A terminal-based execution client for EVM chains.

Wyvern CLI runs locally on Windows and turns a CSV file into signed, broadcast transactions. Each row is one task: contract address, function name, parameters, ABI, nonce, gas mode, priority fee, transaction cost. No GUI, no hosted backend, no wallets leaving your machine.

Transaction control

• Call any function on any contract, verified or not — supply the ABI and parameters yourself
• Per-task gas mode, gas fee, priority fee and gas limit
• Flashbots submission
• Send-on-pending triggers off a target contract, sender or function
• Nonce control, bulk speed-up and cancel on in-flight transactions
• Quicktasks and configurable retry delay

Wallet tooling

• Generate wallets in bulk
• Check balances across a set
• Distribute funds out, recollect back into one
• Fetch and recollect ERC-721 tokens across wallets

Monitoring

• Discord webhook for transaction status
• Status bar with latest block and mint activity
• RPC connection testing, custom RPC endpoints, on-chain fee estimation
