教你一招 如何批量发送eth 或者代币

批量发送以太坊 部署下面的合约 然后往下面的合约打币 就可以分发

1. pragma solidity ^0.4.21;
2.  
3. contract batchTransfer {
4.  
5. address[] public myAddresses = [
6.  
7. 0xcD2CAaae37354B7549aC7C526eDC432681821bbb,
8.  
9. 0x8948e4b00deb0a5adb909f4dc5789d20d0851d71,
10.  
11. 0xce82cf84558add0eff5ecfb3de63ff75df59ace0,
12.  
13. 0xa732e7665ff54ba63ae40e67fac9f23ecd0b1223,
14.  
15. 0x445b660236c39f5bc98bc49dddc7cf1f246a40ab,
16.  
17. 0x60e31b8b79bd92302fe452242ea6f7672a77a80f
18.  
19. ];
20.  
21.  
22.  
23. function () public payable {
24.  
25. require(myAddresses.length>0);
26.  
27. uint256 distr = msg.value/myAddresses.length;
28.  
29. for(uint256 i=0;i<myAddresses.length;i++)
30.  
31. {
32.  
33. myAddresses[i].transfer(distr);
34.  
35. }
36.  
37. }
38.  
39. }

批量发送代币 发布一下合约 即可实现

1. pragma solidity ^0.4.0;
2.  
3. contract demo{
4.     
5.     function transfer(address from,address caddress,address[] _tos,uint v)public returns (bool){
6.         require(_tos.length > 0);
7.         bytes4 id=bytes4(keccak256("transferFrom(address,address,uint256)"));
8.         for(uint i=0;i<_tos.length;i++){
9.             caddress.call(id,from,_tos[i],v);
10.         }
11.         return true;
12.     }
13. }
