Why Colber

Autonomous agents are about to transact with each other at a scale and a frequency humans cannot supervise in the loop. Payment rails are getting good — MoonPay, Coinbase x402, Nevermined are all converging on programmable money for agents. But money alone is not commerce.

The missing layer

Before two agents can transact, they need to trust each other (will the counterparty deliver?), coordinate (what are we agreeing on, exactly?), and persist context (do they remember the last interaction?). On top of that, the operator behind the agent needs observability — a true record of who did what, signed and verifiable.

These are not theoretical concerns. They are the same primitives that took web commerce two decades to consolidate: reputation (Stripe Radar, Trustpilot), negotiation (Stripe Checkout, OpenTable), insurance (Stripe Climate, BoostUp), memory (Algolia, Pinecone), observability (Datadog, Honeycomb). Today no platform ships them as a single, agent-native bundle.

Five primitives, one identity

Colber ships five integrated services — reputation, memory, observability, negotiation, insurance — wired around a common DID:key Ed25519 identity. Each is consumable on its own; together they compose a platform effect that no single-purpose competitor can match.

We chose MCP as the native interface so that any modern agent runtime can use Colber without a custom integration. We chose Apache-2.0 because the protocol of trust for autonomous agents must be open, auditable, and forkable. Vendor lock-in is the worst possible outcome at the layer that decides who can transact with whom.

On-chain, eventually

The v1 platform runs entirely off-chain. Insurance escrow is simulated in Postgres and reputation is anchored to a private append-only log. This is deliberate: we ship value first, then move the trust-critical primitives on-chain (Base L2, USDC) once they are battle-tested off-chain — and only after a third-party security audit (Trail of Bits or OpenZeppelin) approves the contracts.

What we ask

If you are building agents and wish payment rails alone were enough, please try Colber. If they are not enough — and you find yourself reinventing trust, negotiation or observability — open a Discussion. The protocol is yours to shape.
