FinCobra Review

Most crypto payment gateways solve the merchant's problem by taking custody first. Payments land in a processor balance, the processor converts or holds them, and the merchant withdraws later, which reintroduces exactly the counterparty risk that accepting crypto was supposed to avoid.

FinCobra takes the other route. It builds the invoice, hosts the payment page and watches the chain, but the money moves straight from the payer to a wallet the merchant already controls.

How FinCobra Checkout Works

A FinCobra integration is three moving parts.

• Your server posts an invoice to the API with a USD amount, a product name and your own order reference. FinCobra returns an invoice id and a paymentUrl.
• You send the customer to that hosted page, which handles wallet connection, Bitcoin QR codes, address instructions and live status.
• A signed webhook tells your server when the invoice state changes. You verify the signature, fetch the authoritative invoice, and fulfil the order once it reads confirmed.

The status model is worth reading before you build against it. A payment that has been seen but not yet confirmed sits at payment_detected rather than being treated as paid, and partial or late payments open an exception that a merchant resolves deliberately, either by accepting the late payment, marking it paid out of band with a note, or closing it unpaid.

FinCobra Pricing and Fees

Billing is automatic and there are no plans to choose between. Every account starts on Free Start, which covers the first $1,000 of paid invoice volume once. After that the account moves to Pay as You Go, a flat 0.5% of paid invoice volume with no monthly subscription, billed monthly in arrears. On $12,000 of paid volume in a cycle that is $60 in fees.

What counts is narrower than the headline suggests, in the merchant's favour. Billing uses the USD amount locked at invoice creation, volume only counts once a payment confirms or is recorded out of band, invoices that are never paid add nothing, and overpayment above the invoice total is not billed. Billing invoices are due seven days after issue and an account left past due can be blocked.

The WooCommerce plugin is priced on its own terms: $99 a year with 0% FinCobra commission, or no subscription at 0.5% of confirmed order volume. Both plans get the same gateway, networks and order automation.

Network fees are a separate matter entirely. The payer covers the on-chain cost of sending, which on Ethereum can dwarf a 0.5% platform fee on small invoices and is close to nothing on Solana, Base or Arbitrum. Choosing which chains you enable is a pricing decision as much as a technical one.

Supported Coins and Chains

The asset list is short and specific.

• Bitcoin: BTC, with a unique invoice address derived from the xpub you configure. FinCobra never asks for a seed phrase or private key.
• Ethereum mainnet: USDT and USDC, through wallet-contract payments and deterministic address transfers.
• Solana: USDT and USDC, where the payer connects Phantom, Solflare, Backpack or another injected wallet and approves a direct transfer to your recipient wallet.
• Arbitrum One and Base: USDC.

One constraint catches people out: due-date invoices require an enabled USDT or USDC method, because Bitcoin is only offered on immediate invoices. If you bill on net terms rather than at checkout, Bitcoin is not available for those invoices.

Who Is FinCobra Best For?

The fit is narrow and the company is candid about it. FinCobra suits:

• SaaS companies, agencies and digital product sellers billing in USD
• Teams that want crypto revenue to stay in their own wallets rather than a processor balance
• Merchants who would otherwise self-host BTCPay Server and would rather not run a payment node
• Developer-led shops that will integrate an API and verify webhooks properly
• Projects and nonprofits that need a public donation page settling to their own wallets

It is a poor fit for anyone who needs a broad coin catalogue, fiat settlement to a bank, card acceptance or chargeback machinery, and for teams that want deeply customised self-hosted payment infrastructure.

What FinCobra Does Not Do

FinCobra is not a merchant account and not a card processor. There is no Visa or Mastercard acceptance, no ACH or SEPA, no interchange, no acquiring bank and no fiat payout. Merchants who need ordinary card payments still need a separate processor running alongside it.

Because on-chain payments are pushes rather than pulls, there are no chargebacks at all. The flip side is that there is no automatic refund either: a refund is a manual send from your own wallet, and the WooCommerce plugin explicitly does not advertise automatic refunds, WooCommerce Subscriptions or pre-orders. That plugin also is not listed on WordPress.org and has no auto-updater, so updates mean downloading a new zip from GitHub Releases and uploading it again.

Finally, treat the company itself as an open question. The terms and privacy policy took effect in April 2026, no legal entity, headquarters or team size is published anywhere on the site, and there is no track record or third-party review history to lean on yet. Non-custodial settlement limits the damage that fact can do, since FinCobra never holds the money, but availability, support and the roadmap all still depend on a company nobody can size.
