FAQPage Schema

How do I estimate gas prices for blockchain transactions across multiple networks?▼

To estimate gas prices for blockchain transactions, this Skill retrieves current gas prices and calculates gas limits for specific transactions across multiple EVM and Solana networks using OKX OnchainOS integration.

Can I simulate blockchain transactions before broadcasting them to the network?▼

Yes, you can simulate blockchain transactions by performing dry-runs to predict execution outcomes and identify potential issues before broadcasting signed transactions to EVM or Solana chains.

What blockchains are supported for broadcasting and tracking transactions?▼

Supported blockchains for broadcasting and tracking transactions include XLayer, Solana, Ethereum, Base, BSC, Arbitrum, and Polygon, handling both EVM and Solana network architectures.

Does this approach support both legacy and EIP-1559 gas models?▼

Yes, blockchain transaction broadcasting supports both legacy and EIP-1559 gas models, ensuring accurate gas estimation and execution compatibility across various supported EVM chains.

How do I track the status of a broadcasted blockchain transaction?▼

You track the status of broadcasted blockchain transactions by monitoring their lifecycle using a specific order ID, which provides reliable on-chain execution updates across supported networks.

Why use a transaction simulation gateway instead of direct blockchain interaction?▼

Using a transaction simulation gateway removes the complexity of direct blockchain interaction by providing a unified interface for gas estimation, execution dry-runs, broadcasting, and status tracking across numerous networks.
