Platform overview

From API call to settled
transaction in 5 seconds

Velarum is a non-custodial Permission Layer. Your AI agents create PaymentIntents under user-defined AgentAuthorizations; users sign in their own wallets; Velarum never holds keys, never signs, never broadcasts.

1

Register Agent metadata โ€” keys stay with the user

You register an Agent on Velarum (name, owner, scope). Keys live in your wallet, smart account, or chosen external custodian โ€” never on Velarum. Velarum only stores the agent record and the user-provided payer address.

POST /v1/agents
โ†’ { agent_id, owner_org_id }
2

Set spend policies

Define per-agent daily limits, allowlisted destinations, and HC-NC-5 thresholds (per-tx max / cumulative cap / active window / whitelist). Your policy โ€” not Velarum โ€” is what blocks any intent that violates it. Velarum surfaces the block client-side and you still sign every allowed intent yourself.

POST /v1/policies
โ†’ { max_daily_usdc: 500 }
3

Send & receive funds โ€” you sign, we never do

Your agent posts a payment intent. Velarum validates it against your policy and returns an unsigned Stellar transaction. Your SDK signs it locally with your key and broadcasts to Stellar. Velarum never holds or touches a private key.

POST /v1/intents
โ†’ { unsigned_tx }
sdk.sign_and_broadcast(unsigned_tx)
โ†’ { tx_hash, settled_at }
