Relays are not part of the protocol. They are an emerging pattern for user-facing UI's that simplify user-onboarding by adding flexible payment options for the gas. Users can transfer tokens and interact with contracts without having any ether. Suppose Alice wants to send a transaction to a Contract using Bob to relay the transaction. Alice signs the ...

There is no such thing sendrawtransaction. There is signTransaction, which returns a raw (signed) transaction. You obviously don't need a private key at this point, since this raw transaction has already been signed; you can send it as is via sendSignedTransaction.

Solution: On Ganache: the default gasLimit is 6721975 you can pass that value as the gasLimit for the execution of your transaction. On other networks say ...

tornado.cash is a mixer that has received a fair amount of attention. As the site states, it has been audited, but is still considered experimental. I'm not knowledgeable enough to comment on what it takes to deanonymize transactions from an anonymity pool, though bear in mind an advantage of Tornado is that it has a very specific menu of amounts that can be ...

From Solidity read the docs: Array: Arrays can have a compile-time fixed size, or they can have a dynamic size. Indices are zero-based. Takeaway: Solidity does not support heterogeneous arrays yet, i.e. the indices for arrays are integers and not any other value. Mapping: Mapping types use the syntax mapping (_KeyType => _ValueType) and variables of ...

Most likely your transaction is underpriced and it wasn't added in any block yet. This is why it is stuck in pending mode. At this moment the network is "clogged". There is a website where you can check the recommended transaction gas pricing. https://ethgasstation.info/

Let's say there are two contracts TRC20 which is a token and SaleOfGoods which has the salesOfGood function. The problem is in saleOfGoods function function saleOfGoods(string memory _nameOfgood, uint _amountOfgood) public { // .... trc20.approve(address(0xeBa84a3f7d8d70955bEFF633098D8d6A3a6c18e5), msg.sender, walletOfGoods[msg.sender][_nameOfgood]....

If you want to calculate the block transaction fee, you can calculate it as follows: eth_getBlockByNumber get block info. Get the above block info Get the hash of each transaction. eth.getTransaction get gasUsed. eth_getTransactionReceipt get gasprice. gasUsed * gasPrice get transaction fees. Add up all transaction fees.

Your on, once and then are wrong. Please try as below: this.state.token.methods.approve(this.state.neutralG.address, qty).send({ from: this.state.account}) .on('receipt', (receipt)=>{ this.callCreateEscrow(); console.log('receipt'); }) function callCreateEscrow(){ this.state.neutralG.methods.createEscrow(intvalue, 3600, price, this.symbol, ...
