REPLACED BY #254

Overview

Whenever you will submit a trade on Sushi.com if your trade is eligible for getting its transaction cost refunded you will get a notification saying so. If your trade is not eligible it will be immediately submitted through a private RPC layer: you still get the benefit of a protected trade submission you just won’t get a transaction rebate. If your trade is eligible for transaction cost rebate, you will receive your rebate within 35 blocks.

Version 2 will have a reputation system in which transaction cost is paid upfront for accounts with good account standing, otherwise the rebate system will apply.

RPC analytics/KPI's will be provided, if you have any certain requirements let us know.

parameters of endpoint:

failover: in the event of trade engine failure, transactions are sent directly to mining pools.
timeout: transaction timeout for inclusion is 60 seconds, if unable to find a solution (re: arb opportunity), it is directly sent to the mempool
payouts: for now will occur in 35 blocks

Testing and Validation

Before this is merged into the production branch, the RPC endpoint will be moved to reflect its production status, as currently the endpoint follows this naming convention:
[*.]staging.sushirelay.com.

Additionally a public dashboard for seeing current RPC traffic will be made available, here is a basic version https://manifoldx.grafana.net/dashboard/snapshot/t0YeiytXpQY92Ms0DjZx03xL4EgkCNaY

Trading markets

see our token list here: https://github.com/manifoldfinance/token-list/blob/main/manifold.tokenlist.json

Trades submitted that are not on the eligible trading markets will be directly sent to the mempool.

Timeline

We think a 2 week shakeout with this deployed under a subdomain (e.g. beta.sushi.com or something similar), to observe user errors/etc is appropriate
