Service / Web3
Cross-chain products without a single point of failure.
Bridges, messaging, intents and chain abstraction across Ethereum L2s, Solana and beyond, with verification that does not hang on one node or one key.
[ 01 ]The short answer
What is Cross-Chain and Interoperability?
Cross-chain development connects applications and assets across blockchains: token bridges, generalised messaging, intent-based transfers where solvers fill orders, and chain abstraction that hides the chain from the user. It is also where some of the largest losses happen: the April 2026 Kelp DAO exploit drained about $292 million through a bridge configured with a single verifier. We design with multiple independent verifiers, rate limits, and intents and canonical routes chosen by value at risk.
What you get
- Interop architecture and threat model
- Contracts and programs on each chain
- Verifier and rate-limit configuration
- Monitoring and pause automation
- Runbooks for incident response
[ 02 ]What we build
The pieces, built to last.
- 01
Token deployment across chains
Native-burn-and-mint or lock-and-mint designs with supply invariants checked across chains.
- 02
Messaging
Cross-chain calls over LayerZero, Wormhole, CCIP or Hyperlane, configured with several verifiers.
- 03
Intents
ERC-7683 style orders filled by solvers, so users get speed without trusting a bridge.
- 04
Chain abstraction
Unified balances and one-click actions across chains in your app.
- 05
Rate limits and monitoring
Per-route caps and alerts on unusual flows, with automatic pause.
- 06
Solana and EVM
Assets and messages between Solana and EVM chains, including USDC via CCTP.
[ 03 ]Where it pays off
Where it earns its keep.
- 01
Multi-chain tokens
One token, many chains, one supply.
- 02
Cross-chain DeFi
Deposits from anywhere into one protocol.
- 03
Payments
Pay on the chain you hold funds, settle on the chain the merchant uses.
- 04
Wallets and apps
Users see one balance, not twelve.
[ 04 ]How we deliver
Four steps, one team, start to finish.
The same people scope it, build it and stay after launch. Timings are typical for a first release; we agree yours after the deep dive.
- 01Week 1
Threat model and spec
Who can move money, under what conditions, and what happens when a key, an oracle or a bridge fails. Written down before code.
- 02Weeks 2 to 8
Build with invariants
Contracts or programs with unit, fuzz and invariant tests, least-privilege roles, timelocks and rate limits from the first commit.
- 03Weeks 6 to 10
Review and testnet
Internal review, an independent audit where value is at stake, and a public testnet with monitoring wired in.
- 04Ongoing
Mainnet and watch
A staged launch with caps, live alerting on admin actions and outflows, and a rehearsed incident plan.

[ 08 ]FAQ
Questions buyers ask.
The configuration matters as much as the protocol. A strong protocol with one verifier is weak. We use several independent verifiers and caps sized to value at risk.
For users, often yes: the solver takes the bridging risk and users get funds quickly. Settlement still relies on a verification layer, which we design carefully.
Yes, for tokens, messages and USDC, with the different finality models of each chain accounted for.
