This API is a request to resend EVM-based transactions that are stuck due to insufficient gas fee.
Transactions that are broadcast on the network but remain unconfirmed for 10 or more minutes are considered stuck transactions. The API automatically detects such transactions and resubmits them based on the feeMultiplier configured, using the replace-by-fee (RBF) mechanism, ensuring they are confirmed. If multiple transactions are stuck, the API will first resend the transaction with the lowest nonce.
