Amounts are priced in fiat (USD or EUR) and paid in crypto. > Fiat amounts are ALWAYS decimal strings ("9.99"), never numbers. Crypto amounts are integer strings in the asset's smallest unit. > Authenticate merchant endpoints with `Authorization: Bearer tbrn_live_...`. Every key is bound to one store and carries an explicit scope set, so never pass a store id to a /v1 endpoint. > A 401 means the credential is bad; a 403 means the key lacks a scope. Never retry or re-authenticate on a 403 — surface it as a configuration error. > The /v1/checkouts endpoints are deliberately unauthenticated and run in the buyer's browser. Never send an API key to a browser. > Verify webhook signatures over the RAW request body before parsing JSON, and treat delivery as at-least-once: handlers must be idempotent. > Never grant value based on a browser redirect to successUrl. Fulfil on a signature-verified webhook, or on a server-side read of GET /v1/orders/{id} or GET /v1/invoices/{id}. > There is no test mode: every payment method is a live chain moving real funds. > A merchant can run an entire shop with no code: the dashboard creates products and invoices, and every store can host a storefront at {slug}.taberna.io with its own theme, sections, branding and optional custom domain. Never assume the reader has an API integration. > Taberna issues no refunds and performs no KYC. A refund is something the merchant sends from their own payout wallet, off-platform. # Payment methods > The coins your customers can pay with, and which ones to switch on first. You price your products in **USD or EUR**. Your customers pay in crypto, and you decide which coins you accept. Whatever you enable is what they see at checkout. Switching a coin on or off needs the owner or admin [role](/guides/team). ## The thirteen payment methods Taberna supports thirteen coins across five networks. A **network** (or blockchain) is the public ledger a coin lives on; the same coin on two networks is two different payment methods, because the money travels on different rails. | Network | Native coin | Stablecoins | | --------- | ----------- | ----------- | | Solana | SOL | USDC | | Ethereum | ETH | USDC, USDT | | Base | ETH | USDC, USDT | | Polygon | POL | USDC, USDT | | BNB Chain | BNB | USDT | A **stablecoin** is a crypto token that tracks a normal currency one-to-one, so 1 USDC is always worth about \$1. Native coins — SOL, ETH, POL, BNB — move in price all day. **There is no USDC on BNB Chain.** If you enable BNB Chain, your customers can pay in BNB or USDT there, and nothing else. ## What to switch on first Start with **one stablecoin on a low-fee network** — USDC on Base or on Polygon. Two reasons: * Your customer pays a few cents to send it, instead of several dollars on Ethereum. * The amount does not drift while they are paying. With a native coin, the price is locked for the payment window and the customer bears any movement outside it; with a stablecoin there is nothing to move. You can add more coins later at any time. More coins means more customers can pay you, so once you have taken a few payments it is worth turning on the stablecoins on every network you are willing to hold a wallet for. ## Turning methods on Payment methods are set per store, under **Settings → Payments**. Each network gets its own panel with a switch per coin. When you first [set up your store](/guides/create-your-store) you choose one network and Taberna switches on every coin on it for you. After that you turn coins on and off individually. The Payment Methods card in store settings, showing switches for each coin grouped into panels per network A coin's switch stays greyed out until you have added a payout address for its network — the panel header shows **(no address)** until you do. Enabling a network's coins is only half the job. You also need a **payout address** on that network, or there is nowhere for the money to go. See [Payout wallets](/guides/payout-wallets). ## What to read next One receiving address per network. Wallets, stablecoins and network fees explained.
