content: # NEAR OpenClaw Skills

Specialized agentic skills for NEAR Protocol, designed for OpenClaw.

## Gas Optimizer Skill

Optimizes gas usage and provides cost comparisons.

- `near_gas_estimate`: Estimate TGas for a transaction.
- `near_gas_optimize`: Get specific optimization tips for a contract.
- `near_gas_history`: View historical gas trends for an account.
- `near_gas_compare`: Compare NEAR costs to Ethereum (L1).

## On-Chain Analytics Skill

Direct insights from the NEAR blockchain.

- `near_analytics_network`: Real-time network health and throughput.
- `near_analytics_whales`: Detection of high-value transactions.
- `near_analytics_trending`: Identification of most used contracts.
- `near_analytics_defi`: TVL and volume stats for NEAR DeFi.

## Integration

These skills are compatible with the OpenClaw skill runner and can be published directly to MoltHub.
