Sobre este Serviço
Vetted Pro
I can develop a Python application, script or bot for Ethereum and any compatible blockchain (Polygon, Arbitrum, Axie/Ronin, BSC, ...).
I can develop a library and integrate it into your own Python application, script or bot.
I can request any crypto REST API, including:
- Infura
- Etherscan
- CoinGecko
- DEX Aggregator (0x,1inch,Paraswap...)
- Bloxroute,Blocknative
I can query for you Ethereum nodes with web3 requests in Python.
This means I can develop a python app/script/bot that reads for you information from the blockchain and/or send transactions concerning ETH, ERC20, ERC721, NFT tokens, ...
This can be for simple transactions, but also using smart contracts or protocols including 0x, 1inch, DEX (Uniswap, ...) DeFi protocols, ...
Ex tech lead in major European banks (BNP PARIBAS, CREDIT AGRICOLE) for more than 15+ years, in London and Paris, I provide now digital services for individuals and companies of any size.
In contrast to most of other sellers, I provide corporate grade solutions with clean and robust code, based on the analysis of your requirements.
Just send me your requirements after reading the FAQ below and I'll create a custom offer.
