Built with Nirium
What's integrated with Nirium, what's built on it, and what Nirium itself depends on. Each listing goes up once its owning team approves the text.
Integrations

Pollar
Social-login wallets (email/Google), no seed phrase. nirium-pollar-adapter translates Pollar's signature into a SEP-43 auth entry to pay via x402. Example integration, merged - no evidence it runs in Pollar's own production today. A letter of intent was signed on 2026-10-08: a statement of intent, not a pilot, and no paid use.

AgentLedger
Spend governance for AI agent wallets: caps, human approvals, a decision log. Uses the policy hook in x402Fetch() to approve, hold or reject each payment before it's signed: ALLOW and WAIT-then-approval settled on testnet, and a concurrent DENY was refused. Its gate also governed 15 integration-test payments to Nirium on mainnet (Aug to Sep 2026). Its founder, Fer Mendoza, joined the Nirium team in October 2026.
Built on Nirium
Nirium uses
OpenZeppelin
x402 payment facilitator - verifies and settles on-chain, with sponsored fees. Every x402 payment route on the agent, testnet and mainnet, delegates verify/settle to their hosted facilitator. In production use, confirmed live.
DeFindex
Yield vaults on Soroban, with roles separated by contract design. The agent holds only the RebalanceManager role of a client-owned vault - that role can't withdraw funds or change roles, by contract. 4 real rebalances, all on 2026-08-06, none since - mainnet, test vault only, no clients yet.
Etherfuse
Issues tokenized CETES and runs the MXN -> CETES SPEI onramp. Test environment quotes power /ramp; the mainnet link is indirect, via DeFindex's own strategy - not a direct Nirium integration.
Trustless Work
Programmable milestone-based escrows on Soroban. 4 of our research PRs merged by their maintainer, plus a Multi-Release escrow integration for Payouts tested end to end on testnet. Deploy also tested on mainnet, but the automatic approve/release signer never ran there - full rollout on hold pending the same Art. 24 Bis 4 legal review as Treasury. A letter of intent was signed in October 2026: a statement of intent, not a paid pilot. A testnet pilot gates milestone release on anchored evidence: an agent checks the record's hash, its milestone and the service provider's signature before approving and releasing, and refused one milestone that failed. Written up as a research note, under review.
Stellar MPP SDK (@stellar/mpp)
MPP Charge on testnet: per-request USDC transfers the server verifies itself, no facilitator. Verified with settled payments on 2026-10-15; mainnet not tested.
