Chains

Kvasyr currently supports:

• Base
• Ethereum
• Polygon

Finality Mode

Kvasyr finality is tag-first by default:

• tag_finalized (default): use chain-provided finalized block tag
• tag_safe: use chain-provided safe block tag
• depth: use head - finality_depth

When a configured tag is not supported by an RPC endpoint, Kvasyr falls back to finality_depth for that chain during the current process lifetime.

Example Chain Config

{
  "8453": {
    "name": "base",
    "finality_mode": "tag_finalized",
    "finality_depth": 64
  }
}
