Upcoming Release - Polymer API v1.0

We're excited to announce major enhancements to Polymer's proving infrastructure that deliver sub-second proof latencies and introduce automated transaction execution capabilities.

🔧 API Method Updates & Versioning

New v1 API Endpoints

We've introduced proper API versioning with improved method naming and enhanced functionality:

Base URL: https://api.polymer.zone/v1/

Legacy (v0)	New (v1)	Purpose
polymer_requestProof	prove_request	Request proof generation
polymer_queryProof	prove_query	Query proof status
New	execute_request	Automated execution
New	execute_query	Query execution status

Enhanced Response Format

v1 responses now include the original proofRequest object for better traceability and debugging, making integration more developer-friendly.

Migration Note: Legacy v0 endpoints remain fully supported during the transition period.

⚡ Dramatic Latency Improvements

We've completely overhauled our backend infrastructure and optimized interactions with the Polymer chain:

• Enhanced API Backend: Streamlined interactions between API Backend and Polymer chain.
• Upgraded Cosmos SDK: Latest SDK version enables significantly faster block times

Performance Gains

Metric	Previous	New	Improvement
Block Time	2 seconds	100ms	20x faster
Proof Generation	4-5 seconds	< 1 second	5x faster
API Response	Variable	Consistent sub-second	Predictable performance

Result: Proof requests that previously took 4-5 seconds now complete in under 1 second.

🎯 Execute API (Beta Release)

Based on strong developer demand for simplified and automated transaction submission, we're beta-releasing our Execute API that combines proof generation with automated on-chain execution.

Key Capabilities

• Ultra-Fast Submission: Transactions land on destination chains in under 300ms
• Universal Compatibility: Any EVM chain, any contract (non-EVM support coming soon)
• Integrated Workflow: Proof generation + execution in a single API call
• End-to-End Speed: Complete cross-chain execution in 1-1.5 seconds

Workflow Comparison

// Traditional Approach: ~10+ seconds
1. Request proof (4-5s)
2. Poll for completion
3. Manual transaction submission (5-10s)

// New Execute API: ~1.5 seconds
1. execute_request (includes proof + transaction)
2. execute_query (poll until complete)

Why This Matters

This represents a massive leap forward compared to traditional cross-chain systems:

• Traditional bridges: ~2 minutes
• Existing solutions: 30+ seconds
• Polymer Execute API: 1-1.5 seconds end-to-end

🛠️ Getting Started

For Existing Users

Continue using v0 endpoints - no immediate changes required, you’ll see all the benefits of proof latency. We recommend migrating to v1 for enhanced features like execute API.

For New Integrations

Start with v1 endpoints for the best experience:

// Proof-only workflow
const response = await fetch('https://api.polymer.zone/v1/', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: "2.0",
    method: "prove_request",
    params: [{ srcChainId: 10, srcBlockNumber: 123456, globalLogIndex: 0 }]
  })
});

// Proof + Execute workflow (Beta)
const executeResponse = await fetch('https://api.polymer.zone/v1/', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    method: "execute_request",
    params: [executeEnvelope] // Proof + execution parameters
  })
});
