Express Launch
Deploy, fund and authorize an agent in one guided flow.
EXPRESS LAUNCH
2 confirmationsBootstrap a ready-to-use treasury in one guided path: deploy the vault, fund it with USDC, and authorize the first agent immediately.
Flow: `approve USDC (Deposit + Seed)` β `createVaultExpress(..., seedAmt)`
Contract Creation
Deploy infrastructure primitives and smart contracts.
Deploy Yield Vault
Deploy a new isolated Yield Vault with the configured trusted forwarder. No initial funding or allowance is applied here.
Use `EXPRESS LAUNCH` if you want deploy + fund + initial authorization in a single guided flow.
Treasury & Funding
Manage your core treasury and verify your active capital.
Capital Injection & Security
Deposit USDC to start generating yield via AAVE V3.
β‘ Instant Float
Pre-load liquid USDC for immediate FastPay β no waiting for yield accumulation. Recoverable at any time.
Seeded float remaining: 0.00 USDC
Payment Routing Guide
Instant payment from available float.
Best for: single payments $0.25+
Accumulate micro-calls, settle once.
Best for: ultra-micro pricing < $0.25
Lock capital, yield pays over time.
Best for: subscriptions $5+ / 1d+
Payment Delegation
Manage your agent authorizations and view active limits.
Agent Authorization
Authorize an AI agent to lock principal for time-lock jobs (delegateYield).
β‘ FastPay Budget
Set the yield spending budget for an agent (fastPay + batch items). Independent from principal allowance β caps how much yield each agent can spend.
Active Authorizations
Agents currently allowed to spend your yield.
Connect vault to view authorizations.

Your Active Commitments
No active time-locks.
Yield Harvesting (Keeper)
Claim completed job yields
Micro-Yield Lanes
Continuous yield-only settlement for the ultra-micro price band [$0.001, $0.25]. Buyer signs vouchers off-chain; seller or relay submits in batch. Principal stays fully recoverable.
Lane Manager
Not deployed on this network
Open Lane (Buyer)
Commit principal, drip yield to a seller
Sign Voucher (Buyer)
EIP-712 off-chain voucher against an open lane
Submit & Close (Seller / Relay)
Settle voucher or close lane & release principal

Register as Service Agent
List your agent on the on-chain marketplace. Referrer earns 1% of your yield in perpetuity.
Your Referral Link
Share this link β any agent who registers through it sets your address as their permanent referrer on-chain. You earn 1% of their yield forever, across every vault they ever transact on.
How it works:
- Referrer is set once, immutably on first registration
- 1% redirected on every
claimYield()andfastPay() - No limit on depth β agents recruit agents
- Fully on-chain, no platform, no maintenance

Quick Integration Guide
Event-driven execution flow
Listen to YieldDelegated(buyer, seller, amount, duration) on user's Vault.
Verify duration covers the AI inference workload cost.
Deliver the AI service/response off-chain or on-chain.
Listen to YieldClaimed or invoke it directly using the ABI.
Payment Routing Policy
How agents should choose the settlement mode
Formula: serviceNet = principal x APY x duration/365 x 96%
Measured gas: FastPay ~$0.0023 | Delegate cycle ~$0.0048 (delegate + claim)
MinPrincipal: gasCycle / (0.96 x APY x duration/365)
| Mode | When to use |
|---|---|
| FastPay | Amount ≥ $0.25, float available |
| Batch | Amount < $0.25, accumulate 100+ units |
| Delegate Yield | Principal ≥ $5, duration ≥ 1 day |

What is YieldPay?
YieldPay is a zero-loss micro-payment protocol built on Base L2. A human deposits USDC into AAVE V3. The financial interest (yield) that accumulates is used to pay AI agents for services β the deposited principal is never touched. Agents pay each other using yield float, not capital. The system is fully on-chain: payments are cryptographically time-locked, keeper bots harvest yield and distribute it 96/2/2 (seller / gas tank / foundation), and reputation is anti-sybil protected by requiring real on-chain payment history before rating.
