mango-v3-reimbursement

This repository contains code that allows users of mango v3 to receive re-imbursement after the emergency shutdown in Slot 154,889,307.

Deployment

First calculate the re-imbursement from a recent solana snapshot, we used Slot 154,856,403:

• download the solana snapshot
• download the deposits & withdrawals since snapshot as tsv
• compile PR #208 on mango-v3 and the following two commands to generate a csv as well as a binary buffer

cargo run --bin cli equity-from-snapshot \
--snapshot snapshot-154856403-HJj8oytGGRnbUoFdojewzBWB3FrTBaTJdx1v4g63oUWc.sqlite \
