A dash means we found no evidence of support, not that support is impossible. Coin availability at checkout can differ by country and product.
Which network each coin is accepted on, exactly as Helius documents it. A coin and a network appearing in the same record does not by itself mean the two go together.
Each pairing above is taken from Helius’s own documentation or its named gateway’s. Absence means we found no evidence, not that a chain will fail.
Pay on the cheapest network offered — Helius receives the same amount either way, so the fee comes out of your side. Our network comparison covers which to pick.
Two ways to pay, both documented by Helius. To subscribe, pick a plan on the Billing page, choose "Pay with Crypto", enter a billing name and address, then "connect your wallet or scan the QR code and complete the payment in USDC"; the plan activates once the transaction confirms. For renewals, the default is a payment link by email and in the dashboard each cycle. The alternative is automatic: connect a Solana wallet, approve a one-time authorisation to the Solana Subscriptions Program — an open-source program maintained by the Solana Foundation and audited by Cantina — and Helius pulls each renewal in USDC without a signature. Up to three wallets can be connected, one set as default; removing a wallet revokes its authorisation. Downgrades on crypto plans take effect immediately with a prorated credit. Separately, the free "Agent" plan for programmatic sign-up requires a one-USDC payment as an anti-abuse measure.
Not documented as a refund policy. Subscriptions can be cancelled from the Billing page; crypto plan downgrades apply a prorated credit to the next cycle rather than a refund to the wallet.
Stablecoin refunds are outbound payments a merchant chooses to send, not automatic reversals. There is no chargeback.
Most stablecoin payments in this directory are one-off: buy credit, pay an invoice, scan a code. Helius sells a subscription, and its documentation describes something rare — a merchant pulling a monthly USDC payment from your wallet, with your standing permission, and no card anywhere.
“All crypto payments are made in USDC on Solana.” No network menu, no coin list to interpret. If you hold USDC on Solana you can pay; if you hold it anywhere else you cannot, until you move it.
The default is familiar: each cycle Helius emails a payment link, you open it, connect a wallet or scan a QR code, and pay. You approve every payment yourself.
The other is the interesting one. Connect a Solana wallet, approve a single authorisation to the Solana Subscriptions Program — open-source, maintained by the Solana Foundation, audited by Cantina — and Helius charges each renewal in USDC with no further signature. The rules are worth knowing before you rely on it: only your default wallet is charged; if it is short of USDC the charge is skipped, you get a payment link, and there is no retry; removing the wallet revokes the authorisation. Helius said the feature was “still rolling out” when we read the page.
Autoscaling — buying more credits automatically when you run low — needs a card and is not offered on crypto plans; you buy prepaid credits by hand instead. And there is no refund route described: cancellation stops the next charge, and a downgrade becomes a prorated credit.
OpenRouter, Venice and NanoGPT also sell developer usage for USDC, but as prepaid balances. The developer tools category has the rest, and the Solana hub explains why the network is a natural fit for a recurring sub-dollar-fee payment.
An editor confirmed these payment options against the sources listed below.
Helius's own documentation page "Pay for Helius Solana Plans with Crypto" carries the entire record. It states "All crypto payments are made in USDC on Solana", walks through the checkout, describes payment-link and automatic wallet renewals, names the Solana Subscriptions Program and its Cantina audit, and sets out the default-wallet, short-balance and cancellation rules quoted above. The billing FAQ on the same site adds the one-USDC Agent plan sign-up fee and the card-only autoscaling limitation. We did not run a live subscription. No third-party gateway is involved: the checkout is Helius's own and the recurring pull is a Solana program, which is why the provider field names the program rather than a company and the record is marked as direct wallet payment.
Payment availability can change without notice. Always confirm at Helius’s own checkout before paying. Spotted something wrong?
