1sec

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

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.

1sec is a Bridge protocol that moves assets and messages between blockchains, locking value on the source chain and minting or releasing a representation on the destination. It is deployed across 4 chains, including ICP, Ethereum, Base, Arbitrum. No public audit reports are listed on DeFiLlama for this protocol.

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.

1sec is one of 7 Bridge protocols Mantapex tracks in this category. Direct peers ranked by total value locked include WBTC, Coinbase Bridge, Binance Bitcoin, and 3 more. These peer protocols collectively secure US$303.9亿 in deposits, giving you a frame of reference for whether 1sec's own TVL is at the top, middle, or tail of the category.
