Treasury & payments for Stellar agents
Nirium plans the transactions; you sign with your own wallet.
Nirium is a non-custodial treasury and payments layer for Stellar. It plans and assembles transactions — returning unsigned XDR — while signing stays entirely with the connected wallet. Nirium thinks; you sign.
It ships as an npm package (npm i nirium) that exposes an Agent you can drive from the browser. The first integration is x402 (programmatic payments), followed by an audit trail, with treasury/CETES (yield via Etherfuse) as the flagship once it reaches mainnet.
In this demo, Nirium plugs into Pollar exactly like the DeFindex or Blend adapters: the adapter runs client-side with public information only, calls Nirium for the unsigned XDR, and the Pollar SDK signs and submits it with your connected wallet. No secret key ever touches the frontend — your signature is the authorization.
