Robinhood chain routes

[mpetrunic]

Goal

Enable solving USDG on Robinhood Chain from any source chain.

The core route we want to support: a user/order originating on any supported source chain settles into USDG on Robinhood Chain, with Sprinter acting as the solver. This leverages Paxos Transit as the underlying cross-chain settlement rail.

Scope

• Bridge routes (same-asset): solve USDG → USDG into Robinhood Chain from any source chain.
• Cross-chain swaps into USDG: potentially extend to solving cross-chain swaps that terminate in USDG on Robinhood Chain (e.g. USDC / USDT / PYUSD → USDG), as long as Paxos Transit supports the pair.

Economics / constraint

We only take a route when it is profitable — i.e. the fee we charge must exceed the Paxos Transit fee for that route. Routes where we cannot charge above the Paxos Transit fee are out of scope.

Notes

• Destination network: Robinhood Chain (USDG).
• Feasibility of any given swap route is gated on Paxos Transit support for that source asset → USDG pair.
