From a chain to a dApp, from token launch to listing — one-stop delivery
Infrastructure L1 / L2 / Bridges / Nodes
Custom L1 Blockchain
Straight answer: most projects don't need their own chain. If you do — compliance, throughput, or an economy you control — we build it on Cosmos SDK or Substrate, from consensus tuning to mainnet.

Layer2 Rollup Launch
Spinning up an OP Stack chain takes weeks. Getting anyone to use it takes longer. We build the sequencer, bridge and explorer, and we'll ask the harder question first.

Cross-Chain Bridge
Bridges are the most-hacked surface in this industry. We stick to lock-mint and liquidity-pool designs, no clever tricks, and wire up monitoring so you know in the first minute.

Node / RPC Clusters
Full nodes, archive nodes, load-balanced RPC, plus Grafana and alerting. The thing people misjudge is how fast archive-node storage grows — we size that up front.

Smart Contract Development
This is the work we take on most. Solidity and Rust, test coverage above 95%, and the deployment scripts are yours, so you can redeploy without coming back to us.

Digital Asset Issuance Kit
Token contract, vesting, Merkle airdrop, multisig treasury — everything you need on issuance day day. The parts that actually bite are release schedules and who holds which key, so we go over them twice.

Security Audit (Partner Firms)
The report comes from a top-tier audit firm we partner with, not from us marking our own homework. We pre-audit internally first, which saves you the round-by-round rework fee.

DeFi & Trading DEX / Lending / Staking / issuance platform
DEX / AMM Exchange
One question before anything else: where does liquidity come from? We build V2/V3-style pools, fees, oracles and mining, but cold-start capital and market makers are on you.

DeFi Lending Protocol
Lending protocols live or die on liquidation. Rate models, liquidation incentives and flash loans are all buildable; we spend the most time on liquidation parameters and oracle choice, because that's where most failures start.
