Sellix for Platforms

One of the latest features we have released is the Wallet for Platform.

It enables platforms and marketplaces to issue non-custodial wallets to their merchants, then create payments from those wallets and charge merchants any custom fee whilst doing so.

It essentially is Stripe Connect but for Cryptocurrencies.

Logic flows

​

createMerchant

• implementation here
• the platform frontend calls the platform server to create a new user that will be associated with the Sellix merchant_id
• the platform server calls Sellix API using the Sellix API key (/wallet/createWalletMerchant) that returns a merchant_id and a merchant_token that will be used to authenticate the merchant
• the platform frontend will render Sellix Wallet’s /setup page in an iframe with the merchant_token as a query param
• the merchant will proceed with a regular wallet setup
• when the setup is completed the wallet makes a call directly to Sellix API (instead of using postMessage) to upload the addresses using the merchant_token:
  • /wallet/address for all the primary addresses
  • /wallet/reusable_addresses for NANO and SOLANA reusable addresses
• Concordium will not be set up at this point because it requires a different setup flow (see below)

​

getMerchantDashboard (merchant sees his wallet/dashboard)

• implementation here
• the merchant calls the platform server to get the wallet URL
• the platform server calls Sellix API using the Sellix API key (/wallet/getWalletMerchant) that returns a merchant_id and a merchant_token that will be used to authenticate the merchant
• the platform frontend renders the wallet iframe using the wallet URL with the merchant token
• the wallet uses the merchant token (instead of receiving postMessage) to make the /wallet/self API call to get the merchant addresses created during the setup phase
• the wallet uses the merchant token (instead of receiving postMessage) to make the /wallet/estimate/<currency>/reusable_addresses API call to check if there is a need to upload new addresses
• now the wallet is able to perform the following operations in a seamless way like you would do in the Sellix dashboard:
