Indexing

Ensure submitted transactions are tracked by the Superbridge Indexer

In most cases, submitted transactions will automatically be picked up by the Superbridge Indexer. The indexer monitors supported chains and will detect and track your bridge transactions without any additional action required.

When to manually index

However, there are certain edge cases where automatic detection may not occur — for example, during periods of high network congestion, or when using less common route providers. As such, we always recommend pinging the API with the transaction hash, chain identifier, and underlying provider whenever an operation has been submitted.

This ensures your transaction is tracked reliably, regardless of network conditions.

How to index a transaction

Use the Index Transaction endpoint to notify the indexer:

curl -X POST https://api.superbridge.app/api/v1/index_transaction \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "txHash": "0x...",
    "chainId": "1",
    "provider": "across-v3"
  }'

You can identify the chain using any of the three supported formats — chainUid, chainId, or chainKey. See Chain Identifiers for details.
