Networks

GreyWallet covers Bitcoin, Litecoin, Dogecoin, Solana, Ethereum, Optimism, BNB Smart Chain, Polygon, zkSync Era, Base, Arbitrum, Avalanche, Linea, Blast, Scroll, Cronos, XRP Ledger, Tron, Aptos, Movement, Sui. Do not assume a chain that is not on that list.

Seven key spaces

• Bitcoin — UTXO. Bitcoin, Litecoin, and Dogecoin. Isolated from EVM account models. Restore against this family’s path.
• EVM — Ethereum, supported L2s, and Cronos. One signing model across the set. Each network is still a separate chain: the same ticker on another L2 is a different asset.
• Solana — Independent key space from Bitcoin and EVM.
• Aptos — Move. First-class, own derivation family. Movement sits with Aptos.
• Sui — Move. First-class, own derivation family.
• XRP — XRP Ledger. Own key space — not EVM and not Bitcoin.
• Tron — Own key space. Restore against the Tron family.

A phrase can back accounts across families. Each family has its own default path. Restoring Bitcoin with an EVM path will not find the Bitcoin account.

All networks, or one

Assets and activity can span the supported set. GreyWallet is one interface over those networks — not a separate app per chain. A send, receive, or contract call still happens on one network. Select that network before you transact.

USDT on Ethereum is not USDT on BNB Smart Chain. ETH on Ethereum is not ETH on Base as a deposit target — the address and the chain must both match what the sender uses.

DeFi and NFTs

Positions and collections surface on Ethereum, Optimism, BNB Smart Chain, Polygon, Base, Arbitrum, Avalanche, Linea, and Solana. Other supported networks keep balances and transfers on those surfaces. This documentation does not name protocols. If a protocol is not in the app, it is not documented as integrated.
