AI agents are moving real money — and nobody knows who's behind them. Contra is the compliance layer that safeguards every agent: a credential proving there's a real, sanctions-screened human in control — without ever exposing who they are. Verify once; every transaction is covered.
Verify once · privacy-first — no documents, no PII exposed · one line to install
Autonomous agents already pay for compute, APIs, and checkouts — and increasingly act on your behalf. Without proof of a real human in control, that's an open-ended liability. Contra is the compliance layer that closes the gap — and keeps every agent safe to transact.
Agents rack up real spend with no human watching. If something goes wrong, there's no one to point to — and no record of why.
"Who is responsible when an agent moves money?" Today that answer doesn't exist. Contra makes it provable — without exposing personal data.
Protocols, merchants, and other agents need to know an agent is backed by a real, cleared human before they deal with it.
Add the SDK to your agent or app — one line of middleware. No infrastructure to run, no contracts to deploy.
Your user proves they're a real, sanctions-clear human by confirming an account they already have. It takes seconds, and no personal data is ever stored.
From then on, every agent they spawn carries the credential. Any contract reads it on-chain for free — and only authorized regulators can ever request disclosure.
Identity, authority, and transaction risk — the questions that decide whether an agent is safe to deal with, in one privacy-preserving credential your contracts can read.
Proof of a real, cleared human — and the agent acting for them. Verified once, inherited everywhere.
Risk on every transfer, plus the limits and disclosures you control — all without exposing personal data.
When an agent needs to pay, Contra issues a real card in the same transaction — so your agents can transact anywhere, in agentic marketplaces and the everyday web alike. Every charge is gated by the agent's safety credential and checked before it clears. Others are still saying "coming soon." Ours ships.
Knowing who's behind an agent is step one. Contra also proves the agent did its job correctly — every task independently re-checked, backed by real economic stake, with the underlying data never exposed.
An independent operator network stakes real value to validate every task. Dishonest work is slashed, not trusted — so correctness has a cost behind it.
Results are verified with zero-knowledge and notarized-TLS proofs. Correctness is provable on-chain — not taken on faith.
Tasks run inside trusted execution environments (TEE), so an agent's work is validated without ever revealing the data behind it.
Other tools control what an agent can spend. Contra is real compliance — it proves who's behind the agent and makes that proof portable, private, and regulator-ready, so every agent is safe to deal with.
We prove who's behind the agent, not just what it can spend.
Any contract reads the credential directly — no callback to us, no lock-in.
Privacy-preserving credentials. PII is never stored or exposed.
The only permissioned disclosure path — time-bound, logged, anchored on-chain.
Every agent a user spawns inherits the proof automatically.
Adds trust to x402, Stripe ACP & Mastercard Agent Pay — doesn't replace them.
Model Context Protocol — Contra ships a native MCP server.
Agent-native USDC payments, gated per call.
Composable with the Agentic Commerce Protocol.
Card rails for autonomous agents.
Install the SDK, let your users verify once, and every agent they run is compliant and safeguarded — backed by proof of a real human. Be the platform regulators trust.
