How can I get proper and optimized gas price for fast transaction in around 10sec? I want to make my transactions to be included stably and fast in blocks. Recently I using value of “fast” returned from API of ethgasstation, but i am not sure it is reliable. Please recommend me.
Contract A interacts with another contract B, which generally interacts with humans (ie, externally owned accounts). Thus when contract B sends ETH to contract A, contract A needs a fallback function to receive the ETH. I found the function below works, though my linter warns me that this is bad form (‘no-empty-blocks’). Where’s the danger?…
For my project I created vesting contract. The contract codes and vesting contract codes are same with MATIC token contracts but in my vesting contract there is wrong. https://etherscan.io/address/0xcbfe11b78c2e6cb25c6eda2c6ff46cd4755c8fca#readContract . If you check this link there is owner and token. It is true but in my vesting contract both owner and token are same which…
While Bitcoin is the first cryptocurrency out there and is deemed to be the “gold” of cryptocurrencies, Litecoin is considered to be the “silver” of cryptocurrencies and the first follower of Bitcoin. However, are blockchains of Bitcoin and Litecoin compatible? Can they be merged into one?
How to get both confirmed and unconfirmed transaction details of foreign(non-wallet) addresses from bitcoin-node server?
How to get both confirmed and unconfirmed transaction details of foreign(non-wallet) addresses from bitcoin-node server? Actually i have generated the addresses using third party library and sent some btc on it. Now i want to know confirmed and unconfirmed transaction details using my own local bitcoin-core node server. Can Somebody help me? Thanks in advance.
I’m new into this world. I (think to) know that usually blocks are mined from most rewarded to less rewarded. So if I offer very low gas price for a transaction, it can be take a long time to be mined, if it will be. Right? I am thinking if I could setup a miner…
There are three EOA A, B, c. B has no token. TX1: A call approve B for 100 token. TX2: B call transferfrom for 100 token from A to B. TX3: B call transfer 100 token to C. If these three txs are included in same block, TX3 can success?
When looking for information about the nonce property of the genesis file, everything says that it is a 64-bit string hash etc. But which algorithm is used to generate this hash ?
Can consecutive transactions of same EOA be mined at same block as below? TX1: nonce=0, Number_confrimed_Block=100 TX2: nonce=1, Number_confrimed_Block=100 TX3: nonce=2, Number_confrimed_Block=100 Thank you for your help:)
I am using bitcoin core on regtest mode to simulate sending transactions. Is it possible to set an seed for things like generating blocks or signing transactions, so that you can recreate an exact chain of events with the same block hashes and signatures?
