Circle revealed cirBTC in May 2026 as its institutional wrapped Bitcoin product, with a public waitlist at circle.com/cirbtc. As of this writing, cirBTC is not live. Circle has stated cirBTC will launch on Ethereum and Arc first, with multichain expansion to follow, and that the rollout is "subject to applicable regulatory approvals." This article tracks exactly what Circle has said publicly, what remains unconfirmed, and how cirBTC's announcement-to-mainnet arc compares with wBTC (2019) and cbBTC (2024).
​

Circle confirmed cirBTC in May 2026 via circle.com/cirbtc and an accompanying press release. The product is institutional wrapped BTC, 1:1 reserve-backed, launching on Ethereum and Arc, with a waitlist now open. No firm mainnet date has been published.
​

The circle.com/cirbtc page positions cirBTC as Circle's third reserve-backed asset alongside USDC and EURC, built on the same compliance and transparency model. Circle named Ethereum and Arc (its own L1) as the first two networks. The page explicitly uses "coming soon" language and gates access via waitlist signup, which Circle states is open to OTC desks, market makers, lending protocols, and corporate treasuries first. No public testnet contract address, audit report, or specific calendar date has been shared as of May 2026.
​

Circle has not committed to a public launch date. The official framing is "coming soon, subject to applicable regulatory approvals." Speculating beyond that would be fabrication. What we can track are the visible milestones Circle has put on record.
​

The publicly stated milestone sequence, in order, is: announcement and waitlist (May 2026, complete), institutional onboarding, testnet deployment on Ethereum and Arc, mainnet launch on Ethereum and Arc, then multichain expansion. Circle has not given a date or even a quarter for any post-announcement milestone. Anyone publishing a specific launch month is either citing a non-public source or guessing. Treat unsourced calendar claims with skepticism.
​

Circle has not enumerated the specific approvals. Based on Circle's existing regulatory perimeter for USDC and EURC, the most likely scope includes New York Department of Financial Services (NYDFS) review and state money transmitter license updates across the US footprint Circle already operates in.
​

Circle holds a NYDFS BitLicense and is supervised across multiple US state money transmitter regimes. USDC is issued under that perimeter. cirBTC is a different asset class (wrapped BTC rather than a stablecoin), so NYDFS and state regulators will likely review reserve structure, custody arrangements, and redemption mechanics before sign-off. Circle has not confirmed whether cirBTC will be issued by the same Circle entity as USDC or a new vehicle. Until that's disclosed, the exact regulatory path remains an open question. The "subject to applicable regulatory approvals" phrasing on circle.com/cirbtc is the only official statement.
​

Wrapped BTC products have followed different announcement-to-mainnet arcs. wBTC moved from concept to mainnet in roughly nine months in 2018-2019. cbBTC moved faster, with Coinbase compressing the public arc to a few months in 2024. cirBTC's pace is still unknown.

The wBTC and cbBTC arcs are useful reference points, not predictions. Coinbase moved fastest because cbBTC piggybacked on Coinbase's existing custody, exchange, and compliance stack. Circle has a comparable institutional footprint (USDC reserves, Circle Mint, BitLicense), which is one reason some observers expect a relatively short arc. But Circle has not endorsed any such estimate, and the wrapped-BTC reserve and custody arrangements may require additional review beyond what USDC needed.
​

Circle has said cirBTC will expand multichain after the Ethereum and Arc launches, without naming the next networks. Likely candidates based on USDC's footprint include Base, Solana, Avalanche, and other chains where Circle already runs native USDC, but Circle has not confirmed.
​

Two things make multichain expansion easier for Circle than for prior wrapped-BTC issuers. First, USDC is already deployed natively on 20+ chains, so Circle's deployment playbook is mature. Second, Circle's Cross-Chain Transfer Protocol (CCTP) provides a burn-and-mint primitive that cirBTC could plausibly inherit, though Circle has not confirmed a CCTP-equivalent for cirBTC. Until Circle publishes the post-mainnet roadmap, multichain timing remains unstated.
​

The cirBTC waitlist prioritizes institutional users: OTC desks, market makers, lending protocols, and corporate treasuries. Retail self-mint is not part of the announced product. Access on day one will likely route through Circle Mint accounts.
​

This mirrors the USDC and EURC distribution model, where authorized participants mint and redeem at par via Circle Mint, and retail accesses the asset on secondary venues. For cirBTC, that means OTC desks and market makers will be the first liquidity providers, lending protocols (Aave, Morpho, Sky) will likely list cirBTC as collateral once supply ramps, and corporate treasuries will use it for onchain BTC exposure. Circle has not published listing partners or initial mint allocations.
​

Sign up for the waitlist at circle.com/cirbtc, scope integration assumptions against Circle's USDC and EURC contract patterns, and avoid hard-coding any specific launch date into product copy or roadmaps. Circle's public statements are the only safe source.
​

Practical prep: identify which of your protocol's collateral parameters would change if a Circle-issued BTC asset listed alongside wBTC and cbBTC; model the cross-chain routing implications if cirBTC ships natively on Ethereum and Arc with later expansion; and watch Circle's blog and SEC filings (Circle is a public company as of June 2024) for regulatory updates that might signal approval progress. None of this requires a confirmed launch date.
