How to compare crypto payment processors: custody, fees, settlement speed, supported networks and what happens if a provider shuts down, and why non-custodial processing keeps your funds in a wallet you control.
What a non-custodial crypto payment processor really means, why custody is the hidden risk in card and exchange rails, and how settlement-is-the-payment works.
CoinPayments is custodial by default, stopped serving EU/EEA clients after 1 July 2026 under MiCA, and asks every merchant to sign up and pass KYC again on its new platform. Six CoinPayments alternatives compared on where the money lands, published fees, coins and networks and what you have to run: Payzum, DepiPay, BTCPay Server, NOWPayments, BitPay and CoinGate. Plus when staying is the right call, a Payzum vs CoinPayments table and a step-by-step migration that keeps your CoinPayments-format IPN handler.
BTCPay Server is free, non-custodial and Bitcoin-first. Stablecoins only arrive through community plugins: USDT on TRON, Ethereum or Polygon via the Tether USDt plugin, USDt on Liquid, and USDC only by swapping it into bitcoin. Here is what each route takes to run, the stablecoin alternatives (Payzum, a third-party BTCPay host, Solana Pay, a plain address), a Payzum vs BTCPay Server table, the break-even math against self-hosting, and how to run both side by side or move step by step.
BitPay is custodial even when it settles in crypto: it credits each payment to your BitPay ledger and forwards it in a daily batch, with minimums. Five non-custodial BitPay alternatives compared on where the money lands, published fees, coins and networks and what you have to run: Payzum, BTCPay Server, Blockonomics, Solana Pay and a plain wallet address. Plus when staying with BitPay is the right call, a Payzum vs BitPay table and a step-by-step migration with the webhook and status changes mapped.
Eight Coinbase Commerce alternatives compared on custody, coins, networks and who can sign up: Payzum, BTCPay Server, NOWPayments, Coinbase Business, Shopify Payments USDC, BitPay, CoinGate and Stripe's stablecoin payments. What Commerce merchants lost on 31 March 2026 (self-custody, hundreds of assets, sign-up from anywhere), how to get funds out of an old Commerce wallet, and a step-by-step migration with the webhook and status changes mapped.
On October 14, 2026, Tempo made Zones generally available: private stablecoin accounts for payroll, contractor payouts, B2B payments and treasury, with Deel first in production. Tempo's own write-up names the leak merchants live with — every settlement shows your volume. Here's what a stranger can read from your receiving wallet, why privacy reached payroll before the checkout, and what to change today.
Six NOWPayments alternatives compared on custody, where the money lands, stablecoins and in-person sales: Payzum, BTCPay Server, CoinPayments, BitPay, CoinGate and Stripe's stablecoin payments. Why new NOWPayments accounts start in Custody since May 2026, a head-to-head Payzum vs NOWPayments table, and a step-by-step migration that keeps your IPN handler: same x-nowpayments-sig header, five statuses to map.
On October 9, 2026, roughly $100 million was drained from hundreds of wallets set up on Ledger devices sold by CryptoBilis, an authorized reseller in Southeast Asia. Ledger confirmed an unauthorized hardware implant the next day, and its own documentation says Genuine Check can't detect one. The attacker waited months for balances to grow. The lesson for businesses: self-custody fails at the device and the seed, so design for one compromised device: buy direct, keep receiving wallets small, put treasury behind multisig.
A buyer's checklist for small businesses choosing a stablecoin payment processor: where the money lands, how fast it's final, what a sale really costs at your average ticket, the coins and networks your customers hold, one account for the counter and the website, plugins, refunds and exit risk, and who answers when something breaks. With card-fee math checked on 19 October 2026, use cases and a side-by-side table.
Payzum has not opened a funding round yet. A raise is planned, and investors can join the waiting list at waiting.list@payzum.com. This post sets out where the company stands, how it makes money, the four parts of the investment thesis (a live product, accounting, a non-custodial model and payments for AI agents) and the risks an investor should weigh.
On September 24, 2026 attackers drained about $387.5 million from Bitget's hot and warm wallets by spoofing transaction data inside its backend. Withdrawals paused and restart in phases through October 2 — USDC and fiat last — while deposits and trading stayed open. Bitget says balances are intact and its protection fund covers the loss. What that means for any business whose customers pay into an exchange deposit address, and how to move crypto revenue to a wallet you control.
On September 18, 2026, Stable.com connected to Polygon's Open Money Stack so USDT and PYUSD holders can initiate a bank transfer straight from their own wallet, with no deposit into a platform account first. It is a small integration with a large implication: the exit from stablecoins was the last place merchants were still forced to hand over custody. Here's what it fixes, what it doesn't, and why the money-in side is the half you actually control.
On July 29, 2026, Paris-based stablecoin card issuer Kulipa stopped operating over solvency problems. Around 120,000 cards died mid-checkout across roughly 20 client platforms, four months after a $6.2M seed round. No wind-down email, no grace period. And yet not a single user balance was lost — because the cards spent straight from self-custodied wallets, so there was no pooled float to freeze. Analysis of what a crypto payment provider shutdown actually costs, and why custody is the only question that changes the answer for a merchant.
On July 31, 2026 the introductory 0.99% rate on PayPal's Pay with Crypto expired, stepping up to a scheduled 1.5% — a 51-basis-point increase on every crypto sale, on a date the merchant never chose. Analysis of why percentage pricing has nothing to do with what a blockchain actually charges, what that 1.5% is really buying (custodial conversion, not settlement), where independent research puts the rest of the market, and why merchants who want to control their own cost per sale should be settling non-custodially to a wallet they own.
Card processing quietly takes 2–3.5% of every sale. Here's how to avoid 3% card fees by accepting USDC/USDT stablecoin payments for 0.5% per sale plus cents in gas: non-custodial, no chargebacks.
