DePay

  • Name: DePay
  • URL: https://depay.com/
  • Category: crypto payments infrastructure / wallet-to-wallet payment protocol / multichain checkout and plugin platform
  • Tags: ethereum-ecosystem solana-ecosystem
  • Summary: DePay is a non-custodial wallet-to-wallet payments stack with merchant widgets, payment links, plugins, and a routing layer for token conversion. The useful distinction is that this is still payment middleware and merchant orchestration, not just a protocol primitive. Read it as checkout plumbing with direct-wallet settlement.
  • What it does:
    • Lets applications and merchants accept wallet-to-wallet crypto payments directly into their own addresses without custodial settlement by DePay
    • Supports payment links, embeddable buttons, and fully controlled in-app widgets with managed and unmanaged configuration modes
    • Allows merchants to denominate prices in fiat currency or in tokens, while using real-time conversion so payers can use different assets than the receiver ultimately wants
    • Provides callback and event-webhook flows so merchants can automate post-payment fulfillment, redirect users, and observe payment lifecycle states
    • Offers checkout integrations for Shopify, WooCommerce, and World App MiniApps in addition to general-purpose developer integrations
    • Exposes the DePay payment protocol / payment router as a protocol layer developers can integrate directly into smart contracts, protocols, or other payment products
  • Key claims:
    • The homepage says DePay offers software, infrastructure, and APIs to manage payments on blockchains and highlights direct wallet payments, auto-conversion, and embeddable payment experiences
    • The benefits page says DePay payments are “peer-to-peer and non-custodial,” that transactions flow directly into the merchant wallet, and that DePay uses DeFi protocols for automatic token conversion
    • The payments docs say DePay offers links, buttons, widgets, plugins, payment APIs, and an underlying payment protocol, which is a broader product surface than a single widget SDK
    • The widget docs say developers can create managed integrations in app.depay.com, denominate payments in currencies or tokens, choose accepted token/blockchain combinations, and configure HTTPS callbacks and events
    • The widget docs show callback payloads with blockchain, transaction hash, sender, receiver, token, amount, confirmations, timestamps, and optional redirect control via forward_to
    • The support docs say DePay currently supports 10 blockchains, hundreds of wallets, and thousands of tokens, with explicit support pages for wallet standards such as WalletConnect, Ethereum extension wallets, Solana extension wallets, Solana Mobile Wallet Adapter, and Solana Pay
    • The protocol docs say the DePay payment protocol enables on-the-fly token conversion during a payment, delivers funds to the receiver, and can optionally extract a fee on execution
    • The GitHub READMEs show DePay maintaining open-source widget and button packages that support both EVM and Solana environments and expose configuration for multichain payments, fixed-currency pricing, and fee extraction
  • Whitepaper: No canonical standalone DePay whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, documentation portal, protocol and integration docs, and the public widget/button repositories; see ../whitepapers/depay-primary-sources-2026-05-02.md.
