When you sync your node, It fetches data previously written on the Blockchain. Hypothetically, let's say that: Node is currently syncing and had fetched the 100 first blocks the first time your account was transferred some tokens were at the block 1000 In this scenario, at that precise point, if your node is still syncing, it won't have enough data to say ...

Etherscan is a closed source block explorer so we can speculate only about their behavior. From WETH contract no transfer event is generated when minting new tokens. function deposit() public payable { balanceOf[msg.sender] += msg.value; Deposit(msg.sender, msg.value); // <--- Desposit event it is not Transfer } From the ERC20 specs there's no ...

Each transactions includes a transaction nonce - an incremental number. Miners include transactions in a block so that they order by nonce and transaction price (exact implementations vary). But they have to choose some order: all transactions are always executed one after the other, no parallelism. Here's some more info about the ordering: What is the ...

Miners have latitude about the order of the transactions in a block. There is flexibility. They can also choose which transactions to include from the transaction pool. They are incentivized to pack as much as possible into a block, at the highest possible gas price. Each block has a block gas limit, a network property voted on by the miners. The ...

You have to encode tha call to transfer into the data field. 4 bytes function signature of transfer(address,uint256) 32 bytes address parameter right aligned filled with zero bytes on the left 32 bytes amount paramter For example if you want to transfer 0.2 DAI to 0xaaBBCcDDEeff00112233AaBbCcdDeEfF00112233. Your data field will be a9059cbb (function ...

There is no formula. You are waiting for a miner to pick up your transaction and include it in a block. They are under no obligation to that. They are financially incentivized to do that by the gasPrice you offered them. If it's taking too long, then offer isn't good enough. The best you can do is compare to historical norms for similarly-priced ...
