VERIFIED INTEGRATION MILESTONE

Native in the OOBE Synapse SDK.

OOBE approved and merged PR #50, adding a native UtiliaPlugin for live Solana priority fees, transaction diagnosis, unsigned simulation, and token-risk evidence.

Inspect merged PR #50 See OOBE approval

OOBE PROTOCOL × UTILIA MERGED

Four paid Solana evidence tools Available through the native Synapse plugin source.
Funded path validated A prearranged integration test completed quote, authorization, payment retry, settlement, and result delivery.
Public package release pending The merged integration is not yet included in an npm version newer than 2.0.6.

This proves external interoperability. It is not organic customer demand or recurring revenue.

ONE-COMMAND TRANSACTION SUPPORT

Signature in.
Evidence out.

The wallet-funded client verifies the official receiver and spend ceiling before it pays. The response separates what happened on-chain from what the agent should safely try next.

AGENT-NATIVE

One endpoint. Six paid tools.

Run the local npm bridge in any stdio MCP client. It discovers pricing, verifies the receiver and spend ceiling, signs USDC locally, and returns structured document or Solana data.
