Renewals that outlast the card-on-file
Charge every yearly renewal to a wallet the customer already holds — no card to expire between cycles, no reissue that quietly kills a domain renewal a year out.
Why small-ticket renewals leak on card rails
Why does a $9 renewal cost so much more than 3% to collect?
Four ways card rails hurt a low-priced, once-a-year renewal business.
A fixed per-charge fee dominates a $9 renewal
A $9 .com renewal costs about $0.56 to accept on a 2.9% + $0.30 processor — roughly 6%, and the flat $0.30 is over 3% of that before the percentage is even added. Across a catalog of cheap domains, that fixed floor is a permanent drag on margin.
The card on file expires before the renewal comes around
Domains renew yearly, but cards reissue, change numbers, and expire on their own schedule. By the time the renewal fires, the stored card is often dead — so the charge fails, the failed-payment emails go out, and a domain the customer wanted to keep slips toward expiry over a payment detail, not a decision.
International ccTLD buyers can't always pay with a card
ccTLD demand is global, but a buyer abroad often can't get a card accepted by a foreign registrar — geo-blocks, low cross-border approval, hard 3DS. The buyer wants the domain and can't pay, and you lose a registration you'd otherwise have booked.
Cross-currency markup skims the foreign renewals
When a foreign card does clear, the processor typically adds a 1–2% cross-currency cut on top of the base fee, at a rate it sets. On a thin-margin renewal that markup is the difference between a profitable registration and a break-even one, before you count the failed-renewal churn. (Side-by-side in Pricing.)
How a flat percentage fits renewal economics
What changes when the renewal settles in stablecoins?
Four things that go right the moment renewals stop running through fixed-fee card rails.
No fixed-fee floor — a small renewal keeps its margin
A stablecoin payment has no fixed per-charge leg, so the cost scales with the renewal instead of swamping it. A $9 .com keeps its margin instead of giving up 6% to a flat fee. The cheaper the domain, the bigger the difference; cards do the opposite and lean hardest on the smallest tickets.
Renewals paid from a wallet — nothing to expire or reissue
The customer pays each renewal from a wallet they already hold. There's no stored card to expire between yearly cycles, no reissue that silently kills a renewal, no BIN rotation breaking the charge. The domain renews on a payment method that doesn't quietly go dead twelve months later.
Buyers abroad pay in the dollar you set — no conversion cut
A ccTLD buyer abroad pays from a wallet, no geo-block and no 3DS wall in the way, and you receive the same dollar stablecoin you priced in — no cross-currency cut, no rate set by a processor. You convert to local currency on your own schedule if and when you need it.
Roughly $0.09 to accept on a $9 renewal, not $0.56
That same $9 renewal costs about $0.09 to accept on Paymos instead of about $0.56 — no fixed-fee floor, no cross-currency cut. On a high-volume renewal book the recovered margin compounds. Full rate card in Pricing below.
How registrars wire Paymos into the renewal cycle
Which integration fits how you bill renewals?
Three ways to wire stablecoin payments into your registrar billing.
Server-side API — wired into your renewal engine
Your registrar system knows what's due and when. At renewal time it calls the Paymos API to create the invoice; the customer pays from their wallet; an HMAC-SHA256 webhook confirms settlement and your system extends the registration. Same shape as your existing gateway integration — point it at Paymos and the small-ticket fee math changes.

Hosted Checkout — registration and multi-year prepay
For a new registration or a multi-year prepay, send the customer to a Paymos-hosted page. They pay from their wallet and return with the domain booked. No card form on your domain and no 3DS to fight on an international audience — a clean fit for first-time buyers who don't have a card that clears with you.

Payment Links — bulk transfers and reseller invoices
For a bulk transfer-in, a portfolio renewal, or a reseller settling a batch, generate a payment link from your dashboard or CRM and send it over. They pay from a wallet and your receivable clears on confirmation — useful for larger one-off amounts that want a real invoice attached.

What renewal patterns run cleanly on a wallet?
Four flows from real registrar setups — single renewal, multi-year prepay, international ccTLD, and reseller batch.
Single .com renewal — invoice from the renewal engine
A standard yearly .com renewal: your engine issues the invoice and the customer pays it from their wallet. No fixed-fee floor eating a cheap renewal, no dead card on file triggering a failed charge — the registration extends the moment the payment confirms, and the customer keeps a domain they wanted to keep.
Multi-year prepay — Hosted Checkout
A customer prepays several years to lock pricing and avoid annual renewals. They pay once from their wallet via Hosted Checkout and the registration extends for the full term. No card to expire across those years, no annual failed-renewal risk — one payment, multiple years secured.
International ccTLD — direct wallet payment
A buyer abroad wants a ccTLD their card won't pay for with your merchant account. They pay from a wallet instead, the payment confirms in seconds, and the domain books — a registration you'd otherwise have lost to a decline, with no manual workaround on either side.
Reseller batch renewal — Payment Link
A reseller renews a batch of domains on behalf of their own customers. You send a payment link for the total, they pay from a wallet, and the receivable closes on confirmation. The whole batch settles in one transfer instead of dozens of card charges each carrying a fixed fee.

Honest disqualifier
When NOT to use Paymos for registrar billing
Four cases where the card stack still serves registrants better.
Auto-renew is the safety net your registrants bought
A lapsed domain can be sniped, and many registrants treat card auto-renew as insurance against exactly that. A wallet renewal needs the owner's approval every cycle — nothing can be charged without them. Keep card-on-file as the default protection layer and position the wallet for declines, dead cards, and buyers abroad.
Your registrants are all local and their cards rarely fail
The math here turns on cross-border declines, currency-conversion markup, and renewals dying on expired cards. A registrar with a domestic book and healthy approval rates sees little of that, while a second rail still adds settings, support articles, and reconciliation. Add stablecoins when international demand justifies the surface area.
Cold traffic needs the card's dispute badge to trust you
A $9 domain from an unfamiliar registrar is exactly the purchase where a buyer leans on "my card can reverse this." Stablecoin payments are final on confirmation and offer no such comfort. If your funnel converts first-time visitors, keep cards in front and let the wallet serve repeat customers and portfolio holders.
Registry bills come in fiat and you can't cash out yet
The registry leg — what you owe per domain — still gets paid from your bank account, while Paymos settles customer renewals as stablecoins to your Paymos balance. Without an exchange route between the two, revenue piles up on one side and obligations on the other. Close that loop first; the rail only works properly once it exists.
