Swapexacttokensfortokens Deadline, ExactInputSingleParams I am us

Swapexacttokensfortokens Deadline, ExactInputSingleParams I am using the method: swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline). 检查 swapExactTokensForTokens() 的代码，以更好地理解如何执行这些操作。 具体的には基本的なswapの種類の説明と、swapExactTokensForTokensに対して内部実装の解説です。 誤っている点があったらコメントを頂けると嬉しいです。 またPancakeSwapはUniswap v2のフォークなので事実上Uniswap v2の説明となります。 function swapExactTokensForTokens (uint amountIn,uint amountOutMin,address [] calldata path,address to,uint deadline) external returns (uint [] memory amounts); uint deadline // 过期时间 )external virtual override ensure (deadline) returns ( uint[] memory amounts // 交易期望数量列表 ){ } 函数 swapTokensForExactETH 和 函数 swapExactETHForTokens 相比，仅交换了一下代币的交易顺序，执行逻辑还是差不多的。 实现分析 This guide will demonstrate how to swap tokens on Uniswap V2 using JavaScript and the Ethers. In the linked transaction, you passed 1637842091 as the value of deadline, 'function swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory amounts)', 'function swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline)', 'function swapExactETHForTokens(uint amountOutMin, address[] calldata path, address to, uint deadline) external payable returns (uint[] memory amounts)', I've read almost every question on here referencing uniswapv2 swapExactTokensForTokens and I'm still getting the same error (below). pancakeSwapRouter, [ 'function getAmountsOut(uint amountIn, address[] memory path) public view returns (uint[] memory amounts)', 'function swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory address[] memory path, address to, uint256 deadline) internal { quickSwapRouter. Because routers are stateless and do not hold token balances, they can be replaced safely and trustlessly, if necessary. Uniswap v2 router code walkthrough The Router contracts provide a user-facing smart contract for safely minting and burning LP tokens (adding and removing 0 I think I see an issue here. Specifically, I encounter errors when using the swapExactETHForTokens and swapExactTokensForETH I want to write a swapping processor to be able to swap tokens on different Dexes. swapExactTokensForTokens ( amountIn, amountOutMin, [token Uniswap-v2コントラクトの仕組み、 コントラクトの書き方について 通常、プールコントラクトの計算では小数を使いますが、 EVMで小数はサポートされていません。 そこで、Uniswapが考えた解決策は、224ビット値を使用することです。整数部分に112 ビット、小数部分に112ビットを使います つ As far as the pair doesn't have wbnb I use swapExactTokensForTokens (meanwhile WBNB -> BUSD with swapExactETHForTokens works well) Preparing transaction call and trying to estimate gas beforehand, but it fails with 'function swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory amounts)' require(deadline >= block. UniswapV2Router02 is deployed at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on the Ethereum mainnet, and the Ropsten, UniswapV2の有名な数理モデル x y = k x ⋅y = k をそもそもどう使うのか、 結局どこのコントラクトに実装されているのかというところでした。 uint deadline = block. function Found 1 function(s) with the name `swapExactTokensForTokens`: ['swapExactTokensForTokens(uint256,uint256,address[],address,uint256)'] Function invocation failed due to no matching argument types.
