-## Liquidator Bot - -Monitors Templar lending markets and performs liquidations when borrowers fall below their collateralization ratio. - -### Key Features - -- **Strategy Pattern**: Pluggable liquidation strategies (Partial/Full) -- **Multiple Swap Providers**: RheaSwap and NEAR Intents integration -- **Production-Ready**: Comprehensive error handling, logging, and profitability analysis -- **Gas Optimization**: Smart profitability checks prevent unprofitable liquidations -- **Concurrent Processing**: Configurable concurrency for high throughput -

Swap provider implementations - - `mod.rs` - SwapProvider trait and wrapper - - `rhea.rs` - Rhea Finance DEX integration - - `intents.rs` - NEAR Intents cross-chain swap integration -- `common/src/lib.rs` -

-### Running the Bot - -```bash -liquidator \ - --registries registry1.testnet registry2.testnet \ - --signer-key ed25519: \ - --signer-account liquidator.testnet \ - --asset nep141:usdc.testnet \ - --swap near-intents \ -

-#### Required Arguments - -- `--registries` - List of registry contracts to query for markets (e.g., `templar-registry1.testnet`) -- `--signer-key` - Private key of the signer account (format: `ed25519:...`) -- `--signer-account` - NEAR account that will perform liquidations (e.g., `liquidator.testnet`) -- `--asset` - Asset specification for liquidations, format: `nep141:` or `nep245:/` -- `--swap` - Swap provider to use: `rhea-swap` or `near-intents` - -#### Optional Arguments - -- `--network` - NEAR network to connect to: `testnet` or `mainnet` (default: `testnet`) -- `--timeout` - Timeout for RPC calls in seconds (default: `60`) -- `--interval` - Interval between liquidation runs in seconds (default: `600`) -- `--registry-refresh-interval` - Interval to refresh market list in seconds (default: `3600`) -- `--concurrency` - Number of concurrent liquidation attempts (default: `10`) -- `--partial-percentage` - Percentage of position to liquidate (1-100, default: `50`) -- `--min-profit-bps` - Minimum profit margin in basis points (default: `50` = 0.5%) -- `--max-gas-percentage` - Maximum gas cost as percentage of liquidation amount (default: `10`) - -### How It Works - -1. **Market Discovery**: Fetches all deployed markets from specified registries -2. **Position Monitoring**: Continuously checks borrower positions in each market -3. **Oracle Prices**: Fetches current prices from oracle contract -4. **Liquidation Decision**: - - Checks if borrower is below required collateralization ratio - - Calculates liquidation amount using configured strategy - - Validates profitability (considering gas costs and profit margin) -5. **Swap Execution**: If needed, swaps assets to obtain borrow asset -6. **Liquidation**: Sends `ft_transfer_call` to trigger liquidation -7. **Logging**: Records all attempts with success/failure details - -### Liquidation Strategies - -#### Partial Liquidation (Default) - -Liquidates a percentage of the position (default: 50%): -- Reduces market impact -- Lower gas costs (~40-60% savings) -- Allows multiple liquidators to participate -- More gradual approach to underwater positions - -#### Full Liquidation - -Liquidates the entire position: -- Maximizes immediate profit -- Clears position completely -- Higher gas costs -- More aggressive approach - -### Swap Providers - -#### Rhea Finance - -Production-ready DEX integration: -- Concentrated liquidity pools (DCL) -- Configurable fee tiers (default: 0.2%) -- NEP-141 token support -- Contract: `dclv2.ref-finance.near` (mainnet), `dclv2.ref-dev.testnet` (testnet) - -#### NEAR Intents - -Cross-chain swap integration: -- Solver network for best execution -- 120+ assets across 20+ chains -- NEP-141 and NEP-245 support -- HTTP JSON-RPC to Defuse Protocol solver relay -- Contract: `intents.near` (mainnet), `intents.testnet` (testnet) - -### Code Examples - -#### Fetching Market Configuration - -```rust -async fn get_configuration(&self) -> LiquidatorResult { - view( - &self.client, - self.market.clone(), - "get_configuration", - json!({}), -

-#### Calculating Liquidation Amount - -The strategy determines how much to liquidate based on: -1. Market's maximum liquidatable amount -2. Strategy percentage (for partial liquidations) -3. Available balance in bot's wallet -4. Economic viability (minimum 10% of full amount) -5.
