How to Spend Stablecoins: The Six Methods, Compared

The map this page draws

Six rails move a stablecoin from a wallet to a payment. Cards convert at load. Gift cards fix value at checkout. Direct payment sends the coin to the merchant. Peer-to-peer sends it to a person. Bill pay routes it at invoices. Ramps convert it to bank money in either direction. This page walks each rail once, states its mechanics, and marks its fees where the venue publishes them.

Every vendor fact below comes from the venue’s own published surface, captured 11 September 2026. A vendor appears as the source of its own fee, and never as a recommendation.

Rail one: cards

Three card forms exist. A credit form extends credit and pays rewards in crypto. A debit form reloads from a wallet app. A prepaid form carries fixed value, and some prepaid network cards are sold through gift-card marketplaces. All three settle the merchant in ordinary money over the card network. The crypto leg is a conversion at load time or purchase time, priced by the venue.

The published prices are venue-specific. At one captured venue, card purchases cost 2.5 to 3.8 percent ^[2]. Card account fees are set per venue. What generalizes is the structure: conversion first, card network second, and the merchant is never paid in crypto through these rails.

Rail two: gift cards

Gift cards convert crypto into fixed retailer value at checkout. The crypto is debited at the checkout conversion. The card is denominated in retailer value and delivered by email. The catalogs the research captured carry US-centric brand lists. That is a US-reader fact about those catalogs, not a universal one, and it bounds the rail.

Rail three: direct merchant payment

This is the rail where the merchant holds the stablecoin itself. The clearest documented example is Solana Pay, an open payments framework available to businesses as an approved Shopify integration ^[1]. Its own site describes instant settlement with near-zero fees; its own positioning calls it the first direct merchant-to-consumer rail, and this page quotes that as positioning, not as a verdict.

One discipline rides this rail. Merchant-acceptance directories exist, but merchant counts and rosters are never asserted as fact on this site. A directory is a sales surface. The rails and their mechanics are the documentable layer.

Rail four: peer-to-peer

The base rail is an on-chain transfer, and its cost is a chain fact, covered per network at the chains hub. Exchange-mediated sends add the venue’s withdrawal fee on top, and venues publish those per coin and per chain. Cross-chain sends of USDC have their own issuer path: the burn-and-mint transfer protocol, where the issuer charges nothing for the standard transfer and the senders pay gas on both chains ^[3].

Rail five: bill pay

Bill pay routes crypto through a processor to settle ordinary bills. The captured surface describes a service that connects bills to a wallet and organizes payment. The load-bearing fact is an availability condition: that service states it has been paused since 26 December 2025, with no stated resume date. A rail whose example is paused is still a rail, and the page says so plainly.

Rail six: the ramps

On-ramps convert bank money into crypto. Off-ramps convert back. The issuer-direct legs are documentable and dated. Circle Mint takes wire in and out, with outbound transfers at the actual network fee and redemption on published tiers: no daily fee on the Basic tier up to $40 million, then basis-point steps above ^{[5] [6]}. Tether’s direct channel works at a 100,000 USD minimum, with acquisition at 0.1 percent and redemption at the greater of $1,000 or 0.1 percent ^[4]. The full venue-published fee table lives on the off-ramp page.

Between the tokens there is no issuer bridge. Neither issuer redeems its token into the other’s. Conversion between USDT and USDC is always market-mediated, through an exchange or a swap service, each with its own published schedule ^[2].

Spending directly at retail

Retail acceptance has two shapes, and the difference is who holds the coin. In the direct shape, the merchant accepts the stablecoin through a dedicated rail and holds it ^[1]. In the card shape, the token is converted before the network leg, the merchant is settled in ordinary money, and only the holder ever touched crypto. A reader who wants to “pay with USDC” at a specific store is asking which of the two shapes that store uses, and the answer is a fact about the store, not about the token.

Headlines about retail adoption arrive constantly. The checkable questions are older than the headlines. Does the merchant hold the coin, or does a converter sit in the middle? Who publishes the conversion fee? Which network carries the leg? Those three answers classify any retail-payment announcement, whatever the year.

What this page refuses

No rail here is ranked. No venue is reviewed. Every fee carries its venue, its date, and its leg. Availability is regional where the captures say so. The education lock is the point: a payment method is a mechanism with a price, and the reader’s situation picks the rail.

Where to read next

The spend hub frames the cluster and the education rule. The stablecoins hub covers the tokens being spent. The USDC page holds that token’s redemption tiers in full, and the chains hub covers what a send actually costs on each network.
