Base Level Locks
Create, fund, draw down, and cancel. All operations are authorised by the protocol itself. Funds can only move to pre-defined destinations.
Agent-to-Agent Settlement
Agentic transactions are breaking down because smart contracts were built for human-supervised transactions, not autonomous ones.
Concordium fixes this at the infrastructurel level, using cryptographic credentials and zero-knowledge proofs to link every agent to an accountable human or entity while keeping that identity private.
The Problems with Smart Contracts
Custodial Risk
Funds sitting in a smart contract are funds exposed. A bug or hack can drain them entirely. Agents shouldn’t have direct access to funds, only release or cancel a locked amount.
No Bounded Failure
When a smart contract is compromised, the blast radius is unlimited. Every user of that contract is affected.
Not Built For Autonomy
Smart contracts assume a predetermined path. Agents operating unsupervised act dynamically, as opposed to the strict rules of a smart contract.
Agent-to-Agent Settlement vs Smart Contracts
Smart Contracts | Protocol-Level Locks | |
|---|---|---|
Custody model | Funds held by the contract | Funds stay in user custody, ring fenced by the protocol |
Failure risk | A single exploit can drain every user | Bounded by design, no honeypot to attack |
Control boundaries | Defined in contract code, enforced by code | Enforced by the protocol itself, with optional contract logic on top |
Suitability for autonomous agents | Designed for pre-deterministic flows | Built for continuous, dynamic agent activity |
Protocol-Level Locks (PLL)
Hold funds in protocol-enforced escrow supported by three pillars.
Enhanced Locks
Layer business logic on top via smart contracts: spending limits, daily allowances, counterparty restrictions, time-based conditions.
Secure by Design
Funds never leave your custody. It’s the combination of base level locks and enhanced locks that shield the funds from chain level threats and rogue agents.
How Agent-to-Agent Settlement Works
Every agent payment on Concordium follows the same flow, with two possible outcomes at the end.
Agent initiates.
The agent acts on behalf of its verified principal, within an authorised scope.
01
Conditions set.
Spending limits, approved counterparties, and delivery requirements are attached to the transaction.
02
Funds locked.
The amount is ring-fenced in a Protocol-Level Lock. Custody stays with the principal.
03
Counterparty acts.
The counterparty either delivers against the agreed conditions or fails to.
04
Settlement resolves.
If conditions are met, funds are released to the counterparty. If not, funds return to the principal. No honeypot, no recovery process.
05
The Commerce Rail for Autonomous Agents
Protocol-Level Locks are what make unsupervised agent payments viable. Combined with sponsored transactions and x402 integration, Concordium becomes the settlement layer agents choose.
Settlement That Agents Can Trust

Frequently Asked Questions
What is agent-to-agent settlement?
.svg)
The process by which two autonomous agents exchange value on-chain without a human approving each transaction. It requires a settlement layer that can hold funds, enforce conditions, and resolve outcomes without supervision.
How is agent-to-agent settlement different from payments?
Payments move value from A to B once a verified human has authorised the transfer. Agent-to-agent settlement moves value automatically between agents acting under pre-set rules, which means the infrastructure has to enforce those rules at the protocol level rather than rely on human checks.
Why don't smart contracts work for autonomous agents?
Smart contracts hold custody of funds, which turns every contract into a honeypot exposed to a single exploit.
How do agents settle transactions securely?
Through Protocol-Level Locks that ring-fence funds in protocol-enforced escrow rather than handing custody to a contract. Funds stay with the principal, release only when conditions are met, and revert automatically if they are not.
What infrastructure is needed for agent economies?
Three layers working together: verified identity so counterparties know who is transacting, protocol-level settlement so funds are never exposed in honeypots, and compliance-ready rails so regulators can audit when required. Concordium provides all three at the base layer rather than as application-level add-ons.
How do AI agents pay each other?
On Concordium, an agent pays another by locking funds in a Protocol-Level Lock that releasesonly when the agreed conditions are met. Custody stays with the verified human principal, andevery payment is tied to an accountable identity. x402 and Sponsored Transactions handle theflow, so agents can transact without holding CCD.
How does x402 enable agent-to-agent payments?
x402 is an HTTP-native method that lets agents pay per call for services. On Concordium it runswith verified identity built in, so every x402 settlement traces back to an accountable entity.Combined with Protocol-Level Locks, agents can pay autonomously while funds stay protected.
What is agentic commerce?
Agentic commerce is autonomous agents discovering, negotiating, and settling transactions onbehalf of people and businesses. It needs two things general-purpose chains lack: a way toknow who is behind each agent, and a way to settle value without exposing funds. Concordium provides both, with verified identity and Protocol-Level Locks.
