API Reference

Resend EVM-chain transactions

post https://api-sdk.lmnl.dev/api/wallet/resend-evm-transaction

This API is a request to resend EVM-based transactions that are stuck due to insufficient gas fee. Transactions that are broadcasted on the network, but remain unconfirmed for 10 or more minutes, are considered as stuck transactions. The API automatically detects such transactions and resubmits them with appropriate amount of fees, 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.
