Possible values for the field transaction_type:

Value	Description
reward_mine_uncle	Uncle block rewards are awarded to miners who generate an uncle block that gets included in a valid block added to the chain. These uncle blocks are analogous to stale blocks in Bitcoin. However, rather than being disregarded, uncle blocks receive rewards dependent on their novelty.
reward_mine_block	Rewards granted to the miner who mines the current block.
dao_refund_contract	This is related to the execution of the DAO hard-fork, an event that occurred as a response to the notorious DAO hack in 2016. This hard-fork moved all the Ether initially stored in The DAO (and its child DAOs) to a refund contract. From this contract, original DAO token holders could claim their proportional share of the funds.
dao_adjust_balance	Refers to any adjustment made to an account’s balance in relation to DAO-related hard-fork or operations.
coin_transfer	A coin transfer operation.
genesis_balance	Refers to the balance attributed to addresses during the genesis block.
gas_buy	The amount of gas purchased by the initiator to execute the transaction.
reward_transaction_fee	Reward earned by the miner for including the transaction in the block.
reward_fee_reset
gas_refund	The process of refunding gas to the initiator when the state store is cleared.
touch_account	Refers to the process of interacting with an account in some way, such as updating its nonce.
suicide_refund	The process of refunding gas to a contract owner when the SELFDESTRUCT operation is called, as it clears the store.
suicide_withdraw	This action allows the withdrawal of the remaining coin (ex: ETH) in a self-destructed account to a specific address.
call_balance_override	This operation overrides the default balance of an account.
burn	Burning coins in chains where this process occurs.
withdrawal	Allows the withdrawal of rewards or stake for validators.
token_transfer	This operation involves the transfer of (ERC20) tokens.
wrap_coin	This operation mints WETH tokens after a coin (ex: ETH) deposit.
unwrap_coin	This operation burns WETH tokens before a coin (ex: ETH) withdrawal.
token_deposit	This operation allows the deposit of (ERC20) tokens into staking contracts or escrow.
token_withdrawal	This operation allows the withdrawal of (ERC20) tokens from the staking contracts or escrow.
unknown	Unknown balance_change reason, only happens for the chain’s coin.
