fn deposit(env: soroban_sdk::Env, user: soroban_sdk::Address, xlm_amount: i128)fn unpause(env: soroban_sdk::Env)Upgrade the contract WASM. Only callable by admin.

Only the configured governance contract may call this, and only these keys exist — an approved proposal naming anything else does nothing rather than silently succeeding.
fn set_param(env: soroban_sdk::Env, key: soroban_sdk::Symbol, value: i128)Lend idle XLM for the length of one transaction.
The receiver is called once and must return the amount plus the fee before this function returns. There is no credit risk: if the balance is not restored the assertion fails and the whole transaction reverts, loan included. The fee stays in the vault, so it raises the exchange rate.
Deposits, withdrawals and claims are blocked for the duration. Without that, a borrower could satisfy the balance check by depositing the borrowed XLM and mint themselves shares out of the loan.
fn flash_loan(env: soroban_sdk::Env, receiver: soroban_sdk::Address, amount: i128)fn governance(env: soroban_sdk::Env) -> soroban_sdk::AddressInitialize the staking contract.

)One-shot storage migration for a contract deployed before derived accounting.
Reconstructs PendingWithdrawals by summing unclaimed queue entries.
Required once on any contract upgraded from a build that did not record
the liability, or total_assets() counts XLM already owed to the queue.
Legacy TotalXlmStaked, TotalSxlmSupply and LiquidityBuffer entries
are left orphaned; nothing reads them.
fn migrate_v2(env: soroban_sdk::Env)Contribute realised yield to the vault.
The XLM is transferred in. There is no counter to increment: the deposit
raises the contract balance, total_assets() reads that balance, and the
exchange rate follows. The protocol fee is booked as a liability so it is
excluded from the assets backing shares until it is withdrawn.
fn add_rewards(env: soroban_sdk::Env, from: soroban_sdk::Address, amount: i128)Raw XLM held by the contract, including encumbered amounts.
fn idle_balance(env: soroban_sdk::Env) -> i128fn set_treasury(env: soroban_sdk::Env, treasury: soroban_sdk::Address)XLM backing sXLM shares.
fn total_assets(env: soroban_sdk::Env) -> i128Donate XLM to the vault with no shares minted in return.
No separate buffer counter: the donated XLM is part of the balance, so it backs shares like any other asset.
fn add_liquidity(env: soroban_sdk::Env, from: soroban_sdk::Address, amount: i128)Bump instance TTL — can be called by anyone to keep the contract alive.
fn bump_instance(env: soroban_sdk::Env)fn flash_fee_bps(env: soroban_sdk::Env) -> i128Withdraw protocol fees to the admin address. If amount > 0, withdraw that specific amount; if 0, withdraw all.
fn withdraw_fees(env: soroban_sdk::Env, amount: i128)fn get_withdrawal(env: soroban_sdk::Env, withdrawal_id: u64) -> WithdrawalRequestHand parameter control to the governance contract, once.
This is the step that makes a passed proposal actually do something. It is deliberately separate from deploying the code: handing over control of a live contract is a decision, not a side effect of an upgrade.
fn set_governance(env: soroban_sdk::Env, governance: soroban_sdk::Address)Claim a delayed withdrawal after cooldown has expired.
