Izidingo Zokuqala

Udinga i-Node.js 18 noma entsha ngoba iphrojekthi idinga ukusebenza kwe-fetch okwakhelwe ngaphakathi. I-README iphinde ibhale i-npm 9 noma entsha. Uzodinga i-endpoint ye-RPC ye-Ethereum Mainnet, ukhiye oyimfihlo wesikhwama, kanye ne-ETH eyanele ukukhokhela noma yikuphi ukuthunyelwa noma ukuthengiselana kokubhala okuqinisekisayo.

Faka Iphrojekthi

1. Clone indawo yokugcina

Clone iphrojekthi bese ushintshela kumkhombandlela wayo. Faka esikhundleni sendlela yendawo yokugcina ngendawo oyisebenzisayo.

git clone https://github.com/yoge7388095s/eth-trading-bot
cd <your-repo>

Ungakwazi futhi ukulanda indawo yokugcina njengefayela le-ZIP bese uyikhiphela kufolda esendaweni.

2. Faka okuncikile

Faka amaphakheji achazwe ku-package.json:

npm install

Lokhu kufaka okuncikile okubili okuyinhloko:

• ethers yabahlinzeki, izikhwama, ukuphathwa kwe-ABI, nokuthengiselana.
• solc yokuhlanganisa i-Solidity kusuka ku-Node.js.

Ngemva kokufaka, iphrojekthi kufanele ibe nomkhombandlela we-node_modules. Uma ungekho, hlola okukhiphayo kwe-npm install bese ulungisa iphutha lokufaka ngaphambi kokuqhubeka.

Hlela Isikhwama Noxhumano lwe-RPC

Dala ifayela elibizwa ngokuthi .env empandeni yephrojekthi. Faka ukhiye wakho oyimfihlo ne-URL ye-RPC ye-Ethereum Mainnet:

PRIVATE_KEY=0xYourPrivateKey
RPC_URL=https://ethereum-rpc.publicnode.com

I-README ibala lawa ma-endpoint e-RPC ayisibonelo:

• https://ethereum-rpc.publicnode.com
• https://eth.llamarpc.com
• https://cloudflare-eth.com
• https://mainnet.infura.io/v3/<KEY>
• https://eth-mainnet.g.alchemy.com/v2/<KEY>

Gcina .env iyimfihlo futhi uqinisekise ukuthi ifakiwe ku-.gitignore. Ifayela liqukethe imininingwane yokungena okungafanele neze ithunyelwe endaweni yokugcina yomphakathi.

Qalisa I-Deployer Esebenzisanayo

Qalisa isixhumi esibonakalayo esiyinhloko ngalo myalo:

node start

Uma iphrojekthi ichaza iskripthi sokuqala se-npm, ungasebenzisa futhi:

npm start

Uhlelo luhlola inethiwekhi, isikhwama, nebhalansi, bese luvula imenyu yalo esebenzisanayo. Imenu evamile ingaba nezinketho ezifana nalezi:

=== Ethereum Contract Deployer ===

i Network: mainnet (chainId 1)
i Wallet:  0x8c27...66CdC
i Balance: 0.5 ETH
! THIS IS MAINNET - transactions cost real money!

Main menu
> Deploy Arbitrage.sol
  Open deployed Arbitrage (0x2d7A..., 2025-01-15)
  Exit

Sebenzisa izinkinobho zemicibisholo ukukhetha into, cindezela u-Enter ukuqinisekisa ukukhetha, bese usebenzisa izilawuli ezibonisiwe ze-OK noma ze-Cancel lapho uhlelo lucela ukugunyazwa kokuthengiselana. Cindezela Ctrl+C ukuze uphume.

Hlanganisa Futhi Uthumele Inkontileka ye-Solidity

1. Faka noma khetha ifayela le-Solidity

Beka ifayela le-Solidity kumkhombandlela wephrojekthi, noma khetha ifayela elikhona le-.sol ngemenyu yokuthumela. Umhlanganisi wakha inkontileka ngokusekelwe egameni lefayela layo futhi uthola ama-import asekelwayo ngokuzenzakalelayo.

2. Buyekeza imininingwane yokuhlanganisa nokuthumela

Khetha Deploy <file>.sol kumenyu eyinhloko. Uhlelo luhlanganisa inkontileka, lulungiselela ukuthengiselana kokuthumela, bese lubonisa izidingo zayo zegesi ngaphambi kokucela ukuqinisekiswa.

3. Qinisekisa ukuthengiselana

Buyekeza isilinganiso segesi, imali yamanje, imali ephezulu, ibhalansi yesikhwama, nemininingwane yenkontileka. Qinisekisa kuphela lapho amanani nenethiwekhi okuqondiswe kuyo kulungile. Ngemva kokuba ukuthengiselana sekufakwe ku-blockchain, ithuluzi libonisa ikheli elithunyelwe nesixhumanisi se-Etherscan.

