Overview
The Strike SDK is a Rust crate for programmatic trading on Strike prediction markets. It wraps all on-chain interactions — order placement, collateral management, event streaming, and market reads — into a typed, async API.
Design Philosophy
The SDK is on-chain first. All trading operations go directly to BNB Chain via RPC. Live data (events, balances, market state) comes from a WSS subscription or RPC reads. The indexer is available for startup snapshots (fetching all markets, orderbook state, wallet positions, redeem backlog), but is never in the critical trading path.
Features
Order management
Place, cancel, and replace orders in batch transactions
Event streaming
Real-time WSS subscriptions with auto-reconnect
Vault & tokens
USDT approval, balance queries, outcome token / position operations
On-chain market reads
Market counts/IDs plus market_meta(factory_market_id) for factory-to-orderbook metadata
Indexer client
REST client for market snapshots, wallet positions, redeem backlog, and orderbook state
Nonce manager
Optional nonce-manager feature flag for bots sending rapid transactions
Wallet position helpers normalize known schema drift in filled-position and redeemable payloads, so integrations can use stable accessors instead of decoding multiple indexer variants themselves.
Preset Configs
Use StrikeConfig::bsc_mainnet() for BSC mainnet with default RPC, WSS, and indexer endpoints. See Client Configuration for custom setups.
Feature Flags
The nonce-manager feature enables NonceSender, a local nonce tracker for rapid transaction sending. It re-syncs and retries on simple nonce drift, and handles pending mempool conflicts conservatively without blind replacement retries. Enabled by default — disable it if you manage nonces externally.
