Blockchain development
Blockchain, down to the Layer-1.
Big Immersive is a blockchain and Web3 development company with studios in Lahore and Dubai. We design and build smart contracts, decentralised applications, wallets, bridges, staking, and block explorers on Ethereum and EVM-compatible networks — and we built Vanar Chain, an EVM Layer-1 that has produced more than 25 million blocks since 2023.

Discuss your projectWhat we build
Layer-1 infrastructure. Most blockchain studios deploy to someone else's network. We built one: Vanar Chain, an EVM-compatible Layer-1 with its own validator set, its own native token, and its own economics, producing a block every three seconds at a 30 million gas limit. Owning the chain meant owning everything underneath the application — block production, consensus, gas economics — and that is the depth we bring to projects that only need a small part of it.
The tooling a network is judged by. A chain with no explorer, no faucet, and no bridge is a private database with extra steps. Around Vanar we built the public block explorer, which indexes tens of millions of transactions and connects a wallet so visitors can use the contracts it lists, along with the faucet, the testnet, and a bridge from Ethereum.
Smart contracts and decentralised applications (dApps). Contracts in Solidity, with Rust where the target chain calls for it, designed for the audit cycle from the start rather than prepared for it at the end. Then the application a user actually touches: the Vanar Hub puts staking, the Ethereum bridge, a swap, and a rewards portal behind one wallet connection, with an add-to-wallet flow that registers the network for the visitor before anything else is attempted.
On-chain assets inside real products. In Virtua, ownable land plots and the generative robots that work them are on-chain assets with an economy running on top — resources, crafting, five rarity tiers — rather than NFTs that are pictures with a token attached. Tokenization is worth doing when the digital asset does something inside a product, and that is how we design it.

How we build it
Ethereum equivalence by default. Building on EVM-compatible networks means Solidity contracts and the ordinary Ethereum toolchain work unchanged, so a team never has to relearn the layer above the chain. Vanar was built the same way: Ethereum-equivalent execution, with the consensus layer customised for the throughput and cost the network targets.
Infrastructure alongside the contracts, not after. Explorers, indexing, faucets, and bridges are built in the same programme as the contracts they serve, because none of them can be bolted on once users have arrived.
Configuration, not forks. The Hub's wallet flow is written against the wallet provider's own methods rather than a heavy web3 framework, and the chain parameters are configuration, so pointing the same build at another network is an environment change rather than a rewrite.
Verifiable claims. Every figure we publish about our chain work can be checked by anyone with a wallet: the block time, the transaction count, and the chain ID are read from the running network, not from a slide.
How a project runs
Discovery first. We start with what the product needs from a chain — throughput, fees, the ecosystem your users are already in — and choose the network from that, rather than starting from a chain and fitting the product to it. Contract architecture and the security model are settled on paper, where they are cheap to change, before a line is deployed.
Then short, reviewable sprints on a testnet you can use at the end of each one, testing that includes the failure cases an attacker would look for, audit preparation, and a supported mainnet launch. We do not consider a milestone done until it meets the acceptance criteria we agreed.
We work from studios in Lahore and Dubai. Our chain work started inside our own products, so we have run what we built after launch, and we design for the cost of operating it from the start.

We build on Ethereum and EVM-compatible networks, and on purpose-built Layer-1s where a project needs its own chain rather than a shared one. Contracts are written in Solidity, with Rust where the target chain calls for it, and we use IPFS for off-chain assets. We select the network that matches your throughput, cost, and ecosystem needs.
Both. We built Vanar Chain, an EVM-compatible Layer-1 live since 2023 that has produced more than 25 million blocks at a three-second cadence, along with its explorer, bridge, staking, faucet, and testnet. Anyone can point a wallet at the network and check those figures.
Blockchain development is the chain and the contracts: the network itself, the smart contracts that run on it, and the infrastructure around them. Web3 development is the application layer people actually use — wallets, dApps, bridges, and on-chain assets. In practice a project needs both, and we build both, from a Layer-1 of our own up to the interface a holder taps.
We design and write smart contracts in Solidity, and in Rust where the chain calls for it, and we build them for the audit cycle from the start: clear ownership, minimal privileged paths, and tests for the failure cases an attacker would look for. For contracts that hold significant value we prepare the code for an independent audit rather than certifying our own work.
Usually not. Most products are better served by an existing EVM network, where the tooling, wallets, and users already are. A chain of your own earns its cost when you need control of fees, throughput, or validators that a shared network cannot give you — and we can tell you which side of that line you are on, because we have built on both.
Yes, and it is most of the work. Users touch wallets, bridges, dashboards, and explorers, not contracts. The Vanar Hub puts staking, a bridge from Ethereum, a swap, and rewards behind one wallet connection, and handles adding the network to a wallet that has never seen it.
Yes, when they do something inside the product. In Virtua, land plots and the robots that work them are on-chain assets with an economy behind them — resources, crafting, rarity tiers. We design token and asset systems around what the holder can actually do with them, and around the compliance constraints of your jurisdiction.
