Smart contracts have never had full context.

They can’t access historical state.

They can’t compute across multiple blocks.

They can’t react to events without relying on indexers or costly oracles.

And no matter what you’re building, there’s a hard ceiling you can’t break: Ethereum’s 30M gas limit.

EVM developers have been building in a tunnel: cut off from the past, unable to see across time, forced to trust third-party infrastructure, and always constrained by how much computation can fit in a single block.

Steel on Boundless changes that.

Steel is a ZK-coprocessor for the EVM that plugs right into Boundless. It offloads execution offchain, where you can aggregate data, run complex logic, or compute across time, then return just a tiny proof onchain. Your EVM contract can then verify it in constant gas, regardless of how much computation you do.

The three primitive beneath it all

• Event logs as inputs, verified and trustless
• Historical state from any block since Dencun
• Multi-block logic that spans time ranges, not just single blocks

All offloaded off-chain. All verifiable on-chain. All while still using Solidity for your core logic.

This unlocks a new design space for EVM apps: Contracts that can extend beyond a single block, react to events, reason over history, and break free from block size limits.
