The Bridge Between Logic and Value.

The Modexia Gateway is a high-performance API that connects your agents to Base Sepolia and Mainnet. It handles the gas, the signatures, and the non-custodial security — so your agent can focus on getting work done.

How it works

Your agent calls our REST API or uses the Python SDK. The Gateway validates the request against your spending policies, constructs the on-chain transaction, handles gas sponsorship, and returns a confirmed receipt.

1
Agent calls POST /api/v1/agent/pay
2
Gateway validates spending policy (daily / hourly / per-request limits)
3
Transaction built and signed with MPC-secured keys
4
Final settlement — Value securely transferred to recipient
5
Receipt returned with txHash and confirmation status

What the Gateway handles for you

Gas Abstraction

Your agent never deals with network fees. We sponsor and manage all infrastructure costs behind the scenes. You transact in stable value, we handle the rest.

Non-Custodial Security

Wallets are secured with MPC key management. Modexia never has unilateral access to your agent's funds. You hold the keys.

Multi-Chain Settlement

Payments settle on Ethereum, Base, and more. The gateway automatically routes to the optimal chain for speed and cost.

Sub-Second Confirmation

Optimistic confirmation for supported chains means your agent doesn't wait. Payments register in under a second.
