Escrow protection for agent payments on Base — USDC held in smart contract until job completion.

概覽

AI 產生的概覽

讓助理在 Base 上發起並釋出由智慧合約託管的 USDC 付款，直到工作完成。

可以做什麼
Paycrow 為代理付款提供託管保護：USDC 由智慧合約持有，直到工作完成後才釋出，運作於 Base 網路。它同時提供遠端端點，以及透過 stdio 執行的本機 npm 套件。未公布工具清單，因此具體操作在此無法說明。
適用情境
當助理需要為他人完成的工作付款，並希望款項在工作完成前被鎖定、而非預先支付時，可以考慮使用。對於不需要託管的普通付款沒有幫助。
執行需求
需要連線遠端端點，或在本機安裝 Node.js 執行環境，以透過 stdio 執行該 npm 套件。未宣告任何身分驗證、環境變數或標頭。
安裝前請注意
它會在 Base 上轉移真實 USDC，資金可能因合約邏輯而被支出或鎖定。未宣告身分驗證，工具清單也未公布，因此在讓助理釋出付款前應檢視合約與實際工具。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Paycrow，將其新增到工作區。

工具

10

trust_gate

Should you pay this agent? Check before sending money. Returns a go/no-go decision with recommended escrow protection parameters. Unlike other trust services, PayCrow ties trust directly to escrow protection: - High trust → shorter timelock, proceed with confidence - Low trust → longer timelock, smaller amounts recommended - Caution → don't proceed, or use maximum protection This is the tool to call BEFORE escrow_create or safe_pay.

輸入參數address必填intended_amount_usdc

trust_score_query

Full trust score breakdown for an agent address. Aggregates 4 on-chain sources: PayCrow escrow history, ERC-8004 agent identity, Moltbook social karma, and Base chain activity. Returns 0-100 score with per-source details. For a quick go/no-go decision, use trust_gate instead.

輸入參數address必填

trust_onchain_quick

Quick on-chain reputation check using only the PayCrow Reputation contract. Free, no API keys needed. Use trust_score_query for the full composite score.

輸入參數address必填

escrow_create

Create a USDC escrow with built-in dispute resolution. Funds are locked on-chain until delivery is confirmed (release) or a problem is flagged (dispute). If disputed, an arbiter reviews and rules — the only escrow service with real dispute resolution on Base.

escrow_release

Confirm delivery and release escrowed USDC to the seller. Only call this when you've verified the service/product was delivered correctly.

輸入參數escrow_id必填

escrow_dispute

Flag a problem with delivery — PayCrow's key differentiator. Locks escrowed funds and triggers arbiter review. Unlike other escrow services that say 'no disputes, no chargebacks', PayCrow has real on-chain dispute resolution. Use when service was not delivered or quality was unacceptable.

輸入參數reason必填escrow_id必填

escrow_status

Check the current state of an escrow (funded, released, disputed, expired, etc.)

輸入參數escrow_id必填

rate_service

Rate a completed escrow. After escrow_release, rate the seller's service quality (1-5 stars). This builds the reputation data that makes PayCrow's trust scores meaningful over time. Both sides can rate: buyer rates seller's service quality, seller rates buyer's conduct. Ratings are on-chain and permanent — they feed directly into trust scoring.

safe_pay

The smart way to pay an agent. Checks their trust score first, then auto-configures escrow protection based on risk. Flow: Check trust → Set protection level → Create escrow → Call API → Verify → Auto-release or auto-dispute. Protection levels (automatic): - High trust agent → 15min timelock, proceed normally - Moderate trust → 60min timelock, payment capped at $25 - Low trust → 4hr timelock, payment capped at $5 - Unknown/caution → BLOCKED — will not send funds This is the recommended tool for paying any agent. If you need manual control, use x402_protected_call instead.

x402_protected_call

Make an HTTP API call with manual escrow protection. Full control over verification and timelock parameters. For most payments, use safe_pay instead — it auto-configures protection based on seller trust. Use x402_protected_call when you need: - Custom JSON Schema verification (not just "valid JSON + 2xx") - Hash-lock verification (exact response match) - Specific timelock durations - To override safe_pay's trust-based amount limits
