Kujira.Ghost (kujira v0.1.80)

Kujira's lending platform.

It has a vault-market architecture, where multiple Market can draw down from a single Vault. A Market must be whitelisted, as the repayment is guaranteed by its own execution logic, e.g. being over-collateralised and having a connection to Orca to liquidate collateral when needed

Summary

get_deposit(channel, borrower)

Gets the total deposit value of an address in a Vault. Under the hood, this queries the addresses balance of the receipt token, and adjusts it by the deposit_ratio

get_deposit(channel, vault, borrower)

get_market(channel, address)

Fetches the Market contract and its current config from the chain.

get_vault(channel, address)

Fetches the Vault contract and its current config from the chain

list_markets(channel, code_ids \\ [291])

Fetches all Markets

list_positions(channel, market, vault)

Loads all positions via query_state_all, inheriting the same memoization

list_vaults(channel, code_ids \\ [316])

Fetches all Vaults

load_market(channel, market)

Loads the current Status into the Market

load_orca_market(channel, market, precision \\ 3)

Loads the Market into a format that Orca can consume for health reporting

load_position(channel, market, borrower)

Loads a Position by borrower address

load_vault(channel, vault)

Loads the current Status into the Vault

load_vault_oracle_price(channel, vault)

stream_positions(channel, market, vault)

Creates a lazy stream for fetching all positions for a Market

token_meta(t1, t2)
