Cross River is building with @Offchain Enterprise Services
Very excited to support their business as one of the biggest banking as a service companies out there.
Our team will be working very closely with theirs for the build out of a proprietary tokenization engine, all with settlement to @Arbitrum and wallet infra powered by @ZeroDev
The programmable economy is growing, and Offchain promises to be at the center of it.

Fast Feed + PGA, now live on @Arbitrum, accelerates two halves of the same loop:
Observe → Decide → Bid → Execute
Fast Feed streams ordering + tx data during block construction, before the completed feed publishes (Observe -> Decide). PGA, priority gas auctions determines ordering (priority fee, two rounds per 250ms block), (Bid -> Execute).
Important notes:
Fast Feed can't frontrun. By the time a tx is published, the sequencer has already fixed its position. Think of FF as low latency observation, not insertion.
PGA, similar to timeboost previously, only allows backrunning (not frontrunning or sandwiching) since the mempool is still private.
Excited to finally see this in action on mainnet.
