The Problem

AI agents will generate 1M+ payments per second. Current chains can’t clear that.

Stripe’s 2025 Annual Letter identified the core constraint: blockchains need to support 1M–1B transactions per second for the agent economy. At $0.005 gas per call, that’s $432M/day in fees alone.

The answer isn’t a faster chain. It’s a clearinghouse — the same infrastructure that powers every high-volume financial system.

Step 1

The chaos

0

API calls / 5 min

AI agents generate millions of API calls per second. Today, every single one is a separate on-chain transaction — $5,000/sec in gas.

$5,000/sec in gas

Without Stratum

  • ×Every API call = an on-chain transaction
  • ×$5,000/sec in gas fees
  • ×Chain congestion → 35× fee spikes
  • ×Every payment publicly visible
  • ×Single chain dependency
  • ×Single point of failure

With Stratum

  • 1M calls settle as ~20 transfers
  • $0.25/sec in gas fees (99.99% less)
  • Payments clear instantly off-chain
  • Only net settlements visible (private)
  • Works on any chain
  • Facilitator-agnostic

Every high-volume financial system has a clearinghouse.

Visa

150M txns/day

Visa

Doesn’t send 150M bank wires. Nets and batches into a fraction.

DTCC

$2.4Q/year

DTCC

Clears securities without moving the full value. Net settlement only.

Stratum

1M+ payments/sec

Stratum

Compresses to <50 on-chain settlements. The clearinghouse for x402.

The agent economy needs the same infrastructure. Stratum is that infrastructure.

Integration so easy it feels wrong

1 / 3

No blockchain knowledge. No code changes. No SDK. Real endpoint in 30 seconds.

Under the hood

Four cryptographic primitives, composed into a clearing pipeline.

Agent API CallReceiptMerkle TreeSettlement

Cryptographic Receipts

Every payment generates an Ed25519-signed receipt with canonical encoding. Tamper-proof, deterministic, independently verifiable.

Append-Only Merkle Tree

Receipts are stored in an RFC 6962-compliant tree. Inclusion and consistency proofs let anyone verify the full audit trail.

Multilateral Netting

Aggregate net positions across all agents. Greedy matching pairs creditors with debtors to produce the minimum transfer set.

Chain Anchoring

One Merkle root per settlement window, anchored on Solana. The bridge from off-chain clearing to on-chain finality.

For Facilitators

We make you 1,000,000× more efficient

Stratum doesn't replace facilitators — it supercharges them. Instead of processing 500K individual x402 settlements per week, you receive 50 batch instructions.

Trust and verification

Stratum is designed so you don't have to trust Stratum.

1

Trusted

Stratum is trusted to clear correctly. The gateway signs receipts and computes netting. Operators can run their own clearing node for full independence.

  • Receipt signing
  • Netting computation
  • Window management
2

Verified

Every receipt, Merkle proof, and settlement batch is independently verifiable by any third party. Explorer provides real-time verification.

  • Ed25519 signatures
  • Merkle inclusion proofs
  • Consistency proofs
3

On-Chain

Settlement instructions are executed by the facilitator. Merkle roots are anchored on Solana. Finality is on-chain.

  • USDC transfers via facilitator
  • Merkle root anchoring
  • On-chain audit trail
