* Add EIP-1559 implementation for gas price * Improve logs * Improve comment * Rename maxFee and maxPriorityFee to use official EIP-1559 names * Delete gas price when using EIP-1559 * Allow override maxFeePerGas * Code style * Remove useless specific EIP1559 test because Hardhart support it so all transactions are using EIP1559 by default * Restore test to check legacy transaction * Update after rebase * Call eth_maxPriorityFeePerGas and returns a manual defined maxPriorityFeePerGas as a fallback * Catch JsonRpcProviderError instead of ProviderError * Improve readability * Set none value for maxFeePerGas in case of non EIP-1559 transaction * Assign none to maxPriorityFeePerGas for non EIP-1559 transaction to avoid potential side effect in wallet signing * Remove upper bound version for stew and update contractabi
