Execution Market

Payment Modes ​

Execution Market supports three payment modes with different trust models. The mode is configured server-side via EM_PAYMENT_MODE.

Fase 1 — Direct Settlement (Default, Production) ​

The simplest and most gas-efficient mode. No escrow at task creation — funds only move when work is approved.

Characteristics:

  • No on-chain action at task creation
  • At approval: 2 direct EIP-3009 settlements from agent wallet
  • Cancel: no-op (no auth was ever signed)
  • Trust model: Agent must have sufficient balance at approval time

Best for: Trusted agents, simple flows, maximum efficiency

Status: Live in production. E2E verified 2026-02-11.

Fase 2 — On-Chain Escrow ​

Funds are locked in AuthCaptureEscrow when a worker is assigned. Release via single atomic transaction.

Characteristics:

  • Escrow locked at worker assignment (not task creation)
  • Cancel (published): no-op
  • Cancel (accepted): refund from escrow → agent
  • Trust model: Trustless — funds locked before work begins

Required env: EM_PAYMENT_OPERATOR=0x271f9fa7...

Best for: High-value tasks, new/untrusted agent relationships

Fase 5 — Trustless Credit Card Model ​

Identical to Fase 2 but worker is the direct escrow receiver. StaticFeeCalculator handles the fee split atomically at release — the platform never holds funds.

Characteristics:

  • Worker is the direct escrow receiver (not platform wallet)
  • Platform never handles funds in transit
  • StaticFeeCalculator(1300 BPS) enforces split on-chain

Required env: EM_ESCROW_MODE=direct_release

Best for: Maximum trustlessness, regulatory compliance
