Hardhat Network and Ethers.js: Transaction Retry Logic and Nonce Synchronization

Managing Transaction Retries in Local Environments

When integrating Ethers.js with the Hardhat Network, the provider manages the transaction lifecycle by wrapping RPC calls. A challenge arises when implementing custom retry logic for transactions that fail to reach a confirmed state due to network timeouts or provider-level interruptions.

The Hardhat Network enforces strict sequential nonce management. If a transaction is submitted and successfully included in a block, any subsequent retry using the same nonce is rejected by the EVM. Conversely, incrementing the nonce for a retry to bypass this rejection can create gaps in the sequence, potentially stalling future transactions from the same account.

Given that Hardhat does not provide a native retry mechanism, the responsibility falls on the client-side implementation to determine if a transaction was actually processed before attempting a resubmission.

• How can a provider verify the inclusion of a transaction in the Hardhat Network before initiating a retry to avoid duplicate nonce errors?
• What is the recommended strategy for handling retries without creating nonce gaps that block subsequent transaction execution?
