# For DeFi/Rollup Devs

Continuum is chain-agnostic. Drop-in adapters exist for Solidity (Uniswap v4 hooks, RFQ routers), Rust/Anchor (OpenBook v2 gated pools), and CosmWasm modules. A typical integration requires:

1. Importing the core verification library (≈200 LOC in most runtimes).
2. Replacing your contract’s *msg.sender* or *clock.slot* ordering routine with requireValidSequence(root, proof, seqNum).
3. Optionally subscribing to the public Sequencer Mesh so your front-end or relayer always submits proofs alongside user intents.

Because proofs are constant-size (1.6 kB Wesolowski), gas overhead is modest—​35 k on Ethereum L1, far less on L2s. The same FIFO guarantees that secure Fermi trades can now secure batch auctions, per-block oracle updates, or cross-chain bridge queues, eliminating an entire class of MEV exploits at the middleware layer.
