Question 1

What is Blockferry?

Accepted Answer

Blockferry is a developer platform that automates real-time blockchain event workflows. It normalizes transaction activity, smart contract logs, and state changes across Solana, Ethereum, Base, and other EVM networks, delivering clean event payloads directly to your backends via webhook endpoints.

Question 2

What is the failed payload retention time?

Accepted Answer

Blockferry retains failed webhook payloads for up to 14 days on our Developer tier, and 30 days on our Scale and Enterprise tiers. This gives your team sufficient time to diagnose receiver errors and manually trigger replays.

Question 3

Which blockchains does Blockferry support?

Accepted Answer

Blockferry supports Solana, Ethereum Mainnet, Base, Polygon, Arbitrum, Optimism, Tron, and BNB Chain. We are actively expanding support to other non-EVM and L2/L3 networks.

Question 4

How do I verify webhook signatures?

Accepted Answer

Every Blockferry webhook includes an `X-Blockferry-Signature` header containing a SHA-256 HMAC signature. You can verify this signature in your server code using your unique signing secret to ensure payloads are authentic.

Question 5

Can I replay historical blockchain events?

Accepted Answer

Yes. Blockferry allows you to replay historical events by specifying a starting block number or timestamp. This lets you re-populate your database or catch up on missed events safely.

Question 6

How are credits calculated?

Accepted Answer

Blockferry operates on simple, usage-based credit billing. You are billed only for events successfully dispatched to your webhook endpoints. Watchlists and rules setup are completely free.

Question 7

How does Blockferry handle reorganizations?

Accepted Answer

Blockferry monitors blockchain consensus depths. On EVM networks, we wait for a safety block depth before routing events, discarding orphan block logs automatically. On Solana, we map validator commitment logs dynamically.
