What problem does it solve?

Manually managing server-side blockchain wallets for EVM and Solana chains requires handling secure private key storage, gas fee management, cross-chain operation logic, and access control rules, which is time-consuming and prone to security risks for development teams.

Core Features & Use Cases

• Cross-chain backend wallet management: Create, list, import/export, and delete developer-custody wallets for EVM and Solana, with private keys stored in hardware-backed secure enclaves to prevent unauthorized access.
• Gasless transaction execution: Send EVM transactions with automatic EIP-7702 delegation and Solana transactions via Kora fee payer, eliminating the need for end-users to hold native gas tokens, with support for atomic batching of multiple contract interactions.
• Policy and fee sponsorship control: Define granular access rules via the policy engine to restrict allowed operations, and configure fee sponsorship strategies (full developer sponsorship, custom token payments, fixed rates) to automate gas cost management.
• Use case example: A development team can use this skill to automate treasury operations, AI agent wallet functions, payroll disbursements, and cross-border stablecoin transfers across multiple blockchains without managing individual user wallet interactions.

Quick Start

Use the openfort-backend-wallets skill to create a gasless EVM backend wallet on Base, set up a fee sponsorship policy for USDC transfers, and send a batch transaction to 10 recipient addresses.
