SERIES A · LIVE ON SOLANA MAINNET

The Solana settlement layer for AI agents.

Axuon meters every tool call your agents make, scopes their wallet to a single capability, and settles the payment on Solana in under a second. Stripe was built for humans on Visa. We built Axuon for AI agents on Solana.

WHAT IT DOES

Six primitives. One control plane.

Most teams who let their AI agents spend money end up gluing together five vendors and a multisig. Axuon replaces that with a single object model: agents, scopes, tool calls, receipts, disputes. Settled on Solana. That's the surface area.

01 · METER

Pay-per-tool-call at the MCP layer.

Every tool call from your LangGraph / Mastra / Anthropic agent gets stamped at the edge with a deterministic call ID and a price. Works with MCP, A2A, and any HTTP client your agent already speaks.

⎯⎯ ▣ ⎯⎯

02 · AUTHORIZE

Scoped agent wallets, not raw keys.

Each agent gets a Solana keypair bound to a capability scope: "buy under $5 from jupiter.* via SOL/USDC, max 12/hour". Capabilities are signed JWTs, verifiable offline.

▤ → ▥ → ▦

03 · SETTLE

Solana-native, ~400ms finality.

Stablecoin payments (USDC, PYUSD) move on-chain. Sub-cent fees, ~400ms slot time, and Token-2022 confidential transfers when the agent's spend needs to stay private.

◊ ◊ ◊ ◊ ◊

04 · RECEIPT

Counter-signed records, down to the call.

Every tool call settles with a counter-signed receipt anchored to a Solana transaction signature. Replay any call from its call_id — no CSV reconciliation marathon.

▤ ⇌ ▤

05 · GUARD

Real-time risk at agent-speed.

Behavioral baseline per agent wallet. Anomalous spend halts in ~9ms before the Solana tx ever broadcasts. KYC and sanctions baked in.

◉ ⚐ ◉

06 · REPORT

Programmable books, signed and exportable.

Every settled call exports to a Postgres-shaped ledger plus the raw on-chain trail. Stream into Snowflake, Helius webhooks, or your own indexer.

FOUR STEPS · NINE MINUTES

From npm install to settled SPL.

No bizdev call, no enterprise procurement, no rate-card PDF. The first 10,000 tool calls per month are free on devnet for any agent that authenticates with a verified keypair.

Mint an agent wallet

One CLI command generates a Solana keypair bound to a capability scope — not a static API key.

II.

Wrap your agent

One line of middleware in your MCP server / LangGraph / Mastra runtime. Axuon stamps each tool call.

III.

Set a budget

Caps per slot, per merchant, per call type. Hit it and the agent pauses — no production page.

IV.

Get paid

Counterparties settle to your treasury wallet in USDC. Your books reconcile themselves.
