Wallet flow graphs are live in the explorer.

See where the funds actually go. Every transfer drawn as a network you can read, and the answer still ships with a signed receipt.

Free test queries are open. No login.

Hit the live endpoint, check latency against a real node, and verify the receipt in your own browser before you commit to anything.

API keys are live in the dashboard.

Sign in, generate a key, and your reads get higher limits with per-key usage you can watch. The free tier still works with no key at all.

The SDK is live on @npmjs

npm i hallmark-sdk

One call reads, one call verifies:
const { result, receipt } = await hallmark.getBalance(addr)
await hallmark.verify(receipt)

$HALLMARK is the access layer, not a sticker on the side.

Free: no token.
Holder: hold to lift your limits.
Pro and Enterprise: higher tiers still.

Higher tier, higher limits. Full details at launch.

Launching soon on @solana

Solana can do 65k TPS. Reading it still means trusting whatever RPC answers you.

Hallmark is the read layer that fixes that. Query any account, transaction, or slot and get back a cryptographically signed receipt that proves the data is real.
