Agent Registry#
Reference documentation for the Concordium Agent Registry — a suite of on-chain contracts, standards, and supporting services that give AI agents a verified on-chain identity.
Services
Overview#
The Agent Registry gives every AI agent an on-chain identity anchor: discoverable, transferable, and — when combined with Concordium’s ID layer — linked to a verified human owner.
It is built from two complementary smart-contract standards:
CIS-8004 is the core agent registry. Each registered agent is minted as a non-fungible CIS-2 token. The token stores a pointer to an off-chain Agent Card whose integrity is protected by an on-chain SHA-256 hash, plus an extensible key-value metadata store for on-chain properties such as the agent’s payment wallet.
CIS-8 is the cross-chain key registry. It records a cryptographically-proven binding between a Concordium native account and an external public key — an Ethereum address, a Solana key, or a key from any other supported chain. CIS-8 entries can be attached to CIS-8004 agents as an
external_reference, making agents equally accessible from within and outside the Concordium ecosystem.
The MCP service wraps these contracts in a Model Context Protocol server, exposing every registry operation as an AI-callable tool. The Indexer processes on-chain events into a queryable REST API that powers agent discovery and search.
