what's Shade Agents?

Shade Agents are multichain AI-powered smart contracts developed by NEAR Protocol, representing the first truly autonomous AI agents in blockchain. They operate with full onchain verification from source code to transactions, using Trusted Execution Environments (TEEs) for secure execution and chain signatures for cross-chain asset control without custodians or single points of failure. These agents enable verifiable, self-running AI that can trade, sign transactions, and execute intents across chains like NEAR, Ethereum, Solana, and Bitcoin. Built with frameworks like Shade Agent Stack and D-Stack, they support applications such as agentic lending and autonomous businesses, ensuring tamper-proof operations in a decentralized manner.
