Protocol-level identity for AI agents now extends to Solana. Anchor your Solana keys to a verified human or business, with no migration required.
You built your agent on Solana. It's fast, it's cheap, it's already transacting. What it can't do is prove who's behind it.
When the Agent Registry launched, the Verified by Concordium Badge was built to travel to any supported chain. Solana is the next one. If your agent runs on Solana, it can now anchor to a verified human or business through the same registry that Ethereum agents already use. The chain it runs on does not change. What changes is that anyone it deals with knows that there is a verified human behind it.
Why Solana
Solana has become the busiest environment for autonomous agents. Through the first quarter of 2026, activity there moved from experimentation to real economic output, drawn by sub-second finality and fees low enough for machines to transact constantly.
It is the only major ecosystem that supports both the x402 standard and Stripe's Machine Payments Protocol, the rails agents use to pay for services without a human approving each transaction.
That activity is also the problem. Agents on Solana are buying API access, settling payments, and transacting with other agents at machine speed, yet none of that infrastructure answers a basic question: who is accountable for what an agent does.
And unlike Ethereum, Solana has no equivalent of ERC-8004, no agent identity standard at all. The accountability gap isn't just unsolved here. The first layer of it was never built. That makes the question of who stands behind an agent more important on Solana than anywhere else.
How It Works on Solana
The Verified by Concordium Keys (VCK) registry now accepts Solana keys natively. The flow is the same one Ethereum agents already use. You register your agent through the Agent Registry DApp or API. Your agent's Solana keys are linked to a Concordium account through the VCK registry. That account is tied to a verified identity through the protocol-level ID infrastructure that has been in production since Concordium's mainnet launched on 9 June 2021. Zero-Knowledge Proofs establish the link without exposing any personal data.
Your agent then receives the badge, verifiable on-chain, visible in explorers, and machine-readable through Concordium's MCP server, so another agent can check it before deciding to transact.
Your agent stays on Solana. It touches Concordium once, to anchor its identity, and the badge is the proof that follows it from there.
Why This Matters Now
On Solana, real value is already moving through autonomous agents at machine frequency. Since x402 launched on the chain it has processed more than 35 million transactions and over $10 million in volume, figures that are still early but growing, yet counterparties have no standard way to know who deployed the agent moving that value.
The accountability pressures are no different from Ethereum's: the EU AI Act is law, and running on Solana does not exempt an agent from a jurisdiction that asks who is behind it. What is distinct is the scale of agent-to-agent commerce, where one Solana agent transacts with another and no human is present to judge trust. Concordium's MCP server lets an agent check, before it acts, whether its counterparty carries a Verified by Concordium Badge and what that badge guarantees.
The Badge Was Built to Travel
The promise at launch was that the badge would work for any agent, on any supported chain, from any supported framework. Solana is that promise in practice.
An agent on Ethereum and an agent on Solana can now carry the same mark, backed by the same verified identity, recognised by the same MCP server. What matters is not the chain underneath but the accountability that now sits on top of it.
This week marks five years since that mainnet launch. The verified identity behind the badge has secured the network since day one, and Solana is the latest ecosystem it reaches.
Agents have been anchoring to the Registry almost every day since it opened in late May, and Solana keys join that same record.
A Solana agent that anchors today proves who stands behind it to every counterparty it meets, without ever exposing the human or business doing the standing.
Register your Solana agent through the Agent Registry and claim the Verified by Concordium badge.
Verified Humans. Verified Agents. One Protocol.
