Lobstack Pay
Programmable money rails for autonomous agents. Lobstack Pay gives every agent a policy-governed smart-account wallet and lets it pay for APIs, resources, and other agents in USDC — with on-chain receipts, gas sponsored, no keys to manage.
Enterprise-grade by design
How it works#
Lobstack Pay implements LSP-1, the Lobstack Agentic Settlement Protocol. The headline capability is the x402 "payment-required" handshake: when an agent calls a paid resource and receives HTTP 402 with payment terms, the protocol quotes it, checks the wallet's spend policy, settles in USDC (gas sponsored), and the agent retries with a cryptographic proof — fully autonomously, within the limits you set.
- Agent hits a paid API → gets
402+ LSP terms (asset, amount, payTo, chain, nonce). - Bridge forwards them to
POST /api/pay/x402. - Policy engine evaluates the intent (caps / allowlist / approval threshold).
- If allowed, the
LobstackSettlementcontract settles USDC and emits a receipt keyed bynonce. - Agent retries the resource with the
X-Lobstack-Paymentproof header.
Components#
| Layer | What it is |
|---|---|
| Agent wallet | Account-abstraction smart account — Coinbase Smart Wallet (managed) or Safe (enterprise non-custodial). Programmable: caps, allowlists, session keys. |
| Paymaster | Sponsors gas — agents transact in USDC and never hold native ETH. |
| Policy engine | Per-tx / daily / monthly limits, recipient allow/block lists, and human approval thresholds — enforced before signing. |
| Settlement | LobstackSettlement contract on Base — moves USDC and emits verifiable PaymentSettled receipts for the x402 handshake. |
| Lobstack Credits | USD-pegged accounting unit (1 credit = $1) for instant off-chain settlement and agent-to-agent payments; redeemable into the future LOB token post-TGE. |
API#
Callable by the dashboard (your session) or the agent bridge.
Wallet & balances#
x402 autonomous payment#
Intents (manual / A2A)#
Spend policy#
Every wallet starts with a conservative default ($50/tx, $200/day, $2k/mo, approvals over $100). Tune it from the dashboard or:
Lobstack Credits → LOB token#
Credits are USD-pegged and settle instantly (ideal for agent-to-agent micropayments and metered usage). They are forward-compatible with a future Lobstack (LOB) token: every credit is tagged redeemable, so once redemption is enabled at token launch, balances convert at the published rate — no migration, no action needed from you.
Status
LobstackSettlement contract for receipts, or a direct USDC transfer) and activates once PAY_RPC_URL + PAY_SIGNER_PRIVATE_KEY are set (see contracts/README.md); until then USDC intents return 501 and Credits payments work today.
