitting a request does not send funds automatically". Manual requests from the farmer account can include approved, unclaimed earnings of at least $0.01. Payment method, minimum and timing are confirmed with support; no settlement time is promised here.

The separate device withdrawal API pays only to the wallet registered for the device, with minimums of $5.00 for AI agents and $10.00 for Android SDK devices and up to three requests per hour. A wallet can be changed once every 24 hours, and a change starts a seven-day cooling period before payouts, so an account takeover cannot redirect funds instantly. The wallet in the published examples is a deliberately fake placeholder; use your own address.

Where you meet it

You meet USDC on Solana as a payout option on bandwidth-sharing and other crypto-paying services, and as a field in a wallet settings page that also offers SOL or BTC. The mistakes that cost money happen at that field: the wrong network, an exchange deposit address that does not accept the token, or an address copied from an example.

How supplying bandwidth works

Common questions

Is USDC on Solana the same as SOL?

No. SOL is the Solana network's own currency and is used to pay its fees. USDC is a separate dollar stablecoin issued by Circle that lives on Solana as a token. One wallet can hold both, but a payout configured in one is not paid in the other.

Can I receive USDC on Solana at an Ethereum address?

No. Solana and Ethereum use different address formats and separate ledgers, so USDC sent on Solana needs a Solana address. If you deposit to an exchange, confirm that it supports USDC on the Solana network specifically before sending.

Which payout currencies does PROXIES.SX support for suppliers?

The farmer account has separate settings for native SOL on Solana, native BTC on Bitcoin mainnet and USDC on Solana. Saving a wallet does not send funds by itself. For device wallets set through the withdrawal API, a change starts a seven-day cooling period before payouts. Confirm method, minimum and timing with support.

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.
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.
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.
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.
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.
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.
