Agentic paymentsmachine speed.
The payment session protocol for AI agents. Lock funds, stream vouchers, settle on-chain. No card required.
Built for autonomous agents

FEATURES
Everything you need to pay at scale
Primitives designed to make autonomous agent payments actually work.
Session Escrow
Every session deposits USDC on-chain. Funds are isolated, tracked, and auto-returned.
Locked Amount
Zero-Gas Vouchers
Signed off-chain at machine speed.
EIP-712 Signatures
Every voucher is cryptographically verifiable.
Aave V3 Yield
Idle funds earn yield while locked in escrow.

Three steps. One settlement.
Open a session
The agent deposits USDC into an on-chain escrow. Funds are locked, isolated per session, and immediately start earning Aave V3 yield.
Builders trust SolvoPay
From indie hackers to enterprise teams, here's what builders are saying about agent payments at machine speed.
we were literally just hardcoding api keys and hoping our agent didn't blow through our budget. solvopay was the first thing that made us feel like we had actual control over what the agent was spending.
the thing that got me was the yield. our agents hold sessions open for like 20-40 minutes at a time. that capital was just sitting there doing nothing. now it isn't.
i spent two weeks trying to figure out how to handle micropayments between my agent and the apis it was calling. solvopay solved it in an afternoon. the sdk is really clean.

the escrow model clicked for me immediately. it's basically a state channel. i didn't have to learn anything new, i just had to trust the primitive. and the primitive is solid.
our clients kept asking us how billing worked for agent actions. we had no good answer. now we do. solvopay is the answer we give them.
built a full agent payment flow in 6 hours at a hackathon. judges loved it because they could actually see the on-chain settlement happen live. that demo moment was clean.

we process thousands of agent actions per session. the idea of doing one on-chain transaction per action is insane. one settlement at the end is the only thing that makes sense at our scale.
looked at the contracts. the voucher verification logic is tight. nonce enforcement, sig recovery, liquidity index math for yield, all done right. i've seen projects cut corners here. solvopay didn't.
i don't know aave internals. i don't care about aave internals. i opened a session, deposited usdc, and my locked funds just... earned yield. that's insane for something i set up in like 30 minutes.
