Supported Assets

Every asset.
Every chain that matters.

Scrya verifies crypto held in personal wallets and on exchanges - across the networks and venues your clients actually use. No funds are ever moved or touched.

Chains we monitor.

Each network is cross-checked against several independent public data sources, so the result never relies on any single provider being available or honest.

Methods

How each asset is verified.

Different asset classes need different proofs. The certificate format is the same regardless of which path the customer takes.
01 / WALLET

Proof straight from the client’s wallet

Your client confirms ownership in a few clicks from any wallet they already use - hardware, browser or mobile. They keep full control, and Scrya can never move a thing.

Human-readable message signing · ECDSA / BIP-322 / Ed25519

02 / EXCHANGE

Exchange balances, confirmed safely

For assets on an exchange, your client grants secure, read-only access. We confirm the balance without ever being able to trade, transfer or withdraw funds.

Read-only API keys · permissions validated before any balance is read

03 / MONITORING

We keep watching, not just snapshot

Balances are cross-checked against several independent public sources and tracked over a window you choose - 48 hours by default, up to 30 days. Any change is flagged in real time.

Multiple independent blockchain data sources per network

Frequently asked questions

Which networks and coins does Scrya support?

Scrya verifies Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Tether (USDT), and USD Coin (USDC). Stablecoins are verified on the networks they are issued on (for example USDT on ERC-20, TRC-20, and SPL).

Which exchanges can clients connect?

Clients can confirm balances through secure, read-only access on major venues including Binance, Coinbase, Kraken, CoinSpot, Swyftx, BTC Markets, Independent Reserve, and CoinJar.

How is wallet ownership proven?

The client signs a human-readable message from their own wallet using ECDSA, BIP-322, or Ed25519 depending on the network. No funds move and private keys are never exposed to Scrya.

Does Scrya only take a single balance snapshot?

No. Balances are cross-checked against independent public data sources and monitored over a configurable window — 48 hours by default, up to 30 days — with material movements flagged.