Ulwazi lokuthumela lugcinwa endaweni ku-deployments.json. Lokhu kukuvumela ukuthi uvule kabusha inkontileka ethunyelwe kamuva ngaphandle kokuphinda ufake ikheli ne-ABI yayo.

Qonda Ukuboniswa Kwangaphambili Kwegesi

Ngaphambi kokuthumela nangaphambi kwemisebenzi yokubhala esekelwayo, ithuluzi libonisa ukubuka kuqala kwegesi. Ukubalwa kwalo kulandela inqubo ebhalwe ku-README:

1. estimateGas inikeza isilinganiso semfuneko yegesi.
2. Umkhawulo wegesi ubalwa njengesilinganiso kanye ne-buffer engu-10%.
3. Imali ephezulu ngegesi ibalwa ngokuphindwe kabili kwemali eyisisekelo kanye nemali yokubeka phambili.
4. Isixhumi esibonakalayo sibonisa kokubili imali elindelekile ye-block yamanje kanye nemali ephezulu engenzeka.
5. Isilinganiso se-Chainlink ETH/USD sisetshenziselwa ukulinganisa imali ngamadola.

Ukubuka kuqala kungafaka amanani afana namayunithi egesi alinganisiwe, umkhawulo wegesi, imali eyisisekelo, imali yokubeka kuqala, imali ephezulu ngegesi ngayinye, izindleko ezilindelekile ze-ETH, izindleko eziphezulu ze-ETH, kanye nebhalansi yesikhwama semali. Phatha imali ephezulu njengokulinganisa okuphezulu futhi uqinisekise ukuthi ibhalansi yakho ingakhokhela umsebenzi.

Vula Ukuthunyelwa Okulondoloziwe bese Ubiza Imisebenzi

Khetha Open deployed <name> ukuze usebenze nenkontileka eyake yalondolozwa ku-deployments.json. Isixhumi esibonakalayo sibeka amalebula emisebenzini etholakalayo ngokuziphatha kwayo:

• [read] ikhomba imisebenzi ye-view ne-pure engathumeli ukuthengiselana.
• [write] ikhomba imisebenzi eshintsha isimo edinga ukuthengiselana.
• [payable] ikhomba imisebenzi engamukela i-ETH.
• [info] Contract balance ibonisa ibhalansi yenkontileka.
• <- Back to main menu ibuyela kumenyu enkulu.

Izingcingo zokufunda kuphela zingasetshenziswa ukuhlola isimo senkontileka. Izingcingo ze-write ne-payable zidlula ekubukweni kuqala kwegesi futhi zidinga ukuqinisekiswa ngaphambi kokuthunyelwa kokuthengiselana. Isixhumi esibonakalayo sinikeza nesenzo se-OK ukuze ukhansele esikhundleni sokuthumela umsebenzi.

Qalisa i-Mempool Stream

I-mempool stream isebenza njengenqubo ehlukile. Yiqale mathupha ngo:

node mempool.js

I-stream ifometha umsebenzi otholiwe ngemininingwane efana nomthengi, i-router, inani le-ETH, ithokheni, indlela, i-ID yokuthengiselana, kanye nombiko wesimo ovelayo. I-README iphinde ibonise imibukiso yesivumelwano nenzuzo yokugeleza komsebenzi okusekelwa yi-stream.

Umthombo wamathokheni yi-erc20.json, elandela ifomethi ye-Uniswap Token List Schema evela ku-Sequence Token Directory. I-loader isekela uhlu lwamathokheni olungenalutho noma into equkethe uhlu lwe-tokens. Ihlunga amakheli angavumelekile namakheli aziro, igcine amathokheni ane-chainId elingana no-1, bese ikhipha ikheli, uphawu, negama lethokheni ngayinye.

Uma i-erc20.json ingekho, i-stream ibuyela kumakheli angahleliwe futhi ibonise isexwayiso. Misa i-stream ngo-Ctrl+C, noma usebenzise inketho yokumisa lapho ivela kusixhumi esibonakalayo esisebenzisanayo.

Sebenzisa Ama-Import e-Solidity

I-compiler eyakhelwe ngaphakathi isekela izindlela eziningana zokungenisa:

• Ama-URL e-GitHub, afana ne-import "https://github.com/Uniswap/v3-core/...";
• Ama-import e-CDN esitayela se-npm, afana ne-import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
• Amaphakheji atholakala ku-node_modules yasendaweni.
• Ama-import asendaweni ahlobene, afana ne-import "./MyLib.sol";

Izixhumanisi ze-GitHub ezisebenzisa ifomethi ethi github.com/owner/repo/blob/branch/path ziguqulwa ngokuzenzakalelayo zibe ifomethi ehambisanayo ye-raw.githubusercontent.com.
