Bullbit Opens BullChain Testnet With Native Passkey Support
Bullbit announced the public launch of the BullChain Testnet on September 3, 2026. The network is a Layer 1 built for on-chain trading, with passkey support built into its core. The launch follows five months of private testing, during which Bullbit reports that the network reached up to 10,000 transactions per second.
BullChain Opens Public Access After Private Testing
The project began its invitation-only testing program, “The Stress Test Arena,” in March 2026. It brought together approved users and selected key opinion leaders to try the network under controlled conditions.
Over the following months, the team gathered feedback, tracked faults and tested how the network handled more activity. The public phase now expands that work to a wider group of users, devices and trading habits.
According to Bullbit, users can join without an invitation code and claim test tokens through the faucet. The aim is to test the network and improve the trading experience before mainnet.
How Native Passkeys Support On-Chain Trading
Bullbit describes BullChain as a passkey-native Layer 1. Readers who want more context on base networks can explore this Layer 1 blockchain guide.
The company says the network supports both EVM-compatible and passkey-based signatures at the protocol level. On supported devices, users can approve actions with familiar methods such as Face ID or Touch ID.
Bullbit positions the network as the first of its kind. That is the project's claim; this article does not establish an independent comparison of all passkey-enabled blockchains.
Passkey Verification at the Network Level
Many smart wallet designs add account features through smart contracts. BullChain instead aims to handle passkey verification within its core network rules. Understanding blockchain layers helps explain where these functions sit within a network.
Bullbit says this design can reduce the extra processing needed for smart wallet functions and bring their gas costs close to zero. This claim should not be read as a promise that every mainnet transaction will be free.
Native passkey support may simplify signing, but it does not remove all security risks. The network code, device security and account recovery process still matter.
Bullbit Reports 10,000 TPS in Private Testnet Trials
During private stress tests, Bullbit reports peak throughput of 10,000 transactions per second, or TPS. The company also reports latency of about 100–200 milliseconds.
These figures describe results from a test environment. They do not establish sustained public-network capacity or guarantee the same performance after mainnet launch.
Throughput measures how many transactions a network handles. Latency measures delay, though the exact result depends on where measurement starts and ends. The reported latency should not be treated as confirmed time to final settlement without further technical detail.
Fast responses can matter for active trading, including short-term strategies such as scalping. However, execution speed alone does not ensure a profitable trade or remove market risk.
Community Testing and BullChain Bug Bounty Details
Bullbit announced a 1,000 USDC bug bounty program scheduled from September 4 to October 4, 2026. Its announcement names HackenProof and First Dollar as reporting platforms.
The linked HackenProof page currently describes a QA testing program, lists rewards of $10–$50 and excludes security vulnerabilities from that program's scope. Participants should check the current rules on each platform before testing or submitting reports.
The overall campaign pool is separate from any individual reward. Payment depends on the relevant program's eligibility rules and acceptance of the report.
Community feedback can help the team find display faults, connection problems and other issues across more devices. That feedback will also help refine the public testnet before the next development stage.
How to Join the Testnet and Follow Mainnet Plans
Users can find the testnet portal through Bullbit's official launch announcement. The published process involves setting up passkey access, claiming faucet tokens and trying test trades.
- Open the testnet portal listed in Bullbit's official announcement.
- Follow the passkey setup steps for your supported device.
- Claim test tokens from the faucet.
- Try the available features and report issues within the relevant program's scope.
Faucet tokens are intended for testing. Participation should not be presented as a confirmed token airdrop or a promise of future rewards.
Bullbit targets Q4 2026 for the BullChain mainnet launch. This remains a planned window, rather than a confirmed launch date.
