SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Broadcasts pre-signed on-chain transactions across supported chains and provides gas estimation, simulation, and order tracking.

Core Features & Use Cases

  • Broadcast signed transactions on-chain across chains and track their status.
  • Estimate gas and simulate transactions to prevent failures before broadcasting.
  • Query and monitor orders for ongoing on-chain activity and supported networks.

Quick Start

Broadcast a signed transaction on a chosen chain using onchainos gateway.

Frequently Asked Questions about okx-onchain-gateway

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I broadcast a pre-signed on-chain transaction across multiple chains?▼

To broadcast a pre-signed on-chain transaction, you provide the signed raw transaction data and specify the target chain, such as Ethereum or Solana. The gateway then submits the transaction to the network and tracks its order status.

Can I estimate gas and simulate an on-chain transaction before broadcasting?▼

Yes, you can estimate gas and simulate your on-chain transaction to identify potential failures before broadcasting. This prevents failed transactions by checking execution validity and gas requirements against the target chain beforehand.

Does this onchain gateway support Solana, BSC, and Base networks?▼

The onchain gateway supports Ethereum, Solana, BSC, Base, X Layer, and other networks. It enables raw transaction broadcast, gas checks, and status queries across these multiple supported chains within a single interface.

Why does the gateway require a pre-signed transaction instead of signing it itself?▼

The gateway requires a pre-signed transaction because it does not sign transactions itself, enforcing strict safety checks by keeping private key management separate from the broadcasting process. You must provide the signed transaction and sender address.

What is the best way to track the status of a broadcasted on-chain transaction?▼

The best way to track the status of a broadcasted on-chain transaction is using the gateway's order tracking feature. It monitors ongoing on-chain activity and queries transaction status across supported networks after broadcasting.
