Notes on USDC subscriptions on Solana: how renewals are collected, what Fianto ships, and the numbers behind it.

What is onchain commerce? Selling online when the payment is a blockchain transaction
Onchain commerce means selling online when the payment itself is a blockchain transaction: the customer signs a transfer of a stablecoin such as USDC from their own wallet, and the money lands in yours in that same transaction, with no card network or processor balance in between. In practice you still have a product page, a checkout and an order record; what changes is that there are no chargebacks, no payout delay and no card fee, and that your customer needs a wallet holding USDC and a little SOL. On Fianto the merchant pays nothing per sale, and Fianto takes no fee during the beta.
PaymentsSanctions and crypto payments: OFAC basics for small merchants
OFAC applies the same sanctions duties to a crypto payment as to a dollar one: its FAQ 560 answers "Yes, the obligations are the same", and its civil penalties generally rest on strict liability. OFAC puts some wallet addresses on its SDN list (1,063 distinct address entries in its data as of 14 October 2026, four of them Solana addresses) and says those listings are "not likely to be exhaustive". Fianto checks no list automatically: its team can block a payer wallet by hand, which stops new checkouts and renewals from that wallet.
SolanaWalletsHow to close empty token accounts on Solana and get SOL back
Closing an empty token account on Solana sends the SOL it holds as rent back to an address you choose, about 0.00149 SOL for a standard 165-byte account opened at today's rate (measured 15 October 2026). Only accounts with a zero token balance can be closed. Keep the USDC account you pay subscriptions from and the one your business gets paid into: with Fianto, a closed payer account fails the next renewal as a counted failure, and a merchant wallet without one cannot take a single new checkout.
SolanaWhat is an SPL token? Solana's token standard in plain English
An SPL token is a token on Solana that is created and moved by one of Solana's two shared token programs, rather than by its own smart contract. Each SPL token is defined by a mint account, and every holder keeps the balance in a separate token account. USDC on Solana is an SPL token on the original Token program, with 6 decimals, and a one-off payment through Fianto moves it with the Token program straight from the customer's USDC account to the merchant's.
WalletsAddress poisoning on Solana: how lookalike addresses get into your history
Address poisoning is a scam in which someone sends a tiny transfer or a fake token to your wallet from an address made to look like one you use, hoping you later copy it from your transaction history and send real money to it. It needs no access to your wallet and no signature from you until the moment you pay the attacker yourself. On Solana the defence is simple and strict: never pick an address from history; copy it from the source that created it, compare the whole string, and for addresses you send to again and again, save them once.
SolanaPayments during Solana congestion or an outage: what happens and what Fianto does
During congestion a Solana payment can wait unprocessed until its blockhash expires, and during an outage nothing new lands at all, so no money moves until blocks are produced again. Fianto rebroadcasts each signed payment until its blockhash is dead, raises the priority fee every time it retries a renewal, and never counts a network error against a subscriber: only an empty wallet, a removed approval, a frozen or a closed token account do. A transaction Fianto cannot decide is held for a person, never failed by a timer.
SolanaToken-2022 vs the original Token program: what merchants need to know
Token-2022, also called Token Extensions, is a second Solana token program at a different address that does everything the original Token program does and adds opt-in extensions such as transfer fees, a permanent delegate, transfer hooks and pausing. The original program has no extensions and will get no new instructions. USDC on Solana is on the original Token program, so none of those extensions can touch a USDC payment, and Fianto builds every transfer for that program.
WalletsComparePhantom vs Solflare vs Backpack for paying with USDC on Solana
All three can pay a USDC checkout on Solana: as of 15 October 2026 the Phantom, Solflare and Backpack browser extensions each register sign-only transaction signing through the Wallet Standard, which is what Fianto's checkout needs. The real differences are elsewhere: which browsers and hardware wallets each vendor lists, whether the wallet is Solana-only, and how the checkout hands a payment to the app on a phone. Pick by those, not by a ranking; if you already hold USDC in one of them, use that one.
CompareRequest Network vs Fianto for stablecoin payments and subscriptions
Request Network and Fianto both move stablecoins straight from payer to recipient without holding them, but they solve different jobs. Request covers EVM chains and Tron, both collecting and paying out, with invoices, fiat-priced requests and cross-chain payments for a flat 0.9% capped at $500, as of 15 October 2026. Fianto does one thing, USDC on Solana for merchants selling one-off payments and subscriptions, and the merchant pays nothing.
ProductShop themes: choosing one of 23 for what you sell
Pick the theme the editor suggests for what you sell, then change only the accent colour. Every Fianto shop theme is tagged with one to three kinds of seller (digital products, services, memberships, software, support and tips), and the Theme tab ranks up to six of the 23 under "Suggested for you". Switching later keeps your text, products and any layout you changed yourself, so the choice is cheap to undo.
ProductGetting approved on Fianto: what is reviewed and how to prepare
Before a Fianto account can take a payment, someone on the Fianto team reads what you submitted and approves it, asks for changes, or refuses it. They review a typed business profile (including anyone who owns 25% or more of a company), and the account must also have two-factor sign-in on and a receiving wallet proven by a signed message. There is nothing to upload, no review time is promised, and a refusal is final.
GuidesWooCommerce and USDC: what exists today, and two routes with Fianto
Fianto has no WooCommerce plugin. A store can still take USDC on Solana through Fianto in two ways: put a Fianto payment link behind each product, which needs no code but skips the WooCommerce cart and order, or have a developer write a small payment gateway on Fianto's checkout API, which keeps cart totals and marks orders paid automatically. If you want a ready-made crypto option inside the WooCommerce checkout, a Marketplace extension is the faster path.
