BSK

Cross-chain bridges, engineered for you.

We design, develop and integrate Hyperlane-powered bridges across any EVM chain, including custom rollups, appchains and any ERC-20 / ERC-721 token. You own the infrastructure. You host. You hold the keys. We build the rails.

What we ship.

Engineering-only engagement. We deliver production-grade Hyperlane integrations, hand them over, and you take it from there. No SaaS. No tokens. No middlemen.

01

Any EVM chain

Ethereum, L2s, sidechains, custom rollups, OP Stack, Arbitrum Orbit, Polygon CDK, zk chains, appchains. If it speaks EVM, we bridge it.

  • → mainnets & L2s
  • → custom & private chains
  • → devnet → mainnet pipeline
02

Any token standard

ERC-20, ERC-721, ERC-1155, synthetic wrappers and collateralized routes. Native or warp-routed — your call.

  • → warp routes
  • → native & synthetic
  • → NFT bridging
03

Custom Interchain Security

Tailored ISM configurations — multisig, MerkleRoot, optimistic, aggregation. Pick your security model, we wire it in.

  • → multisig ISM
  • → aggregation ISM
  • → custom validators
04

UI & SDK integration

Bridge UI components, RPC layers, transaction relayers, and SDK glue — built into your dApp, your design system, your domain.

  • → React / Next.js modules
  • → wagmi / viem / ethers
  • → wallet adapters
05

You host. You own.

We do not host, custody or operate. Deliverables ship to your repo, your infra, your validators, your domain. Full sovereignty.

  • → source-code handoff
  • → infra-as-code optional
  • → zero vendor lock-in
06

Audit-ready delivery

Documented contracts, test coverage, deployment scripts, and operator runbooks — handed over ready for third-party audit.

  • → unit + fork tests
  • → deployment docs
  • → operator handbook
/02 — engagement flow

From spec to mainnet.
