PropAMM Bundle Submission

Proprietary AMMs (PropAMMs) let market makers stream live, signed price quotes directly to block builders, keeping on-chain pricing in step with real-time market conditions rather than relying on a passive bonding curve. This means tighter spreads and better execution for trades routed through PropAMM liquidity, compared to trading against a stale pool price.

pamm_submit_bundle is a dedicated endpoint for submitting bundles that route through PropAMM liquidity on BSC. It gives traders and searchers a direct path to this liquidity through bloXroute's Cloud API, with the same fast, reliable bundle delivery you get from blxr_submit_bundle today.

This service is available via Cloud API only.
