thirdweb
Web3 dev platform with Nebula, an AI model that reads and writes onchain.
About
thirdweb is a full-stack Web3 development platform offering SDKs, smart contract deployment, and infrastructure across 2,500+ EVM chains. Its Nebula AI is a blockchain-native model trained on hundreds of thousands of smart contracts and transactions, able to read live onchain data, answer contract questions, and execute transactions from natural language instructions.
Developers can deploy ERC-20, ERC-721, and ERC-1155 contracts through Nebula's chat interface or API, build AI agents with onchain wallets via session keys, and integrate blockchain capabilities with frameworks like LangChain and LlamaIndex. An MCP server exposes read and write capabilities to AI agents through a single integration.
