THE READ LAYER FOR SOLANA
Read Solana.
Verify it.
One endpoint for every account, transaction, and token — each answer ships with a signed receipt you can check yourself. Every read proves itself, offline.
LIVE ENDPOINT
Query Solana — Get a receipt
Pick a method, run it against the live mesh, then verify the signed receipt yourself in your browser. No round-trip, no trust in us — the signature checks against Hallmark's published key.
Lamport balance of an account, stamped with the slot it resolved at.

VERIFIABLE READS FOR
WHY READ-ONLY
Built for the read path
Solana can do 65k TPS — but every read still routes through an RPC you just have to trust. No signature, no slot, no recourse.
Hallmark is the read layer that fixes that. Validators are the write layer. Hallmark is the read layer for Solana.
Reads Dominate
Over 90% of RPC traffic is reads — balances, accounts, slots. We specialize the read path so it stays fast and cheap while validators do the writing.
Built For Agents
Autonomous agents can't trust an answer they can't verify. Every response ships a signed receipt with a freshness slot they can check offline.
Geo-Latency
A mesh of staked operators across regions routes each read to the closest honest node — low latency without a single point of trust.
It's the difference between a screenshot and a signature. One you can argue with. One you can't.
WHAT YOU CAN BUILD
An explorer you can read — and verify
Slots, epochs, blocks, transactions, holders — every view backed by the same signed read path. Three widgets do the heavy lifting.
Trace funds between wallets
Every transfer drawn as a living, explorable network. Follow the money across hops without leaving the page.
Decoded, instruction by instruction
Decoded instructions, balance deltas, and logs — a transfer you can read at a glance instead of a blob of base64.
Re-check any signed response
Paste a receipt and re-verify it right in the browser. The data confirms itself — you never take our word for it.
