New features
|
|
|
|
- Many rust liquidator improvements.
|
|
- MangoAccount is now dynamically sized and is expandable, there is a new `AccountExpand` ix, default size of account is 8 token positions, and 2 serum3 and 2 perp positions, expanded account has 16 token positions and 8 serum3 and 8 perps for now.
|
|
- Group account - has a `creator` field which is set on creation and should never change, is used for pda derivation, has a new `fast_listing_admin` field for governance, and also has a `GroupEdit` ix to change both the admin keys.
|
|
- Group account - has a `version` field, version 0 which is used in the setup scripts for now, means serum3 and perp market registration is forbidden, and multiple banks are prevented from been added.
|
|
- Each account now has a reserved space of around 256 bytes.
|
|
- flash_loan ix 1 and 2 are removed, flash loan 3 has been renamed to just `FlashLoan`.
|
|
- `MintInfo`, `Serum3Market`, and `PerpMarket` have a field called `registration_time` which is seconds from epoch, e.g. use case how freshly has the market been added, if it was recently added then liquidity might need some time to improve
|
|
- Removed fields and commented out code for address lookup tables.
|
|
- New `TokenRegisterTrustless` ix to register tokens trustlessly.
|
|
- Insurance fund is now disabled for trustless tokens.
|
|
- `TokenRegistration` and `TokenRegisterTrustless` ixs dont take a bank_num anymore, hardcoded to 0.
|
|
- Enforced a minimum maximum rate of 50% so that rates don't fall so low that they cannot recover.

|
|
|
|
- Account data was rearranged to put fields that are often used with gPA first
|
|
- The `CreateGroup` instruction now requires an `insurance_mint` account, which is
|
|
used as the mint for the `insurance_vault` token account it creates. Pass the
|
|
USDC mint address.
|
|
- The token with `token_index` zero is now required to be the `insurance_mint`.
|
|
Trying to register a different token for index zero will now fail.
|
|
- New instruction: `LiqTokenBankruptcy` to resolve insurance fund payouts and
|
|
socialized loss for bankrupt accounts.
|
|
- The `PerpCreateMarket` instruction no longer requires a `quote_token_index`
|
|
argument. The USDC/insurance mint is always used as quote currency for perps.
|
|
- The `UpdateIndex` instruction now requires the `oracle` account to be passed
|
|
for logging purposes.
|
|
- New instructions: `AccountEdit`, `TokenEdit`, `PerpEditMarket` for reconfiguring.
|
|
- The `delegate` field on `MangoAccount` is now used and many instructions can be
|
|
called by the account delegate.
|
|
- `TokenUpdateIndexAndRate` now maintains dynamic optimal and max rates for token interest rates.
|
|
|
|
- Renamed instructions:
|
|
- create/close_group -> group_create/close
|
|
- create/edit/close_account -> account_create/edit/close
|
|
- update_index -> token_update_index
|
|
- create/set_stub_oracle -> stub_oracle_create/set
