Crossmint now provides comprehensive wallet transfer webhook support across EVM, Solana, and Stellar blockchains. This feature enables developers to receive real-time notifications when tokens are transferred in or out of wallets in their project, making it easier to track transfers, update application state, and trigger automated workflows based on transfer events. Key features include:
  • Multi-chain support - Monitor wallet activity across EVM chains (Ethereum, Polygon, Base, etc.), Solana, and Stellar
  • Token type coverage - ERC-20 tokens on EVM, all SPL tokens including native SOL on Solana, and Soroban fungible tokens on Stellar
  • Two event types - Track both incoming transfers (wallets.transfer.in) and outgoing transfers (wallets.transfer.out)
  • Detailed transfer data - Receive comprehensive information including sender, recipient, token details, amounts, and on-chain transaction data
  • Transfer lifecycle tracking - Monitor both successful and failed outgoing transfers with detailed error information
  • Seamless integration - Works with both smart wallets and EOAs across all supported chains
