Synthetic BTC rebalances – cbBTC passes 30K, wBTC declines

cbBTC circulation surpassed 30,000 tokens in recent weeks through large on-chain transfers and new issuances. The synthetic Bitcoin token is backed and issued through Coinbase's token program.

wBTC's share of tokenized Bitcoin has fallen from recent highs as holders and institutions diversify their synthetic BTC holdings. Market-wide figures show reallocation of tokenized BTC across different wrapper tokens.

Several large corporate treasury purchases and exchange custody programs directed fresh demand to cbBTC issuance channels. Some long-time wBTC holders partially rebalanced into alternative wrapped tokens or on-exchange custody products.

The supply increase coincided with continued activity in spot and derivative Bitcoin markets. Multiple firms announced or expanded tokenized asset treasury strategies during the same period.

cbBTC offers different custody arrangements and on-chain transparency compared to wBTC. These features have influenced where large buyers choose to hold tokenized Bitcoin positions.

Blockchain analytics show cbBTC issuance accelerated in July and August 2025. Daily issuance volumes for cbBTC reached peaks of over 1,000 tokens on several trading days.

The wBTC supply remained relatively stable around 155,000 tokens, while cbBTC grew from approximately 15,000 tokens in June to over 30,000 currently. The shift represents changing institutional preferences for tokenized Bitcoin custody.

Exchange custody programs and institutional treasury managers cite counterparty risk considerations when selecting between different wrapped Bitcoin products. Some prefer exchange-backed tokens while others favor decentralized alternatives.

The overall supply of tokenized Bitcoin across all wrapper types continues growing as institutions add digital assets to their treasuries. Total wrapped Bitcoin supply exceeds 200,000 tokens across all products.

Other synthetic Bitcoin tokens, including tBTC and sBTC, maintain smaller market shares. cbBTC and wBTC account for the majority of tokenized Bitcoin volume.

Market participants monitor custody arrangements and reserve transparency when choosing between different wrapped Bitcoin options. Each product offers different smart contract integrations and institutional features.

Tokenized Bitcoin enables participation in decentralized finance protocols and centralized exchange trading without moving native Bitcoin across platforms.
