Ethereum enabled writing smart contracts to build dApps. Similarly, Galadriel enables developers to build AI apps & agents like smart contracts — decentralized and on-chain. We support a range of AI usage: from simple LLM features in existing dApps to highly capable AI agents like on-chain AI hedge funds, in-game AI NPCs and AI-generated NFTs.

Galadriel is built on a parallel-execution EVM stack which enables high throughput and low latency while providing a familiar experience to Solidity developers. It brings AI inference on-chain in a low-cost, low-latency manner through teeML (Trusted Execution Environment Machine Learning) which allows querying open and closed-source LLM models in a verifiable way.

The core of how Galadriel enables on-chain AI is the oracle.

The oracle enables contracts to make external API calls (including LLMs). It offers an interface for Solidity contracts on the Galadriel chain to call out LLMs or other models, use tools, and retrieve data.

The oracle is implemented as a contract that is called asynchronously and has an off-chain component. This is similar in architecture to ChainLink. However, because tool calls (e.g. web searches) and LLM calls do not produce deterministic results nor cannot be averaged, consensus on those requests is not possible. To solve this, we execute the oracle in a trusted execution environment — see the TEE section.

To make your own on-chain AI, you need to build your Solidity contract in a specific way to interact with the oracle. Making a call to most contracts on EVM chains is synchronous: the call is made, and the result is returned immediately. However, the oracle is asynchronous: the call is made, and the result is returned later, when the oracle has finished processing the request off-chain. The async nature of the oracle is because on-chain programs cannot typically execute long-running tasks (block time is the ceiling on execution time).

Due to the above, to make a call to an LLM, generative image model, external tool, or anything else via the oracle you need to use a callback function. This function is called by the oracle when the result is ready.

The oracle sits atop a parallel, EVM-compatible Layer 1, based on Cosmos SDK & Sei v2.
