What Is Concordium (CCD)?

Concordium is an AI infrastructure for the agentic economy powered by a purpose-built, regulatory-grade blockchain with identity and trust built into the protocol.

When an AI agent acts autonomously, the counterparty needs assurance that a verified human authorised it. Concordium delivers that assurance at the infrastructure level. The only platform where verified humans and verified AI agents operate on the same identity layer.

Every account on Concordium, whether a human wallet or an autonomous AI agent, is linked to a verified real-world identity through regulated identity providers. Privacy is preserved through zero-knowledge proofs, allowing users and agents to prove attributes without exposing personal data.

The Concordium Agent Registry is ERC-8004-compatible, enabling AI agents to register on-chain with a verified human or entity behind them. The Verified by Concordium badge certifies agents across Ethereum, Solana, and third-party ecosystems. x402 enables pay-per-call agent payments. Protocol-Level Locks provide trustless custody at the protocol layer, not in smart contracts. Sponsored Transactions allow agents to operate and use native stablecoins without holding CCD.

Any agent on any chain can call Concordium’s identity and compliance layer via MCP or A2A. The enterprise compliance stack includes KYC, multi-party ID disclosure, and Verify & Access for regulated credential verification.

Designed by world-renowned cryptographers and trusted by enterprises, agent networks, and developers worldwide.

What Makes Concordium Unique?

• Protocol-Level Identity for Humans and AI Agents: Every account on Concordium is linked to a verified real-world identity. User privacy is preserved through zero-knowledge proofs: users and agents prove attributes (age, residency, accreditation) without exposing personal data. • Agent Identity & Registry: Concordium’s ERC-8004-compatible Agent Registry allows AI agents to register on-chain with a verified human or entity behind them. The Verified by Concordium Badge certifies agents operating across Ethereum, Solana, and third-party ecosystems, carrying trust into any environment. • Agent Payment Infrastructure: x402 enables pay-per-call HTTP payments for agent-to-agent and agent-to-service transactions. Protocol-Level Locks (PLL) provide trustless escrow and custody at the protocol layer, not in smart contracts, eliminating honey-pot risk. Sponsored Transactions allow agents to operate without having to pay for fees, while using native stablecoins to settle transactions. • Cross-Chain Trust-as-a-Service: Any agent on any chain can call Concordium’s identity and compliance layer via MCP (Model Context Protocol) or A2A (Agent-to-Agent), with no codebase rewrite required. • Enterprise Compliance Stack: KYC, multi-party ID disclosure under court order with threshold decryption, and ZKP-powered credential verification in regulated industries. • Performance: ConcordiumBFT consensus with approximately 2,000 TPS and 2–4 second finality. Transaction fees referenced against a fiat benchmark (EUR) for cost predictability.

Predictable, Fiat-Referenced Transaction Fees Concordium implements transaction costs referenced to fiat currency (EUR). While fees are paid in CCD, the required amount adjusts based on the token’s market price, providing stable, predictable costs regardless of market volatility. For agent-to-agent transactions, Sponsored Transactions can eliminate fees entirely for the end user or agent, allowing for feeless native stablecoin transactions.

What is the role of the CCD token?

CCD is Concordium’s native utility token. It plays a central role in the ecosystem: • Agent and user transaction fees: Payment for transfers, smart contract calls, agent registry operations, and protocol-level token transactions. Fees are referenced in EUR for predictability. Sponsored Transactions allow CCD holders to subsidise gasless agent operations like native stablecoin transactions. • Staking: Validators and delegators stake CCD to secure the network via Proof-of-Stake consensus and earn protocol rewards. • Governance: CCD holders participate in network governance, including election of Governance Committee members and protocol proposals under the decentralisation roadmap. • Medium of exchange: Used for payments and commercial transactions across the Concordium network, including agent-to-agent settlement.

Where can you buy CCD?

Concordium (CCD) tokens can be purchased on several exchanges, such as Kraken, Kucoin, Gate.io, and Uphold.
