What WBTC represents
WBTC is a tokenized Bitcoin representation rather than native BTC. WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs.
WBTC wrapper and underlying-asset boundary
WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. Contract transfers, approvals, and unwrap activity remain visible and require native network gas.
WBTC contract networks
Ethereum, Base, Osmosis, Sonic, Berachain Bepolia, Telos, Unichain, Swellchain, Monad, Soneium, BNB Chain, Sui, Solana, Optimism, Aptos, Avalanche, BOB, Arbitrum, Polygon, Linea, Scroll, zkSync Era, Hyperliquid (HyperEVM), Tron contain recorded contract representations. Never send the wrapper to an underlying-asset address unless an explicit unwrap route provides that destination.

WBTC recorded token precision
The contract representations currently share one recorded decimal format, but contract identity and network still require independent verification.
Receiving WBTC without a network mismatch
A WBTC destination requires the exact contract on the selected smart-contract network. Do not send WBTC to a native Bitcoin address. WBTC can use different contracts on different networks.

WBTC privacy and wallet linking
Approvals, token transfers, wallet reuse, amounts, timing, and later consolidation can remain visible. Private Route availability and identity requirements must be checked separately.
