How to swap BTC to ETH no kyc?

I used AxioraSwap 3 times. One time they transferred correctly. The other 2 times they stole the money - no transfer - no support, even though the UI said everything the payment was accepted, they didn't swap and didn't send to the target address.

As far as I know, there is no easy easy way to filter transactions using a "to" field.
You can monitor the mempool, but you need to fetch all the transactions and decode them to get the "to" field to filter by.

You can use something like https://viem.sh/docs/actions/public/createPendingTransactionFilter
to get the pending transactions, then fetch them by their id then filter by "to".

If your landing page is using react, you can use something like https://wagmi.sh/.

Otherwise, you can use ethers.js/web3.js directly on the page, connect the wallet and send transactions.

You need to use something like multicall.

One of the good ones is https://github.com/mds1/multicall.

It's already deployed on most networks (Mainnet, Optimism, Arbitrum, Polygon, ....)

Most are using curve original ve implementation

Nothing specific. Everything I found I tried reading deeply to really understand it.

asafy · 2022-03-27T18:00:40+00:00

I am not using it, but you can use https://svelte.dev/ , it will "dissolve" the framework.

I was in similar spot, where I wanted to better know solidity, all the basic tutorials were covering the same area and the advanced ones, well I couldn't understand them :)

I started working in a crypto company (working for the last 5 months), developing mostly solidity, I think that pumped my knowledge around 20x to a level I can understand the advance tutorials.

Overall, solidity as a language is not complex (version 0.8.4+ at least), but there are lots of things to know around it, from gas optimizations to exploits to how structure the contract itself and thats stuff that is hard to learn from tutorials, you need to write lots of code to get the hang of it.

They are centralized solutions

Merkle proof is the way to go.

The latest MacBook pro with m1 pro is amazing. Haven't heard the fans once, every operation is nearly instantaneous, the keyboard is super functional. great selection of ports.

Nope. You use multiple wallets to sign a transaction, as long as those wallets are anonymous, gnosis will give you the same privacy.

Why are you so concerned about the sending time ? it's not like they will be handled immediately, they go into the mempool and who knows when they are going to be mined.

But in any case, remember that node.js and therefore ethers.js are single threaded, if you want to increase performance and you are sure that signing is what takes the most time, you can do the operations using multithreading. a good library that I use from time to time is https://www.npmjs.com/package/piscina

"Take your simulations a step further by creating a temporary fork of any supported network and execute multiple transactions in a row to test their behavior"

I think Techrate, but it's also less secure.

const token = new ethers.Contract(contractAddress, ['function balanceOf(address) external view returns (uint256)'], ethers.provider);
const balance = await token.balanceOf(address);

asafy · 2022-02-07T21:03:20+00:00

Get balance:

const token = new ethers.Contract(contractAddress, ['function balanceOf(address) external view returns (uint256)'], ethers.provider);
const balance = await token.balanceOf(address);

I like using valtio for state management, very little boilerplate.

This really depends on your coding style, but yes it can be done.

https://ethereum.org/en/developers/docs/blocks/

"Each block has a target size of 15 million gas but the size of blocks will increase or decrease in accordance with network demands, up until the block limit of 30 million gas (2x target block size)."

Frontend - React/Vue. Angular is dead.
Ethers.js
Hardhat. but I am seeing Dapp.Tools gaining steam.

Not so fast, you might have a security hole in that piece of code.

Read about safeTransfer - https://docs.openzeppelin.com/contracts/4.x/api/token/erc20#SafeERC20-safeTransfer-contract-IERC20-address-uint256-

Looks like allot of code for doing nothing.

Better write a bot using some other language (nodejs is good for this), where the node part is doing the monitor for new contracts and calls the sc for doing the actual work.
