About 1sec

1Sec is a message-passing bridge between ICP and EVM chains.

Description sourced from DeFiLlama's protocol metadata; teams submit their own copy when listing.

How 1sec's TVL is measured

DeFiLlama publishes the exact rules used to aggregate on-chain balances into the headline TVL figure shown on this page. The methodology below is the team's own source-of-truth description.

TVL counts tokens where collateral is custodied: ICP-native tokens on ICP chain, and EVM-native tokens locked in the locker contract on their respective EVM chains.

If a contract or vault isn't in this list, its balance does not contribute to the TVL displayed on Mantapex or DeFiLlama.

Protocol Footprint

1sec operates on 4 networks (ICP, Ethereum, Base, Arbitrum), keeping its surface area narrower than chain-agnostic peers. Roughly 100% of its on-chain value sits on just three networks (ICP, Ethereum, Base), so a fault on any one of them would affect a large slice of users.
