Pause the contract (emergency stop)
When paused, all user-facing functions are disabled except admin functions. This is an emergency mechanism to protect user funds in case of discovered vulnerabilities.
NotAdmin - If caller is not the adminfn pause(env: soroban_sdk::Env) -> Result<(), soroban_sdk::Error>
Check if a contract is an approved game
fn is_game(env: soroban_sdk::Env, id: soroban_sdk::Address) -> bool
Unpause the contract
Restores normal contract functionality after emergency pause.
NotAdmin - If caller is not the adminfn unpause(env: soroban_sdk::Env) -> Result<(), soroban_sdk::Error>
Update the contract WASM hash (upgrade contract)
NotAdmin - If caller is not the adminfn upgrade(
env: soroban_sdk::Env,
new_wasm_hash: soroban_sdk::BytesN<32>,
) -> Result<(), soroban_sdk::Error>
Add a game contract to the approved list
NotAdmin - If caller is not the adminfn add_game(
env: soroban_sdk::Env,
id: soroban_sdk::Address,
) -> Result<(), soroban_sdk::Error>
End a game session with outcome verification
Requires game contract authorization. Both players' FP wagers are spent/burned. Only the winner's wager contributes to their faction standings. ZK proof verification handled client-side for MVP.
SessionNotFound - If session doesn't existInvalidSessionState - If session is not PendingInvalidGameOutcome - If outcome data doesn't match sessionProofVerificationFailed - If ZK proof is invalidfn end_game(

Get the admin address
fn get_admin(env: soroban_sdk::Env) -> soroban_sdk::Address
Get epoch information
Returns current epoch if no number specified, otherwise the specified epoch.
EpochNotFinalized - If requested epoch doesn't existfn get_epoch(
env: soroban_sdk::Env,
epoch: Option,
) -> Result
Check if contract is paused
fn is_paused(env: soroban_sdk::Env) -> bool
Update the admin address
NotAdmin - If caller is not the current adminfn set_admin(
env: soroban_sdk::Env,
new_admin: soroban_sdk::Address,
) -> Result<(), soroban_sdk::Error>
Get the current configuration
fn get_config(env: soroban_sdk::Env) -> Config
Get player information
Returns complete persistent player data including selected faction, total deposited, and deposit timestamp.
UserNotFound - If user has never interacted with the contractfn get_player(
env: soroban_sdk::Env,
user: soroban_sdk::Address,
) -> Result
Start a new game session
Locks factions and fp for both players. If this is a player's first game in the epoch, initializes their fp and locks their faction.

Cycle to the next epoch
Finalizes current epoch (determines winner, withdraws BLND, swaps to USDC, sets reward pool) and opens next epoch.

Remove a game contract from the approved list
NotAdmin - If caller is not the adminfn remove_game(

Initialize the contract
Sets up the admin, external contract addresses, and creates the first epoch.
admin - Admin address (can modify config and upgrade contract)fee_vault - fee-vault-v2 contract addresssoroswap_router - Soroswap router contract addressblnd_token - BLND token addressusdc_token - USDC token addressepoch_duration - Duration of each epoch in seconds (default: 345,600 = 4 days)reserve_token_ids - Reserve token IDs for claiming BLND emissions (e.g., vec![&env, 1] for reserve 0 b-tokens)AlreadyInitialized - If contract has already been initializedfn __constructor(

Update global configuration
Allows admin to update specific configuration parameters. Only updates parameters that are provided (non-None).

Select a faction for the user
Sets the user's persistent faction preference. Can be changed at ANY time. If you haven't played a game this epoch, the new faction applies immediately. If you've already played this epoch, the current epoch stays locked to your old faction, and the new selection applies starting next epoch.
faction - Faction ID (0=WholeNoodle, 1=PointyStick, 2=SpecialRock)InvalidFaction - If faction ID is not 0, 1, or 2fn select_faction(
env: soroban_sdk::Env,
user: soroban_sdk::Address,
faction: u32,
) -> Result<(), soroban_sdk::Error>
Get player's epoch-specific information for the current epoch
Returns complete epoch-specific data including locked faction, available/locked FP, total FP contributed, and balance snapshot.
NEW BEHAVIOR: If user hasn't played any games this epoch yet, calculates what their FP WOULD be based on current vault balance without writing to storage. This allows UIs to display FP before the user's first game.
FactionNotSelected - If user hasn't selected a faction yetfn get_epoch_player(
env: soroban_sdk::Env,
user: soroban_sdk::Address,
) -> Result
Claim epoch reward for a user for a specific epoch
Users who contributed FP to the winning faction can claim their share of the epoch's reward pool (USDC converted from BLND yield).
Note: To check claimable amounts or claim status before calling, use transaction simulation. This is the idiomatic Soroban pattern.
Amount of USDC claimed
