问题分析与解决方案
错误实现2的核心问题
从ABI和合约源码可知，buyPlot仅接受单个coord参数，但实现2传入了row1、column1两个参数+overrides，参数数量不匹配，直接触发no matching fragment错误。
错误实现1的核心问题
实现1仅传入了coord参数，但未附带ETH金额，合约要求msg.value >= plotPrice，交易因金额不足被revert；missing revert data通常是节点未返回具体revert原因，但本质是交易不符合合约规则。
正确实现步骤
- 将row和col转换为单个coord值：合约用单个uint256类型的
coord标识地块位置，需根据合约isValidCoord的规则编码（例如coord = row * 网格宽度 + col，需替换为实际网格宽度）。 - 获取地块实时价格：调用合约
price(coord)函数获取当前价格，不要自行计算——价格会随purchaseCount动态翻倍（plotPrice = BASE_PRICE << plot.purchaseCount）。 - 附带正确ETH金额调用：通过overrides传入
value参数，值为获取到的plotPrice。
正确代码示例
const buyPixel = async (row: number, col: number) => { const { gridContract: contract } = getEthers(); try { // 1. 根据网格规则计算coord，此处假设网格宽度为100，需替换为实际值 const gridWidth = 100; const coord = BigInt(row * gridWidth + col); // 2. 获取该地块的当前价格 const plotPrice = await contract.price(coord); // 3. 调用buyPlot并附带对应ETH const overrides = { value: plotPrice }; const tx = await contract.buyPlot(coord, overrides); await tx.wait(); console.log("交易成功:", tx.hash); } catch (err) { console.error("Error buying pixel:", err); } }
额外注意事项
- 确认
isValidCoord修饰器的规则，确保计算出的coord合法，否则会触发revert。 - 若仍出现
missing revert data，可尝试更换Mantle测试网节点，或手动指定gasLimit关闭自动gas估算，但优先保证交易参数正确。
