Spark Protocol is a widely used Lending service on Ethereum, which makes it a favorite target for phishing. This post breaks down exactly how Spark Protocol scams work so you can recognize them instantly.
Step 1: the bait
It starts with a link — an ad at the top of search results, a reply from a fake support account, or a message in a group chat. The link points to a domain that looks like spark.fi but is not it: extra words, swapped letters, or an unusual ending.
Step 2: the perfect copy
The fake Spark Protocol page is a pixel-perfect clone. Everything looks right, so you connect your wallet without a second thought. This is where the trap closes.
Step 3: the malicious signature
Instead of a normal connection, the site asks you to sign a transaction or approval. On a real Spark Protocol this might be routine — on the clone it is a drainer that grants the attacker permission to move your tokens or NFTs. Once you approve, your assets are gone.
The Spark Protocol phishing checklist
- Confirm the domain is exactly spark.fi — nothing more, nothing less.
- Never reach Spark Protocol through an ad or a link someone sent you.
- Read every signature request. Reject anything granting broad or unlimited access.
- Never enter your seed phrase — Spark Protocol will never ask for it.
- If connecting via WalletConnect, verify the request matches the real site.
