t1 Protocol is a cross-chain application infrastructure that uses real-time proving and programmability to connect Ethereum with partner rollups, enabling instant settlement and seamless state sharing across chains.
By running full nodes rollup, and deploying expressive smart contracts on all connected chains, t1 allows developers to build composable, cross-chain applications and liquidity hubs without fragmenting user experience or liquidity.
On September 9th, 2024, the project announced a successful closure of its $2.5M Pre-Seed funding Round with participation from a16z crypto, Tokka Labs, and other angels.

t1 Labs has designed a cross-chain t1 Protocol that combines real-time proving with general-purpose programmability to unify Ethereum and partner rollups, and enable instant, verifiable settlement with compatibility across L2s. Using AVS-secured Intel TDX Trusted Execution Environments, t1 ensures all cross-chain execution is cryptographically verified, tamper-proof, and able to read from and write to multiple rollups without fragmenting liquidity or user experience.
Longer term, t1 will become a permissionless and decentralized network with the help of its technology stack:
Considering the long-term commitment, the project has developed 2 versions of its network architecture:
You can read more info in their docs.
🪙 t1 Protocol token: As of August 2025, the project hasn’t disclosed any info concerning the native token. However, there is an ongoing Testnet campaign, enabling users to prove anything between the Base and Arbitrum chains. This may bring us to the potential t1 Protocol airdrop shortly.
Based on the ongoing Testnet campaign, our team has completely analyzed the t1 Protocol, revealing several pros and cons:
✅ t1 Protocol pros:
❌ t1 Protocol cons:
t1 is an AVS-secured, TEE-powered infrastructure that delivers near-instant cross-chain execution with cryptographic integrity across Ethereum and rollups. Its evolving architecture moves from centralized real-time proving to a decentralized, ZKP-enhanced network for secure, scalable, and MEV-resistant interoperability.
On April 3rd, 2025, the project announced the launch of its Devnet, where users can use the t1 bridge for instant deposits & withdrawals between t1 and L1. Moreover, on June 26th, Proof of Read testnet became live, allowing users to prove anything between Arbitrum and Base chains.
