Today, we’re thrilled to announce the mainnet launch of t1 Real-Time Proving (RTP), the first infrastructure enabling instant state proving across Ethereum rollups.
With this release, we introduce:
Real-time proving of state changes across Arbitrum and Base, improving capital efficiency and pricing in bridging and cross-chain swaps.
A TEE-enabled sealed-bid auction application that proves execution results to Arbitrum and Base in real time. TEE-enabled auctions increase price efficiency in cross-chain transactions and pave the way for composable cross-chain applications.
This marks the first step in our journey toward building a cross-chain application hub. As we prove the state of both t1 applications and other blockchains to all t1-supported chains, we unlock cross-chain contract calls, and ultimately, full cross-chain composability.
Fragmentation is the biggest problem in our space, and interop is not yet solved. As new chains launch almost daily—whether for stablecoins and payments (Arc by Circle, Tempo by Paradigm, Stable by Bitfinex/Tether) or for application-specific execution zones (Hyperliquid L1, Converge by Ethena)—fragmentation of users and liquidity will only get worse.
The only real solution is the ability to prove execution and state changes across chains in real time. With real-time proving, different execution environments can trust each other’s state instantly, allowing the entire ecosystem to behave like a single unified environment.
t1 is here to fix the fragmentation problem.
Today’s release is a small step toward our bigger vision of unification. With TEE-powered Real-Time Proving (RTP), t1 enables applications to instantly prove state across chains and unlock seamless cross-chain application flows for the first time.
This is how we bring money legos cross-chain.
And most importantly, t1 RTP is fully Ethereum-aligned. Our work is compatible with the Ethereum Foundation’s interop initiative, the Open Intents Framework. t1 RTP is the first TEE-powered oracle in the OIF’s ERC-7683 Intent Standard, and can also serve as an arbiter in the ERC-6909 Compact Framework, the new resource-lock standard from Uniswap Labs.
Today, we’re launching xChainRead, the primitive that brings Real-Time Proving between Base and Arbitrum to mainnet. This release focuses on improving ongoing interop efforts — ERC-7683 intents and resource locks:
Faster solver repayments (<6s vs. ~60 minutes on Across)
Higher capital efficiency (lower cost of capital for market makers)
Better pricing for end users
“We are excited about t1 RTP and sub-10 second settlements for bridging transactions. This advancement allows us to meet the same bridging demand while deploying significantly less capital — representing at least an order-of-magnitude improvement in capital efficiency. As our costs decrease, we will be able to pass those savings on, reducing the overall cost of bridging.”
Wee Howe, Tokka Labs CEO
There are three core primitives now available:
xChainReads allows developers to read and prove arbitrary state between Base and Arbitrum. Using xChainRead, other bridges can integrate t1 RTP to reduce their solver repayment time, increase solver capital efficiency, therefore improve pricing for their users.
If you are building your own bridge, using ERC-7683 intents or ERC-6909 Compact Resource Locks, you can access xChainRead documentation and get in touch with us for integration.
“Eco Routes pioneered modular proving and settlement for intents. For apps and for solvers, one proving method doesn’t necessarily fit all — but fast, trust-minimized settlement is imperative. This is where t1 RTP excels. It significantly improves capital efficiency for solvers, and in turn, delivers better prices for our users. We’re very excited to keep building with t1, and to integrate RTP with Eco Routes.”
**Ryne Saxe - Eco CEO**
A programmable sealed-bid auction powered by TEEs that:
Creates competitive bidding among solvers
Proves the winning bid + solver onchain in real time
Ensures instant on-chain settlement
This strengthens price discovery and transparency in cross-chain transactions.
If you’re a solver seeking transparent competition and real-time settlement, explore our documentation and get in touch with us to integrate with t1 RTP Bridge.
The t1 RTP Bridge combines Real-time Proving (xChainRead) and Sealed-Bid Auctions to deliver the most efficient cross-chain swap execution. From last week’s quiet mainnet testing:
Up to 6× cheaper bridging than Across
<6s solver repayment (vs. 60min Across)
If you are an aggregator looking to route through t1 RTP Bridge for best prices, check out our documentation and get in touch with us.
Faster repayments mean:
→ Higher capital efficiency and lower cost of capital for solvers
→ Better pricing for users
→ More volume for bridges & aggregators integrating RTP
→ More order flow and solver competition
→ Even better prices
This creates a positive feedback loop we call liquidity network effects — all powered by real-time state proving.
Real-time proving is just the beginning. We’re already building:
Programmable remote contract calls
Fully composable cross-chain applications
Cross-chain vaults and lending flows
Next time you hear from us, it will be about the first composable cross-chain application powered by t1.
If you’re building for the multichain world — t1 is for you.
Let’s unify Ethereum — one real-time proof at a time.
