  • Computes multilateral netting (1,000 payments → ~10 transfers)
  • Builds Merkle proof tree (RFC 6962)
  • Anchors Merkle root on Solana mainnet
  • Produces TEE attestation per settlement window (Intel TDX on Phala Cloud)
  • Executes USDC transfers to your service wallets
  • Supports Solana and Base

Advanced: Custom settlement flows

For custom settlement workflows, Stratum also supports:

  • Webhook API — register a webhook to receive settlement batches and execute transfers yourself
  • Settlement Dashboard — settle batches manually using your Phantom wallet at /dashboard
  • Polling API — poll GET /v1/settle/pending for pending batches
